We'll cover everything from basic troubleshooting to more advanced network configurations, so you can confidently tackle this problem. Getting your Synology NAS back up and running is crucial, especially if you rely on it for file storage, media streaming, backups, or any other important tasks. This guide will help you identify the common culprits and provide step-by-step solutions to get you back on track. Let’s dive in and get your NAS talking to your network again!
Understanding the Problem: Why Can't I Access My NAS?
Before we jump into solutions, let's understand why this happens in the first place. When you move and change your network setup, several things can go awry. Your NAS, like any other network device, relies on an IP address to communicate within your network. Your router assigns these IP addresses, and it's possible that your NAS has been assigned a new one, or the network settings are simply not configured correctly. Think of it like your NAS having a new home address, but your computer doesn't know the new address yet! Here are some of the most common reasons why you might be experiencing this issue:
- IP Address Change: Your router might have assigned a new IP address to your NAS. This is the most frequent cause. Routers often use DHCP (Dynamic Host Configuration Protocol) to automatically assign IP addresses, and a new network setup can trigger this process, resulting in a different IP address for your NAS. For example, your NAS might have had an IP address of 192.168.1.10 on your old network, but now it's 192.168.1.15 on your new network. If your computer is still trying to connect to the old address, it won't be able to reach the NAS.
- Subnet Mismatch: Your NAS and your computer might be on different subnets. A subnet is a logical subdivision of an IP network. If your NAS and computer are on different subnets, they won't be able to communicate. This can happen if your new router has a different default subnet than your old one.
- Firewall Issues: Your router's or computer's firewall might be blocking access to the NAS. Firewalls are designed to protect your network and devices from unauthorized access, but sometimes they can be overly restrictive. If your firewall is blocking the NAS's traffic, you won't be able to connect to it.
- Network Cable Problems: A loose or damaged network cable can prevent your NAS from connecting to the network. It's always a good idea to double-check your cables to make sure they're securely plugged in and not damaged.
- Synology Account Issues: Although less common, there might be issues with your Synology account or the NAS's configuration that are preventing access. This could be related to account settings, permissions, or other configurations within the Synology DSM (DiskStation Manager) operating system.
Understanding these potential causes is the first step in resolving the issue. Now, let's get into the troubleshooting steps!
Step-by-Step Troubleshooting: Getting Your NAS Back Online
Okay, let’s get down to business and troubleshoot this issue. We'll start with the simplest solutions and move towards more advanced ones. Remember to test your connection after each step to see if the problem is resolved. Patience is key here, guys! Sometimes it takes a few tries to nail down the exact cause.
1. Check the Basics: Power and Network Cables
This might seem obvious, but it’s always a good idea to start with the basics. Make sure your NAS is powered on and that all the network cables are securely connected to both the NAS and your router. A loose cable is a surprisingly common culprit! Look for the network activity lights on both the NAS and your router. If they're blinking, it means there's some activity, which is a good sign. If not, try a different cable or port to rule out a faulty connection. Ensure the power cable is firmly plugged into the NAS and the power outlet. Sometimes, a simple disconnection can occur during a move, causing the NAS to appear offline. Similarly, a malfunctioning Ethernet cable can disrupt the network connection. Try using a different cable to see if it resolves the issue. It’s also wise to try a different port on your router. Faulty ports can sometimes prevent devices from connecting to the network. By systematically checking these basic connections, you can eliminate the most common and easily fixable causes of the problem. This proactive approach can save you from spending time on more complicated solutions when a simple fix is all that’s needed. By verifying the power and network cables first, you can quickly identify and resolve any connectivity issues, setting the stage for more advanced troubleshooting if necessary.
2. Find the NAS's New IP Address
This is the most crucial step! We need to figure out what IP address your NAS is using on your new network. There are a few ways to do this:
- Synology Assistant: This is the easiest method. Download and install the Synology Assistant utility on your computer.

- Router's Admin Interface: Log in to your router's admin panel (usually by typing its IP address in your web browser, like 192.168.1.1 or 192.168.0.1). Look for a section called “DHCP Clients,” “Attached Devices,” or something similar. You should see a list of devices connected to your network, including your NAS. The NAS will be listed by its name (e.g., DiskStation) or MAC address. Accessing your router’s admin interface is another reliable way to find the IP address of your Synology NAS. Most modern routers have a web-based interface that allows you to manage network settings, view connected devices, and configure various options. To access the router’s admin panel, you typically need to enter the router’s IP address into your web browser’s address bar. Common router IP addresses include 192.168.1.1, 192.168.0.1, and 192.168.2.1, but the exact address may vary depending on your router’s manufacturer and settings. Once you’ve accessed the admin panel, you’ll need to log in using your router’s username and password. The default credentials are often printed on a sticker on the router itself, or you can find them in your router’s documentation. After logging in, navigate to the section that lists connected devices. This is often labeled as “DHCP Clients,” “Attached Devices,” “Device List,” or something similar. Here, you’ll see a list of all devices currently connected to your network, along with their IP addresses, MAC addresses, and hostnames. Look for your Synology NAS in the list. It will usually be identified by its name (e.g., DiskStation) or its MAC address. The MAC address is a unique identifier assigned to your NAS’s network interface, and you can find it on a sticker on the NAS device itself. Once you’ve located your NAS in the list, you’ll see its current IP address. This is the address you’ll need to use to connect to your NAS from your computer or other devices on your network. If you’re having trouble finding your NAS in the list, try sorting the devices by IP address or hostname to make it easier to locate. The router's admin interface provides a comprehensive overview of your network and is a valuable tool for managing your devices and troubleshooting connectivity issues.
- IP Scanner Tools: There are many free IP scanner tools available online (like Angry IP Scanner). These tools scan your network and list all devices with their IP addresses.

IP scanner tools are software applications designed to scan a network and identify all active devices along with their IP addresses and other network information. These tools are invaluable for network administrators and anyone troubleshooting network connectivity issues. They work by sending out network packets to a range of IP addresses and then listening for responses. When a device responds, the tool records its IP address, MAC address, hostname, and other relevant details. There are many free and commercial IP scanner tools available, each with its own set of features and capabilities. Popular options include Angry IP Scanner, Advanced IP Scanner, and Nmap. These tools are user-friendly and can quickly scan a network, providing a comprehensive list of connected devices. Using an IP scanner tool is particularly helpful when you need to identify all devices on your network, not just the ones that are currently connected. This can be useful for auditing your network, identifying unauthorized devices, or troubleshooting IP address conflicts. To use an IP scanner tool, you typically need to specify the IP address range to scan. This range is usually based on your network’s subnet. For example, if your network’s IP address range is 192.168.1.1 to 192.168.1.254, you would specify this range in the tool. The tool will then scan each IP address in the range and display the results. Once the scan is complete, you can review the list of devices and look for your Synology NAS. The NAS will usually be identified by its hostname (e.g., DiskStation) or its MAC address. The IP scanner tool provides a detailed view of your network’s devices and is an essential tool for diagnosing connectivity problems. If you’re unable to find your NAS using Synology Assistant or your router’s admin interface, an IP scanner tool can be a valuable alternative.
3. Connect to Your NAS via Web Browser
Once you have the new IP address, open your web browser and type http://[NAS IP Address]:5000 (replace [NAS IP Address] with the actual IP address). If you see the Synology DiskStation Manager (DSM) login page, congratulations! You're halfway there. This means your computer can communicate with the NAS. This step is crucial because it verifies whether your computer can communicate with your Synology NAS over the network. The default port for accessing the Synology DSM via a web browser is port 5000 for HTTP and port 5001 for HTTPS. By typing the NAS’s IP address followed by :5000 in your web browser, you are attempting to establish a connection to the NAS’s web interface. If the connection is successful, you will see the Synology DSM login page, indicating that the NAS is reachable and functioning correctly. If you don’t see the login page, it suggests that there may be a network connectivity issue or that the NAS is not properly configured. In this case, you should double-check the IP address you entered, ensure that your computer and NAS are on the same network, and verify that there are no firewall rules blocking the connection. Additionally, make sure that the NAS is powered on and connected to the network via an Ethernet cable. If you’re still unable to connect, try clearing your browser’s cache and cookies or using a different web browser. Sometimes, cached data or browser extensions can interfere with the connection. If you are able to access the DSM login page, it’s a positive sign that the NAS is accessible. However, it’s still important to ensure that you can access your files and folders and that all services are functioning correctly. After logging in to the DSM, you should check the network settings, storage volumes, and other configurations to ensure that everything is set up as expected. If you encounter any issues, refer to the Synology documentation or online resources for troubleshooting tips. Connecting to your NAS via a web browser is a fundamental step in diagnosing and resolving connectivity issues. It helps you confirm whether the NAS is reachable on the network and provides access to the DSM, where you can manage and configure the NAS’s settings. This initial connection is essential for further troubleshooting and ensuring that your NAS is functioning properly.
4. Set a Static IP Address (Recommended)
To prevent this issue from happening again, it's highly recommended to set a static IP address for your NAS. This means the NAS will always use the same IP address, regardless of your router's DHCP settings. Here’s how:
- Log in to your Synology DSM.
- Go to Control Panel > Network > Network Interface.
- Select your LAN connection and click Edit.
- Choose “Use manual configuration.”
- Enter a static IP address (within your network's range but outside the DHCP range – check your router's settings for this), subnet mask, gateway, and DNS server.
Setting a static IP address for your Synology NAS is a crucial step in ensuring consistent network accessibility and preventing future connection issues. By default, most routers use DHCP to dynamically assign IP addresses to devices on the network. While this is convenient for most devices, it can cause problems for devices like NAS servers that need to be consistently accessible. When your router assigns an IP address dynamically, it may change the address periodically, especially after a network restart or if the device is disconnected and reconnected. This can lead to situations where you can’t access your NAS because its IP address has changed and your computer is still trying to connect to the old address. To avoid this, setting a static IP address ensures that your NAS always has the same IP address, making it consistently accessible on your network. To set a static IP address, you need to access the Synology DSM (DiskStation Manager) interface. This is the web-based operating system for your NAS. Log in to the DSM using your administrator credentials. Once you’re logged in, navigate to the Control Panel, which is the central hub for managing your NAS’s settings. In the Control Panel, go to the Network section. This is where you’ll find all the settings related to your NAS’s network configuration. Within the Network section, select Network Interface. Here, you’ll see a list of your NAS’s network interfaces, typically labeled as LAN 1, LAN 2, etc. Select the LAN connection that you’re using to connect your NAS to your network and click Edit. In the Edit window, you’ll see options for configuring the network interface. Choose the “Use manual configuration” option. This will allow you to manually enter the IP address, subnet mask, gateway, and DNS server settings. Now, you need to enter the static IP address for your NAS. Choose an IP address within your network’s range but outside the DHCP range. The DHCP range is the range of IP addresses that your router uses for dynamic assignment. To find out your router’s DHCP range, you’ll need to access your router’s admin interface. This is typically done by entering your router’s IP address in a web browser. The DHCP range is usually listed in the router’s DHCP settings. When choosing a static IP address, it’s best to select an address that’s outside this range to avoid conflicts. For example, if your router’s DHCP range is 192.168.1.100 to 192.168.1.200, you could choose a static IP address like 192.168.1.25. Next, enter the subnet mask for your network. The subnet mask defines the size of your network. For most home networks, the subnet mask is 255.255.255.0. Then, enter the gateway IP address. The gateway is the IP address of your router, which acts as the gateway to the internet. Finally, enter the DNS server IP addresses. DNS servers translate domain names (like google.com) into IP addresses. You can use your router’s IP address as the primary DNS server, or you can use public DNS servers like Google’s (8.8.8.8 and 8.8.4.4) or Cloudflare’s (1.1.1.1). Once you’ve entered all the settings, click OK to save your changes. Your NAS will now use the static IP address you’ve configured. After setting a static IP address, it's wise to reserve it on your router. This prevents other devices from being assigned the same IP address, ensuring that your NAS always has exclusive use of its static IP. You can usually reserve an IP address in your router’s DHCP settings. By setting a static IP address, you can significantly improve the reliability and accessibility of your Synology NAS. This ensures that you can always connect to your NAS without having to worry about IP address changes. It’s a simple yet effective way to maintain a stable network connection for your NAS and prevent future connectivity issues.
5. Check Firewall Settings
Your computer's or router's firewall might be blocking access to the NAS. Make sure your firewall isn't blocking connections on port 5000 (or 5001 for HTTPS). Temporarily disabling your firewall can help you determine if this is the issue. Remember to re-enable it once you've tested the connection. Firewall settings play a critical role in network security, but they can sometimes interfere with legitimate connections, such as those to your Synology NAS. Firewalls are designed to protect your network and devices from unauthorized access by filtering incoming and outgoing network traffic based on predefined rules. If your firewall is blocking connections on the ports used by your NAS, you won’t be able to access it from your computer or other devices on your network. The default port for accessing the Synology DSM via a web browser is port 5000 for HTTP and port 5001 for HTTPS. These ports are used for the web interface that allows you to manage and configure your NAS. If your firewall is blocking traffic on these ports, you won’t be able to connect to the DSM. To check your firewall settings, you’ll need to access the firewall configuration on your computer or router. The steps for doing this will vary depending on your operating system and router model. On Windows, you can access the firewall settings by going to Control Panel > System and Security > Windows Defender Firewall. On macOS, you can access the firewall settings by going to System Preferences > Security & Privacy > Firewall. In the firewall settings, you should look for rules that might be blocking connections on ports 5000 and 5001. You may need to create an exception or allow rule for these ports to ensure that your computer can communicate with your NAS. If you’re not sure how to configure your firewall, you can temporarily disable it to see if it’s the cause of the issue. However, it’s important to re-enable your firewall as soon as you’ve tested the connection, as disabling your firewall can leave your computer vulnerable to security threats. To temporarily disable your firewall on Windows, go to Control Panel > System and Security > Windows Defender Firewall and click “Turn Windows Defender Firewall on or off.” On macOS, go to System Preferences > Security & Privacy > Firewall and click “Turn Off Firewall.” After disabling your firewall, try connecting to your NAS via a web browser by typing its IP address followed by :5000 or :5001 in the address bar. If you can access the DSM login page after disabling your firewall, it indicates that the firewall is blocking the connection. In this case, you’ll need to configure your firewall to allow traffic on the necessary ports. To configure your firewall, you can create an exception or allow rule for ports 5000 and 5001. This will allow your computer to communicate with your NAS without compromising your network security. You may also need to check your router’s firewall settings. Most routers have a built-in firewall that can block incoming and outgoing traffic. To access your router’s firewall settings, you’ll need to log in to your router’s admin interface. The steps for doing this will vary depending on your router model, but you typically need to enter your router’s IP address in a web browser. Once you’ve logged in, look for the firewall settings in the router’s admin panel. You may need to create a port forwarding rule to allow traffic on ports 5000 and 5001 to be forwarded to your NAS’s IP address. Port forwarding allows incoming traffic on specific ports to be directed to a specific device on your network. By checking and configuring your firewall settings, you can ensure that your computer and NAS can communicate without being blocked by security rules. This is an important step in troubleshooting connectivity issues and maintaining a secure network environment.
6. Subnet Mask and Gateway Settings
If you're still having trouble, double-check that your NAS and computer are on the same subnet. The subnet mask should be the same for both devices (usually 255.255.255.0 for home networks). Also, make sure the gateway IP address on your NAS is set to your router's IP address. Incorrect subnet mask or gateway settings can prevent devices from communicating on the network. Subnet mask and gateway settings are critical components of network configuration, and incorrect settings can prevent devices from communicating with each other on the network. A subnet mask is a 32-bit number that defines the size of a network by indicating which part of an IP address represents the network and which part represents the host. The gateway IP address is the IP address of the router, which acts as the gateway between your local network and the internet or other networks. To ensure that your NAS and computer can communicate with each other, they must be on the same subnet and have the correct gateway IP address configured. If the subnet masks are different, or if the gateway IP address is incorrect, the devices won’t be able to route traffic to each other, resulting in connectivity issues. To check the subnet mask and gateway settings on your NAS, you need to access the Synology DSM (DiskStation Manager) interface. Log in to the DSM using your administrator credentials. Once you’re logged in, navigate to the Control Panel, which is the central hub for managing your NAS’s settings. In the Control Panel, go to the Network section. This is where you’ll find all the settings related to your NAS’s network configuration. Within the Network section, select Network Interface. Here, you’ll see a list of your NAS’s network interfaces, typically labeled as LAN 1, LAN 2, etc. Select the LAN connection that you’re using to connect your NAS to your network and click Edit. In the Edit window, you’ll see the subnet mask and gateway IP address settings. Verify that the subnet mask is correct. For most home networks, the subnet mask is 255.255.255.0. If you have a different subnet mask, it may indicate a more complex network configuration. Also, verify that the gateway IP address is set to your router’s IP address. To find out your router’s IP address, you can check your router’s documentation or use a network diagnostic tool. If the subnet mask or gateway IP address is incorrect, correct it and save the changes. Next, you need to check the subnet mask and gateway settings on your computer. The steps for doing this will vary depending on your operating system. On Windows, you can check these settings by opening the Command Prompt and typing ipconfig. The subnet mask and default gateway IP address will be listed in the output. On macOS, you can check these settings by going to System Preferences > Network, selecting your network interface, and clicking “Advanced.” The subnet mask and router IP address will be listed in the TCP/IP tab. Verify that the subnet mask and gateway IP address on your computer match the settings on your NAS. If they don’t, correct them and save the changes. If you’re still having trouble connecting to your NAS after verifying the subnet mask and gateway settings, there may be other network configuration issues. In this case, you may need to consult your network documentation or seek assistance from a network professional. Incorrect subnet mask and gateway settings are a common cause of network connectivity issues, so it’s important to verify these settings when troubleshooting network problems. By ensuring that your NAS and computer are on the same subnet and have the correct gateway IP address configured, you can prevent many common connectivity issues and ensure that your devices can communicate effectively on your network.

By ensuring that your router is compatible with your NAS and that its firmware is up to date, you can prevent many common connectivity issues and maintain a stable network connection for your NAS.
2. Check for IP Address Conflicts
It's possible that another device on your network has the same IP address as your NAS. This can cause conflicts and prevent your NAS from being accessible. Try changing your NAS's IP address (even if it's static) to see if this resolves the issue. IP address conflicts occur when two or more devices on the same network are assigned the same IP address. This can cause significant network connectivity issues, as devices may be unable to communicate properly or may experience intermittent disconnections. IP addresses are unique identifiers that allow devices to communicate with each other on a network. When two devices have the same IP address, it creates a conflict that prevents network traffic from being routed correctly. IP address conflicts can be caused by several factors, including manual IP address assignment, DHCP server issues, or misconfigured network settings. If you’re experiencing connectivity issues with your Synology NAS, it’s important to check for IP address conflicts as part of the troubleshooting process. To check for IP address conflicts, you can use several methods, including network diagnostic tools, command-line utilities, or your router’s admin interface. Network diagnostic tools, such as Angry IP Scanner or Advanced IP Scanner, can scan your network and identify all active devices along with their IP addresses. If you see the same IP address listed for multiple devices, it indicates an IP address conflict. Command-line utilities, such as ping and arp, can also be used to diagnose IP address conflicts. The ping command can be used to test network connectivity by sending packets to a specific IP address. If you receive responses from multiple devices when pinging a single IP address, it indicates an IP address conflict. The arp command can be used to display the ARP (Address Resolution Protocol) cache, which maps IP addresses to MAC addresses. If you see multiple MAC addresses associated with the same IP address in the ARP cache, it indicates an IP address conflict. Your router’s admin interface can also provide information about connected devices and their IP addresses. Log in to your router’s admin interface and look for the DHCP client list or device list. This list will show all devices that have been assigned IP addresses by the router. If you see the same IP address listed for multiple devices, it indicates an IP address conflict. If you identify an IP address conflict, you’ll need to resolve it to restore network connectivity. The most common way to resolve an IP address conflict is to change the IP address of one of the conflicting devices. If your NAS is using a static IP address, you can change it to a different IP address within your network’s range. Make sure to choose an IP address that is not being used by any other device on the network. If your NAS is using DHCP, you can try releasing and renewing its IP address. This will force the NAS to request a new IP address from the DHCP server, which may resolve the conflict. You can also try assigning a static IP address to your NAS to prevent future IP address conflicts. When assigning a static IP address, choose an IP address outside the DHCP range to avoid conflicts with dynamically assigned addresses. In addition to changing IP addresses, you can also try restarting the conflicting devices. This can sometimes resolve IP address conflicts by clearing the ARP cache and forcing devices to request new IP addresses. IP address conflicts can cause significant network connectivity issues, so it’s important to check for them when troubleshooting network problems. By using network diagnostic tools, command-line utilities, or your router’s admin interface, you can identify IP address conflicts and take steps to resolve them.
3. Reset Your NAS (As a Last Resort)
If all else fails, you can try resetting your NAS to its factory defaults. This will erase all your settings, so use this as a last resort! There are usually two types of resets: a mode 1 reset (which resets the admin password and network settings) and a mode 2 reset (which reinstalls the DSM). Refer to your Synology NAS's documentation for instructions on how to perform a reset. Resetting your NAS to its factory defaults should be considered as a last resort when all other troubleshooting steps have failed to resolve the issue. A factory reset will erase all your settings, including network configurations, user accounts, and shared folders, and revert the NAS to its original state. Therefore, it’s crucial to back up your data before performing a factory reset to prevent data loss. There are two types of resets available on Synology NAS devices: Mode 1 reset and Mode 2 reset. Each reset mode performs a different level of reset and addresses specific issues. Mode 1 Reset: This type of reset is primarily used to reset the administrator password and network settings. It’s useful when you’ve forgotten the administrator password or when you need to reconfigure the network settings due to changes in your network environment. A Mode 1 reset will not erase your data or installed packages, but it will reset the NAS’s hostname, IP address, DNS server, and other network-related settings to their default values. To perform a Mode 1 reset, you typically need to press and hold the reset button on the back of your NAS for a specific duration (usually around 4 seconds) until the status LED starts blinking. Refer to your Synology NAS’s documentation for the exact steps and duration. After the Mode 1 reset, you’ll need to use Synology Assistant or the web interface to reconfigure the NAS’s network settings and set a new administrator password. Mode 2 Reset: This type of reset performs a more comprehensive reset, including reinstalling the Synology DSM (DiskStation Manager) operating system. It’s used when you’re experiencing severe issues with the NAS, such as system errors, performance problems, or when you want to completely wipe the NAS and start fresh. A Mode 2 reset will erase all your data, settings, and installed packages, effectively returning the NAS to its factory default state. Before performing a Mode 2 reset, it’s essential to back up all your data, as it will be permanently erased. To perform a Mode 2 reset, you typically need to press and hold the reset button on the back of your NAS for a longer duration (usually around 10 seconds) until the status LED starts blinking rapidly. Refer to your Synology NAS’s documentation for the exact steps and duration. After the Mode 2 reset, you’ll need to use Synology Assistant to reinstall the DSM operating system and reconfigure your NAS from scratch. The steps for performing a reset may vary slightly depending on your Synology NAS model, so it’s crucial to refer to your NAS’s documentation for detailed instructions. The documentation provides specific guidance on the reset button location, the duration for pressing the button, and the expected LED behavior for each reset mode. Before performing a reset, make sure you understand the implications of each reset mode and choose the appropriate reset mode based on your specific issue. If you’re unsure which reset mode to use, it’s best to start with a Mode 1 reset, as it’s less drastic and will not erase your data. Resetting your NAS should only be considered as a last resort after exhausting all other troubleshooting options. Before performing a reset, make sure to back up your data and consult your NAS’s documentation for detailed instructions. By understanding the different reset modes and their implications, you can effectively troubleshoot issues with your Synology NAS and restore it to a working state.

Troubleshooting network connectivity issues can be a frustrating experience, but with a methodical approach and a bit of patience, you can often resolve the problem and get your devices back online. The key is to start with the basics, systematically check each potential cause, and try different solutions until you find the one that works. When dealing with Synology NAS devices, moving and changing your network setup can often lead to connectivity issues, as the NAS’s IP address and network configurations may need to be updated to match the new network environment. However, by following the troubleshooting steps outlined in this guide, you can effectively diagnose and resolve these issues. The first step is to ensure that all the basic connections are in place. Check the power cord, Ethernet cable, and network ports to make sure everything is securely connected. A loose cable or a malfunctioning port can often be the culprit behind connectivity problems. Once you’ve verified the basic connections, the next step is to find the NAS’s new IP address. This can be done using Synology Assistant, your router’s admin interface, or an IP scanner tool. Synology Assistant is a particularly useful tool, as it’s designed specifically for locating Synology devices on the network. After you’ve found the NAS’s new IP address, try connecting to it via a web browser by typing the IP address followed by :5000 or :5001. If you can access the DSM login page, it indicates that your computer can communicate with the NAS. To prevent future connectivity issues, it’s highly recommended to set a static IP address for your NAS. This ensures that the NAS always has the same IP address, regardless of your router’s DHCP settings. Setting a static IP address involves configuring the NAS’s network interface with a specific IP address, subnet mask, gateway, and DNS server. In addition to IP address settings, firewall configurations can also affect NAS connectivity. Make sure that your computer’s and router’s firewalls are not blocking connections to the NAS on the necessary ports. Temporarily disabling the firewall can help you determine if it’s the cause of the issue. Subnet mask and gateway settings are also critical for network communication. Ensure that your NAS and computer are on the same subnet and that the gateway IP address on your NAS is set to your router’s IP address. If you’re using Synology’s QuickConnect service, there might be an issue with your Synology account. Try logging into your Synology account on the Synology website to make sure everything is working correctly. If you’ve tried all the basic troubleshooting steps and are still unable to connect to your NAS, it might be time for some more advanced troubleshooting. This includes checking router compatibility and firmware, looking for IP address conflicts, and, as a last resort, resetting your NAS to its factory defaults. Remember that resetting your NAS will erase all your settings, so it’s crucial to back up your data before performing a reset. Troubleshooting network connectivity issues can be challenging, but it’s important to remain patient and persistent. By following a systematic approach and trying different solutions, you can often resolve the problem and get your NAS back online. If you’re still stuck, the Synology community and support forums are great resources for help. There are many knowledgeable users and experts who can provide guidance and assistance. Ultimately, the key to success in troubleshooting network connectivity issues is to be methodical, patient, and persistent. By following the steps outlined in this guide and leveraging available resources, you can confidently tackle the problem and get your Synology NAS back up and running.
