Encountering the dreaded ‘Unidentified Network, No Internet’ error on your Windows computer can be incredibly frustrating. It means your device is connected to a network, but you can’t access the internet. This problem can stem from various sources, ranging from simple configuration glitches to more complex hardware or driver issues. This comprehensive guide will walk you through various troubleshooting steps, starting with the easiest and most common solutions, and progressing to more advanced techniques. By systematically addressing potential causes, you’ll increase your chances of restoring your internet connection and resolving the ‘Unidentified Network, No Internet’ error.
## Understanding the ‘Unidentified Network, No Internet’ Error
Before diving into the solutions, it’s helpful to understand what this error message actually means. When your computer connects to a network, it goes through a process of identifying the network and obtaining an IP address and other network settings. The ‘Unidentified Network’ part of the message indicates that your computer couldn’t properly identify the network it’s connected to, which usually means it couldn’t get an IP address from the network’s DHCP server (typically your router). The ‘No Internet’ part confirms that your computer can’t access the wider internet through that network connection.
## Preliminary Checks and Simple Solutions
Before getting into more technical troubleshooting, let’s start with some quick and easy checks that often resolve the issue:
1. **Check Your Physical Connections:**
* **Ethernet Cable:** If you’re using a wired connection, ensure the Ethernet cable is securely plugged into both your computer and your router or modem. Try unplugging and plugging it back in on both ends. Also, inspect the cable for any visible damage like kinks, cuts, or frayed wires. If you suspect the cable is faulty, try using a different Ethernet cable.
* **Wireless Connection:** If you’re using Wi-Fi, make sure you’re connected to the correct Wi-Fi network. Double-check that you’ve entered the correct password. Try disconnecting and reconnecting to the Wi-Fi network.
2. **Restart Your Modem and Router:**
This is often the first and most effective solution. Your modem and router are the gateways to your internet connection, and restarting them can often clear temporary glitches.
* Unplug the power cords from both your modem and your router.
* Wait for at least 30 seconds. This allows the devices to fully discharge and reset.
* Plug the modem back in first and wait for it to power on completely. This usually takes a minute or two, and you’ll know it’s ready when the indicator lights stabilize.
* Plug the router back in and wait for it to power on completely. This may also take a minute or two.
* Once both devices are fully powered on, check if your computer can now connect to the internet.
3. **Restart Your Computer:**
Restarting your computer can resolve temporary software glitches that might be interfering with your network connection.
* Simply restart your computer through the Start menu.
* After the computer restarts, check if the ‘Unidentified Network, No Internet’ error is gone.
4. **Check Airplane Mode:**
It sounds simple, but sometimes Airplane Mode can be accidentally enabled, disabling all wireless connections.
* In Windows 10/11, search for “Airplane mode” in the Start menu.
* Make sure Airplane mode is turned **off**.
## Advanced Troubleshooting Steps
If the preliminary checks didn’t solve the problem, move on to these more advanced troubleshooting steps.
5. **Release and Renew Your IP Address:**
Your computer obtains its IP address from your router’s DHCP server. Sometimes, the IP address can become invalid or conflicted, leading to the ‘Unidentified Network’ error. Releasing and renewing your IP address forces your computer to request a new IP address from the router.
* Open Command Prompt as an administrator. Search for “cmd” in the Start menu, right-click on “Command Prompt,” and select “Run as administrator.”
* In the Command Prompt window, type the following commands, pressing Enter after each one:
ipconfig /release
ipconfig /renew
* The `ipconfig /release` command releases your current IP address.
* The `ipconfig /renew` command requests a new IP address from the DHCP server.
* After running these commands, close the Command Prompt and check if the internet connection is restored.
6. **Flush DNS Cache:**
The DNS cache stores the IP addresses of websites you’ve visited. Sometimes, this cache can become corrupted, leading to connection problems. Flushing the DNS cache clears this stored information and forces your computer to look up the latest IP addresses.
* Open Command Prompt as an administrator (as described above).
* In the Command Prompt window, type the following command and press Enter:
ipconfig /flushdns
* You should see a message confirming that the DNS Resolver Cache was successfully flushed.
* Close the Command Prompt and check if the internet connection is restored.
7. **Reset TCP/IP:**
TCP/IP is the set of protocols that your computer uses to communicate over the internet. Resetting TCP/IP can resolve configuration issues that might be causing the ‘Unidentified Network’ error.
* Open Command Prompt as an administrator (as described above).
* In the Command Prompt window, type the following command and press Enter:
netsh int ip reset
* **Important:** After running this command, you **must** restart your computer for the changes to take effect. You’ll likely be prompted to restart in the command prompt window itself.
* After restarting, check if the internet connection is restored.
8. **Check Your Network Adapter Driver:**
An outdated, corrupted, or incompatible network adapter driver can cause network connection problems. You can update or reinstall the driver to resolve these issues.
* Open Device Manager. Search for “Device Manager” in the Start menu.

* Locate your network adapter (it will likely have a name like “Ethernet Adapter” or “Wireless Network Adapter”).
* **Update Driver:** Right-click on your network adapter and select “Update driver.”
* Choose “Search automatically for drivers.” Windows will search for and install the latest driver if one is available.
* **Uninstall and Reinstall Driver:** If updating the driver doesn’t work, try uninstalling and reinstalling it.
* Right-click on your network adapter and select “Uninstall device.”
* Confirm the uninstallation.
* Restart your computer. Windows will automatically reinstall the network adapter driver upon restarting. If it doesn’t, go back to Device Manager, right-click on any device, and select “Scan for hardware changes.”
9. **Check Your Firewall Settings:**
Your firewall protects your computer from unauthorized access, but sometimes it can incorrectly block network connections. Check your firewall settings to ensure that it’s not blocking your internet connection.
* Open Windows Defender Firewall. Search for “firewall” in the Start menu and select “Windows Defender Firewall.”
* Click on “Allow an app or feature through Windows Defender Firewall.” This will open a list of installed applications and features.
* Make sure that “Network Discovery” and “Network and Sharing Center” are checked for both “Private” and “Public” networks. If they are not, check the boxes and click “OK.”
* If you are using a third-party firewall, check its settings to ensure that it is not blocking your internet connection.
10. **Disable and Re-enable Your Network Adapter:**
Disabling and re-enabling your network adapter can sometimes resolve temporary communication glitches.
