If Windows 11 shows Unidentified network on an Ethernet connection, the problem can involve the cable, router, DHCP, adapter, or network configuration.
## Method 1: Check the cable and router port
Reconnect the Ethernet cable, try another LAN port, test another cable if possible, and check for a link light on the router.
## Method 2: Restart network equipment
Restart the router according to its manufacturer’s instructions, then restart the Windows PC.
## Method 3: Run the network troubleshooter
Open Settings > System > Troubleshoot > Other troubleshooters and run the available network or Internet troubleshooter.
## Method 4: Check the Ethernet adapter
Open Settings > Network & internet > Ethernet and confirm Windows detects the connection. In Device Manager, check Network adapters for warning icons.
## Method 5: Reset network settings
Go to Settings > Network & internet > Advanced network settings > Network reset. Read the warning before confirming because network adapters and settings will be reset.
## Method 6: Check the IP configuration
Open Terminal or Command Prompt and run ipconfig. If the PC does not receive a normal local IP address, investigate DHCP, the router, or the Ethernet adapter.
### Final tip
For most home networks, automatic IP and DNS settings are appropriate. Do not use a static IP unless your network requires one.
