Correct network adapter unplugged errors
Wired Network Connectivity requires that the network cable is connected from the network adapter to the network device (such as a hub, router, or switch), the network cables are not damaged, and that the network device are powered and functioning as expected. If any of these criteria are not met, the computer may not be able to access the network.
Verifying wired connectivity
There are two methods to verify 802.1X-authenticated wired Ethernet connectivity:
- Check 802.1X-authenticated wired connectivity by using the netsh lan command
- Check wired connectivity by using the status of a local area connection
Check 802.1X-authenticated wired connectivity by using the netsh lan command
To check 802.1X-authenticated wired connectivity by using the netsh lan command:
- Click Start, and in Start Search, type cmd, and then press ENTER.
- At the Command Prompt, type netsh lan show interface.
- If the computer has connectivity, the command returns results indicating that the computer is connected, and whether 802.1X security settings are applied.
Check wired connectivity by using the status of a local area connection
To check wired connectivity by using the status of a local area connection:
- Click Start, click Control Panel, click Network and Internet.
- Click Network and Sharing Center, and then in Tasks, click Manage network connections.
- Using the local area connection for which you want to check connectivity, do one of the following:
- Double-click the local area connection icon.
- Right-click the local area connection, and then select Status.
- If the computer has connectivity, the Media State will indicate Enabled. For computers that are configure for automatic addressing, click Details. Under Property, DHCP Enabled should report YES, and Lease Obtained information should indicate the day, month, year, and time the DHCP address lease was obtained.
