Local Area port not working

Good Morning

Iam having trouble with the LAN port, Wifi works fine

Its not picking up the port i plug into it.

No recognition, No display of Lan port(Ethernet) (Not limited,cant connect).

as if the Ethernet port does not exist.

When looking at Connection types you can see the local area connection but not connected.

I have tried.

Uninstalling drivers and reinstalling drivers, WIndows 20h2 updates,different LAN cables (Conventional and crossover as a test),Troubleshooter,Lenovo bridge update. Bios updated, Local network settings are all default no DNS or port settings, IP’s are dynamic.

There is no light to indicate Ethernet on the laptop model working or not working. No LED.

Hi @brendonmennegke,

I realize that you said that you updated the drivers (are these the ones you installed?, click on “See Files” to view the version number) for the LAN adapter but what is its status as shown in Device Manager > Network Adapters > right click on Realtek adapter entry > Properties > General tab > Device status box?

Does it state that This device is working properly?

If it shows that it is OK try resetting the Network TCP/IP stack and check

In the search box on the taskbar (click Start), type command prompt and then when the cmd app menus appear select Run as administrator and confirm.

At the command prompt enter the following commands, one at a time:

ipconfig /release and press Enter. (Yes there is a space before the / symbol in the commands that use it.)

ipconfig /flushdns and press Enter.

ipconfig /renew and press Enter.

netsh int ip reset and press Enter.

netsh winsock reset and press Enter.

When all the commands have been entered OK, close the Command window (and any other window that may be open) and restart the laptop in the normal way i.e. Start > Power > Restart and check.

Also just verifying that you checked that the Ethernet in the router is working by connecting another known working device using Ethernet to it?
