X220T ethernet port not working

2013-12-16, 1:11 AM

Hello,

 

I have updated drivers and everything and wireless internet works, but my ethernet port does not work. The lights ine port are blinking though.

 

I am guessing its a mobo issue?

 

I have tested multiple ethernet cables and laptops with my router and they all work.

 

Any suggestions?

 

Thanks. Peace.

Is the machine still under warranty?

 

Try booting a "live" Linux CD/DVD/USB stick and check whether the wired LAN works there.

 

If not, you are looking at a hardware problem.

 

Good luck.

Cheers,

George

I will look up this live linux thing and try it out.

 

Quick update. I tried to reinstall drivers. In the device manager, it shows that i have the driver installed, but theres a yellow exclamation mark. The ethernet adapter also does not show up in the list of adapters.

 

I was thinking it might be a hardware problem, but no more warranty :(

I want to make sure you know that if the machine is in a dock, you must use the Ethernet port on the dock. When docked, the port on the machine is not available.
