I have a wired lan connection directly from my ASUS router to my desktop computer. The connection has been fine for months. Last night I shut my desktop and turned it on normally this morning. It is no longer detecting the wired connection. No one in the house touched the router, wire, or computer at any point. The only way I can get internet is if I enable wireless. But being that the router is upstairs, the speed is slow.


I plugged the same wire into my laptop, and my laptop is detecting it fine. So now I know it's not a router or wire issue, it's my desktop. I don't understand why it would stop working out of no where. Any idea what to do?

Hi -

Please open Internet Explorer > Click Tools along the top (if you do not see it, press the ALT key) > Go Internet Options > Connections > LAN settings > Make sure the only box ticked is Automatically Detect Settings > Click OK > OK

See if there is a connection now -

 

Thank You -

OK - Last guess from me -

 

Go - Start > Right click My Computer > Properties > Hardware > Device Manager -

Look for any ( ! or ? ) marks beside anything related to internet or other items.

 

Thank You -

If the LAN is reflected in Device Manager...uninstall the driver and reboot.]

 

If there is no LAN or device requiring a driver install...your LAN chip may be dead.
