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?
