My wireless internet works on my laptop, phone etc.. but wired doesn't work on my pc? It worked fine yesterday?
I use windows 7 home edition I believe.

Hi
The first step is to restart the router/wireless access point

Then check there is a led on router and network card on PC to indicate that a connection has been made
check rj45 plugs at PC & router if no led

Report back if these simple checks / tests do not work

I had the same thing happen to me yesterday 3/22/2015. I tried everything like most of you all that had this problem. I just restored my system three days back and my PC is back to normal. Hope this helps!
