So i got a new desktop With windows 7 and i was trying to hook it up with my Linksys WRT160N router via wires , it worked but connection kept getting dropped. I upgraded firmware and it was working fine. After few hours it stopped so unplugged my router and plugged it back and well it doesnt work at all now. I try to go to the router page by typeing the IP of it in the browser and it doesnt even come up, i also get errors like Local Area Connection does not have a valid IP Configuration. I tried a older DLINK router and the same thing is happening.
