I have two computers wired (not crossover cable) through LAN router (Huawei HG510) and one computer connects to internet through wireless card (NETGear WG311). When I turn on LAN my wireless is connected but no internet. I was sharing internet with ccproxy but now proxy is not working because of LAN. It works for a while and then stops. I tried configuring gateway and orger of networks in networks connections (advance properties or smthing) and my lan and wireless worked but now is is not working again. I shared internet with proxy 5 days ago and it worked, but now it stopped. I don't know what is the problem... In linux it works just fine.. Someone help me ?
