I have a home built computer intell core 2 duo 2.93 ghz, 2gig ram with windows 7 ultimate. My nework card is a Netgear WG311T. I have been having a lilttle of a connection issue. I use my wireless card and my internet just cuts out. It is only this computer and when it happens, i look down at my task bar and it shows that i have no connection and it shows that golden which is that there is connections availible. So i think it is just unconnecting to the router by itself. This problem is random also it disconnects 3min sometimes 20 min. I have tried 3 different network cards. of which all were updated. I also installed the software with that card to see if it would help. And i use the computer at my friends and my home with two totally different routers. The card that i have use in other computer have worked,and these computers have windows XP. Im not sure what to do now it is getting very agravating. Plz inform me if you need any more information or if you have a fix TY!
