It never loses signal. It does drop the connection. It sounds weird, but no other machine in the house has this problem. IT happens whether or not you use the zero config or OEM wireless app. It says signal strength is always good. Then the net gear icon flashes yellow, then green, then yellow, then green. then for some reason it goes red and I lose the connection. No one else has this problem. I'm 20 feet from the wireless router. What gives? A repair usually does the trick. It seems to happen when I'm idle for any amount of time. Then the only way I can fix it sometimes is to reboot. Others, it's to repair the connection. Could it be some kind of file corruption in windows related to DHCP? It seems like it loses the IP DNS and DG and has to be restarted to gain them to allow access to the net.
