Hi, I have the same problem as you guys, except I have a netgear
wireless card and a netgear (semi-new) router. I noticed that whenever
my computer wasn't actively connecting to the internet, after a while,
the connection would just drop. Same thing when it comes out of standby.
It will just sit there, disconnected until I manually "Diagnose and
Repair" which takes at least a minute, or release and renew IP, which
takes just under a minute. It's totally infuriating, as I have to do
this like 3 times a day.
Has anyone noticed the problem and is using netgear hardware?
