Hello. I'm getting some problems with my Atheros wireless card on my Toshiba notebook.
I can connect to my Belkin router but sometimes (maybe every 10-15 minues) my card lose the connection with the router and iwconfig says
Access Point: Not associated
When it happens I simply need to give the command
# iwconfig wlan0 essid MYESSID
(without specifying again my wep key) and it starts to work again.
It seems also that the problem doesn't happen when connection is used: if I put on background a
wget http://www.somewhere.com/something.iso --limit-rate=100
my card works without falliing asleep.
