I also have this problem. I use a TPLINK TL-WN620G+ wireless card(USB). I can't find an official linux driver so I use the ndiswrapper. It can work. But It can't work after the access point(wireless router) reboot. When reconnect, it always ask for password(the password no change) then can't connect any more. from the log:
NetworkManager: <info> (wlan0): supplicant connection state: associated -> disconnected NetworkManager: <info> (wlan0): link timed out. Any thought about this issue, driver? 2009/6/23 Bill Moseley <[email protected]> > On Mon, Jun 15, 2009 at 11:37:39AM +0200, Alexander Sack wrote: > > > > Hi, > > > > On Sun, Jun 14, 2009 at 07:37:49AM -0700, Bill Moseley wrote: > > > I recently upgraded from Ubuntu 8.10 to 9.04 a Thinkpad with an > > > Atheros AR5418 using the ath9k module. > > > > Could you please check if more recent drivers help you?
