Comment 37 for bug 374650

I have the same problem here Wifi disconnect randomly, not too often but enough to allianate the self.
Thinkap T60, 2.6.32-24-generic, fully patched, 10.04 new install. The wireless HD is "PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)".

I already changed in /etc/default/NetworkManager/nm-system-settings.conf the value of "[ifupdown] managed=false" to "true". Did somehow lessen the frequency of disconnects. Stil happens from time to time.
To reconnect I do have to turn off the Wifi switch. Turn on and an connect again but does not reconnect automatically.

I ran Debian (with KDE) for years on that machine. Never experience this issue. All other laptops are running Debian no issue.

Not downloading anything big, just a constant radio streaming.

Please Ubuntu people, any sign of hope that it will get fixed. My first experience with Ubuntu is getting disconnected!
