Hello,

I use the system with Apple AirPort Extreme. The same hardware is
working reliably under Win XP.

With Ubuntu, my wireless connection drops almost every day. It happens
at random times and I cannot pinpoint what's causing the problem.
Usually I find it disconnected when I unlock my desktop after at least
several hours of inactivity. It is much more seldom to see connection
dropping while I am using the laptop but I believe I saw it once or
twice over a 5-month period.

Usually I am able to re-connect either by disabling and re-enabling
networking or by a restart of the system. Sometimes it takes two
consecutive restarts to get connected.

My wireless network is always visible in the list but when the problem
occurs I get a prompt for a network passphrase, sometimes for several
times. I even tried to re-type the passphrase but it doesn't help.

I have several other laptops (Mac and WinXP) that work fine and do not
exhibit the same problem. Since I installed Ubuntu on a different hard
drive (this is the only change from WinXP days), I can boot from the old
Win XP drive and wireless works fine that way.

A Partial dmesg output (full available) after the system was restarted
yesterday and I did not even log into it until today's morning. Found
wireless disconnected; disabled networking through UI; re-enabled it
back; finally got connected to the network.

I should also note that connection not always drops when computer is
idle. I can have it running for two days without actually touching it
and then find network being fine when I unlock the desktop.

The computer always stays on. It is not configured to go to standby or
sleep mode.
