Comment 20 for bug 293946

The fix rate method on my previous post doesn't fix the problem. The connection loses every one to two hours instead of few minutes (still an improvement, err..)

These two messages appear at the same time as the connection loses.

dmesg:
wlan0: No ProbeResp from current AP 00:19:54:2f:93:da - assume out of range

at the same time the log of router said

log message from Router:
Sat Mar 14 02:08:34 2009 Disassociated: 00-22-46-7A-EB-05 because idle 300 seconds

I google around and knows this not the problem from realtek 8187b/l only, many people with other wireless chipsets also suffer from this problem. Would anyone please help me? I am really tired with the wireless problem in UBUNTU.
Thanks!
