Accessing wireless network usually works fine on my Ubuntu 10.10 on Lenovo T400. But sometimes,
Lost wireless connection after the OS having been on almost a week:
When it happens like today, I cannot connect to a wireless network, although Network Manager can detect and show all available wireless networks. It is also strange that WICD cannot detect any available wireless networks either.
Lost wireless connection every few minutes:
When this happens, the wireless network connection became lost after a few minutes. After manually trying to reconnect, it was able to connect again, although it got lost again after another few minutes.
My system has been up for almost a week, and there have been various programs running including Firefox, Google Chrome, and HTTrack. Not sure these can be factors of the problem.
I was wondering why the problem happens and what I can try to solve the problem?
Thanks and regards!
