Any suggestions? More diagnostics is needed to make sensible suggestions. A couple of things to look at next time you have a network outage: * check the logs - mainly : /var/log/kern.log and /var/log/daemon.log. There might be interesting stuff in /var/log/daemon.log too. Messages with a timestamp immediately you lose the network connection may give clues to what is going on. * Do you lose association with the access point? (iwconfig wlan0 and studying /var/log/kern.log for wlan0-related messages will give the answer to this) * Is the network interface still up? (ifconfig wlan0) Has it got the right IP address? /var/log/daemon.log will show dhcp-related events here... * Can you reach the access point with ping? Hope this helps -- Karl E.

It is very bad form to do so without permission. Having said that: the advice has little to recommend it. A live CD working and your system not says more about about your system rather than its hardware (about which we know nothing). -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
