For the past almost year, once in a while my wifi won't work.
At home, I use an ethernet cable. When I go out, or am out of town, about 1/3 times the wifi won't connect, and won't even find access points. Once this happens, no matter how many times I restart, the wifi won't work. The ONLY way I can get it to work again is if I reboot with the ethernet cord plugged into the laptop and into a router/switch/hub. My neighbor (the one who got me into Ubuntu) is a pretty experienced linux network admin who looked a my laptop and has no idea what is causing this. I've attached my syslog log entry for the last time this happened. Does anyone know why this is? I LOVE ubuntu but I may need to switch back to Windows because I NEED wifi to work.
Any help would be appreciated.
You will see in the logfile I tried connecting to two different APs. The one that always works is the second one, called linksys.
