This is an old thread, but I wanted to post an update in case anyone else comes across a similar problem. I don't think it was interference or a heavy netowork load anymore. I think sometimes either wifi drivers or the hardware itself get in a funny state. If I remove the wifi modules and then modprobe them again WiFi starts working great. Whenever I have network problems at the UMN now I sudo su to root, then run: rmmod iwldvm iwlwifi; sleep 1; modprobe iwlwifi As soon as I reconnect I can use the internet as expected. I think it has something to do with suspend. When I close my laptop it suspends. When it wakes up, there's about a 75% chance that I'll have to do the rmmod/modprobe thing to get connected again. -- Michael Moore On Tue, Sep 3, 2013 at 7:30 PM, Michael Moore <stuporglue at gmail.com> wrote: > Hello all, > > I installed Debian over the summer, replacing a Ubuntu install and now > that I'm back at school can't get on the Wifi under Linux.
