Fair comment. I just assumed that everybody uses Network Manager these days. I travel with my laptop to different WiFi networks, and I never did learn any other form of WiFi setup. For the record, I do get similar drops on other networks. > I wouldn't recommend using ifconfig to enable or disable your second network > card. It is somewhat deprecated. Try using ifup and ifdown. Whilst I know that the transition has been towards using ip* over if*, I get those commands confused all the time. That's the great thing about Linux: you never know whether you're using the right tool for the job.
