[maemo-developers] [maemo-developers] Scanning WLAN problem

[From: kalle ahokangas]

Ok, I figured out what the problem was. I noticed that when you are scanning
as root user the behaviour is like decribed in prevous posts.
So to get the scanning work simultaneously with internet connection do not
become as root.
