Description

At the OLPC Miami office it is often hard for Sugar's network view to see the desired network to connect to the first time. There are over 200+ wifi networks in the area, and each scan only finds ~20-40.

It would be nice if Sugar had a method to force all connected wireless devices that support rescanning for networks to rescan from the Network view. I keep having to run "iwconfig eth0 rescan" as root to update the list quickly (eth0 because wlan0 is renamed to that in OLPC builds, root because non-root rescans just show the last cached result).

Note this does have to be a forced rescan method that runs as root at the Linux level, even if NM takes care of that for us.

Seen in OLPC 13.1.0 os1 & prior.
