Comment 105 for bug 414560

There are a number of bug reports for NM already. You can start with this

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/291760

and the subsequent Gnome bug report

https://bugzilla.gnome.org/show_bug.cgi?id=580185

I provided a patch to remove the offending background scanning behavior in NM (the patch is attached to both of those bug reports) but the NM guys still believe that background scanning is a Good Thing (never mind the problems it causes, and never mind that other tools like wicd that don't do background scanning work perfectly).

The Gnome NetworkManager bug list also has several bug reports related to this scanning behavior, some people complaining that it doesn't scan fast enough,

some complaining that it scans too much.

Personally I think this feature is an exercise in futility, and they really need to dump it and just go with manually invoked scanning.

But at this point, having sent numerous emails and samples of perfectly good code to them and being ignored,

I don't have much hope that they're ever going to see the light. Look at their bug list

https://bugzilla.gnome.org/buglist.cgi?quicksearch=product%3A"NetworkManager"+

it's got over 300 open bugs stretching back more than 3 years and they just ignore them.
