[Bug 291760] Re: network-manager roams to (none) ((none)) - background scanning

[Nthalk]

This is NOT a driver issue.

This issue is a result of NetworkManager expecting wireless drivers to be
able to bgscan and be connected/responsive at the same time.

It is not a driver issue because there's probably nothing WRONG with the
driver other than NetworkManager's false expectations of what it can do.

Is there some RFC I do not know about that involves bgscans to not interrupt
or interfere with current connections? How much do the first 2 letters of
bgscan actually promise?

The solution to this bug is and has always been to include a simple setting
for enabling bgscans.
We had a patch for this behavior a while ago, but some developer shot it
down screaming something about "NM is not broken, your drivers are." Sure,
my drivers are not that great, but I do not have many options, and it's a
lot easier to write an if statement and settings panel than it is to write a
wireless driver.

This seems like a simple fix, and it's affected 3 of my (different) laptops
so far. End user options are to use WICD, roll their own patched NM without
updates, do it cmdline/conf files, or run Windows / Mac.

I chose WICD.
