I was able to logon today where it asked for my network's password. It's connected now but my network has nothing to do with it.

More info: Wireless cuts on and off and is very slow.

Status changed to 'Confirmed' because the bug affects multiple users.

Changed in network-manager (Ubuntu):
status: New → Confirmed

I added an IW registration:

sudo iw reg set US

This seems to have solved many of my problems

Furthermore, I live in Brazil and after boot and when returning from hibernation "iw reg get" shows "country UZ" which is the code for Uzbekstan. Very strange!

Yesterday I uninstalled the Broadcom (bcmwl-kernel-source package) driver and since then using "open source" (brcmsmac) the wireless network no longer drop. So it seems that this confirms, at least in the case of Broadcom, that the failure is in the proprietary driver.
However, after boot and when returning from hibernation "iw reg get" still shows "country UZ"... But that is not making any difference because the wireless network showed no further failures.

I'm still experiencing this issue and it's very annoying. I was able to
compile a wireless driver but after about three weeks the problem returned.
