[Bug 1421366] Re: wifi works unstable 'kernel-fixed-upstream'
While I am collecting requested information I noticed that the problem disappeared with the latest kernel update, 3.13.0-46-generic.
But anyway I updated BIOS and checked if it helps on kernel 3.13.0-41. But problem still exists i.e. BIOS update does not help considering kernel 3.13.0-41.
But now it does not matter, so we can close this bug because while we are investigating the problem it seems someone has fixed it. :-)
I cannot be 100% sure because I have not tested kernel 3.13.0-46 and old BIOS.
Now output
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Bug description:
Hello!
My wifi works unstable. It means network goes down time to time. And it makes me crazy. I am not sure where to find a cause but I found strange errors in dmesg
