Hi Looking into your dmesg i see that the firmware loaded by the iwlwifi driver is version 25.15.12.0 . From this page : https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#firmware you can download the latest version, for the 3.19 kernel the 25.17.12.0.tgz is the good one. Extract it and copy it to /lib/firmware (as root) and reboot. This solve the issue for me. No more disconnection and perfectly stable.

I have now clearly identified a working and non-working version and tried to start the full commit bisect, but I am unable to follow the guide in the wiki as it points me to change the version number in the debian.master/changelog file. Unfortunately, there is no such file. Another question: The working version I identified was 3.18.6 but I can't find a tag for this version in the git repo, why is that?

[Bug 1444766] Re: Wifi connection issues
Marvin Scholz, the next step is to fully commit bisect from kernel 3.16 to 3.19 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1444766/+editstatus and add the package name in the text box next to the word Package.
