I'm really just wanting to know when things actually got better. Right now all I'm certain of is that 3.13 is bad and 3.15-rc3 is good. If we could narrow that down to one -rc being bad and the next one being good, or 3.14 being bad and 3.15-rc1 being good. Then I could look for commits which might be related, or worst case run a bisect between those two to find what actually solved your problem, so we can hopefully backport the fix to 3.13. It's probably also a good idea to test 3.15-rc3 or later with the -8 and -9 firmware to see if that was responsible. Unfortunately that's an awful lot to test, espeically for a problem that takes a while to show up. Hopefully the wifi-debug data will give a better idea where to look. In the mean time I'll look at the syslog you attached and see what I can learn. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1315221 Title: 8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses connection/becomes unusable on Intel 7260 Status in “linux” package in Ubuntu: Incomplete Bug description: My Intel 7260 network card regularly shows very poor performance and/or loses its connection entirely.
