FYI, I seem to have this problem with my Dell XPS 13 (2014 Ubuntu Developer's Edition). This also has the Intel wifi chipset (Intel(R) Dual Band Wireless AC 7260, REV=0x144). I had the same error messages and very similar overall behavior.
I updated to the latest mainline kernel as suggested and I have not had a dropout since, which is probably 5 hours of active wifi over two days. Previously it was disconnecting every 5-15 minutes in a very low-traffic environment. The working mainline kernel is: 3.18.0-031800rc7-generic Previously I was having this problem with: 3.16.0-25-generic Since I am not the original reporter and I have a slightly different configuration, I am not going to update the tags/status, but I suggest he try the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396338 Title: [Dell Latitude E7440] Wifi keeps dropping with Intel Wireless 7260 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396338/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
