I was going to submit a new bug with my Carbon X3, but it says linux- image-3.19.0-12-generic is not an official package. I'll try again after a reboot with the new kernel.
Anyway, my symptoms differ. I can get it back with a disable/re-enable. I've noticed download speeds seem to vary dramatically, sometimes connection to a website is lost and regained causing the page to timeout temporarily, etc. This started to occur after I upgraded to 15.04. It did not occur previously. I did this to get all the mouse buttons working properly, which they do, but something between the two really messed with wireless dependability. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437913 Title: 8086:095b [Lenovo ThinkPad X250] Wifi unstable on vivid with Intel 7265 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1437913/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
