This BIOS update came out literally one hour after I reported the bug, I updated on the same day with no effect on the bug.
As you see: root@XPS12-9Q33:~# dmidecode -s bios-version && dmidecode -s bios-release-date A07 11/17/2014 The bug stays the same - after a grace period of a few minutes up to an hour or so, the connection drops, subsequent connection attempts are met with failure as outlined in the original report and documented by dmesg log. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1413694 Title: Since 3.18.x, iwlwifi has severe connection problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1413694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
