I made a build for testing the change in comment #29, which is available at http://people.canonical.com/~sforshee/lp1293569/linux-3.13.0-26.48+lp1293569v201405121159/.
Emmanuel: I assume the dmesg need to be from a device experiencing problems? If not I can get one for you. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1293569 Title: iwlwifi-7260-8.ucode causes network disconnections problems Status in “linux-firmware” package in Ubuntu: Confirmed Status in “linux-firmware” source package in Precise: Fix Committed Status in “linux-firmware” source package in Trusty: Fix Committed Bug description: Running 14.04 (beta) with Kernel 3.13.0-17-generic I've encountered a strange and reproducible error with the iwlwifi-7260-8.ucode firmware. This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will connect fine to wifi for 30 or 40 mins at a time, then will start dropping connections repeatedly. Even modprobe -r unloading and reloading doesn't fix the issue, only a reboot will temporarily solve it for 40 mins at a time. Moreover, here is what's strange, is during these episodes of disconnection it seems to affect the actual router (2Wire), as the other devices in the house will also start to have issues (very slow connections, limited range,etc). Once I reboot this laptop everything and all devices will return to normal. This issue has been fixed by me manually removing the -8 firware from /lib/firmware and letting the -7 firmware load instead. Since that has been done there has not been a single issue of this happening (now going on 4 days). let me know if there is any other information you would like me to provide.
