If anyone wants to try this, I have a script which might help. It can be downloaded from http://people.canonical.com/~sforshee/wifi-debug. After downloading you need to do the following in a terminal after changing to the directory where you donwloaded the file: sudo apt-get install iw tshark chmod +x wifi-debug sudo ./wifi-debug -p Wait for the problem to occur, then press Ctrl-C and wait for the script to finish. After it completes you will have a file named wifi-debug-files.tar.gz with the requested data. Note that this file will be large (potentially very large if it runs for a long time) and may contain some private information, though WPA/WEP keys should not be present and data sent on an encrypted network will be encrypted. However you still may want to share the file in a less public way, e.g. upload it to dropbox or similar and send Emmanuel or me a link. And if anyone has the know-how to capture a sniff using a monitor interface on a separate machine, that would be preferable to the method used in the script. Thanks! > Also, there are 2 -8 firmware.

Emmanuel: The firmware version in our linux-firmware package is 22.24.8.0. -- 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 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.
