[Bug 1396338] Re: [Dell Latitude E7440] Wifi keeps dropping with Intel Wireless 7260
Niels Holmgaard, thank you for reporting this and helping make Ubuntu
better. Could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc6
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

-
- The frequency of the problem has dropped considerably after moving to a
- less congested channel, but it still happens - I am stationary at about
- 3 meters from the access point. Other devices (Android phones, iPad,
- other laptops) are connecting to the same access point with no problems
- at all.
-
- The problematic line in the dmesg output is
+ After the connection is dropped, a hardware switch disconnect/connect is necessary to re-establish connection, the connection does not automatically reappear. The problematic line in the dmesg output is:
wlan0: deauthenticated from 00:16:b6:01:69:74 (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
- After the connection is dropped, a hardware switch disconnect/connect is
- necessary to re-establish connection, the connection does not
