Progress report from testing your patched 3.13.0-27 build... I made it
through almost 5 days of continuous use without a disconnect. Even
though I did eventually get a disconnect, it seems to happen far less
frequently with the -8 firmware when combined with the disabled beacon
filtering.
@Seth,
This patch adds a grace period before disconnecting from the AP if we didn't
hear the beacons. This problem (not hearing beacons) was critical in our tests
in P2P Client flows, less in BSS, but still.
It avoids disconnections by giving the firmware more change to catch up on
beacons
Good.

The syslog from comment #8 shows a 2.4GHz AP:
(SSID='Math Network' freq=2462 MHz)
Both of the ones I use (without any problems so far) are 5GHz 802.11n. I
don't think I've ever used a 2.4GHz Ap with this laptop. One is an Asus
RT-N66U, the other is some

Title:
iwlwifi-7260-8.ucode causes network disconnections
Daniel: I've tested various APs in my possession on both 2.4 and 5 GHz
and don't see these problems either, so as far as I can tell it is not
related to the frequency band.
And to everyone affected, please respond to Emmanuel's requests for
information. He's the maintainer of the iwlwifi driver,

One more point - if you can increase the debug level of the supplicant, this
would be nice.
If anyone wants to try this, I have a script which might help.
I'm on a Dell XPS 13 with Ubuntu 14.04 with kernel 3.13.0-24 and I'm not

If this can help in any way (i.e. why is my laptop loading the -7 module

Emmanuel - The issue with modinfo is that IWL7260_UCODE_API_MAX is never
referenced in a MODULE_FIRMWARE() macro.

Also, there are 2 -8 firmware. One is 22.15.8.0, the other one is 22.24.8.0.
Can you please let me know which one you are using?

My wireless (XPS13 Hashwell) was basically useless as it was crashing.
Followed the advice here and switched to the -7 firmware and have had
