Hi Emmanuel.

Original submitter here:

Unfortunately I haven't had time to try to capture packets during
failure, but I'm open to doing that (hopefully today or tomorrow).

Here are the details for my AP:

Overview: 		This is one of the standard ATT Uverse Modems. No specific config changes (besides password), otherwise stock standard. 
Manufacturer:		Pace Plc
Model:			3800HGV-B 
Software Version:	6.9.1.42-plus.tm
Wireless Mode:	802.11b/g
Auth Type:		WPA-PSK (TKIP) and WPA2-PSK (AES)
DTIM Period:		1

Others in thread who are affected, please post an overview of your AP so
that a profile can be built.

Regards,
Barry

  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.
