I don't remember since when it started but currently it seems to happen under
any load -- it does recover and manages to fetch the load but at slow speeds
and causing delayes, here is what is seen in messages:

some detail

1. kernel was built manually from dailies of intel drm team to troubleshoot a
problem I have with external dock, but I hope it is not relevant since a)
failure  seems to be coming from the firmware itself, b) I think it was working
more robustly before even with this kernel

$> uname -a
Linux hopa 4.4.0-rc1+ #1 SMP Thu Nov 19 21:18:51 EST 2015 x86_64 GNU/Linux


2. loading firmware -- updated firmware-iwlwifi recently,  not sure why
it is seeking for -17.ucode since I have only /lib/firmware/iwlwifi-7260-16.ucode
(how to fetch a version from the firmware file to see what 16.242414.0  matches?)

$> journalctl -b 0 | grep iwlwifi | head

3. iwconfig reports:

4. my wireless:

$> lspci | grep Wireless
02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)


any advice on how to mitigate this erratic behavior would be appreciated!
