Public bug reported:

Hi Guys,
Logging bug as requested:

I believe related to Intel driver / firmware - iwfwifi-7260-7.ucode
and/or iwfwifi-7260-8.ucode

Original post from
"https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305305";

"I have the same issues as descibed above with brand new Intel 7260ac
card.

Dell E4300 laptop - (4GB/Samsung evo 250gb) on Ubuntu 14.04 3.13.0-24-generic
Intel Driver version - 22.24.8.0 (this is shown when running "dmesg | grep iwl" in terminal)

Fresh install of Linux and all updates installed - this issue occured on the prior installation of Ubuntu as well.
Will work connect perfectly on boot and works fine for 10mins - a few hours then it drops out and won't reconnect until system is put in standby (shut lid to standby) and then power back up (open lid to power back up) - then wifi connects and runs fine.

I too get the varying signal strength issue - not physically moving
laptop at all and signal will jump from 4 bars to 1 then after a while
it jumps back to 4 bars again. Laptop is only 4-5 meters away from WiFi
router but through one heavy brick wall.

I have tried upping the output of the router (Linksys w/ DD-WRT) from
100 mw to 120 then 140 but this made the connection worse (noise to
signal was awful). Once router reset back to default at 100mw it
returned to the same as prior.

Apologies for the wall of text. :)

Kind regards,
Ej."

Apologies in advance if I have missed any important details, if so I'm
happy to help.  :)

I have dropped the beacon interval as advised and am testing to see how it goes. 
Additionally, if I change router settings and the laptop drops the connection (as it might depending on setting changed), sometimes it will reconnect automatically, sometimes not.  If the system is put in standby for a few seconds and woken (as descibed above) it will pick the connection back up every time.

If I can provide any other information or perform testing, please
advise.

Thanks again,

Ej.
