Title:
8086:08b1 (rev 73) [Dell Latitude E4300] Stability of Intel 7260ac
mini wifi card
Status in “linux” package in Ubuntu:
Expired
Bug description:
Fresh install of Linux and all updates installed. This issue occured on the
prior installation of Ubuntu as well (what version specifically???).
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.
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.
I have dropped the beacon interval as advised and am testing to see
how it goes.
I believe related to Intel driver / firmware - iwfwifi-7260-7.ucode
and/or iwfwifi-7260-8.ucode
