Ej, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.15-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Description changed: - Hi Guys, - Logging bug as requested: + 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 - - 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.
