[Bug 1526683] Re: rtl8821ae has no connection on 5GHz networks and loses connection occassionally on 2.4 GHz networks requiring hardware button to be toggled twice for connection to be re-established

Mikaela Suomalainen, to better scope this report, let it be focused on only the 2.4GHz issue, as two different frequency issues are treated as different problems upstream, necessitating separate reports. Despite this, could you please comment if this is reproducible on both 802.11n (300 or 150),

I just again had 2.4GHz losing connection and this message from journalctl seems related: `joulu 20 09:32:04 sedric kernel: wlp3s0: AP 30:5a:3a:68:92:70 changed bandwidth, new config is 2472 MHz, width 1 (2472/0 MHz)` I went away for a few minutes without doing anything and the connectivity had

And now I have also reproduced the random connection dropping on Linux sedric 4.4.0-040400rc5-generic #201512140221 SMP Mon Dec 14 02:23:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4

I think the kernel booted anyway with just the -image pcakgage working. Linux sedric 4.4.0-040400rc5-generic #201512140221 SMP Mon Dec 14 02:23:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux I don't have time to see if the connection is still randomly lost at the moment, but I will probably see it
