[SOLVED] Wireless interface does not show up (sometimes)
Greetings!
I have recently encountered a problem with my wlan interface, sometimes it does not show up after startup.
I have Arch dualbooted with Windows 10.
I searched for the same issue, and it happens to be related to my notebook's (Thinkpad T470p) wireless card:
Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)
I have a recommended driver installed with firmware, though.
Here is the output of uname -a:
Linux t470p 4.19.61-1-lts #1 SMP Fri Jul 26 10:27:00 CEST 2019 x86_64 GNU/Linux
Name of the interface is wlp3s0. When there is no connection after startup, ifconfig shows only two devices: wired interface (enp0s31f6) and a loopback adapter (lo).
I have also found a similar issue, and it was solved by using LTS kernel. I did reinstall the kernel along with headers, but it seems to have no effect in my situation.
I am using Network Manager, and tried to use WICD, but with no result.
Any help would be highly appreciated. If you need any additional information, please let me know!

Thank you again seth for sharing this link with me, I totally forgot about disabling Fast Startup feature after Windows 10's latest update 
The problem seems to be solved for me, as there are no signs of this issue for a couple of hours.

Re: [SOLVED] Wireless interface does not show up (sometimes)
You're welcome. This is a common issue and nb. that windows has in the past shown a tendency to silently re-activate fast-startup w/ updates.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
