Your system information

• Opted into SteamOS beta?: No

Please describe your issue in as much detail as possible:

I have installed SteamOS, very easy, however while everything works, as soon as I lock the screen, the Wifi dies and never comes back unless I reboot.

I have enabled/disabled Wifi Management and WPA Supplement but nothing works. I can't find any official documentation on this specific issue.

Steps for reproducing this issue:

1. Upon boot, wifi connects, i can download games.
2. Push power button to lock screen, then unlock.
3. Wifi is now gone, no way to re-connect manually or automatically
4. Only fix is to reboot, but one the screen locks its gone again

I think similar but not sure the exact same. Code above 100% fixes the WiFi issue whereas the OS update does not it seems
