AC1200 Dual-Band USB 3.0 Wifi Adapter

[leona]

Hi
I'm using Mint 18.3
I have the above adaptor
I've get the drivers from github
the adaptor starts up ok
but after a period of inactivity it seems to loose internet access, the status shows online, but can't access websites or emails.
Unplugging and reinserting the adaptor seems to fix the problem.
This problem only seems to happen on my partners account, rather than mine.
This didn't happen with a previous adaptor, so this must be the cause?
Any idea how I can diagnose and fix this? It annoys my partner and causes me grief, so would like to resolve it.
Thanks
Leona.

I would disable Network Managers ability to enable wifi power management with

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service

[leona]

Oh nice idea, ya that makes sense, thank you will give that a try.

[leona]

Marking as solved as haven't seen the problem since, thank you.

[leona]

Spoke too soon, not solved, it died on my tonight, lists all the networks, but will not connect to any of them, have to pull the adaptor and reinsert, only seems to do this if computer on for some time.
Have updated to Mint 19.1 since I posted this.
