5G Wifi keeps being stopped or disconnected after around 10 minutes or when more than 70 mbps is used
You can try two workarounds. Turn off wifi power save first. Create .conf file:
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
And copy these two lines inside it:
[connection]
wifi.powersave = 2
If the issue remains, turn off Mac Randomization. Create .conf file:
sudo nano /etc/NetworkManager/conf.d/disable-random-mac.conf
Copy these two lines inside:
[device]
wifi.scan-rand-mac-address=no
Hope this can solve your problem.
