Linux ubuntu - disconnects wifi when inactive (wifi power saving)

Hi,

i have a pc with ubuntu + usb wifi module. Everything works ok, but as soon as I move away from the PC and only for a few minutes, the connection via wifi will drop out. I have to disconnect and connect and everything goes again. What I have read, so it probably causes some power saving on the wifi interface. How do I turn it off? Thanks

Hi,

try editing the default-wifi-powersave-on.conf file to wifi.powersave = 2 like this:

vim /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

[connection]
wifi.powersave = 2

Reboot
