Need the code for disabling wifi power mgmt in LMDE4

I need the code for disabling wifi power mgmt in LMDE4.
Initially I used the code I've been using in 19.3. That didn't work, came up with something like, "that file doesn't exist"
The commands I was using in 19.3 was;

Code: Select all

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

What are the proper commands to do this in LMDE4?

The file may not exist yet. Check if the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf exist. If not create a new file with the following line and save it as /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Code: Select all

wifi.powersave = 2
