Persistent wifi pass

My netvn is not tagged as disposable and is using debian template, however I have to manually enter a password each time for my wifi.

How do we force wifi password to save ?

In your Network-Manager setting:
Network-Manager > Edit Connections > Wi-FI: YOUR_SSID > Wi-Fi tab

In the Device field you might have wls6 or wls7 value (or else).
Delete it and leave the field empty.
Optionaly, instead of empty value, you could use your MAC address only (e.g. 3C:97:0E:42:1A:19).
Save and close the Network-Manager setting.

Perfect thx!
