How can I add wifi? (Joggler and Squeezeplay on Ubuntu 18.04)

Hi All,

I've got a Joggler all set up and working well, when plugged into the LAN.

I want to remove the LAN cable and use Wifi. How can I add the wifi name and password?

I'm using Ubuntu 18.04 (https://birdslikewires.net/debian-for-openframe), on the internal drive (https://birdslikewires.net/openframe-flash) and installed Squeezeplay with the sudo of-install squeezeplay command.

On the ...
https://birdslikewires.net/debian-for-openframe
... page, there's a method for adding wifi details as party of the install process, but only when it's installed on an external drive.

How can I add the wifi details when it's on the internal drive (and installed via the OpenFrame-Flash)?

I could install it all again if needed, but I'd prefer to add the Wifi details to the working system, if possible.

Can anyone help,
Thanks.
