I found the following post How to CHANGE wifi connection?

Looks like that does the trick, so my plan was as follows:

  1. put SD-card in my laptop
  2. find the configfile, something like “ /hassos-overlay/etc/NetworkManager/system-connections/my-network”
  3. change the contents to suit the SSID that I want.
