Have a new astrobox set up on a RasPi using the recomended wifi dongle. Everytime I go to change the wifi settings, I can scan for networks, select my network and enter a password. After waiting patiently, it informs me that settings could not be saved. I am able to connect to my box both LAN and through its hotspot.
The network i'm connecting to is 2.4g, works with numerous other devices. Printer is a Rep2, but that should not be a factor here.
