Hi Janui,
The wifi profile is saved, and it will work after a reboot. Unfortunately the connect button will only work after Rune has been booted with its Access Point disabled. In the current release Access Point is enabled by default. This has already been changed, but will only be effective from the next release.
Enabling the Access Point by default has caused problems for me, as I now can't switch it off - the AP stays active irrespective of my attempts to deactivate it, and the AP is still visible in my wi-fi analyser's channel graph. I'm on 0.5b, build janui-20180903-8 - the problem is present on both my Pi 3B and my 3B+. In previous versions of v0.5b I had been able to switch off both the AP and wi-fi via the UI correctly.
For the record I use wired ethernet for all my Runes, and I prefer to keep the Pi's radios switched off in order to minimise crowding on my local wi-fi bands.
Will this be fixed in the next update?
Thanks in advance,
Peace and friendship,
