I'm also having the same issue - "6. Couldn't resolve host name" in Wayfarer.

I switched back to Ethernet for a while and it seemed to work for a bit, then put manual IP and DNS and worked on Wifi - now no longer working, and the touch env:sys/interface.prefs hasn't helped...

All I've been doing so far with MorphOS post registration is trying to install Iris and Morpheus... I can't imagine that one of those has scuppered my wifi/ ethernet connectivity, but will start rolling back if I can't find a solution.

Grateful for any support the community can offer.
