Hey Gene, Yeah, SPI might have been an idea, I kinda liked the idea of a controller box over ethernet.
Anyway, the recommended USB adaptor has been ordered, hopefully this solves my problem, the issue is probably not the WiFi connection as such but the oddball routing though the wifi to ethernet gateway made from an old router ...
