Yep, this is what I am thinking has gone wrong. Never tried SSH'ing into one of the Hotspots, here's the results from the PING
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.000/3.333/10.000 ms
All very weird eh!!
I think I am going to download pi-star 4 on a spare MicroSD card if I can find one. No harm in trying that I guess, just may have to wait until tomorrow as I am not 100% sure I have a spare one hanging around.
