Thanks for your reply.
I used the provided small aerials at home, and a roof mounted poynting mimo aerial at the caravan. When I go back I will try using the small aerials to see if it makes a difference. I am also getting a 12v supply for the router in the car so I can see if/where it drops out between here and there.
I don’t have a screenshot from the caravan yet but I can send you the log files to you which I downloaded yesterday. How do I send them?
How do I attach the screenshots of the two sims working here at home?
