3. There is one possible explanation to the variation in performance. The Cheapie says it's using Band20. The Peplink says it''s trying to connect using Band 3. I don't know what the phone is doing, but maybe it's using multiple bands?
I tried forcing the Peplink to use Band20, to no avail.
I've tried swapping antennae on the two routers. No difference.
The question is, why the difference between my phone (also a cheapie) and the working router? And why might the Peplink not connect at all?
