I have used RRC successfully via iphone and other mi/fi devices for over a year. Following a few months away from using the system, I find that the RRC will not connect with the iphone 7 hotspot, or any other mobile cellnet device for that matter. I should say that the iphone does report that it is connected, however, the RRC green power light remains flashing and will not lock on. The RRC connects as normal to my home wifi. Can anybody help? I've seen some other posts relating to iphone connections but they don't really resolve my problem.
