I've tried quite a few of the suggestions there but there are some that look promising.
I agree. It worked fine before, and then stopped but I doubt if anyone else would have known how to do it. The main password is available to anyone who has access to the safe, where the plastic bit normally at the side of BT modems with this information is kept. Only a few of us have a key though no one in the Judo club is included. But I am the only one with any level of knowledge about IT.
If I understand correctly the problem is with both extenders. I would start with checking the settings of the router. Unless changing a setting on one extender also changes the setting for the second extender, I can't see how both extenders would have had the same setting changed.
That tells me that the problem has to be with the router at the church. Can you temporarily use another router to test if you can access the net?
I agree but why does the router allow WiFi access within the church but not in the adjacent halls. It is used every Sunday to live stream the service.
