Iv recently brought this device to use as WiFi in out static caravan after my original network provider box went wrong. It says it was great who ever its so slow, I can run 4g faster on my phone than I can on the box... We gave great signal, best you could probably get. I can watch anything on our firestick or any iplayer on my phone.

How do I sort this?

Disappointed in this buy at the moment sadly.
