I have a client using a Pepwave Max BR1. Their internet connection is a 3rd party Wifi antenna connected to the WAN port and the Max BR1 is then connected to a Unifi network switch. They were reporting slow internet, I investigated and connected the antenna directly to the network switch to see how it performed and we were getting normal bandwidth. If I put another router in between I get normal speeds however when connecting the Pepwave directly back to slow speed.
As everything works normally when the Pepwave is not directly connected I am confused, any suggestions gratefully received!
