Hi all, I installed a Dahua system with N52B3P4 nvr and all worked fine with my lousy dsl thats only available on my road. Recently I added a T-Mobile WiFi cell tower. Of course my system couldn't be found so I ordered a dongle and tried to connect it wirelessly. I tried but the nvr did not see the dongle so I ran Ethernet line to the T-Mobile tower but I still can't see my cameras. What am I doing wrong? TIA
