I have fiber internet / router in Building A . I have a TP-Link AC1200 wifi router in Building B which connects wirelessly to building A and works fine. If I connect a laptop to the LAN port of the AC1200 I have a good internet connection. Between building B and C, I have Ubiquiti Nanostations creating a wireless bridge. If I connect a laptop to the wireless bridge in Building C, I do not get an internet connection. For testing, I have a TMobile cellular internet router that I can connect to the wireless Bridge in Building B and then the internet works like it should in Building C. Can anyone explain why the wireless bridge works fine when I connect it to LAN port on the TMobile router, but does not work when I connect it to the LAN port on the AC1200 router. Thanks!
