Hiye to all sifu,

Wanna ask about the current unifi connections.

My colleague recently bought this model of router. D-Link DIR-645

My question is he will be replacing it with the current router that Unifi provided, wanna know which one is the modem? The black one where the fibre cable is connected or is it the router that Unifi provided? The settings of the username and password will be set at the black or the router?

I tried to setup the router as the dialer but it seems that I am unable to make the connection available for my Unifi. When I reset and only setup the newly bought router for wireless security, it's still not able to get a connection.

Is there any compatibility issue?

Thanks!
