Hi there, im using unifi for 1 year+ last last night my dlink tm wireless router spoilt. So i bought another tp-link TD-W8961ND for it, the seller told me this can support unifi. I tried to connect only the tplink and go in modem access to configure everything but it seems cant work.

BTU internet light blinking, other all ok
Wireless router WAN, LAN1 ok, but DSL and internet no light

I read through the guide at klseet for w8960ND but cant get it work too, the modem configuration page is totally different with mine, btw my firmware version is 1.0.0 build 100722 Rel 05210

How can i configure it so it can connect the BTU? Anyone can provide me a step by step guide?
