Cannot open up internet when connecting TP-Link Archer 50 to BT Openreach broadband.
I purchased an Archer AX50 dual band router to replace BT Home Hub. BT Home Hub connects to BT OpenReach white-box broadband modem straight from the phone socket. The TP-Link device connects quickly and very easily, with the WAN connection in place from the white-box openreach broadband modem to the TP LInk wifi router. All the lights come on which is great. Yet, the internet connection remains closed. I cannot figure it out and suspect that i have to somehow configure the openreach white-box modem/router to enable Archer box to gain access to the internet? Dynamic IP is enabled. Guidance please from any other BT customer. My TP-Link does not have a direct DSL connector so this is more about using the WAN extension to get wireless on TP-Line kit.
