I'm trying to upgrade my router from a BT Home Hub 5 to Asus RT-AX82U for greater range and power. The Asus is connected to a Draytek Vigor 130 modem. Windows 10 Pro can see the router but I can't get an Internet connection. My ISP is BT. I've been told that the problem is likely to concern a password needed between the modem and the ISP. Can anyone help?
