Toady I just get the Boost Wi-Fi 6 modem, and has same problem when I login at 192.168.1.254, always says Invalid Username or Password.
after talking with a telus technician, fix this problem, the correct login IP is192.168.1.45, not 192.168.1.254
Its a typo, some letters are upper case and some letters are lower case.
Another way to find the ip address of the wifi 6 router or hub is to login with the NAH (Network access hub) modem , clicking on devices and select devices list tab and the ip address of the wifi 6 booster, router, hub named booster 2.
You are trying to reach the interface by using the IP address assigned by the router? For Instance 192.168.1.XX, not 192.168.1.254.
