I just received the T-Mobil 5G Gateway G4AR-1 and Access Point as part of the Home Network Plus package and am getting phenominal speeds (750 down, 125 up).  On the back of the router there is an IP address and admin and admin password.  However when you put the IP address in it comes up to absolutely garbage stuff with no access to any settings.  It tells you to download the “T-Life” app, which also gives you no access to settings.

I guess my question is, can the SSID and/or factory password be changed somehow?
