So if I understand you, you have now gotten your T-Mobile 5G gateway, shut off its wi-fi (double NAT), and successfully setup your Asus router for dual-wan with T-Mobile primary and Xfinity secondary. If so, have you tested the function by disconnecting T-Mobile, detecting failover to Xfinity, and then reconnecting T-Mobile to confirm fallback to T-Mobile? Are there any "tricks" to this setup? Gracias.
Yes, that's correct. WiFi is turned off on T-Mobile Gateway + it's connected to Asus RT-AX86U 2.5G port, Motorola cable modem for XFinity is connected to ASUS router Wan port. In Dual WAN setup T-Mobile is selected as main Wan, Xfinity as fail-over + fallback checkbox selected (using 5sec ping to google as connection check). When I disconnect T-Mobile Gateway form Asus router XFinity cable kicks in within 10sec, connecting T-Mobile Gateway back makes Asus to fallback to T-Mobile within 10sec.
Auto fail-over is another reason to do this if you have an internet connection you need to always be on such as for a home security system, dual-wan can use an ip address on cable, dsl, or cell as the second "backup" connection in that mode. Any should work.
