Possible to use T-Mobile 5G Home Internet Gateway with Dual Wan setup?
Hello, I am researching T-Mobile 5G Home Internet service before committing. Currently I am using a WiFi router that supports Dual Wan setup: i.e. Cable modem + some other internet connection (i.e....

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.
This question-thread is as close to my situation as I have found.
I use an "AiMesh" network with main router an ASUS RT-AX88U and two ASUS RT-AC88s (U and W) nodes. My Primary WAN is gigabit fiber with a static IP address (that I pay $5 a month for). I have had a CenturyLink 10MBs DSL line as my Secondary WAN connected via LAN port #1 on the main router using DHCP.
I've been trying to use the Arcadyan KVD21 T-Mobile Gateway to replace the DCL modem for the Secondary WAN connection. Simply jacking the KVD21 to the ASUS using Ethernet DOES NOT WORK as the ASUS Router complains that the router/ISP doesn't correctly support DHCP. I noticed that the Secondary WAN connection advertises the IP address 192.168.12.195. I reconfigured the Secondary WAN connection from DHCP to Static IP using the "195" IP and this does work.
HOWEVER, it seems that the "195" address is transient / dynamic. I've simulated failover by physically disconnecting the primary WAN a number of times and (since I have been using the Static IP for the secondary WAN connection) it's worked OK. Last night however the Primary WAN ISP had a DNS issue so the Primary WAN connection failed and the Secondary WAN failover DID NOT WORK.
I've spoken with t-mobile support and they tell me that "third party routers are not supported" which is pure nonsense (they shouldn't even offer a service if users can't connect decent network infrastructure. My network currently has over a dozen WIRED connections and three dozen wireless clients. Some of these devices ABSOLUTELY REQUIRE various kinds of special routing configurations. A prime example is an older HP laser printer with internal JetDirect interface. ANYWAY … there HAS TO BE a way to connect the t-mobile gateway to the ASUS mesh system.
Can anyone say whether they have something truly similar to my situation working?
By the way … I've tried all my experiments with the wi-fi on the gateway enabled AND disabled. In disabled mode I can get to the user interface via a browser and 192-168-12-1 HOWEVER the browser UI has nearly no capabilities (the App (requires wi-fi @&#$&#@) has "more" (but still pathetically little).
