T mobile tech support is just incredible

Had a hysterical / dreadful call with TMobile 'technical support' today trying to verify the simple question of 'how do i turn off the WifI signal the gateway generates (you can't)'. Support was 24/7, but isn't. It's meant to start per TMobile's help line at 6am Eastern, but wasn't at 6.20am Eastern. 
 

But then the fun comes when you get someone. There are a few fundamental issues:​​​​​ For both the folks i spoke to, English wasn't their first language. I think Networking wasn't a language they knew at all.

I described my set up with an Xfininty cable Gateway as my primary WAN ethernet source and using the TMobile 4G/5G (Arcadyan) gateway as my failover WAN source via ethernet. Both devices go into my router/FW and then onto my Wireless APs. I asked how/if i could turn off the WiFi signal being generated by the TMobile Gateway.

The first person kept asking me about my extenders? I have no idea if they meant Wireless Ap extenders, but i think they were just meaning the ethernet cables going to my router. The second person seemed to have better english, but again teh suggestions were just funny.

• TMobile's first suggestion to turn off the WiFi was to turn off the gateway entirely. This would work in defeating the wifi, but of course would stop any form of WAN being delivered from TMobile. 
• 2nd suggestion was to get a 4G local cell point which would take my Xfinity signal and create a WAN signal from that (what’s the point? as that already exists, and would be no failover)

Overall i think the issue is That TMobile has chosen to no longer allow users to control the WiFi generated in their own homes, which is atrocious behavior. I switched to TMobile from AT&T a decade back because TMobile had great customer service, but it seems those days have gone.

it would be nice to find someone at TMobile tech support who understands networking also :) It sure ain’t the tech support line.
