I wish the T-Mobile Home Internet Gateway was JUST a modem!!!

Thanks for this thread.  And I agree regarding putting the router in bridge mode.  T-Mobile, I just ordered your service, and am willing to pay you $30 a month for your device to sit here and be a backup to my primary internet.  If you don't fix this you will be getting the device right back.

Cant even port forward, this is total crap T-Mobile fix this and give the ability to put it in bridge mode.

I agree.  The problem is that the T-Mobile router is both a terrible router and a crappy access point, lacking most of the features required to set up a decent home network.  It needs to be configurable as a modem so that you can use a good router with no double nating and features like port forwarding...

I'm installing an eero 6+ mesh WiFi router with my T-Mobile Gateway.  If I use a backdoor method to turn off the WiFi radios, will I still be able to login using the T-Mobile app?  Don't you need to be connected to a T-Mobile SSID on the gateway to login with the T-Mobile app?  If not, is there a backdoor method to turn the WiFi radios back on?

It's been two years, and the brand-new Fast_5688W gateways are still locked down.

I'm still in the try-before-you-buy period — but unless I can find a workaround to disable NAT and DHCP, I may bail and tell them that provisioning with such a dumbed-down device is a deal-breaker.

Here is a PowerShell script for disabling WiFi on the 5688W, in case it's helpful.
