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

" have a double NAT situation and the T-Mobile gateway is emitting frequencies that are going unused. This is a huge oversight on T-Mobile’s end. "

The problem, as I understand it, is in Carrier-Grade NAT, the protocol used by T-Mobile and some other companies.

The public IP address you get is the broadcast tower, not your device as in other forms of Internet such as cable or DSL, and it communicates with your device through a TCP/IP port. 

That way, they can make best use of the limited IPv4 addresses in their netblock. If T-Mobile switched to IPv6 at the tower, we could get a fully-capable — and bridgeable — gateway because every subscriber would get their own IP address.

That's as I understand the conundrum.

There are third-party gateways out there which are authenticated on your network via your simcard and are bridgeable, but they're hella-expensive.

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.

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?

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...

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

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.

You can turn off the Wi-Fi by any of these methods.  However, the Gateway is still a router.  I have found no way to operate it in Bridge Mode.  Therefore, I still have the double NAT issue and cannot access my home network remotely via VPN.  T-Mobile, please provide just a 5G modem with out a router or give the ability to operate the Gateway in bridge mode!

Yes, use your T-Mobile Internet app to add/delete SSIDs. 

On the Home Screen, tap the “NETWORK” link at the bottom of the screen > tap on the existing SSID to edit or delete it. Tap the + at the bottom of the screen to add an SSID.

Wow!! Thank you soo much for helping me understand this. Now, how do I turn off T-Mobiles’s SSID? 
 

I’ve seen a bunch of YouTube’rs hacking the T’s Gateway! I don’t think I have the patience right now to start tearing apart the box lol just funny how there’s always someone who will bust open an issue that these service providers try to block us from getting the best bang for our buck! lol 

I know how to log into my T-M’s Gateway Admin can I turn off the SSID in there? 
 

@Cyberfunkjy you and I have a similar setup so you would benefit from disabling the SSIDs on your T-Mobile gateway.

As for streaming Netflix and alike from your TV, you should setup your TV to use the SSID of your Eero. For example, if your home SSID is “Cyberfunky” on the Eeero, then the TV should be using the same Cyberfunky SSID. The TV doesn’t care if you have T-Mobile internet, Verizon, or Comcast - internet is internet. 

Your TV setup would look like this: TV > Eero > T-Mobile gateway.
