DNS provider for Home Internet

Where can I change my primary and secondary DNS providers on the T-Mobile Home Internet Gateway?

You know I have had issues with trying to play online games like rocket league on Xbox and I have really high ping for no reason I even tried hooking up a router instead now it shows double NAT witch is not good for gaming I just wish independence where I live would have google FI internet we had Xfinity and they charged to much and if u went over your limit they changed 10 dollars extra I like the 50 a month and it’s added to my phone bill  but they really need to fix some of the problems 

Recently I notice my internet connections were on/off constantly. It looks like a DNS related issue.

Since I cannot change the DNS resolver in the gateway itself, I tried to change it (1.1.1.1) in my router which is connected to the gateway. So far, it looks like fix the issue.

I agree! It is not reasonable that DNS is locked down! At worse, it's a security liability for DNS leaks to maleficent actors.  At best, it is an invasion of privacy by T-Mobile. 

Unfortunately NAT level is virtually irrelevant with this service, as you are effectively dealing with the same core impact on the other side of their modem.

Their XLAT464/CGNAT/Tunnel crud just breaks a lot of things in general.

It is not reasonable that these settings are locked down. Like many other ISP's, T-Mobile almost certainly sells data (about us) collected from DNS queries. Open these settings and charge me more for the lost revenue from selling my data.

Furthermore, their DNS resolution service is surprisingly bad. We've only had their 5G internet for a few days, and we've already found several websites whose domain names simply will not resolve on their network.

It is not reasonable to essentially force me to use their modem as my firewall. We have a good number of internet connected devices via HomeKit. With our previous router, those devices were automatically segregated from the rest of the network.

Now the only way I can do that is to have double-NAT set up, which causes substantial latency and throughput bottlenecks. Their modem needs a bridge mode.

My small home does not require the complexity and expense of a second router.  I am hoping T-Mobile will allow custom DNS settings in the future.

I have a large home the can will not even cover it so I have my router/gateway plugged into the can that DNS can be changed for the whole home problem solved.

They are not going to change this soon so if you cannot think of an alt there are no other options.

I am happy as is $50 for unlimited with no data cap see my speeds attached. I can work around some of the limitations for the price and speed.

Yea over ¾ of a Gigabit down i'm happy to work with a few limitations.

This is not a good solution for a home with many devices connected to the gateway.  Most Internet Service Providers allow their customers to manage their home gateway/modem devices and configure their own DNS and other settings.

These are reasonably locked down I doubt that’s going to change anytime soon.

If this is your only issue just change in on your laptop put as many DNS providers you want 2 3 4 10 whatever just set it and done.
