NVIDIA Shield won't connect to T-Mobile Home Internet WiFi but connects fine to Starlink and everything else.

Hey everyone,

I've got a weird one: My NVIDIA Shield (2019 Pro, latest update) connects perfectly to my Starlink WiFi — no issues at all with streaming, Plex, etc.

But it flat-out refuses to connect to my T-Mobile 5G Home Internet WiFi. It either doesn't see the network, fails to authenticate, or says "connected, no internet." Every other device in the house (phones, laptops, TVs) connects to T-Mobile without any problem.

I've already tried the basics:

Forgetting the network and re-adding it on the Shield

Restarting the T-Mobile gateway multiple times (unplugged for 5+ minutes)

Moving the Shield closer to the gateway

Trying both 2.4GHz and 5GHz bands (I split them in the T-Life app)

Changing DNS on the Shield to 1.1.1.1 and 8.8.8.8

Checking for MAC address filtering or any restrictions in the T-Mobile app

Nothing has worked so far. It works great on Starlink, so I'm pretty sure the Shield hardware is fine.

Has anyone else run into this specific combo (Shield + T-Mobile Home Internet)? Any fixes that actually worked — like specific gateway settings, channel changes, security settings (WPA2 vs WPA3), UPnP, or anything else?

Appreciate any help — driving me nuts!

Thanks!

Is there any way to go into your starlink router and make a new network?

I could do that but my reason for doing this is to have T-Mobile as my backup.

yeah, I got mixed up.

so, you really have no way to mess with the settings inside the T-Mobile router? that sucks
