T-Mobile's New Black Box Gateway: Faster Than Fiber?
Unboxing and testing T-Mobile’s brand new Inseego FX4100 — the smaller, sleeker replacement for the old white gateway. I upgraded because I needed port forwarding and a static IP for video production work… but what happened next with speeds blew my mind.
We go head-to-head: old gateway vs new Inseego FX4100, then I hook up my Waveform QuadPro external 5G antenna (only using 2 out of 4 ports) and… well, you need to see these results for yourself.
→ Real speed tests (stock vs with external antenna)
→ First look at the admin settings, port forwarding & configurable LAN ports
→ Why this tiny black box might change everything for T-Mobile 5G Home Internet users in 2026
If you’re on T-Mobile Home Internet and tired of the old gateway, or wondering whether a new modem + external antenna can actually deliver fiber-killing speeds, this video is for you.
Waveform QuadPro (affiliate link): https://www.waveform.com/JOE – works even on 2x2 gateways like this one!
