A couple of years ago T-Mobile 5G Home Internet finally became available in my area of Florida, enabling me to ditch longtime but miserly AT&T with their paltry "legacy" DSL (6 Mbps down / ~384 Kbps [!] up), for upwards of 170+ Mbps down / 3-6 Mbps up on 5G.
In the wake of the afterglow of comparatively fantastic speed, following hurricane Debby that blew through my area of Florida in August 2024, I experienced significantly decreased internet bandwidth with my wireless devices only.
Devices hardwired via ethernet cable, like my desktop PC, were unaffected, and speed tests for those showed around the expected bandwidth. My laptops (plural), tablets (ditto), and others though were definitely having issues. Why?
I called T-Mobile and they informed me that one 5G tower of theirs was down for repairs while at least one other was undergoing maintenance and awaiting parts. I proceeded to reach out over a dozen times by message back and forth with T-Mobile support via former Twitter and Facebook, tracking their progress and advising of changes on my end. My 5G gateway has been facing out a south-facing window of my home, and the nearest tower they recommended was E-SE, so I oriented the front face (where the 5G antennas live for this Sagemcom Fast 5688W gateway) as best I could in that general direction.
Now, here's the thing. When I first set up the gateway using the T-Life mobile app for Android, I configured it (innocently enough) with the same wifi SSID and password as that used by my TP-Link router (which supports the newer WIFI 6 standard, as does the 5G gateway). Therein lies the problem, as I found out with reasonable certainty.
The wifi 6 standard among other benefits enables you to not have to create unique SSIDs to use around your house, say. Instead of creating one SSID for say each wifi extender you might have on every compass point of your home as you might have with wifi 5 and older, now you can use a single SSID to be smartly managed by the router in a mesh setup (as I delve into here).
However, as I discovered, that does NOT mean that separate wifi 6 gateways or routers play nice, wifi wise, with each other. Computers, tablets, even wifi extenders all cope nicely within the wifi 6 standard, but "royalty" in the form of gateways and routers that actually serve as upper management for your local wifi device community can clash.
I followed steps in the T-Life app to do the following:
- From the Overview => My Wi-fi screen, create a new wifi network named TMobile (with SSID hidden).
- From under My Networks, tap the current SSID I originally configured on both my gateway and router, let's call it DARTH.
- Tap on DARTH, and on the Network Details screen, tap Delete Network, and confirm. Note also the reminder from T-Mobile, you must have at least one Wi-Fi network to be able to access the gateway from the T-Life app itself.
In retrospect, that little warning T-Mobile provides turned out to be prophetic, and I wish I took the hint early on that hey, maybe dueling wifi networks are part of the problem, here. Indeed, by setting up the T-Mobile gateway to use the exact same wifi network as my router, I can only imagine the constant radio frequency duel going on between the two devices, each with the same valid credentials and security, each vying for control of the wifi devices on my LAN.
Now, having that TMobile network on the gateway, not only hidden but completely unique to DARTH which my router manages exclusively, and the T-Life app connecting by wifi from the former network's only connected device, my phone, I now am enjoying bandwidth much like my desktop PC from my laptop.
Much better! At this point the only things stifing connectivity are what you'd expect, obstacles impeding signal between the wifi extenders and the router, the relatively elderly Intel Centrino onboard adapter this particular laptop uses, etc. Not a pitched battle between gateway and router over which one serves as the official conduit for local network traffic.
