T-Mobile 5G21-12W-A High-Speed Internet Gateway Monitor
March 13, 2021

I recently switched Internet providers to T-Mobile Home Internet. I'm very pleased with the T-Mobile service. With my old provider I was lucky to get 10 Mbps down and 2 Mbps up. And the performance was extremely variable. Uploads were often less than 1 Mbps.

Now that I'm using the T-Mobile Home Internet service, despite living miles from a small SW Colorado town, I typically get over 100 Mbps down and over 10 Mbps up (see Ookla Speed Test Result, below). I had the good fortune to sign up right before a rate increase. I'm paying $50/month. New subscribers now pay $60/month.

The T-Mobile Device is a modem with built-in wifi router. I installed the device behind my router (a NetGear XR500), so that I can continue to take advantage of that router's features.

The T-Mobile device has an admin web app which you can find by browsing to 192.168.12.1:

The same API used by the web app can be callable by custom apps. I wrote a Python app called TrashCanMonitor that uses that API to log the values and statistics that are interesting to me. The log is a .CSV file, so the data can be easily imported into a spreadsheet:

You can get the TrashCanMonitor source code at GitHub. Enjoy!
