Where to find new firmware

That’s the latest “firmware” .0143

At least it was on Jan 2021 when I asked, I was also told or under the impression that new releases are automatically pushed to the device but doesn’t hurt to keep up to date on that.

Tmobile is very good and impressive with their Home Internet support line, you don’t even have to be put on hold, you can enter your phone number for a call back when it’s your turn, it works very well.

It works so well that I think you are better off doing the call back vs. waiting on hold.
