T-Mobile Home Internet Users See What Can Happen with a Bad Firmware Update

When it comes to updates or upgrades, it may be a good rule of thumb to say that, “if it’s not broke, don’t fix it.” However, with concerns around security, it’s a good idea to keep your electronic hardware up to date when security patches are made available. 

This is something that tens of thousands of T-Mobile home internet users have encountered as of last week. Due to a software update, users reported their service had stopped working. The reason not all of their 1.5 million users (as of Dec 2022) were affected was because the update was only sent to a certain model modem – Sagemcom Fast 5688W.

The problem caused the modems to be cut off from the carrier’s network. This then prevented them from being reset from T-Mobile’s end, according to the Mobile Report. What makes matters worse, is that customers’ only solution is to swap out the modem for a completely new unit. 

Not surprisingly, T-Mobile has stopped the update from being pushed out. The update was supposed to fix an issue of unintended reboots that had impacted the Sagemcom routers, so they continue to work with the manufacturer on next steps.
