Internet goes down a couple times per day (5g)

@HandyAndy I have seen a few complaints about this, with an unknown cause. However, some people have had success resetting the device (basically setting it up all over again). Maybe there was a hiccup in the setup configuration on the device. You can use the link below for guidance. If that doesn't work, then go back to the local T-Mobile store and ask for a replacement gateway.

I hope this helps!
