T-mobile Wifi Gateway Home Internet

I picked up the internet gateway 3 days ago, and I am having to power cycle the unit multiple times a day when the internet just stops working completely. The display on the gateway says I still have service, but clearly the internet has stopped working completely, requiring a power cycle. If this is the way it's going to go, I will have no choice but to reconnect my Cox modem and live with it for the time being.
