Is anyone else having problems with a changing IP address?

I have made 7 different calls to Hulu in the last 30 hours, due to the error page that says that it looks like I am not at home. My i.p. Address has changed multiple times. Each time, I am asked if I just traveled to Belleview WA, or Kansas, etc. or moved from one of the many places. 3 times today I have called in & each one tries to override those locations, and once again, they have to take all of my info, & build me back in. This is a well known T-Mobile problem.  I had trouble with this when I first got the Gateway for a week or so, then for the 6 months there was no problem with THAT issue. Now, suddenly, I'm back at square one. Had I known that TM does not interface with Hulu, had I known that the speeds would fluctuate so wildly, & that the service would drop at least twice a day, if not more, I never would have signed up. The last month, at least half of the mornings we woke up to no internet. I have unplugged this modem & rebooted it countless times. Of course, the gateway always says my connection is Good!                                                                                                                                                                                                                                                                                                                                                                  They clearly were not ready for load on the cell network. I have heard dozens of excuses about the engineers accidentally moving me from one tower to another, blah, blah, blah. Troubles have been escalated to 2nd tier, but no one ever calls back. I have been looking into other isps, like Xfinity, & it seems that even though it has some issues from time to time, it's far better than this, & a lot faster.  I am DONE.
