High-Speed Internet Gateway does not work with some apps on T-mobile Home Wifi Internet

so. although i was not able to read all the comments, it sounds like we are all experiencing somewhat of the same thing.   I went from xfinity to tmobile because it was cheaper but notice that the performance to be less than.  I am finding that i cannot go to certain sites that i have been using it just locks up constantly.   So, I would have to go to my incognito mode on google chrome and it would work.  I notice that when i am watching a movie or show on my computer it lags.. buffers.. and sometimes i have to get out of it and come back in in order to get it streaming again.  I mean from day one that the router was plugged and set. I just havent had time to get some help on it. But honestly i dont think they can do anything about it.    I may be returning to Xfinity.
