i have the black gateway which picks up 1 to 2 bars of signal. I decided to purchase a wilson booster to get a better signal. Now I get 4 to 5 bars. Unfortunately, after about 10 minutes or so my latency goes from 40 to 60 up to 400 or more which makes the boosted signal useless. I thought it was the booster setup, so I replaced it with a new one. Still does the same thing. When I just use the gateway everything works fine but my up/down speeds are reduced from 15mps/5mps to 3mps/3mps. Any thoughts on what is causing this. T-mobile customer service was not able to help me with this.
