Would love for some help! I added a jetpack with unlimited data for my parents to use at their house. They use Verizon on their phones without a problem to stream Netflix, etc. When using the Jetpack, it continually stops and restarts. I initially thought it was a problem with the Jetpack, but I brought it to my house and it works perfectly. What could be causing it to not work properly at their house? Specifically with the Roku attached to their t.v.?
