I have very poor internet service. The salesman told me the Boost 30 would be fine for my family of six with several computers, phones, tablets, tv's etc. My boy can not even play a video game on tv due to the lag time. I can not even use my main computer if someone else in on. It costs a great deal of money each month to not be able to even use it properly????? I need a service man to come out and check everything please, asap.
