I'm not very computer savy so I'm asking a question that may sound stupid. How does internet speed work? I'm coming from Arkansas where I was paying for 50mbs which was the fastest available, however we were only actually getting around 25 according to our devices. Now that we are in Arizona, 250 was offered and my kids got excited. We just did a test and we're only actually getting around 45. Is this normal? We have a booster that hasn't been hooked up yet but I really don't understand why that is even needed if 250 is advertised.
