Who I have the same questioned this topic

Okay so every review I've read talks about how super fast the Mifi 2200 is but it takes forever pages to download and don't even try to watch a video because it stops every 30 seconds to buffer. I thought maybe it was my computer but i have my roku which is a router you have to watch netflix movies instantly  and yeah that doesn't work either movies stops just like the computer to reload. Is there something I can do to speed it up?
