Make sure you understand (unlike me) that this is an extension of your router, and an indirect extension of your modem! Plug this box into the out on your router, THEN plug all your other devices into this box. Basically. . .. . Modem to Router, Router to this box and finally all other devices off this box. I may be a bit repetitive here, but I just want no one else to waste a hour of their time trying to figure out that concept.
I was thinking that if I plugged the modem into this and then everything else into it, it would work. It didn't. Sometimes I feel like Bill Gates, other times I feel like a complete moron. I'm giving this five stars because I just got it to work and haven't had enough time to see it do anything wrong.
