I gave up on the whole router, modem thing. I had cable internet and went thru 2 modems and 2 routers and it still never really worked right all the time. Cable always said it was either the router or the modem and both the router and modem companies always said their stuff was fine, it must be the other.
I gave up April 15th when....yup, you guessed it, I'm a procrastinator. I couldn't get my internet up long enough to file my taxes.
My cable company said, and I quote: It MIGHT be a problem just in your area; give it about an hour and try again
I called Verizon (my cell phone provider) and asked about their air card, went down with my laptop and picked it up (free, by the way) and they installed it for me. I came home, filed my taxes and haven't looked back!
I LOVE IT...no router, no modem, no hassle!...I won't ever go back if I can help it!
