So far, I've been very pleased with our Cradlepoint router and Verizon air card. Although we do not have an amplifier or external antenna, I have not had any issues connecting to the internet albeit sometimes at speeds slower than I would have liked.

I'm also looking at the new Verizon 4G air card. Should be a fairly dramatic improvement in speed but their 4G service is not yet fully deployed beyond most major cities and airports according to our local office. They expect 4G service here in Port Saint Lucie sometime during the first quarter of 2011.
