We bought the Cradlepoint CTR500 router below and just love it with our ATT data card. Highly recommended if you and the DW or DH fight over the data card or you want to look up campgrounds as you drive down the road. We are really pleased with it and I love to take the cat, a glass of wine and the laptop and sit outside the coach on warm afternoons, while I check email and the net.
