The exsiting Linksys Wireless Router connected seamlessly to Clear Modem device. No programming was needed to make the Linksys Wireless Router work with the Clear Modem.
The Modem was very picky about placement. The people at Clear had pointed out where the closest broadcast tower was from the clients' house. A "stand" of books were stacked one on top of another so that the Modem was sitting in front of a window on the top floor of the house facing the broadcast tower. Other locations in the house resulting in a signal that would not allow a laptop to connect to the internet.
The client was also given a hand held Mobile Spot that never connected to the broadcast tower.
Both devices (Mobile Spot and Modem) were given to the client on a 14 day trial. So far, so good. Maybe Clear is your solution to dumping Comcast or AT&T High Speed Internet Access.
