RCA DCM 425C Modem USB driver

I got a different modem from Comcast....a Motorola. Then I got a Belkin USB network adapter. You can plug in an ethernet cable into the Belkin and plug the other end into the computer USB input. This works well for older laptops that have no ethernet input. Then you call Comcast and they configure it over the phone and Viola! It works. So if you have an older laptop like I have, get a Belkin F5D5055 Gigabit USB 2.0 Network Adapter. Plug it in to your USB input and then plug in the enthernet cable from Comcast. Hope this helps someone.
