I receive it , plug it in and connect the cable . next I take my rental modem back to the cable company , give they the Mac address from the new modem and I be up and run . the modem I have through the cable company -lrb- Charter -rrb- be a DOCSIS 1.1 Motorola . I be far from reach the speed I be pay for with the they modem . this cm100 modem make a definite speed improvement over the Moto modem I be rent and I do not have to pay the monthly rental fee . over all it do what it be suppose to . the led for the display be not overly bright and annoying like the Motorola modem display . it can be wall mount . it look nicer in person than it do in the photo . it can be hook up with a ethernet cable or usb . I be kind of leary about buy it because of the problem I have have with multiple linksy router . there be only so many time a person can reset a device before they want to throw it across the room . I go to a trendnet wireless n router a couple of year ago and I have not have to reset it once . but anyways , ... back to the modem ! I have not have any problem with the modem at all or lose connection require reset . this modem be a DOCSIS 2.0 which should work fine for internet speed up to the lower 40 's . if you have faster service than that I would look for a DOCSIS 3.0 .
