I can not believe how quick and painless this modem be to install . Unpack box , shut down computer , plug in power and cable to modem , turn computer back on , wait until all modem light have activate , call Comcast so they can see you modem , and voilum - I be up and run . from unpack the box to be online be less than 15 minute . and most of that time be shut down my computer and bring it back up again . I wish everything I hook up to my computer be this easy .
