this modem be easy to install . if anyone be have issue get this to work with they wireless router try do this : connect the two device together and then hit the reset button on the back of the modem . it take a few minute , but work every time . do not forget to call you service provider to get this provision . they will nee the mac address of the modem to get it online with they network . the only con to this be that it do not support DOCSIS 3.0 . I contact cisco to check on this think it may just be a firmware issue and I confirm that cisco\/linksys do not have a modem that do . other than that this thing be great . I recommend that if you purchase a wireless router to go with this to check out the Buffalo wzr-hp-g300nh . it have a easy setup user friendly interface or you can use the advanced one that come install .
