very easy to install . you have to contact the internet provider with the new MAC number on the modem before you disconnect the old modem . once the provider update the system , just replace the old with the new , connect the cable -lrb- power , cable , ethernet to router or computer -rrb- and do . no software to install or configure . I have this modem work for about 3 week now , without any loss of service . before I have a 3 generation -lrb- docsis 1.0 -rrb- old Cisco Linksys and I have frequent disconnect and have to reboot the modem once\/twice a day . I have this modem match to a CISCO e3200 wireless router and they work great together . highly recommend this modem . the seller service be great too .
