lack feature . Poor Documentation . no support . I be upgrade from dsl to Cable Internet and purchase this modem to avoid the high charge my cable company want to charge I for a modem and wifus . while this modem may work for most people , I find it lack router feature that most router have . I have two computer that run different application that require port forwarding from the router to work . I could only port forward to one computer at a time . if I put the second computer in DMZ then I could not even port forward to the first computer . when I call Motorola for support they tell I I need a older firmware to make it work for I and to contact my cable company to have it download to my modem . why would anyone remove functionality from they firmware ? bad move on Motorola 's part . when I call the cable company , they would not touch it since it be not there modem . in other word no one be willing to support this modem . the only other fix be to put the modem into bridge mode and use a second router that would handle the port forwarding . give the cost of this modem why would I want to use it just as a modem ? I also find the documentation for the modem both online and that package with the unit to be lack . there be multiple box that could be modify that do not have any explanation or description in the documentation . if all you need to do be use wireless to connect a laptop this modem will probably work for you . if you need to do anything more than that you may have problem . if you need support , forget it . Motorola will not update firmware . the cable company will not update the firmware . in the end I have return this modem to Amazon.com and rent a basic modem from my cable company that I be use with my router . at least this way the cable company will support the modem and the router manufacture can not hide behind the cable company .
