Announcment: The Motorola/Arris SurfBoard SB6183 is now compatible!
Just as an FYI, Comcast is now activating the SB6183 on business connections. Be aware that because this modem is so new, there may be occasional issues getting it activated during these next few months or so. To activate it on your account, send an IM to any of the moderators on this forum. As always, users with static IPs cannot activate this (or any other retail-bought) modem; it is only available for DHCP (non-static) users.
A complete listing of compatible modems can always be found at http://mydeviceinfo.comcast.net
