This modem is dissapointing. Its slick and looks good, but the firmware is crippled, the wireless has a poor range and throughput, and the Gigabit ethernet is not that fast.

An Arris EMTA without the built in Router is a better bet...

Can you PLEASE give instructions on how to change NAT types for online gamers. I have enabled the UPnP but still nothing and I still get NAT errors for a moderate NAT setting.

Where is the option to allow DHCP offers/releases through Coaxial Line? I don't see any coax. devices through the firmware/web ui, however, the STB's on my home network must be connected? Do I need MoCA, or is there an option to enable coax.? Please let me know michaelpcurran@aol.com. Comcast is clueless... They don't support home networking I guess...
