The allowed retail business routers by the Comasct system are outdated and limited. In comparison they "lease" a 4 port Cisco unit but only allow Surfboard one port units. Why add additional speed when you funnel it down to one port? Seems like a fixed game where you have to lease from Comcast at exhorbident rates. Only 10 days on Comcast and I miss my Charter Business service. At least they allowed more flexibility on router hardware.
