I used the Cisco 1710 while telecommuting for my previous company. I no longer have that router, and I need a replacement. Is the 1710 the best (i.e., most affordable while supporting VPN and QoS) for cable modem? I tried using the Cisco Product Advisor, but I see not option for cable modem access. As for the WAN interface issue, is cable modem specific, in that the router specifically has to support cable modem connectivity, as opposed to DSL? Thank you, jm
