Summary: I tried to connect it to my existing router that is also made by Linksys/Cisco. It didn't work. I called Linksys support hoping that since both modem and router are by the same company, they would help.
Summary: Have used this product for a few months now.
Setup was a breeze, just followed the instruction leaflet.
Initializes fast when you turn it on (compared to my previous Terayon 715 modem)
Small form factor - doesn't take up too much desk space.
Interfaced to my Belkin wireless with no issues.
