no complaint . it be easy to set up and forget . it work well with my Linksys router . it be not expensive . and I be not pay the cable company a monthly rental fee . and when I be ready to switch cable isp it be just a phone call because the hardware be mine . hint : you have to give the cable company the MAC address of the new modem . also if you be use it with a router it be not plug and play . you need to give the router the IP address of the modem .
