Summary: Wireless on my other router failed so I bought this as the modem still worked. Easy to install and backup when I needed to ask a question was quick and efficient. Works perfectly with excellent security system.
Summary: Spent ages trying to get this to work after connecting my ADSL router on the WAN port. Eventually resorted to using one of the 4 LAN ports and leaving the ADSL 4-port router to act as the DHCP server which worked okay, but this limits the LAN ports and it would be no good if you have only have a basic ADSL modem. The box has a label which states "for cable modem" but this isn't shown on the amazon description. Works okay now.
