This ADSL Combo Modem Router connects your computer to the Internet using an integrated high-speed ADSL2+ interface. It provides a NAT firewall and SPI to protect your computer from Internet attacks, and QoS functions to prioritize traffic for smooth online gaming, streaming multimedia and voice communication over the Internet, as well as downloading large files, photos, music and video. When needed, multiple computers at home and the office can also share the high-speed Internet line using the router’s built-in DHCP server/NAT functions and an externally connected Ethernet Switch.
