WHAT THIS PRODUCT DOES
This ADSL modem router connects your computer
to the Internet using an integrated high-speed
ADSL2+ interface. It provides NAT and SPI firewall
to protect your computer from Internet attacks,
and QoS functions to prioritize traffic for smooth
on-line games, streaming multimedia and voice
communication over the Internet, as well as
download of 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.
