1. Introduction
The AT-AR256E 4-Port ADSL Router is the perfect high speed WAN bridge/router. This full-
featured product is specifically designed to connect to the Internet, and directly connect to your
local area network via high speed 10/100Mbps Ethernet. The ADSL router also has full NAT
firewall and DMZ services to block unwanted users from accessing your network.
For gaming users, the ADSL router is already pre-configured for several low latency game ports.
Just click on the game you are playing online and the rest is done for you.
The ADSL router is fully compatible with all computers. As long as your computer has a Ethernet
interface and is running a TCP/IP stack, the computer can have high speed WAN access. So,
plug in the ADSL router (refer to Quick Installation Guide), configure it (per your ISP’s
requirements) and enjoy fast Internet access like never before.
