Getting started2
Setting up the wireless router
The ASUS Wireless Router includes a web graphics user interface (web GUI) that allows you to configure the wireless router using your web browser on your computer.
Note: For details on configuring your wireless router using the web GUI, refer to Chapter 4:
Configuring via the web GUI.
You can set up the wireless router in any of these three operation modes: Router (IP Sharing), Repeater, and Access Point (AP). Set up the wireless router in the Router (IP Sharing) and Repeater modes via the Quick Internet Setup (QIS), and the AP mode via the web GUI.
Note: To set up the wireless router in the AP mode, use Device Discovery included in the support CD to access the web GUI.
Using the Quick Internet Setup (QIS)
The Quick Internet Setup (QIS) function, which is integrated in the wireless router’s web GUI, detects the Internet connection type automatically and guides you in setting up your network quickly.
The QIS web page appears automatically after you connected all your devices and launched your web browser. You may also launch the QIS from the Network Map page in the web GUI. To do this, click Go in the QIS field under Internet status.

Configuring3the
network clients
Accessing the wireless router
Setting an IP address for wired or wireless clients
To access the ASUS Wireless Router, you must have the correct TCP/IP settings on your wired or wireless clients. Ensure that the clients’ IP addresses are within the same subnet as the ASUS Wireless Router.
By default, the ASUS Wireless Router integrates the DHCP server function, which automatically assigns IP addresses to the clients in your network.
But in some instances, you may want to manually assign static IP addresses on some of the clients or computers in your network rather than automatically getting IP addresses from your wireless router.
Follow the instructions below that correspond to the operating system installed on your client or computer.
Note: In the Router mode, if you want to manually assign an IP address to your client, we recommend that you use the following settings:
•IP address: 192.168.1.xxx (xxx can be any number between 2 and 254. Ensure that the IP address is not used by another device)
•Subnet Mask: 255.255.255.0 (same as the ASUS Wireless Router)
•Gateway: 192.168.1.1 (IP address of the ASUS Wireless Router)
•DNS: 192.168.1.1 (ASUS Wireless Router) or assign a known DNS server in your network
