3. Conguring the Wireless Router
Note: 1) Before you start, we recommend using a wired connection for initial configuration, which will avoid possible setup problem due to wireless uncertainty. 2) ASUS also provides an EZSetup button for fast wireless conguration. If you prefer EZSetup to arrange for your wireless network conguration, please refer to chapter 6 for more information. The ASUS Wireless Router can be configured to meet various usage scenarios. Some of the factory default settings may suit your usage; however, others may need changing. Prior to using the ASUS Wireless Router, you must check the basic settings to guarantee it will work in your environment. Conguring the ASUS Wireless Router is done through a web browser. You need a Notebook PC or desktop PC connected to the ASUS Wireless Router (either directly or through a hub) and running a web browser as a conguration terminal. The connection can be wired or wireless. For the wireless connection, you need an IEEE 802.11g/b compatible device, e.g. ASUS WLAN Card, installed in your Notebook PC. You should also disable WEP and set the SSID to default for your wireless LAN device. If you want to congure the ASUS Wireless Router or want to access the Internet through the ASUS Wireless Router, TCP/IP settings must be correct. Normally, the TCP/IP setting should be on the IP subnet of the ASUS Wireless Router. Note: Before rebooting your computer, the ASUS Wireless Router should be switched ON and in ready state.

1) ASUS Wireless Router Wired Connection
One RJ-45 cable is supplied with the ASUS Wireless Router. Auto crossover function is designed into the ASUS Wireless Router so you can use either straight-through or crossover Ethernet cable. Plug one end of the cable into the WAN port on the rear of the ASUS Wireless Router and the other end into the Ethernet port of your ADSL or Cable modem.

Wireless-Connection

Note: If conguration is done via wired connection, ignore this. Refer to your wireless adapter users manual on associating with the ASUS Wireless Router. The default SSID of the ASUS Wireless Router is default (lower case), encryption is disabled and open system authentication is used.
2) Setting IP address for Wired or Wireless Connection

Get IP Automatically

The ASUS Wireless Router incorporates a DHCP server so the easiest method is to set your PC to get its IP address automatically and reboot your computer. So the correct IP address, gateway, DNS (Domain Name System Server) can be obtained from the ASUS Wireless Router.
Note: Before rebooting your PC, the ASUS Wireless Router should be switched ON and in ready state.

Setting IP Manually

If you want to set your IP address manually, the following default settings of the ASUS Wireless Router should be known: IP address 192.168.1.1 Subnet Mask 255.255.255.0. If you set your computers IP manually, it needs to be on the same segment. For example: IP address 192.168.1.xxx (xxx can be any number between 2 and 254 that is not used by another device) Subnet Mask 255.255.255.0 (same as the ASUS Wireless Router) Gateway 192.168.1.1 (this is the ASUS Wireless Router) DNS 192.168.1.1 (ASUS Wireless Router IP address or your own).
3) Conguring the Wireless Router
Enter the following address in your web browser: http://192.168.1.1 Defaults User name: admin

Password: admin

After logging in, you will see the ASUS Wireless Router home page. The homepage displays quick links to congurate the main features of the router.

4) Quick Setup

To start quick setup, click Next to enter the Quick Setup page. Follow the instructions to setup the ASUS Wireless Router.
1 Select your time zone or the closest

region. Click Next to continue.
ASUS wireless router WL520g supports ve types of ISP services cable, ADSL (PPPoE, PPTP, static IP address), and Telstra BigPond. Since each service has its own protocols and standards, therefore, during the setup process, there are different identity settings demanded by WL-520g. Select the correct connection type. Click Next to continue.

Cable User

If you are receiving services from cable or other ISP assigning IP addresses automatically, please select Cable Modem or other connection that gets IP automatically. If you are using cable services, your ISP may have provided you with hostname, MAC address, and heartbeat server, if true, please ll these information into the boxes on the setting page; if not, click Next to skip this step.

PPPoE User

If you are PPPoE service user, pleae select the second line. You would be required to input the username and password provided by your ISP.

PPTP User

If you are using PPTP services, you would be asked to input the username, password, as well as IP address provided by your ISP.

herk036@adsl-comfort

Static IP User
If you are using ADSL or other connection type that uses static IP addresses, please select the fourth line, then input the IP address, subnet mask, and default gateway provided by your ISP. You could choose to specify certain DNS servers, or select to get DNS automatically.
After setting the connection type, you are to set up your wireless interface,. First, give an SSID (Service Set Identier), which is a unique identifier attached to packets sent over WLANs. This identifier emulates a password when a wireless device attempts communication on the WLAN. Because an SSID distinguishes WLANs from each other, access points and wireless devices trying to connect to a WLAN must use the same SSID. Also, if you want to protect transmitted data, select a middle or high Security Level. Medium : only users with the same WEP key are to connect to this access point and to transmit data using 64bits or 128bits WEP key encryption. High: only users with the same WPA pre-shared key are to connect to this access point and to transmit data using TKIP encryption. The ASUS wireless router configuration page features a convienient approach to setup the WEP Keys: with only a few taps on your keyboard to dene the Passphrase, the system will automatically generate four strings of WEP Keys. For ASUS wireless adaptor users, it is no longer necessary to input long and complicated WEP Keys when connecting the router with the wireless client; the Passphrase provides an easy way for setting up your wireless environment! For example, if we input select WEP64bits encryption mode, input 11111 as Passphrase, then the following WEP Keys are generated as shown in the right picture. Record the Passphrase and the WEP keys on your notebook, then click Save.

Click Finish to continue. You are prompted to save the settings. Click Save&Restart to save the settings to the ASUS Wireless Router and enable the new settings. Next we are to setup encrypted wireless connection for wireless router and wireless client. If you have installed ASUS wireless adaptor as well as the utility, click Start -> Programes -> ASUS Utility -> WLAN Card -> One Touch Wizard to open the connection setup utility on the client end.
Select Connect to an existing wireless LAN (Station) when the welcome window appears, then click Next.
ASUS ONE TOUCH WIZARD searches and displays all the available stations as shown in the picture. Select WL520g and press Next to continue.
The setup wizard then asks for encryption setup. Set Key Length as 64 bits (10digits) as we have previously set on WL-520g, then select Automatic Generation and input 11111 into the Passphrase box. Note: The encryption mode on your client must be the same with that on your wireless router.
Wait for several seconds to get the client connected to the wireless router. Then a screen informing the result of the connection would appear. Press Next to continue. Then you will see the IP conguration screen. Setup the client IP address according to your network condition. After the setup is completed, Click Finish.
For non-ASUS wireless adaptor users, you can set up the wireless connection between your computer and the wireless router with Windows Zero-Configure function. Right click the Network Neighbour on the desktop of your client and click Property, then in the Network Connection window, double-click Wireless Network Connection icon, a window with all available stations appears. Select WL520g and click Connect. The connection process would take about several seconds.
Then a window prompts out asking you to input the network keys, input the 10-digit key you have previously recorded in your notebook, then click Connect to complete connection.
To adjust other settings, click on items on the menu to reveal a submenu and follow the instructions to setup the ASUS Wireless Router. Tips are given when you move your cursor over each item.
4. Commonly Used Advanced Features
The following pages are setup examples of commonly used advanced features. You could setup these features in web browser.
1) How to Setup Encryption

WL-520g Encryption Setup

Please refer to P.7 for encryption setup information or to use ASUS EZSetup features which enable a quick encryption setup through several clicks (Page 25-26).
2) Setting up a Server in Your LAN
Virtual Server is a kind of technology which enables a computer to receive specialized packets from network. It is to assign a certain host to act as a link between inner LAN and outside Web, FTP server. Virtual DMZ provides an all-portmatch function, which grants specied computers unlimited authority to get access to network resources. The difference between Virtual Server and Virtual DMS lies on the ports they enable respectively: Virtual Server just open serveral ports while Virtual DMZ open all ports to the network.

Click Virtual Server in NAT Setting folder to open the NAT conguration page.
Select Yes to enable virtual server. For example, host 192.168.1.100 is set as virtual server with its ports 20,21 (FTP) accessible to outside users. Therefore, FTP requests from outside users would be forwarded to the host.

3 Click Finish.

Click Save & Start to restart the router and apply the setttings.
3) Setting up Switching Hub & Pure AP (Non IP Share NAT)
Connect the LAN port from a DSL or Cable modem to one of the LAN ports on the wireless router.

DSL or Cable Modem

Select DHCP Server in IP Cong folder.
Disable the DHCP Server function.
Click Finish Click Save & Restart.
4) Setting up Net Meeting, MSN, Online Gaming, and Remote Control Programs
Virtual DMZ allows you to expose one computer to Internet, so that all inbound packets will be redirected to the computer you set. It is useful while runing some applications which using uncertain incoming ports. Please use it carefully.
First we are to get the IP address of the host. Open the Windows Start menu and select My Network Places.
Click View network connections.
Right click Local Area Connection and select Properties.
Double-click Internet Protocol (TCP/IP).
Get the current TCP/IP settings.
Click Virtual DMZ in the NAT Settings menu.
Enter the IP address of the host and click Finish.
Click Save & Restart.

5) Setting up DDNS

Dynamic DNS (DDNS) allows user to export host name to Internet through DDNS service provider. Each time the ASUS Wireless Router connect to Internet and get an IP address from ISP, this function will update your IP address to DDNS service provider automatically, so that any user on Internet can access the wireless network or servers behind it through a predened name registered in DDNS service provider.
Click Miscellaneous from IP Cong folder.
Enable the DDNS Client. If you have not acquired a DDNS account, click Free Trial to apply for one.
After clicking Free Trial, you would be directed to www. DynDNS.org, where you could register and apply for DDNS services. Read the policy and select "I have read.".
Enter your user name, e-mail address, password for this account, and then click Create Account.
You would see this message informing that you account has been created. You will receive an e-mail to activate the account.
7 Open your e-mail to nd the
activation letter. Click the hyperlink to activate your account.

8 Then press login.

9 Enter your user name and
password you have set when you were applying for the account.
10 After logging in, you would see

the welcome message.

11 Select Services tab.

12 Click Add Host.

13 Name your hostname and click

Add Host.

14 You will see this message when
your hostname is successfully created.
Fill your DDNS account data in the DDNS Setting page of your router.
Click Finish. Click Save & Restart.
Now we are to verify whether DDNS is working. Click Start menu and select Run. Type in cmd and click OK to open the DOS console.
Type ping wl520g.dyndns. org (your host name). If reply information is displayed, the DDNS is working correctly.

6) Setting up WDS

Wireless bridge, also known as Wireless Distribution System or WDS, allows connection to one or more access points. We now take an example to show how to setup WDS for two APs. In this example, AP1, with MAC address of 00:0E:A6: A1:3F:6E and IP address of 192.168.1.1, will operate in Hybrid mode; AP2, with MAC address of 00:0E:A6:A1:3F:87 and IP address of 192.168.1.2, will also be set to Hybrid mode, but it would not assign IP addresses to clients. Only one DHCP server in the WDS system is allowed, that is AP1 in this example. SSID LAN IP Address Encryption Wireless Bridge MAC Address Allow Anonymous Access Point A WL520g 192.168.1.1 NONE Hybrid Mode 000ea6a13f6e NO Access Point B WL520g 192.168.1.2 NONE Hybrid Mode 000ea6a13f87 NO
1 First, we are to set up AP1. Choose Bridge in the

Wireless folder.

2 Set the SSID as WL520g and
WEP Encryption as None. We suggest AP1 and AP2 using the same SSID.
3 Select WAN & LAN in the IP Cong folder.
4 Conrm that the IP address

of AP1 is 192.168.1.1.

5 Enter the Bridge page again.
6 Select Hybrid as AP mode.
Thus, AP1 will be both AP and WDS. If you want to use wireless function only, please choose WDS Only. When you choose WDS or Hybrid mode, you will see a message demanding a xed channel for WDS.
8 Select a xed channel for

WDS. In this example, we set it as Channel 3.
Enable Connect to APs in Remote Bridge List to connect to the other APs in your list. If you want to allow anonymous user to login your network, you can select Yes in Allow anonymous eld. In this example, we do not allow anonymous users.
Enter the MAC address of AP2, i.e. 000ea6a13f87. Press Add button to add the MAC address to your list.

Press Finish button.

Press Save & Start botton. Then, we are to setup AP2.
Enter the web-based conguration page on AP2. Repeat step 1-2 to setup the same SSID with AP1. Then select WAN & LAN page in IP Cong folder.
Set the LAN IP address of AP2 to 192.168.1.2. Next, we are to disable the DHCP server function of AP2 since AP1 is the only DHCP server in the wireless LAN. Enter the DHCP Server page in IP Cong folder.
Choose No to disable DHCP Server and press Apply botton.
17 Repeat step 5-10. Then enter the MAC address of AP1, i.e., 000ea6a13f6e. Repeat step 11-12. After reboot, WDS would work.
