Implementing Appropriate Wireless Security
Unlike wired network data, your wireless data transmissions can be received well beyond your
walls by anyone with a compatible adapter. For this reason, use the security features of your
wireless equipment. The RangeMax NEXT Wireless Router provides highly effective security
features which are covered in detail in this chapter. Deploy the security features appropriate to
your needs.
There are several ways you can enhance the security of your wireless network:
Restrict access based on MAC address. You can restrict access to only trusted computers so
that unknown computers cannot wirelessly connect to the WNR854T. MAC address filtering
adds an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
Turn off the broadcast of the Wireless Network Name SSID. If you disable broadcast of the
SSID, only devices that have the correct SSID can connect. This nullifies the wireless network
‘discovery’ feature of some products such as Windows XP, but the data is still fully exposed to
a determined snoop using specialized test equipment like wireless sniffers.
WEP. Provides data security. WEP Shared Key authentication and WEP data encryption will
block all but the most determined eavesdropper.
Note: Indoors, computers can connect over 802.11b/g wireless networks at a range of
several hundred feet. Such distances can allow for others outside of your
immediate area to access your network.

WPA-PSK and WPA2-PSK. Provides strong data security. WPA-PSK and WPA2-PSK will
block eavesdropping. Because these are new standards, wireless device driver and software
availability may be limited.
Turn off the wireless LAN. If you disable the wireless LAN, wireless devices cannot
communicate with the router at all. You might choose to turn off the wireless LAN when you
are away and others on the network all use wired connections.
Understanding Wireless Settings
To configure the Wireless settings of your wireless router, type http://www.routerlogin.net into
your internet browser. Enter the default user name of admin and default password of password, or
whatever LAN address and password you have set up. Click the Wireless link in the main menu of
the browser interface. The Wireless Settings menu appears, as shown below.

How to Configure WPA-PSK or WPA2-PSK Wireless Security
To configure WPA-PSK, follow these steps:
1. Click Wireless Settings in the Setup section of the main menu and select one of the WPA-
PSK or WPA2-PSK options for the Security Type. The third option (WPA-PSK [TKIP] +
WP2-PSK [AES]) is the most flexible, since it allows clients using either WPA-PSK or
WPA2-PSK.
Note: Not all wireless adapters support WPA. Furthermore, client software is also
required. Windows XP and Windows 2000 with Service Pack 3 do include WPA
support. Nevertheless, the wireless adapter hardware and driver must also support
WPA. For instructions on configuring wireless computers or PDAs (Personal
Digital Assistants) for WPA-PSK security, consult the documentation for the
product you are using.

Advanced Configuration of the Router
This chapter describes how to configure the advanced features of your RangeMax NEXT Wireless
Router Gigabit Edition Model WNR854T. These features can be found under the Advanced
heading in the Main Menu of the browser interface.
Configuring Port Triggering
Port Triggering is an advanced feature that can be used to easily enable gaming and other internet
applications. Port Forwarding is typically used to enable similar functionality, but it is static and
has some limitations.
Port Triggering opens an incoming port temporarily and does not require the server on the internet
to track your IP address if it is changed by DHCP, for example.
Port Triggering monitors outbound traffic. When the router detects traffic on the specified
outbound port, it remembers the IP address of the computer that sent the data and triggers the
incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer.
Using the Port Triggering page, you can make local computers or servers available to the Internet
for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to
use Internet applications (like CUseeMe).
Port Forwarding is designed for FTP, Web Server or other server based services. Once port
forwarding is set up, a request from the Internet will be forwarded to the proper server. In contrast,
port triggering will only allow request from Internet after a designated port is 'triggered'. Port
triggering applies to chat and Internet games.
Note: If you use applications such as multi-player gaming, peer-to-peer connections, real
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should also enable UPnP according to the instructions at
“Using Universal Plug and Play (UPnP)“ on page -17.
