The Compact Wireless-G Broadband Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. Front Panel Ethernet 1-4 These ports connect the Router to your networked PCs and other Ethernet network devices. Internet The Internet port is where you will connect your broadband Internet connection. Power The Power port is where you will connect the power adapter. Ethernet 1-4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is connected to a device through that port. A flashing LED indicates network activity over that port. Wireless (Green) The WIRELESS LED flashes when there is a successful wireless connection. Internet (Green) The INTERNET LED lights up when there is a connection through the Internet port. Power (Green) The POWER LED lights up and will stay on while the Router is powered on. When the Router goes through its selfdiagnostic mode during every boot-up, this LED will flash. When the diagnostic is complete, the LED will be solidly lit. Bottom Panel Stand Reset Button The Router's Reset button is located on the bottom panel. To access the button, turn the stand perpendicular to the Router. Use a sharp object like a pencil to push in the button. Reset There are two ways to reset the Router's factory defaults. Either press the RESET button, for approximately eight seconds, or restore the defaults from Administration > Factory Defaults in the Router's Web-based Utility. Compact Wireless-G Broadband Router 4 Chapter 2 Wireless Security Checklist Chapter 2: Wireless Security Checklist Wireless networks are convenient and easy to install, so homes with high-speed Internet access are adopting them at a rapid pace. Because wireless networking operates by sending information over radio waves, it can be more vulnerable to intruders than a traditional wired network. Like signals from your cellular or cordless phones, signals from your wireless network can also be intercepted. Since you cannot physically prevent someone from connecting to your wireless network, you need to take some additional steps to keep your network secure. 4. Enable encryption Encryption protects data transmitted over a wireless network. Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalency Privacy (WEP) offer different levels of security for wireless communication. A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP, because WPA/WPA2 uses dynamic key encryption. To protect the information as it passes over the airwaves, you should enable the highest level of encryption supported by your network equipment. WEP is an older encryption standard and may be the only option available on some older devices that do not support WPA. 1. Change the default wireless network name or SSID Wireless devices have a default wireless network name or Service Set Identifier (SSID) set by the factory. This is the name of your wireless network, and can be up to 32 characters in length. Linksys wireless products use linksys as the default wireless network name. You should change the wireless network name to something unique to distinguish your wireless network from other wireless networks that may exist around you, but do not use personal information (such as your Social Security number) because this information may be available for anyone to see when browsing for wireless networks. General Network Security Guidelines Wireless network security is useless if the underlying network is not secure. · · · · Password protect all computers on the network and individually password protect sensitive files. Change passwords on a regular basis. Install anti-virus software and personal firewall software. Disable file sharing (peer-to-peer). Some applications may open file sharing without your consent and/or knowledge. 2. Change the default password For wireless products such as access points, routers, and gateways, you will be asked for a password when you want to change their settings. These devices have a default password set by the factory. The Linksys default password is admin. Hackers know these defaults and may try to use them to access your wireless device and change your network settings. To thwart any unauthorized changes, customize the device's password so it will be hard to guess. Additional Security Tips · · Keep wireless routers, access points, or gateways away from exterior walls and windows. Turn wireless routers, access points, or gateways off when they are not being used (at night, during vacations). Use strong passphrases that are at least eight characters in length. Combine letters and numbers to avoid using standard words that can be found in the dictionary. · 3. Enable MAC address filtering Linksys routers and gateways give you the ability to enable Media Access Control (MAC) address filtering. The MAC address is a unique series of numbers and letters assigned to every networking device. With MAC address filtering enabled, wireless network access is provided solely for wireless devices with specific MAC addresses. For example, you can specify the MAC address of each computer in your home so that only those computers can access your wireless network.

However, if you'd like to change its advanced settings, use the Router's web-based utility. This chapter describes each web page of the utility and each page's key functions. You can access the utility via a web browser on a computer connected to the Router. The web-based utility has these main tabs: Setup, Wireless, Security, Access Restrictions, Applications & Gaming, Administration, and Status. Additional tabs will be available after you click one of the main tabs. NOTE: When first installing the Router, you should use the Setup Wizard on the Setup CD-ROM. If you want to configure advanced settings, use this chapter to learn about the web-based utility. Setup > Basic Setup Internet Setup The Internet Setup section configures the Router to your Internet connection. Most of this information can be obtained through your ISP. How to Access the Web-Based Utility To access the web-based utility, launch the web browser on your computer, and enter the Router's default IP address, 192.168.1.1, in the Address field. Then, press Enter. A password request screen will appear. (Non-Windows XP users will see ...
