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.
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.
2. Change the default password
For wireless products such as access points and routers, 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.
4. Enable encryption
Encryption protects data transmitted over a wireless network. Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalent 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.

General Network Security Guidelines

• 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.

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 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.

Advanced Configuration

Chapter 3: Advanced Configuration

After setting up the Adapter with the Setup Wizard (located on the CD-ROM), the Adapter will be ready for use. However, if you want to change its advanced settings, use the Adapter’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 networked with the Adapter.
How to Access the Web-Based Utility
Use a web browser to access the web-based utility.
If the Adapter is connected to a network with a DHCP server (usually the network router), then the Adapter will obtain its IP address from the DHCP server. If there is no DHCP server, then the Adapter will use its default static IP address, 169.254.1.250. (If you set a permanent static IP address on the Adapter through the web-based utility, then enter the static IP address instead.)
2. In the Subnet mask field, enter 255.255.0.0.
NOTE: The steps to assign a static IP address to
the Ethernet adapter on your computer vary by operating system. For instructions, please refer to the help documentation of your specific operating system.
After you have assigned your Ethernet adapter with a static IP address, launch your web browser, and enter the Adapter’s IP address (the default setting is 169.254.1.250) in the Address field. Press Enter.
A password request screen appears. (Non-Windows XP users will see a similar screen.) Leave the User name field blank. Enter the password you created during the Setup Wizard. If you did not create a new password, use the default password admin. (You can set a new password from the Administration > Management screen.) Click OK to continue.
Password Screen
NOTE: If you do not know the Adapter’s IP
address, then find its IP address in the DHCP clients table of your router. (Refer to the documentation for your router.)
If you cannot locate the Adapter’s IP address, you can reset the Adapter; press the Reset button on the Adapter for approximately five seconds, using a straightened paper clip. This will reset the Adapter back to the factory default settings. The Adapter will request an IP address from the DHCP server (usually the network router). If no DHCP server is found, then the Adapter will use its default static IP address, 169.254.1.250, until it detects a DHCP server and is assigned a dynamic IP address.
If the Adapter is not associated with a router and is using the factory default settings, connect a computer to the Adapter using an Ethernet connection to access the web-based utility. You will need to configure the Ethernet connection on the computer with a static IP address and subnet mask.
The IP address of your Ethernet adapter should be set to a specific IP address.
NOTE: If the password request screen does not
appear, wait two minutes and try again.

If you want to set a permanent static IP address for the Adapter, then select Static IP.
If you select Static IP, then complete the following fields:
• Static IP Address Enter a unique IP address that will
be used to access the web-based utility.
• Subnet Mask Enter the subnet mask of your wired
network.
• Default Gateway Enter the IP address of the default
gateway for your network (in most cases, this is your router).

In case the wireless router (or access point) detects an association of a non-HT legacy device, it will signal all the HT devices to use RTS/CTS or CTS2Self mechanisms before each data transmission. This feature also supports all 802.11n standard protections, including MIMO.
The RTS/CTS option provides better coverage but lower throughputs when compared to CTS2Self, because the RTS/CTS option includes acknowledgement from the receiving device. To use the RTS/CTS option, keep the default, RTS/CTS. The None option may cause collisions between HT and legacy packets. To use the None option, select None. To use the CTS2Self option, select CTS2Self.
