Safeguarding Your Network

2-3

If using multiple access points, it is better if adjacent access points use different radio 
frequency channels to reduce interference. The recommended channel spacing between 
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).

The time it takes to establish a wireless connection can vary depending on both your security 
settings and placement. WEP connections can take slightly longer to establish. Also, WEP 
encryption can consume more battery power on a notebook computer.

Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 
feet. Such distances can allow for others outside your immediate area to access your network.

Unlike wired network data, your wireless data transmissions can extend beyond your walls and 
can be received by anyone with a compatible adapter. For this reason, use the security features of 
your wireless equipment. The Dual Band Wireless-N Modem 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:

•

WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared 
Key authentication and WEP data encryption block all but the most determined eavesdropper. 
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.

•

WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared 
key to perform authentication and generate the initial data encryption keys. The very strong 
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible 
to compromise. 

 

1) Open system: easy but no security.

2) WEP: security, but some performance impact.

3) WPA-PSK: strong security.

4) WPA2-PSK: very strong security.
