•
Put the antenna in a vertical position to provide the best side-to-side coverage. Put the
antenna in a horizontal position to provide the best up-and-down coverage.
•
If you are 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.
Wireless Security Options
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 N300 wireless 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 This data encryption mode has been superseded by WPA-PSK and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 rekeying of WPA makes it virtually
impossible to compromise.
Wireless data
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.
