Reference Manual for the Model DG834GT 108 Mbps Super Wireless ADSL Router
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.

Implement Appropriate Wireless Security

Note: 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 of 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 DG834GT Super Wireless ADSL 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 allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the DG834GT. Restricting access by MAC address
adds an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
