Gateway E-4300 Determining if wireless Ethernet is already installed on your computers, To determine if wireless Ethernet is already installed on your computer:

Important IEEE 802.11b and IEEE 802.11g use the same radio frequency. IEEE 802.11a uses a different radio frequency than IEEE 802.11b and IEEE 802.11g. All wireless Ethernet components must use the same frequency. A combination of IEEE 802.11a and IEEE 802.11b or IEEE 802.11a and IEEE 802.11g components will not work. Some wireless devices can broadcast and receive signals on both frequencies.

A mixture of IEEE 802.11b and IEEE 802.11g components will result in your network running at the speed of the slower IEEE 802.11b components.

Tips & Tricks When buying your access point, be sure the model includes

everything your network needs, including:

■ 802.11g support - for next-generation, high-speed wireless communications

■Internet security features - such as a firewall to protect your network from unwanted intruders

■Wireless security features - such as 128-bit WEP encryption

■4-port switch - to eliminate the need for additional network hardware

■DHCP server/dynamic IP address assignment - to automatically configure network and IP addresses
