Wireless
Important: Changes to the wireless web pages should be made from a PC that is hard
wired to the gateway, i.e. via Ethernet.
The Wireless web pages group enables a variety of settings that can provide secure and reliable wireless
communications for even the most demanding tech-savvy user.
The TCW750-4 gateway offers a choice of 802.1x, WPA and WPA-PSK authentication of your PCs to the
gateway, 64 and 128 bit WEP encryption of communication between the gateway and your PCs to
guaranty security, and an Access Control List function that enables you to restrict wireless access to only
your specific PCs.
The wireless function will probably work in your home as shipped from the factory. In addition, the
factory default wireless channel setting may not provide optimum changes are recommended from the
factory defaults, to secure your wireless communications and provide optimum performance.
Performance
Because your wireless communication travels through the air, the factory default wireless channel setting
may not provide optimum performance in your home if you or your neighbors have other interfering
2.4GHz devices such as cordless phones. If your wireless PC is experiencing very sluggish or
dramatically slower communication compared with the speed you achieve on your PC that is wired to the
gateway, try changing the channel number. See the 802.11b/g Radio Web Page discussion below for
details.
Authentication
Authentication enables you to restrict your gateway from communicating with any remote wireless PCs
that aren’t yours. The following minimum authentication-related changes to factory defaults are
recommended. See the 802.11b/g Radio and Access Control Web Page discussions below for details.
Network Name (SSID) – Set a unique name you choose
Network Type – Set to Open
Access Control List – Enter your wireless PCs’ MAC addresses
