Switch can also be configured to filter internal users’ access to the Internet. A typical router relies on a hub or a switch to share its Internet connection, but the Linksys Wireless Access Point Router with 4-Port Switch channels this connection through the blazing, full duplex speed of its built-in EtherFast 10/100 4-Port Switch.
IP Addresses What’s an IP Address? IP stands for Internet Protocol. Every device on an IP-based network, includ- ing PCs, print servers, and routers, requires an IP address to identify its “loca- tion,” or address, on the network. This applies to both the WAN and LAN con- nections.
The Wireless Access Point Router’s Ports Figure 1-1 The Router’s rear panel (as shown in Figure 1-1) is where all of its connections are made. The WAN (Wide Area Network) Port is where you will con- nect your cable or DSL modem with an Ethernet cable. Your modem connection will not work from any other port.
Full/Col Green. This LED also serves two purposes. When this LED is lit continuously, the connection made through the corre- sponding port is running in Full Duplex mode. A blinking LED indicates that the connection is experiencing collisions. Infrequent collisions are normal. If this LED blinks too often, there may be a problem with your connection.

Unlike IP addresses, which can change every time a computer logs on to the network, the MAC address of a device stays the same, making it a valuable identifier for the network. If your questions are not addressed here, refer to the Linksys website, www.linksys.com.
IP addresses, which are the true addresses on the Internet. For example, www.linksys.com is actually 216.23.162.142. Entering that into your web browser will bring up at the Linksys home page every time. IP and web addresses, however, can sometimes be long and hard to remember.
WEP encryption has been called 40-bit because it uses a 40-bit secret key along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may use either name. Linksys uses the term “64-bit” when referring to this level of encryption.
Page 43
• WEP (64Bit or 128B) Select the level of encryption from the drop-down box. 128-bit WEP encryption is unique to Linksys and may conflict with other vendors’ WEP encryption. Note: In order to utilize WEP encryption, all points in your wireless network must have WEP enabled and be set to the same Key Setting.
Configuring Wireless Security in Windows XP As Windows XP does not allow for the use of the Linksys Passphrase feature with the wireless PC adapters, you will need to manually enter the key gener- ated in the previous section. The following steps will help you enable WEP and enter the encryption key manually for your wireless PC cards, in order to enable your Windows XP sys- tem to communicate with the Router wirelessly.
