The Wireless Access Point Router with 4-Port Switch provides the ideal solution for connecting your wireless network to a high-speed broadband Internet connection and a 10/100 Fast Ethernet backbone. 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. This cutting-edge combination of wireless router and switch technology eliminates the need to buy an additional hub or switch, and extends the range of your wireless network. Now your entire wireless network can enjoy blazing broadband Internet connections supported by its robust switched backbone. With the dual-function speed and power of the Wireless Access Point Router with 4-Port Switch, your network will take off at speeds faster than you ever imagined possible. The Router allows you set up a local network with your PCs and connect to the Internet using the global IP addresses from the AT&T Broadband network. You can also share files and printers securely on your local network. The Router also acts as an Access Point for a local wireless network, so when you add a Linksys Wireless PC Card to your PC, you can wirelessly connect to the Router. Features · · Capable of up to 128-bit WEP Encryption Includes one Ethernet Cable to Connect to a Cable Modem 1 Instant WirelessTM Series Wireless Access Point Router with 4-Port Switch Think of the Router as a network device with two sides. The first side is made up of your private Local Area Network (LAN) of PCs. The other side, the public side, is the Internet, or the Wide Area Network (WAN), outside of your home or office. IP Addresses What's an IP Address? IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its "location," or address, on the network. This applies to both the WAN and LAN connections.

The Router connects your Local Area Network (LAN), or the group of PCs in your home or office, to the Wide Area Network (WAN), which is the Internet. The Router processes and regulates the data that travels between these two networks. 2 3 Instant WirelessTM Series Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as PCs and print servers. These IP addresses are called "dynamic" because they are only temporarily assigned to the PC or device. After a certain time period, they expire and may change. If a PC logs on to the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address. DHCP (Dynamic Host Configuration Protocol) Servers DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. PCs and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The PC or network device obtaining an IP address is called the DHCP client. The Router's WAN port is, by default, set as a DHCP client. Wireless Access Point Router with 4-Port Switch The Wireless Access Point Router's Ports Figure 1-2 The Router's back panel (as shown in Figure 1-2) is where all of its connections are made. WAN The WAN (Wide Area Network) Port is where you will connect your cable modem with an Ethernet cable. Your modem connection will not work from any other port. These four LAN (Local Area Network) ports are where you will connect networked devices, such as PCs, print servers, and any other Ethernet devices you want to put on your network. If Port 4 is being used, the Uplink Port will not work. The Uplink Port is where you can expand your network by connecting to another switch or hub. Uplinking to another switch or a hub is done by simply running a cable from the Uplink Port to the other device. The Uplink Port is shared with Port 4. If the Uplink port is being used, Port 4 will not work. The Power Port is where you will connect the included AC Power adapter. Ports 1-4 Uplink Power Antenna Jacks The Antenna Jacks are where the included antennas are connected. 4 5 Instant WirelessTM Series The Reset Button Pressing the Reset Button and holding it in for a few seconds will clear all of the Router's data and restore the factory defaults. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Router, you run the risk of creating conflicts between your PCs' actual IP Addresses and what the Router thinks their IP Addresses should be. You may be forced to reboot each network PC. If the Router locks up, simply press the reset button or power it down for three to five seconds by removing the power cable from the Router's Power Port. Leaving the power off for too long could result in the loss of network connections. Wireless Access Point Router with 4-Port Switch Full/Col Green. This LED also serves two purposes.

Connect an Ethernet cable from one of your PC's Ethernet ports to one of the Router's LAN ports (as shown in Figure 2-2). Do the same with all the PCs you want to connect to the Router. (LAN Port 4 will become inactive if you use the Uplink port.) In addition to accessing the Router through an Ethernet connection, a wireless connection can be used to access the Router. See the "For Wireless Connections" section that follows these connection instructions. Chapter 2: Connecting the Router Before You Start Before plugging everything together, it's always a good idea to have everything you'll need to get the Router up and running. Connecting Your Hardware Together and Booting Up 1. Power everything down, including your PCs, your cable modem and the Router. 2. Connect an Ethernet cable from your cable modem to the Router's WAN port (as shown in Figure 2-1). 4. Connect the Power Adapter (included) to the Router's Power port (as shown in Figure 2-3) and plug the other end into a power outlet. · The Power LED will illuminate green as soon as the power adapter is connected. · The Diag LED will illuminate red for a ...
