Chapter 1: Introduction Minimum Requirements The Linksys Wireless-B Broadband Router • One Windows 98 SE, Millennium, 2000, or XP PC equipped with: • TCP/IP Protocol, • Internet Explorer 5.0 or Netscape Navigator 6 for web-based configuration, • a CD-ROM Drive, and • an Ethernet Adapter with a UTP CAT 5 Network Cable • Cable or DSL Modem with Ethernet Connection and Internet Access Congratulations on your purchase of a Wireless-B Broadband Router.
IP Addresses Dynamic IP Addresses What’s an IP Address? 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. IP stands for Internet Protocol.
The Wireless-B Broadband Router’s Ports The Wireless-B Broadband Router’s LEDs Figure 1-2 Figure 1-1 The Router’s rear panel (as shown in Figure 1-1) is where all of its connections are made. Internet The Internet port is where you will connect your cable or DSL modem with an Ethernet cable. Your modem connection will not work from any other port. Ports 1-4 These four LAN (Local Area Network) ports are where you will connect PCs, print servers, and any other devices you want to put on your network.
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.
For Wireless Connections: In addition to accessing the Router through an Ethernet connection, a wireless connection can be used to access the Router. After powering on the Router and connecting it to your modem, enter the Router’s IP Address in the Address field of your wireless PC’s web-browser as follows: http://192.168.1.1 and press Enter.
