In this project, you set up and configure a wireless access point/router. Configuration steps on various SOHO wireless connectivity devices differ, but they involve a similar process and require you to modify the same variables.

This project assumes that the router is brand new or that it has been reset so any previous configuration has been erased. (To reset the router manually, use the end of a paper clip or pen to press and hold the reset button on the back of the router for 10 seconds.) In addition, this project assumes you are working on a Windows 7 or 8.1 workstation logged on as a user with administrative privileges. The computer must have a wireless NIC (a USB wireless NIC can be installed if the computer does not have an onboard wireless NIC). Also, the project requires the installation CD that ships with the router.

1. From the installation CD, run the setup program on one of your computers on the network (it doesnt matter which one). Follow the instructions on the setup screen or in the accompanying users manual to use network cables to physically connect the computer to the router, plug in the router, and turn it on either before or after you run the setup CD. A computer can connect directly to a network (Ethernet) port on the router (see Figure 6-28), or you can connect through a switch to the router.

2. Connect to the router any other computers on the network that require a wired connection.

3. Firmware on the router (which can be flashed for updates) contains a configuration program that you can access using a Web browser from anywhere on the network. In your browser address box, enter the IP address of the router (for many routers, that address is 192.168.1.1) and press Enter. What is the name and IP address for your router?

4. Youll probably be required to sign in to the router firmware utility using a default password. After you sign in, reset the password so that others cannot change your router setup. Write down your new router password and store it in a safe place.

5. The main Setup window appears, as shown in Figure 6-29. For most situations, the default settings on this and other screens should work without any changes. The setup program will take you through the process of configuring the router. After youve configured the router, you might have to turn your cable or DSL modem off and then turn it back on so that it correctly syncs up with the router. What basic steps did the setup program have you follow to configure the router?

6. Spend some time examining the various features of your router. What is the public IP address of the router on the ISP network? Why is it necessary for the router to have two IP addresses?
