use a regular interior wireless router in combination with a special weatherproof enclosure recommended by the router s manufacturer. Usually these enclosures aren t available at the average computer or electronics store, so you will probably need to purchase one on the Internet, either from the manufacturer s website or from an Internet store.

4. Connect the exterior router to your existing interior wireless network, as follows: a. Purchase a CAT5 cable long enough to stretch from the exterior router to the interior router. b. Run the cable from the exterior router to the interior router. This may require you to drill holes in the side of your house and sh the cable through walls. c. Plug one end of the cable into an available Ethernet port on the exterior router, and then plug the other end of the cable into an available Ethernet port on the interior router. d. Power up the exterior router. If the Ethernet cable doesn t supply electricity to the router (which is called power-over-Ethernet ), use an extension cord to plug the exterior router into an exterior electrical outlet.

b. Change the channel of the exterior router so it does not use the same one as the interior router. To avoid interference, only use channels 1, 6, and 11. c. Con gure the exterior router to give it the same security settings as your interior router. d. To avoid con icts, disable the DHCP feature on the exterior router.

Consult the User Guide
Your product s user guide contains answers to frequently answered questions, valuable information about how to access con guration screens and troubleshoot problems, and much more. When you are installing a wireless network or attempting to solve a problem with it, read the user guide rst. Most wireless network products don t come with a printed user guide, so you need to locate it on the CD-ROM that came with your hardware. In many cases, the user guide can be accessed through a window that pops up after you insert the CD. If no pop-up window appears, you can manually search for the user guide by doing the following:
1. Double-click the My Computer icon on your desktop. If this
icon is not available, click the Start button in the lower-left corner of Windows and click My Computer. If you can t nd the My Computer icon anywhere, do the following: a. Right-click in the empty space on your desktop. b. Select Properties. c. A window opens. Click the Desktop tab.
