How to Create an Ad Hoc Network

Ad hoc networks are temporary wireless networks that allow two computers to share files and an Internet connection. Computers can create a wireless network without the need for a router, especially for a quick network setup. Any computer with a wireless card can connect to one central computer, which acts like a router. Ad hoc networks can be secured with passwords to prevent outside access. Windows provides users with a quick way to create ad hoc networks and share their Internet connections in the process.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Windows XP or later

1. Select your central computer. This computer must remain on at all times in order for other computers to connect to the ad hoc network.

2. Click "Start" and press "Connect To." Choose "Show All Connections."
   If you don't see "Connect To," go to "Control Panel" and select "Network Connections."

3. Click "Set up a connection or network" for Vista operating systems. Choose "Set up an ad hoc network" and click "Next." Follow the steps in the network creation wizard to create your network.
   For XP systems, continue to Step 4. Vista users continue to Step 6.

4. Right-click your wireless connection under "Network Connections." Choose "Properties." Click the "Wireless Networks" tab.

5. Press "Add" to create a new network. Type a short name for your network in the "Network Name" box. Add a password to your network by choosing "WEP" from the "Network Authentication" drop down box. Type a password into the two password boxes.
   Check the "This is a computer to computer (ad hoc) network" checkbox at the bottom of the screen. Press "OK" to create the network.
   Right-click your Internet connection and choose "Properties." Go to "Advanced" and check the "Allow other users to connect through this computer's Internet connection" box. Choose "Wireless" as your connection type. Press "OK" to share your Internet connection.

6. Connect other computers to the ad hoc network. Open the computer's "Network Connections" as stated in Step 2. Right-click the computer's wireless connection and select "View Available Wireless Networks." Select the ad hoc network and press "Connect."

Tips & Warnings

• Use an easy-to-remember password. Use a combination of letters and numbers for added security.
• Never set up an open network if you're sharing personal documents and information. Outside users can intercept and steal information on open networks.
