Turning Off Ad-Hoc Connections in Windows XP

Question: 

What is Ad-Hoc Mode in Wireless Networking?

Answer: 

On wireless computer networks, ad-hoc mode is a method for wireless devices to directly communicate with each other. Operating in ad-hoc mode allows all wireless devices within range of each other to discover and communicate in peer-to-peer fashion without involving central access points (including those built in to broadband wireless routers).

To set up an ad-hoc wireless network, each wireless adapter must be configured for ad-hoc mode versus the alternative infrastructure mode. In addition, all wireless adapters on the ad-hoc network must use the same SSID and the same channel number.

An ad-hoc network tends to feature a small group of devices all in very close proximity to each other. Performance suffers as the number of devices grows, and a large ad-hoc network quickly becomes difficult to manage. Ad-hoc networks cannot bridge to wired LANs or to the Internet without installing a special-purpose gateway.

Ad hoc networks make sense when needing to build a small, all-wireless LAN quickly and spend the minimum amount of money on equipment. Ad hoc networks also work well as a temporary fallback mechanism if normally-available infrastructure mode gear (access points or routers) stop functioning.

Most Wi-Fi software is initially set to ad-hoc mode to seek any Wi-Fi connections available. Mobile users should disable ad-hoc mode when using Wi-Fi hot spots as a security measure.

How to turn off Ad-hoc mode in Windows XP?

  1. Choose Start => Control Panel => Network and Internet Connections => Network Connections. The Network Connections window now opens.
  2. Right-click your wireless connection and then click Properties.
  3. Click the Wireless Networks tab. If you can’t find Wireless Network tab, check if your Wireless Adapter is set at “Windows Zero Configuration (WZC)”
  4. Click the Advanced button.

  5. Select the Access Point (Infrastructure) Networks Only radio button.

  6. Click Close and then click OK in the Wireless Network Connection Properties dialog box. You’re now protected from accidentally making an ad-hoc connection.
