    Wireless Ad Hoc Networking 

    A continuity from Cheap “Poor -man’s” Networking , if both computers have wireless

    capabilities, then a connection can be setup to connect them through the air. The

    downside to this method is that wireless security such as WAP2, WAP, or WEP

    cannot be enabled as they are not supported under computer-to-computer directnetworking. This type of wireless networking is also known as “Adhoc connection”

    ( From wordweb.info, “ad hoc” means “for or concerned with one specific purpose”).

    An assumption is made that you have already installed the wireless adapters or cards

    on the computers and they are working well. For the sake of simplicity, the two

    computers will be called DAD and MOM respectively.

    ON “DAD“ 

    1. Right-click “My Computer”, click “Properties” 

    2. Click “Computer Name” Tab 

    3. Click “Change” 4. A window should pop-up. Specify a name for the computer.5. Click “Workgroup” and specify a name. (We will call the computer DAD and the

    workgroup HOME)6. Click OK

    7. Click OK in the computer properties windows.

    (You may have to restart the computer. If you are prompted to, do so)

    Configuring Wireless Adaptor

    1. Go to Start > Control Panel > Network Connections > Network Connections Right-

    click on your wireless adaptor, click “Properties” 

    2. Click “Configurations” 

    3. The options available in the configurations will widely vary between wireless

    adaptors, but the main things that that you want to make sure are:

    The type of connection is set to Adhoc and not InfrastructureThe security settings are off  (It may be called “B/G Protection”,

    nevertheless, set this to “none” or “off” On some occasions, you may come across something that says “SSID”

    with a textbox corresponding to it. In this entry, you can specify a

    name for your network. Let’s just call it “Home” for now 

    4. After altering the configuration settings, click “OK” to save the changes, and click“OK” again in the wireless adaptor window to exit 

    5. Right-click again on your wireless adaptor, click “Properties” 6. Click the tab “Wireless Network”

    (The “Wireless Network” tab is not visible on my computer!?) 

    It simply means that your wireless adaptor is currently being controlled by a third

     party software, and as such Windows is unable to take control of it. Here are some

    resolutions:

    Do the equivalent changes in the third-party software. Although

    the interface will be slightly different, the fundamental is still

    the same OR  

    Disable third-party software, and let Windows regain control.

    Right-click on the icon of your wireless adaptor in the system

    tray (where your computer digital clock is located), click “UseWindows Zero Configuration”. In addition, just to make sure

    that Windows has really activated its control, go to Start > Run

    > type in “ services.msc” (without quotation marks) and press“Enter” In the new Window, scroll down until you can see the

    entry “Windows Zero Configuration”. Double-click on it and

    make sure “Startup type” is set to “Automatic”. 

    7. Click  “Add” under “Preferred Network” 

    8. In the new window, type in the same SSID key that you may have specified in step

    3. Otherwise, let’s call it “Home” for now. Under “Network Authentication”, select

    the option “Open” in the dropdown menu. Having done that, select “Disabled” under“Data encryption”. Lastly, place a tick for the option “This is a computer -to-computer

    (ad hoc) network, wireless access points are not used”. The end result should look

    something like this. Click “OK” to save. 

    9. Click “OK” to exit the wireless adaptor window

    Configuring IP1. Go to Start > Control Panel > Network Connections > Network Connections

    2. Right-click on your wireless adaptor and click “Properties” 

    3. Under the heading “This connection uses the following items”, click “Internet

    Protocol (TCP/IP)

    4. Click “Properties” 

    5. A new window should pop up, click “Alternate Configuration” 

    6. Click “User configured” radio button 

    7. Here, you can specify the address. For computer DAD, specify the IP as

    192.168.0.2, subnet mask as 255.255.255.0, Default gateway as 192.168.0.1. Under

    “Preferred DNS Server”, enter the value “208.67.222.222″. As for “Alternate DNSServer”, enter the value “208.67.220.220″. These values are sourced from OpenDNS,

    which will enable the computer to understand the numerical address details of awebsite

    8. Click “OK” 

    9. Click “OK” under the LAN connection properties. 10. You are done for computer DAD 

    ON “MOM“ 

    1. Right-click “My Computer”, click “Properties” 

    2. Click “Computer Name” Tab 

    3. Click “Change” 

    4. A window should pop-up. Specify a name for the computer.

    5. Click “Workgroup” and specify a name. (We will call the computer MOM and the

    workgroup HOME)6. Click OK
