When I attempt to create a network connection in Windows Vista, there is no "ad hoc network" option available. Why is this?

The options available are (translated):

  • Connect to the Internet
  • Configure a wireless router or access point
  • Create a remote connection
  • Connect to a workplace

You need a Wireless Card to do Ad hoc. –  Michael B. Sep 9 '09 at 20:33
    
I assume that my network card is wireless since I can locate other computers, and the only network connection going through a wire to my computer is my internet connection. Regardless, is there any way to check whether or not a network card is wireless or not? In the device manager, the device is simply called "NVIDIA nForce Networking Controller." –  Jakob Sep 9 '09 at 20:40
    
After disconnecting my Internet wire I can no longer locate any other computers, so I guess my network card simply isn't wireless. Still, I thought there would be an easy way to find this out inside Windows. Is there? –  Jakob Sep 9 '09 at 20:49

Anyway the real question is, What are you trying to accomplish ? Why are you looking for an ad hoc connection, which is useless when already connected to the network. –  Michael B. Sep 10 '09 at 4:47
    
My guess is that 'starter' versions of Vista and 7 just don't have that option to create and Ad-Hoc connections. –  user86591 Jun 19 '11 at 21:00

Make sure your wireless network card is turned on.

Go in to the "Network and Sharing Center", and on the left click "Manage Wireless Networks", from here click the add button and "Ad-Hoc network" should be one of the options.

However, if your Wireless is on, you should be able to get to it from the screen you were on -

If it isn't there, it is possible you have some sort of other error.

In my device manager under network cards, I have a single device named "NVIDIA nForce Networking Controller" that is not disabled. Additionally, I can find other computers when I activate "Network identification," so I would assume that the card is turned on. –  Jakob Sep 9 '09 at 20:20
    
Nvidia nForce Networking afaik is not wireless. Go to command prompt and type ipconfig and look at device name (or click start and type "network connections" take a look at how many interfaces you have and see if any of them say wireless. –  William Hilsum Sep 9 '09 at 20:54

Caught me out too, this one. It is there - just scroll down with the side scroll bar!

To help others, not all wireless adapters can host a connection.

From answers.microsoft.com they suggest running:

netsh wlan show drivers

Look for "Hosted network supported". If you see no, you're out of luck
