Ad-Hoc Network

[armenh]

I am trying to create an ad-hoc network on windows vista home premium. I take the following steps, I go to manage wireless networks>add>create an ad hoc network>no authentication and save the title> then it says windows could not set up the network. Important to note, I do this while I am connected to a wired internet network, even if wifi is on or off it doesnt work. Also without connected to the wired network it still doesnt work. Any suggestions on what may be wrong? Thanks
