"AdHoc 11n" Disable or Enable

In the advanced settings of my wireless adaptor there is "Adhoc 11n" and its disabled, can someone please tell me what will happen if I enable it?

I have that also and its also disabled...

In general adhoc is used to setup a temporary wireless connection between your computer and another wireless computer so you can exchange files or allow the other computer internet access through your computer.

I do that sometimes but use a program called Virtual Router that turns my HP Windows 7 laptop into a wireless router so I can access the internet with my wireless iPod Touch (4th gen) if I am somewhere with wired internet access but no wireless access.

"Why not experiment a bit and report back." ? Because this is a Q&A forum. 

Perhaps the results of experimentation aren't concrete with any degree of confidence.  Perhaps documentation on the driver settings or scarce if non-existent.   So why not pose the question to a Q&A forum and hope a Microsoft "MVP" doesn't come back with wrong, pre-canned answer or worse, smart-aleck response.

"Ad-hoc" has nothing to do with Google ads.  It is a mode of wireless networking that doesn't require a router.

I created an adhoc wireless connection on my computer and i use it to connect other computers to share internet to, so far it works fine, so how does the setting "AdHoc 11n" disabled or enabled affect it.
