WiFi Shield on Arduino UNO and Library

Good morinign I have a question on WiFi shiedl (original) and the library : "WiShield di AsyncLabs"?

Can I use this AsyncLabs library (for wifi) and Arduino WiFi shield original? My problem is to use the WiFI original Shield (of Arduino producer) in ad-hoc connection WiFi, and I have found that this isn't possible whit the offical library "WiFi library".

Thank's a lot!

No.

It's not possible. It's a hardware limitation, not a library limitation. The Arduino WiFi shield can not create an ad-hoc network.
