Just plug it in and see if it works first thing. Next what ROM are you using the stock sharp? If its not supported you can/should update your ROM first besides updating your ROM\'s probably a good thing and that would be an excuse. If it doesnt work after that then you need to look for drivers. If thats the case post here and someoen can help you out if you cant find them
How your going to connect through your wifi card is going to depend on the ROM.
