Is it possible to set up the Ubuntu equivalent of a Vista ad-hoc wireless network. Note that I want to set up a network between 2 computers, one running Ubuntu and the other running Vista (obviously wireless).

Also is it possible to send files via bluetooth both ways. Currently I have been able to send files from the Vista laptop to my Ubuntu one. The files seems to land on the Desktop. How can send the files the other way I get this message.

An error occured while sending file 'XYZ' 

Unknown error
Any help would be appreciated
