Input:
I grudgingly use Linksys Instant Wireless series products for my wireless b/g network.  This adapter worked fine on my Dell Inspiron laptop running Me, but that was not the computer I purchased it for.  The whole point of a USB adapter is to be able to easily move from one machine to another.  With different operating systems and this adapter, that is impossible.  And Linksys' "tech support," don't even get me started on that nightmare...
