Smart authentication?

Can anyone explain to me what is the tab authentication on the local area connection for? It says about smart card authentication, authenticate when computer information is not available or available. Should I leave that checked or un-checking it will make my connection faster?

Thanks

That tab is enabled by default in XP..  It will not affect your network speed, but is only used for authenticatin via a Smart Card, which is an external device used in highly secure environments..  This is specific to 802.1x environments, but Smart Cards can also be used VPN's, etc..

Personally, I would leave it alone..

If you dont know what it is it is better to leave it unchecked . I dont think it will improve the performance .

Here is another link that goes into a little bit greater detail. If you are using this adapter for internet, then you can uncheck everything.  It is mostly used for wireless networks(fixed wireless) but can be used for wired ethernet as well. Unchecking them shouldn't give you any performance in speed.
