One thing I would HIGHLY recommend though is putting the proper security on your hub. You can configure it to require a specific access code (string of characters that it must receive from a wireless card). If the card doesn't give the code, it won't talk. If you just leave it open, then anybody and their dog can A) Scam off of your bandwidth to surf the web. B) Possibly hack into your PC's on your inhouse network if they are not adequately protected. This can be a big problem because many people protect their PC's from intruders coming from the internet side. But allow internal users free access.
