I have a desktop connected to the internet with a ADSL modem through USB port, a LAN connection to share the internet through a 5 port Switch, my internet speed is 512. Actually I don't use all the ports of the Switch, there are 2 of them that are not in use. My question is: Can I use the ports that are not in use to connect a Wifi access point to share wireless connection? If yes, what do I need to buy and how can I connect it?

Thanks a lot for spending your time reading this, and of course, your helping me.
