I am a little behind the times when it comes to networking so although my setup is working fine now I need some help for some upcoming upgrades. I currently go from my cable modem through a wired router (linksys) to my PC. I am getting a macbook when my tax return comes in and I would like to get an Airport Express for the airtunes capability along with its size. Another note is that my PC does not have a wireless card so keep that in mind when answering the questions. So not really knowing how these things work bear with me: 1) If I connect the airport to a lan port on my router will it work as a wireless access point for the macbook or does it need to be connected directly to the modem. 2) I realize that networking a mac with a PC can sometimes be a challenge (correct me if I am wrong) but if I do the above connection will the two computers be able to network? 3) If I utilize the printer usb port on the airport will the PC still be able to use it through the wired connection (I guess this depends on the answer to 2)? Thanks in advance for any help.
