I have a PC connected to a router via ethernet cable, because in the instructions for the router it specified that at least one computer has to be. Now, I am planning on buying a wireless card for the pc and the airport express for a printer that is currently connected to that pc. I am going to move the printer with the airport to a different room. Would I be able to connect wirelessly to the aiport with the pc while maintaining a wired connection with the router? hopefully, this isn't too confusing.
