OK, I bet you see fifty of these every week, but humor me on this,\n'cause I'm tearing my hair out.\n\nI'm trying to set up a wireless network. The Linksys router connects\ndirectly to the desktop, which is running XP Professional. The remote\ncomputer, a laptop, is running Vista. As things stand, both computers\ncan use the Internet; the laptop can "see" the files on the Desktop\nover the network, but not vice versa. The XP Desktop doesn't even show\nthe Laptop on the network. No matter what I do, I can't get printer\nsharing to work.\n\nTo sum up:\n\nDesktop: Windows XP Professional\nLaptop: Windows Vista Home\nLinksys router\nAvast anti-virus, Windows firewall\n\nWhat am I missing here? What do I have to do to get file and printer\nsharing working properly, in both directions? I've set up networks\nbefore with no problems, but this one has me stumped.\n\nAll help gratefully received.
