Let me start from before Dec 25,2010. I run an XP SP3 desktop. Recently replaced wife's XP computer with a Win 7 Ultimate unit. Both were connected to Linksys 4 port and then onto cable modem. No problem with her unit being able to print from my HP Laserjet which is directly connected to my computer. Move to today. Got the kid a Dell laptop running 7 Home Premium 64bit. Also bought a Cisco Linsys E3000 Wireless 4 port. Removed the old 4 port, installed the wireless. All 3 units up and running fine. kid is wireless, me and the wife hard wired. My wife can still see and print to my printer. Can't get the wireless laptop to find my printer. I ask for your wisdom on this problem.
