Thanks. I do not have any ports left on my Linksys 4 port router. I have done a little research and think I have found what I need.

1- Get the Linksys - PSUS4 - USB 1.1 Print Server with Built-in 4-Port Network Switch. Free up one router port, attach switch to existing router and I have 4 more ports and a USB 1.1 printer port. My only concern is the 1.1 USB. Is it going to be Slow? Should I look for a printer switch with a USB 2 or maybe a USB 3?

With extra ethernet ports I can attach my laptop to an open port and backup as needed.

2- Get the Western Digital 1TB My Book World Edition WDH1NC10000N Desktop Network Attached Storage. This allows me to backup all computers on the network and allows my wife to print to the networked printer, even if my computer is off. 

Two questions about the NAS. Will it limit the number of computers I can back up? Looked at a Seagate STAM1000100 FreeAgent GoFlex Home 1TB NAS - 1 TB, USB that seemed OK but it says "backup up to 3 PC's". Can't get an answer to PC limits on this NAS without calling WD on Monday.

The OS I will be using Win 7 Pro 64 bit. Am told it has good network software, good backup software and allows use of Win XP programs. Think I heard somewhere that some external HD will not work with 64 bit. True? What about setting up a Win 7 64 bit network and expecting Win 7 32 bit to work on it? I have that on my laptop. I also have 2 other computers that currently run Win XP 32 bit but am upgrading to Vista 64 bit. I do not see any problem in getting all these computers to work on the network, correct?

Thanks for your help. I know I have asked a lot of questions. Just want to make sure the system I plan the build will work well before I buy stuff, set it up and find it won't work. I am not a computer tech but was an electronics tech before I retired. I have been upgrading / building computers since the days of DOS. I should know more about computers than I do, but I only work on them every 2 years or so. A lot changes with computers in that time.
