For the most part, the computers will stand alone (my daughter really doesn't need to have access to all my files), but I am considering getting either DSL or Sat. internet (Direct Duo), and there are some files I would share with the rest of the family. The computers will be in the basement (HP AMD Athlon - main) and the second floor (the old 133), and since this is a townhome I will probably have to run cable (I've already had problems with wireless products in the home, either cross interference or just crappy connections). I don't have a phone line in my daughter's room, but it wouldn't be to difficult for me to wire one up.
I'm not looking for anything spectacular, I just figured that since I'll be giving the computer to my daughter (and my wife) I might as well network them (plus it would be easier to transfer my old files to the new computer instead of copying everything to my Jazz drive, slower but easier). I thought about getting this from eBay because I have a chance to get these real cheap, and while it has been 7 years since I took my networking classes, I can usually muddle my way thru software and harware issues.
Thanks for all your help.
