My Network

I have five [!] computers on my home network using the at&t modem-router and their DSL line.  All now run on Windows XP.  Two of them were on Windows 98 sitting side by side.  When one of them had a hard-drive failure I managed to replace it with a similar refurbished unit with Windows XP.  Then it was time to install XP (that I bought some time ago) on the other one.  A third desktop sits upstairs in my bedroom.  It uses a Netgear wireless adapter.  I have a laptop which also requires an adapter.  Not long ago I bought an Acer netbook which I love.  It uses XP and has wireless built in.  Finally I have a MyBook external hard drive attached to the bedroom computer which backs everything up. By the way, the two side-by-side computers have Ethernet connections to the router.
