Everything works fine including file sharing.
I have just bought a USB external drive. It works perfectly when plugged into a USB port on one of the PCs; I can even share it.
But when I plug it into the other PC it also works fine but the broadband connection drops. Every time. And I can't use broadband again until the drive is disconnected!!
This seems very strange.
Both PCs have XP.
Can somebody help please?
