Hans-Georg,

Thanks for your response.

Your suggestions make sense as usual, but my technical competence in
this area extends to knowing exactly how to highlight and delete a file
or folder, but becomes very shaky beyond that level.

I first set up my file sharing network more than three years ago, at
which time I used a dial-up connection and had a crossover cable
between the two computers, (At that time, you were very helpful in
setting up a file-sharing network ). About a year ago, I got a
broadband, DSL, connection but the file-sharing network seemed to
migrate to the wireless system without intervention on my part.
Anyway, I've now forgotten how to "navigate them through the
workgroup." Could you outline the steps to refresh my memory?

I often become confused about the meaning of the term "network" in
these discussions. My computers are linked to the Internet by a
wireless "network;" the desktop connected to the router by cable and
the laptop connected by wireless card. Then, I also have a
File-and-Printer-Sharing "network," consisting of the desktop and
laptop, whereby, I suppose, they communicate with each other
"wirelessly." In your last paragraph, could you possibly mean that I
should diconnect the cable connecting the desktop to the router?

Best regards,
Joseph
