Sharing a Dial-up with Three Computers
Using Windows Internet Connection Sharing
Q. Do you think having three computers share one
phone line is too much? Would you suggest having one phone lines for voice
calls and another for just the computers?
A. Sharing one Internet line between three
computers should work, but it depends on how heavily each of the computers
(users) use it, how fast the MODEM line is, and how much some slow-down is
tolerable by the users. I would try it on the voice line first, and
get a separate line if the cost is justified.
