Good day all ... I have cable internet service through my ISP. They
provided me with a Motorola modem which is attached to the coax cable
feed. I want to provide internet service to my children's computers,
but becasue they are two floors up, the signal is usually poor. While
perusing e-bay and other sites, I've notices that there are a lot of
modems like the one provided by my ISP for sale. If I get one and hook
it up to the cable line in one of my children's room, would that provide
internet access?
Thanks!!

Normally, the ISP will assign only one IP to the modem. What you may do
is
adding a switch so that you can have a LAN for multiple computers.

How would I go about doing that??
Thanks!
 
Hi
If this would work then every one could plug an eBay modem to a Cable TV
service that provides general Internet access, and get it for free (unlike
telephone line that is individual, cable signal lines are shared among the
subscribers in the neighborhood).
You can connect a Router to the Modem and by combination of wire and
Wireless get the Internet to kids too.

That won't work. With cable, the ISP controls each cable modem by
downloading access info into the cable modem from the ISP's head-end
system. If the serial number (etc.) info from your second cable modem
does not match the ISP's info about a paid subscriber, no download
will happen and that cable modem will not transmit your packets onto
the cable. Your ISP will, of course, be glad to sell you a second
subscription to their cable service -- probably at the same price as
your first subscription.

A cheaper solution is to stick a router on the house side of your
existing cable modem, then use wired and/or wireless links from each
of your PCs to the LAN side of that router. Running wires (Cat5 or
better LAN cables) is a PITA, but wired connections are faster and
more reliable and more secure than wireless; speed usually does not
matter, since wireless links are generally faster than cable, but
reliability and security do.
