In order to use three computers sharing one Internet connection they have to
be connected to the same Router, then by default they are on the same
network, there is No way around it. If sharing files is not needed the
sharing on the computers can be set to off, but the computers are still on
the same network.
I do not know if the sharing creates the problem, or there is DHCP
assignments that do not work well.
Your wireless Router has to be configured like this - Using a Wireless
Router as a switch with an Access Point -
All the IP assignments need to be done by the Modem/Router, make sure that
its DHCL server can give at least four IPs.
