what kind of internet connection do you have?
what is a net setter? Is it a 3G/4G connection?
if it connects to your computer via a network cable, use a router and add a switch if you need more then 4 LAN connection.
Net setter is an usb modem.It is connected to one of my three computers. And with switch and through LAN cable I have networked three computers. Now i am getting internet connection only in my one system.
Hope you understood my problem.
