I have a usb modem that i use with my computer to access internet. Now I want to share the internet to other computers using ethernet cable. I'm using a switch to direct ethernet cables to other computers. I have right-clicked the internet that i am using and selected the box to allow other computers to use internet from my computer.

The problem is this: when i try to troubleshoot the internet connection from any of the other computer, i'm getting the following error:

Investigate router or broadband modem issues If you are connected to a hotspot or domain network, contact the networ administrator. Otherwise: 1. Unplug or turn off the device. 2. After all the lights on the device are off, wait at least 10 seconds. 3. Turn the device on or plug it back into the power outlet. To restart a router or modem that has a built-in battery, press and quickly release the Reset button.

I have tried doing that over the past 48 hours without success, despite the fact that the connection had been working for one month without problems. No one has changed the settings, since all computers are obtaining ip addresses automatically.

Anyone to help me out in this problem? I will really appreciate.

do your other computers get an ip address assigned? I suggest using wizard to setup connection sharing in network and sharing center. That may work better... –  Vitas Jan 27 '14 at 9:08
