Networks

Just to confirm, you should have run a command prompt (cmd) and typed "ipconfig /all", remembering the 'space'.
You should be able to check in your control panel(assuming windows operating system) for "network connections" and see if you have any problems with your network adapters.
It could be that your network adapter is broken.
Are you trying to connect with a cable or wirelessly?

As you said it is not giving you any information when tried the ipconfig /all - i believe this is a problem with the Network adapters, make sure they are installed properly, if possible uninstall it - reboot the computer and re-install it which will fix this problem. If this does not resolve the issue goto start->control panel->network and internet connections->click on network connections->choose properties by right clicking the local area connection->make sure you find a check mark on the Internet protocol/TCP/ip, also make sure there is a check mark on "show icon notification area when connected" on the same window

If it is a wireless connection try bypassing the router (connecting the modem directly to the computer).. if it works reset the router and configure it again which will fix the issue and you can use it wirelessly..

hope this fixes the problem

Thanks for your time,
