networking

ou are not connected bec you do not have a harp to conect.
Looks like u require a harp or connectors linked to your mordem before to your computer. Go to shop and buy one . Mayby USD 30-40 only .
Or change your modem to ADSL Router D-Link DSL 504T . It has 4 conections built to it which means you can network 4 desktop at at a time .
