Hi, I am using a Nokia Siemens router for internet BSNL. The ADSL is connected directly to this router and am connected to internet through ethernet wire to one of the ports behind the router onto my first laptop. The problem is that now when i want to connect my other laptop through Wifi, first i have to unplug the ethernet or switch off the internet on my first laptop, only then does the wifi connect to the internet on the 2nd laptop. Same is the problem when i try using the 3rd desktop pc using ethernet wire. I have to switch off the internet on my 1st laptop, then only i can logg on to internet on desktop also. Kindly help. Thanks Paul.
