i have mtnl triband scheme (dont remember the exact name of scheme but its 256kbps, 400mb per month d/l). I have been using it since 3 months (connected through onboard lan) without any problems but nowadays i cant connect through the lan card. Whenever i try to connect the router through the lan card it says "acquiring network address" for a long time and then it shows that "this connection has limited or no connectivity" and it doesn't connects to the net even though all lights are up. But when i connect it throught he usb cable i am able to connect without any problems. Can someone help me on connecting it through my lan card as i dont like to connect it through a usb cable and keep a us port busy.
