No ip address was asigned from dlink to lap...

Is your DHCP turned on in the D-Link ? It cannot assign an address if it is not enabled. Also bear in mind that a pc may take up to 2-3 minutes to "get" an address - it is relative to the broadcast and beacon interval of the router and the query time of the pc lan card. If DHCP is turned on in the router and it has an address pool, try restarting the PC, if the router has used up it's pool of assignable addresses, it maybe "locked" and cannot release a new one, try pressing the reset button on the router, it is inside a little hole in the back, a pencil works fine for that, hold it until all the lights go out on the front and start flashing. Then restart the pc and it should get an address.
