I have an Inspiron 600M with an Intel Proset wireless network card.  I am experiencing poor reception on this laptop in the exact location of my desktop PC that is receiving excellent reception.  When I boot up the laptop in this location, I initially connect to the network and receive adequate reception, but after a few minutes, the speed of my connection drops even though the signal strength remains good.  Eventually, I get a limited connectivity warning and can no longer receive the network signal.  I can repair the connection in Windows and go through the same sequence until reception is eventually lost again.

 

Does anyone know if there is anything I can do to improve the reception of the wireless network card?
