Dell Laptop loses network connection or deactivated

This is a problem we found to be a funny yet really annoying default “power saving” method enabled on Dell D630 and D620 laptops with Broadcom NetXtreme 57xx Network chipsets.  There are many scenarios to this problem that may be misleading but basically if you are running on batteries and your Dell notebook ethernet network stops working then this is how to solve the problem.  (our scenario always has the user starting the notebook on battery or starting it with power adaptor and ethernet cable and then unplugging the ethernet and trying to go wireless then back to ethernet)

 
1) Open control panel Start –> Control Panel
2) Open the Internal NIC Configuration –> select the radial “Always active on Battery” then click apply.

NOTE: Once the network card is deactivated, you must connect the laptop back to an AC source to reactivate the internal network card.  Replugging the network cable without an AC source may not reactivate it.
