I have a Dell E5540. I recently set up docking after having the dock for over a year. The issue I am having is that when the laptop is docked my wireless connection goes to almost nothing. Less than half a Meg. 

When I pull it out of the dock the wireless jumps to normal. Reading on this issue I found a "workaround". If I open the lid on the laptop while its docked my wireless is normal...close it..and its back to zilch. 

I would think this is a setting somewhere but, so far, nothing is working. 

Any ideas?

Thanks
