solidworks 2010 lockup problem

Hope someone can help me with this situation - I have solidworks set up on my laptop and it works fine when I have it in my docking station with and running it with a second monitor.  The computer is directly connected to the network.

My issue is when I remove the laptop from the station and run it wirelessly doesn't matter whether it's a part or an assembly the program locks up.  What are possible fixes?  Have not tried to run wirelessly with dual display.

Running windows 7, 4gb ram, 64bit
