I installed VM oracle on win7 enter laptop, when at office docked it works fine and I do my laptops OK. But I shutdown my laptop take home with me and turned on connected wireless home internet and launched VM and GNS3 try to open existing laptop or drag new IOU device to start. Devices are not initializing and getting red square box on devices " node not initialised" error message if I hover mouse on top on red error box.
I even wired my home internet and did not work. and next morning when come to office dock my laptop it works fine..

Why is this? I installed software while docked and at the office..
