Peter,

You can disable the network card that way it won't matter if it is connected
or not.

right click on my computer icon, click on properties
click on hardware tab
click on device manager
expand network adapters
right click on your network adapter and click on disable
it should refresh the screen automatically and you will see the network card
icon with a red X appear now.

That's all you need to disable the network.
Also if you plan to only do music, disable all the services that you really
don't need.
go to control panel, administative tools, services and check which ones
should you leave on automatic or put on manual.

hope this helps,
Rafael
