Really disabling a network connection in Windows XP

This new laptop of mine rather unsurprisingly has an ethernet connector coming out of it. However, I'm using wireless all of the time and trying to figure out how to actually disable the wired connection.

Currently, I have the card disabled in the hardware settings, have the network connection disabled, and have it set not to notify me about connectivity problems or show anything in the taskbar.

Nevertheless, somehow the card likes to reenable itself and complain about not being connected at random intervals. Any suggestions how to disable this thing? Do I need to dig into the BIOS or something (which I'd like to avoid since that is more annoying to reenable if I need a wired connection at some point)


Everything I could think to suggest you've already tried. I've never heard or seen of a computer that ignored all that stuff.
