Vista seems to have an annoying habit of creating several "Tunnel adapter Local Area Connection* ##" entries in my ipconfig results, which means I have to scroll up to see the actual entries I want to. That is a pain to do on a laptop with a touch pad, but also I think it was contributing to connectivity problems when switching between wireless and wired connections.
If you want to remove them, there is a method that seems to be harmless:
- Right-click My Computer, go to Manage.
- Go to Device Manager
- Click View on the top of the window, and check Show hidden devices.
- Now expand the Network adapters tree, and you should see several entries that start with isatap.(something).
- Disable (right-click, Disable) several of them, and verify that all your networking things still work.
- If that didn't cause any problems, you should be able to safely delete them (right-click, Uninstall).
Now your ipconfig readout should be a little more sane. This problems seems to be caused by IPv4 and IPv6 tunneling of some sort, which you can read about here.
