Answer 1

I would uninstall ITunes and your Ethernet controller/driver. Then re-install your ethernet driver useing your main board driver disk. then re-install ITunes.

Answer 2

You may have restored the system at a point where drivers for your wireless card were not installed.

2 steps:

1. Download drivers for your wireless card

2. Re-install iTunes
