Win2k SP2 should be fine for a repair. I'm not 100% sure but I don't think that you're asked for the key during a repair (been a while since I done one). I think that it's only Win98 keys that are not highlighted with the OS type and that Win2k would have Windows 2000 Professional, or similar under/over the key - Knawes/Countess_Vlad should be able to clarify. The barcodenumber alongside the key may give a clue (Google?)

Wireless networking is often a real PITA - in some cases you need to install a different method of connectivity. If you do a sudo lspci it should identify the wireless adapter (Network Controller). That'll be a good starting point.

Thank you a lot!

The information is of greate help to me.
