Jackityan,
did you ever get an answer to this or figure it out? I have the same problem. I tried ipconfig /all and I don't get any IP addr data. I checked the device manager and everything looks OK. I've rebooted a few times, run AdAware but still no IP info when I use ipconfig command. I have no idea where this executable is, so I don't know the path.

If anyone can help, it would be much appreciated, thx
