z3 wireless pairing problem

I have 2 windows 7 64bit with pretty much the latest updates. I was able to successfully pair the phone with one computer using the basic steps: connect USB - chose pair - right click on the phone icon in my computer - choose network configuration - and so on..

However, on the 2nd windows 7 pc, after USB is connected, I don't have the "network configuration" option showing after right clicked on the phone. What might be the problem? I tried reinstall the driver and still not working. File transfer via USB, ADB are all working fine.

Am I missing something?

thanks,
