Bleeding on the cutting edge. Guess the 7 is too new, cause the online help when Googling for hints is so thin. I bought the 7 and furnished my Google account info. When the 7 arrived, my wireless router would not accept my password, due to MAC address filtering. I finally got logged in to the router's control panel, turned off the filtering, and it all then worked. But I wanted to turn the MAC filtering, and to do so I needed the 7's MAC address. I still don't know where to find it on the 7, but because I was still logged in without filtering enabled, I was able to use Cisco Network Magic to discover the MAC address of the new, unidentified item in my home wireless network. I wrote down that number, re-enabled the filtering, added the MAC address to the list of permitted addresses, saved it, and now I am happier (and connected). Two thumbs down to Google - they're as bad as Microsoft ever has been.
