I just got my Nexus 7 2012 model today. I unpacked it and powered ON the device. It showed me the GOOGLE screen, the color X screen, I then selected the Language and then it asked me to SELECT WifI. Now in order to connect to my modem I need the MAC ID of the device, that's how my modem is configured. And for some reason the Nexus stops at this screen. Can i bypass the nexus from selecting wifi? please help!!!
