http://forum.xda-developers.com – Hi, I'm using a USB key to connect to the internet, and usually If I want Wifi I set my computer as an hotspot -using internal windows options- but the problem is, my nexus 7 can't identify any of it. It simply doesn't show up. How to solve this problem? I'm on windows 7 64 bits. Thanks (HowTos)
