[Nexus 7 Q&A, Help & Troubleshooting] Deleted member 4545050:
Greetings! New member here on the forum.

I just purchased a brand new Nexus 7 , 2012, the 16 GB variant.

It came with 4.1.2 installed. After booting it up, and trying to initially set it up, I noticed it would not connect to my home WiFi ( 2.4 Ghz, WPA2 AES, 8 char password ), as much as I would tap on it to do so. I quickly changed the Wi Fi by removing any security from it, no password whatsoever. After rebooting the router and the tablet, I tried connecting, and again, it would not do so.

I currently have connected on my home WiFi a Nexus 4, a Galaxy Nexus, a smart TV, and a laptop, which work well with it... why would this tablet not want to work, I can't understand.

Coming back to the tablet, I quickly set up a portable WiFi hotspot on my Nexus 4, and it managed to connect to it easily. After setting it up, I considered it was a fluke.

Enable developer settings, unlock bootloader, flash stock KRT16S 4.4 on it. After starting the tablet up, it would NOT want to connect to the WiFi, and I have no idea why, again, everything works with other devices.

This is a logcat while trying to connect:

Why is it not connecting? Am I doing something wrong, or should I return it as having broken WiFi and ask for a substitution? What can I do?
