since midnight my Nexus 7 2013 is not connecting via Wifi anymore. Wifi icon is grey and I see a fraction of all the Wifi networks around here. Sometimes my home network, sometimes not. Even when I stand directly beside my router. In the same time all my other Android devices are connecting well. I tried to set up an AP with my HTC One - same issue here.
Turning off and on NFC or switching the time automatic settings did not make it better - I read on Google that this might help.
When I try to restart the tab I get a connection like 10 seconds - then I am offline again. These are the only 10 seconds where the Internet is working on the tab.
I am running on 4.4.2 stock kernel and did not do anything to the configuration. It worked perfectly for months.
Has anybody an idea? Otherwise I will have to send it back to AMZN.
Thank you for your help!
