[Nexus 7 General] syslogic:
WiFi driver and/or profile ****sup

I noticed that every time it crashes it takes ages until the WiFi comes back, longer then after a reboot.

Once I seen it that the was a dupe network added and it didn't connect the default network.

The reboots might be caused by ConnectivityService which is crashing ActivityManager:
