Hi
I am using Intel 7260 HMW module with Jetson TK1. After doing all the recommended steps the wifi started working but it only works on some boot-ups and other times it doesn’t work.
This is the dmesg output when it doesnt work:

I am using this on a quadcopter and want the communication to be reliable. Any help is greatly appreciated.
Thanks
