    LTS 14.04 Wifi Drops - Needs Reboot - Qualcomm Atheros QCA9565 / AR9565

    Hi,

    I have been facing this issue for last few weeks. I have tried many solutions but seems like no success.

    System:
    Dell Inspiron 3537
    Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)



    Problem:
    Wifi will suddenly drop saying You are Now Offline. Then It will try to reconnect, sometime WIFI will be greyed, sometime show no WIFI connections,
    will mostly fix on reboot, but will drop again within few minutes or sometime after several minutes... it keeps happening..
    In the start when it started to happen, pc will hang and take no input, had to reboot using the power button,.. after clean install that hanging issue has been very rare.


    Update: After clean ubuntu install i thought system hanging issue was gone, however as I am using with LAN cable for last few hours, it has been about three times,
    i have experinced this issue too i.e. my system will just freeze/hang, with no notification, nothing, cannot move cursor, or any input on the keyboard.. only can restart
    with the power button long press. (REISUB input command also dont not work, it just does not take any input, had to reboot with power button.. )

    Fixes I have tried:

    I have tried many fixes from the thread, it seemed like solution but after some time error will come back again..
    Tried:
    options ath9k nohwcrypt=1

    I have tried even Clean Install, I was happy that it would be resolved, but within an hour it start occuring.

    I have also installed backport (it was new for me but i followed along, but after reboot, issue started to happen again)
    I downloaded and installed backports-3.16-1 but no success.

    here is output of the script i read in guildeines thread to help me solve the wireless issue. Please help me fix this issue, it has been troubling me so much after clean ubuntu install that
    what could else be tried or fixed as it is impacting my laptop use so much, i have to use LAN wire most of the itme to get work done.

    Thanks so much for your time and help in this regard!
