    The wifi finally works now.
    I have been stuck on this for a long time now and without your help it would not have been possible.
    Really appreciate your fast and accurate replies.

    Awesome! Glad it's working. Please use thread tools at the top to mark Solved.

    NOTE TO SEARCHERS

    This thread is a very good example of the problems created when a new user reads some random forum post and installs a driver, only to find that it doesn’t work and so, after reading another forum, installs another driver that also doesn’t work.

    In this case, as in many, the newly installed driver installs its own slightly modified version of the common helper modules cfg80211 and/or mac80211 which conflict with the versions already installed.

    It will never help to install an Intel driver or a Broadcom driver or a Realtek driver for your Atheros wireless chip.

    Always be certain that you are installing the correct driver for your device. First, identify it. If it is an internal, PCI device, run:

    Code:
    lspci -nnk | grep 0280 -A3
    Or if it is USB:

    Code:
    lsusb
    An eight digit identifier will be listed like the above:

    Code:
    Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)
    Search with Google or similar for the identifier, in this example, 168c:003e. You will find that the driver is ath10k_pci and is already built in to all modern kernel versions.

    The process for USB is very similar.

    You can often find references to the correct driver here and at askubuntu.com.

    Please save yourself (and me!) trouble and be sure what you have before you install another incorrect, non-working driver.
