    Dell QCA6174 802.11ac Wireless - Wifi randomly disconnects

    Hi, I have a Dell Inspiron 7472 and installed Ubuntu 18.04 on it. Since I started using, the wifi randomly disconnects and the network widget stops working. I've already changed the firmware to the new version on github and set the power management to 2. Didn't work. There is also another thing going on with this notebook. The special keys when I press them after a while not using, there is a delay. I'm not sure if it's related to the installation, I already reboot the OS and nothing changed. Here is the paste from the wireless script. Thanks!

    Ref: line 506 country 00: DFS-UNSET

    You need to set your country code. If you really are in America/Recife, determine what the country code is by looking in /usr/share/zoneinfo/zone.tab
    Code:
    cat  /usr/share/zoneinfo/zone.tab | grep Recife
    To set the country code temporarily,
    Code:
    sudo iw reg set BR
    To set it permanently, you need to edit the file, crda
    Code:
    sudo nano /etc/default/crda
    On the last line, change it to read REGDOMAIN=BR (If you really live in America/Recife)
    Save the file and exit.

    If this doesn't address your issue then you will have to wait on someone with greater depth of knowledge than myself.

    [BUMP TOPIC]
    I have the same problem with Qualcomm Atheros QCA6174 on Acer Aspire V15 laptop.

    A great request for help. You can't work. Even I can't the Ubuntu updates download or some soft because the wifi disconnects.

    Here is my wireless-info.txt: http://pastebin.ubuntu.com/p/7VkM8bwKW2/plain/

    I use: Ubuntu 18.04.3 LTS
    kernel: Linux 4.15.0-62-generic

    Any ideas?
