    Lightbulb Focal fossa - Will bluetooth/WIFI work together?

    A lot of people have that issue with a lot of distribution(Not only Kubuntu).
    When connecting to bluetooth the wifi doesn't work. Keep connected but "0 Bps" or very slow.

    But the KDE NEON has the best result.
    The interference is weak and both can work together.

    Could check it for focal fossa?

    I think bt_coex_active could be a clue.
    I cant change it. It is aways off on the kernell config.

    My wifi is 2.4Ghz

    Thanks!!!

    =======================================
    See KDE NEON kernel config:
    Terminal commands
    ls /boot/config-* OR cat /boot/config-`uname -r`

    Why not get a daily build of 20.04, put it on a USB stick and check it yourself?

    Testing a LiveUSB is the best way.
    A second way is to lsmod and check to see what driver is being used for your wifi chip. Mine is the ath9k driver.
    Then do

    modinfo ath9k

    but use your driver, not mine.
    In the list of "parm"'s you may see one or more related to allowing bt to work with the wifi:
    parm: btcoex_enable:Enable wifi-BT coexistence (int)
    parm: bt_ant_diversity:Enable WLAN/BT RX antenna diversity (int)
    If your list of parms does not contain any bluetooth settings then your wifi chip may not be compatible with bluetooth.

    I've just tested sending audio to a USB receiver attached to my stereo and at the same time doing a speed test over (5G) wifi.
    When the speed test changed from upload to download the music gave a little stutter but otherwise all worked fine.
    Results speed test: Up 38.5 Mbps, Down 39.1 Mbps

    Seconds later Skype crashed...
    Restarted it and no new problems.

    This is a Thinkpad W520.
