    Re: WIFI is so slow with Ubuntu 20.04.2 LTS in notebook HP

    It appears that you have thrown everything that is suggested in various forums at this problem. Most of them are incorrect. First:

    [/etc/modprobe.d/rtl8723de.conf]
    options rtl8723de ant_sel=1
    You are not using the driver rtl8723de. Let’s remove the file:

    Code:
    sudo rm /etc/modprobe.d/rtl8723de.conf
    Next:

    [/etc/modprobe.d/rtw_8723de.conf]
    options DRIVER 11n_disable=1?
    This is meaningless; let’s remove it:

    Code:
    sudo rm /etc/modprobe.d/rtw_8723de.conf
    Next:

    [/etc/modprobe.d/rtw88_8723de.conf]
    options rtw88_8723de 11n_disable=1?
    The driver has no such manipulable parameter; let’s remove it:

    Code:
    sudo rm etcmodprobe.d/rtw88_8723de.conf
    Now:

    libkmod: ERROR ../libkmod/libkmod-config.c:716 conf_files_filter_out: Directories inside directories are not supported: /etc/modprobe.d/50-rtl8723de.conf
    You are not using the driver rtl8723de. Let’s remove the file:

    Code:
    sudo rm /etc/modprobe.d/50-rtl8723de.conf
    You have two possibly conflicting drivers installed.

    ##### lsmod #############################

    8723de 1695744 0
    rtw88_8723de 16384 0
    Let’s blacklist one and see if the performance improves:

    Code:
    sudo -i
    echo “blacklist rtw88_8723de”  >>  /etc/modprobe.d/blacklist.conf
    exit
    Reboot and tell us if there is any improvement.

    Let's change the blacklist:

    Code:
    sudo nano /etc/modprobe.d/blacklist.conf
    Change the line:

    Code:
    blacklist rtw88_8723de
    To read:

    Code:
    blacklist 8723de
    Save (Ctrl+o followed by Enter) and exit (Ctrl+x followed by Enter) the text editor. Reboot and tell us if there is any improvement. If there is none, please run and post a new wireless_info as you did above. Please be certain that you do not accidently post the old original.
