    iwlwifi weak signal for Intel AC 9462

    I have problems with the integrated Wifi card, on a 'chuwi herobox'

    Wireless signal may be 90% on windows and 30% on Linux using the same machine and location.
    It is unusable because of the disconnections and the speed.

    I don't know how to solve it, tried every tutorial about similar problems without success.

    Here is some information, in case someone can help me.

    (I am using on USB Wifi module to connect, due the problems with the integrated AC 9462 card. Ignore that USB Wifi NIC from the information)

    Kernel version (from /proc/version):

    Linux version 5.8.0-29-generic (buildd@lgw01-amd64-055) (gcc (Ubuntu 10.2.0-13ubuntu1) 10.2.0, GNU ld (GNU Binutils for Ubuntu) 2.35.1) #31-Ubuntu SMP Fri Nov 6 12:37:59 UTC 2020

    This is the network interface I am having problems with:

    And some information about the system:

    Re: iwlwifi weak signal for Intel AC 9462

    We see this clue in your dmesg:

    Conflict between TLV & NVM regarding enabling LAR (TLV = enabled NVM =disabled)
    I suggested that you try a driver parameter:

    Code:
    sudo modprobe -r iwlwifi && sudo modprobe iwlwifi lar_disable=Y
    If seems to have solved the issue, then I suggest that you make it permanent:

    Code:
    sudo -i
    echo "options iwlwifi lar_disable=Y"  >>  /etc/modprobe.d/iwlwifi.conf
    exit
    Please post back your success.

    Re: iwlwifi weak signal for Intel AC 9462

    No, it does not work. Also tried combinations of:

    11n_disable=1
    power_save=0
    bt_coex_active=0
    swcrypto=1

    Without success
