    /etc/modprobe.d/iwlwifi.conf delete the option "11n_disable=1".

    reboot system and look at the network detail in control center

    my network rate is 800+ mbps in 5G wifi chanel

    I did that as well already including ensuring I have full power with disabled power management. My iwlwifi.conf content is as follows.

    1. options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1

    /etc/modprobe.d/iwlwifi.conf delete the option "11n_disable=1".

    reboot system and look at the netwo ...

    Finally that did the trick. I posted all the other details as well. Appreciate the help.
