    High latency with wifi card RTL8821CE


    Hi *Smile

    I have a problem with ndis.sys. When i use PC on battery, ndis.sys is too high and surely it is caused by wifi card (Realtek 8821CE) because if i insert a wifi USB adapter the latency is normal. Moreover, when i use PC plugged in, there aren't high latency. I also update driver (currently the driver of 8821CE is 2024.0.10.209) but the situation don't change. How can i solve this problem?

    8821ce latency high on battery

    HP 15-db0125au.

    I personally think it's a driver/ACPI issue.
    On AC it's perfecto, on DC it's terrible.

    Latency monitor points to the wifi card.

    My next step was to try an Intel equivalent card, but I'm not sure which one to grab.
    This one only has 1 antenna and as far as I'm aware I can use a dual antenna one but not use BT.

    Does that sound right?

    I don't use or need BT so...

    High Latency

    I'm having an issue with high latency. After a reboot the computer runs fine....but over time the latency continues to increase so eventually everything starts to respond so slow that it is unusable and have to do a hard restart. I haven't been able to
    figure it out. I bought an external network card to use instead of the onboard one hoping that would fix it....but same results. Anyone have any ideas??

    High DPC latency

    I use my Dell XPS for recording and live playback but the system suffers from high DPC latency caused by ACPI driver.

    I removed Dell audio drivers and installed those from RealTek with no avail. Latency is an issue because I need this computer for live recording. Please your advice.
