    8821ce latency high on battery


    Howdy all, first post - new member.

    New-ish laptop, HP Ryzen 2500u - Vega 8, goes good in most ways.

    Only real problem is high latency on wifi when on battery.
    The wifi card is a Realtek 8821CE, of which there appears to be known problems of all kinds.

    Initially the unit had the OEM OS (10 home), which I ditched soon after purchase.
    I actually tried ramming 8x on it but couldn't get video drivers working (surprise surprise).

    Then did a fresh install of 10 home and the problem still persisted.
    I have since installed 10 LTSC and still have the problem.

    I have tried all the drivers as they're released since the beginning of the year, currently on 2024.0.9.103.
    Initially the unit had connection issues and along the way one of the drivers sorted that issue, however the high latency is not gone.

    I've also tried various power plan configs (currently on ultimate), and various other different drivers for other items, and countless other tweaks found all over the interweb.

    I've even spoken to HP support a few times, and they hit a brick wall and insist I send it in for service.
    I don't wish to do that at this point, maybe not at all.

    The ONLY thing which has made a difference, and which is a band-aid approach at best, is to disable "Microsoft ACPI-compliant control method battery" in device manager.
    This sorts the high latency problem, however it takes away the battery level meter.
    Not really a major issue as such, but an annoyance.

    The HP tech maintained it must be a hardware issue given the above description, however I can't see how given that it can be sorted (sort of) by disabling ACPI blah blah blah.

    I've hit a brick wall with this and still feel it's a driver issue of the wifi card, but am obviously not certain.
    Otherwise the laptop operates very well, but this puts a damper on it somewhat.

    The machine is generally up to date with the important drivers, has shutup 10, WUB, and a few other things to streamline this hobbled OS.

    Any ideas?

    :)

    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??

  3. 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.
