    High latency with wifi card RTL8821CE


    Hi

    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?

    1. Where did you obtain that driver
    currently the driver of 8821CE is 2024.0.10.209
    from please, as it appears to be the wrong driver.

    2. You should it appears have
    Realtek Semiconductor Corp. - Net - 2024.0.8.113

    2024.0.8.113
    2.7 MB

    3. IMHO you need this driver = as above here is where t get it from
    https://www.catalog.update.microsoft...+Wireless+LAN+

    top one on the catalogue = click download on right of entry
    a window will open select the entry then click the arrow to the side of save
    select save as
    save to desktop
    then open the saved file and extract all to the same place.
    DO NOT install it yet


    4. Go to device manager
    expand network adapters right click the Realtek
    click uninstall device
    ON THE SMALL window that opens click to check uninstall driver software.


    5. NOTE shut down FULLY
    Option 1: Perform a full shutdown using Shift key
    Step 1: Open Start menu, select Power button.
    Step 2: Press and hold the Shift key on keyboard, while clicking on Shut down, and then release the Shift key to perform a full shutdown.

    6. Reboot with USB wireless in
    installing device MAY appear for the Realtek in the notifications area
    Go to device manager
    when it shows it will likely have a yellow warning marker and if you open it no driver
    right click it click install or /update driver if install is not available
    Select Browse my computer for driver software, and point to the location where you’ve extracted the Realtek drivers, and update it.


    Then try again and see if the problem is resolved.

    I found the driver on the webpage HP (https://support.hp.com/gb-en/drivers...model/23086201).

    The driver you adviced me is for the 8822CE version. Is it ok for 8821CE?

    I am a little suspicious of that driver on the HP website
    Type:
    Driver-Network
    Version:
    2024.0.10.209 Rev.S
    Operating systems:
    Windows 10 version 1909 (64-bit)
    Release date:
    Dec 6, 2019
    File name:

    Description:
    This package contains the DCHU driver installation package for the Realtek RTL8188EE, RTL8723BE, RTL8723DE, RTL8821CE, RTL8822BE and RTL8822CE wireless LAN Controller in the supported notebook and desktop models running a supported Windows 10 or Windows 10 Cloud operating system.

    You will notice that it is a DCHU package
    https://docs.microsoft.com/en-us/win...versal-drivers

    You will also see that the package of drivers includes not only your 8821 but also the 8822

    My research shows that there have been many reported problems with that driver that you have installed.
    I have seem quite a few reports of problems with these multi packaged drivers.
    I believe the one I sent you will work and MAY solve your problem

    If there are problems with it, you may go as below

    Thanks so much. The 2024.0.10.209 driver created buzzing/popping audio. Now I have installed 2024.0.8.113 that I hope won't create audio problems.

    1. Cheers

    2. These things are a little trial and error situation
    The 2024.0.10.209 is I thought the driver you had when you posted the topic
    but I did not see mention of popping audio on your post

    3. If the 2024.0.8.113 does not solve it or produces other adverse effects please try the

    https://www.catalog.update.microsoft....aspx?q=8821CE
    Version: 2024.0.8.116
    Company: Realtek Semiconductor Corp
    Driver Manufacturer: Realtek Semiconductor Corp.

    Version Date: 12/15/2019

    I sent you.

    4. If that does not solve the problem - please leave it installed but try changing power settings for the wireless adapter

    https://support.hp.com/gb-en/document/c04752217

    set Max performance
    as you report that it is OK on mains per - explore options for settings on battery - if sperate setting is not available for battery - then set whatever is available within your plan for MAX

    Unfortunately, buzzing audio and latency in ndis.sys continues. I found a post from a user who has a problem similar to mine (8821ce latency high on battery). At this point, I believe it is an incompatibility between RTL8821CE and acpi.sys that I hope will be solved in Windows or Realtek updates.

    Perhaps that is the only way forward
    If you have tried the suggestions in the other topic you found, perhaps it is worth having a look at Task Manager
    Press CTRL+ALT+DELETE to open Task manager - processes
    Set it to monitor top CPU cycles by clicking CPU heading so that high use is at the top and the small arrow aside the CPU heading is point down
    Playback audio and see which process spikes when the buzzing/popping occurs.

    I read that on some laptops the problem can be caused if the case has been opened for some reason and an antennae lead from the wireless adapter has been moved on its swivel connection, to a different angle, then allowing it to transmit interference to the sound. -

    Good luck with it. Sorry I could not find you the solution.
    Best wishes in the current crisis.
