Windows 11: WiFi gone after sleep

Anonymous

My laptop is installed with Windows 11 Home Single Language and uses the network adapter of Realtek 8822CE Wireless LAN 802.11ac PCI-E NIC.

Every time when I put my laptop in sleep mode, the WiFi disconnected automatically, and the network adapter driver also disappeared from the list of device manager. After I restart my laptop, everything goes back to normal, but I would like to resolve this issue permanently.

I have updated the driver, but the issue still persists. Below are the images that illustrate the issue.

  1. WIFI has gone after sleep mode.

  1. When this issue happens, the WIFI icon also disappeared

  1. I run troubleshooting, it states that there is no proper network adapter driver installed

  1. The WIFI's network adapters driver disappear from the list of device manager when this issue happens.

  1. After I restart my computer, the WIFI connection back to normal, with the WIFI icon appearing and the driver appearing in the device manager.

HOWEVER, this issue comes back every time after, I put my laptop into sleep mode.

    Hi lch87.

    I'm David, and I'm happy to help you.

    When the adapter does not appear in Device Manager after sleep, do the following:

    1. Press "Windows + X" and select "Device Manager";
    2. Click on the "View" menu and select "Show hidden devices";
    3. Expand "Network adapters";
    4. If the Wi-Fi adapter is listed, right-click and select "Properties". Check if there is an error in "Device Status".

    I await your reply.

    Thanks for the clarification.

    It appears that the adapter is turned off when the computer goes to sleep but is not turned on when the computer wakes up from sleep.

    Send your system information.

    1. Press "Windows + R", type msinfo32 and press Enter.
    2. Select "File > Save" and save the file in a location you can easily find;
    3. Upload the file to the cloud (OneDrive, Google Drive, Dropbox, etc...) and choose to share it to get the link;
    4. Post the link to the file here so it can be analyzed.

    Thanks for your suggestion. However, as you can see from below picture, there is no power management tab. If I am not mistaken, the feature of no power management tab is a common feature of Windows 11.
