Hi,

Can you provide more details:
 - which kernel's version has a functioning WiFI connection?

Please attach here:
Results of: "lspcidrake -v" command.

Keywords: (none) => NEEDINFO
Component: Release (media or process) => RPM Packages

Reporter, could you please reply to the previous question? If you don't reply within two weeks from now, I will have to close this bug as OLD. Thank you.

5.9.11-3.mga8        
        + Revision: 1649783
        - update defconfigs
        - rtw88: enable 8821CE support
        - switch from 3rdparty rtl8723de to the in-tree rtw88_8723de driver
        - desktop586 config: enable NDSIWRAPPER
        - move r8822be module alias to correct module

Kernel 5.9.11-3.mga8 has been updated to add better support for this Ethernet card.
Please have a test on it.
Also, please note that same version is in M7 updates_testing repository.

The internet connection is good now, thank you.

Had to reopen, there are problems with the driver again.

Hi, what are the symptoms?
Mageia 8 does not recognize your card?
Normally as soon as a kernel has been set, it can't unset itself to recognize a peripheral.

Again can you add lspcidrake -b output only about your Realtek WiFi card, please?

Status: REOPENED => NEEDINFO
Keywords: NEEDINFO => (none)

The driver could not detect the Wi-Fi networks yesterday somehow, but now it can detect the closest router network.

The output of "lspcidrake -b" now is:
lspcidrake: invalid option -- 'b'
usage: lspcidrake [options]
        -p, --pci-file <file>   PCI devices source [/proc/bus/pci/devices by default]
        -u, --usb-file <file>   USB devices source  [/proc/bus/usb/devices by default]
        -v, --verbose           Verbose mode [print ids and sub-ids], implies full probe
        -d, --dmidecode <file>  To use this dmidecode output instead of calling demicode

Status: NEEDINFO => RESOLVED
Resolution: (none) => WORKSFORME
