No wifi after Elementary OS Horus update om my CSL Panther Tab HD

Hello,

I don't know if my query is correct. I tried the google translator.
Unfortunately, my English is dusty - excuse me

There was an operating system update yesterday.
I am now at kernel version 5.19.0-32 generic.

Something has also happened with the firmware updates.
The two additional icons have disappeared again today.
But now my WLAN has disappeared - no networks are displayed,
I can no longer access the WEB.
With network settings you can only choose one VPN network
or configure a proxy access.

I ask for help.

kind regards
Gert
