@Renato_A glad you found a solution.
General information for all OpenMandriva users. wifi drivers are generally kernel modules these days. You can find what your current kernel has available by opening Konsole and running this command:
$ ls -lh /lib/modules/$(uname -r)/kernel/drivers/net/wireless
And sometimes you do need to “look around” for instance in this case for Realtek the various drivers are in as I recall 4 different sub-directories.
If you don’t see your driver listed then it is time to do internet search for “Linux <My_Wifi_driver>”. And in that case of course you will have to install it yourself as @Renato_A did here.
