Wired adapter is working well however wireless isn´t.

Others command executed:
iwlist scan
lo Interface doesn’t support scanning.

eth0 Interface doesn’t support scanning.

Hi
Is the kernel-firmware package installed? Is this a laptop by chance
(does it run windows), if so not a wireless hardware/Fn button switch?

Hi
Run the command;

zypper in kernel-firmware

Can I also see the output from;

/sbin/lspci -nnk |grep Network -A3

I also see;

I/O ports at d000 [disabled] [size=256]

No BIOS setting(s) to reset the interrupts or try a different PCI slot?

Also browse the output from dmesg or journalctl -x to see if anything
jumps out.
