Basic Info
Laptop: Lenovo Y540
lspci: Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)
ip link: wlp0s20f3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
uname -a : Linux localhost.localdomain 4.18.0-147.el8.x86_64 #1 SMP Wed Dec 4 21:51:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Nothing special in dmesg:

security boot disabled
0 wlan ideapad_wlan unblocked blocked
1 bluetooth ideapad_bluetooth unblocked blocked
2 bluetooth hci0 unblocked unblocked
3 wlan phy0 unblocked unblocked

I have also copied to /lib/firmware the relevant files for IntelĀ® Wireless-AC 9560 from: ... rking.html

Still, I can't turn the WiFi on.
Any assistance will be much appreciated.

just blacklist ideapad_laptop kernel module and reboot

Code: Select all

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
and: ... ug/1837136
