Can't turn on WiFi - Intel AC 9560

Post by Liran » 2020/05/13 07:37:27

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:
[ 5.112353] iwlwifi 0000:00:14.3: loaded firmware version 46.3cfab8da.0 op_mode iwlmvm
[ 5.219030] iwlwifi 0000:00:14.3: Detected Intel(R) Dual Band Wireless AC 9560, REV=0x318
[ 5.267451] iwlwifi 0000:00:14.3: base HW address: 4c:1d:96:05:98:1c
[ 5.523817] iwlwifi 0000:00:14.3 wlp0s20f3: renamed from wlan0

security boot disabled
rfkill:
ID TYPE DEVICE SOFT HARD
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 Intel® Wireless-AC 9560 from:
https://www.intel.com/content/www/us/en ... rking.html

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

Solution:
just blacklist ideapad_laptop kernel module and reboot

Code: Select all

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
