I serached google a lot and tried installing linux-firmware, trying various kernels and other tricks; but nothing worked.

Any help will be appreciated.

Thanks

is fast boot (or something similar) disabled in bios - you may not have this option;
is fast startup disabled in windows;
and check a keyboard shortcut/or hardware switch for the wifi

3

fastboot wa enabled in both BIOS and windows.
Disabling it in both of those did not make any difference.

4

and this:

run this:
sudo modprobe iwlwifi
and see if it helped

nothing hzppens or displayed

 ~/Desktop  sudo modprobe iwlwifi

Any idea what following error means and how to resolve this:

try:

sudo modprobe wl

please open the package-manager, enable downloads from aur and install the package “iwlwifi-next”. it should contain the necessary files.
reboot and check.

should result in this:

so did you checked if the wifi is working after running the modprobe command?
and post output from:
inxi -N
after you run the modprobe command

No, wifi isn’t working. I think the drivers needs to be installed for Intel Alder Lake-P PCH CNVi WiFi driver - which I am not able to find.

   ~/Desktop  inxi -N                                                                                                                                                                                                                              1 ✘

switch to the 6.0 kernel - not the rc one - and check again with:
inxi -N

the drivers for your wifi are in kernel: iwlwifi, and they are being loaded, but there is something with the hardware, probably related to windows/bios

13

Thanks, I checked BIOS and windows. I cannot see anything that might be interfering with wifi. Wifi works fine in Windows.

I tried kernel 6.0.2-2, but that does not even load, get stuck with a blinking cursor.

Checked with Linux Mint live boot usb, the same problem there as well. No WiFi :frowning:

14

if mod-probe failed, which could mean the lack of support in kernel 5.15. a google search did find this result;

it seems fixed with kernel 5.17. since 5.17 is EOL now, recommend you using atleast 5.19 (since 6.0.x is not working for you)

15

do you have nvidia?

go to windows and disable hibernate and fast startup, and disable the wifi from device manager, shut down your pc - dont reboot, and check again the wifi in manjaro…

16

Yes, I have nvidia.

Funny thing is that wifi works good when I install Manjaro on a USB and boot from it. But, wifi does not work when I install Manjaro on SSD diskdrive and boot from there!
Kernel 5.19 works and no other kernel gets the wifi working at all
