Hello,

I don’t really know since when (because i was mostly plugged), but i have no more wifi interface.
I am on Lenovo legion y540. I put some command outputs, if you need more don’t hesitate to ask.

$ ip l

I have already tried to put new iwlwifi-9000-pu-b0-jf-b0-34.ucode downloaded in /lib/firmware/ without success.

I have pretty much the same issue, using my Acer Aspire A515-41G-125M, low spec laptop, replaced wifi card for a new one - Intel Wireless AC 9260. Card works completely fine in Windows 10 - I have disabled fast boot and hibernation, since I’ve read this issue is mostly caused by this. It made no difference. Tried newer and older kernels. Also no difference. Your logs are almost identical to my terminal output. I literally have no idea what else should I try to fix it. Have you fixed it since the time you posted this ?

4

I already tried some other kernels. But how do you get 5.3 kernel ? (Apparently issue is not present there according to the post you mentioned.) I can’t seem to find it in pacman. Do I have to compile it myself ?

5

What kernels have you tried? 5.4 and 5.10 are LTS. Try those first. Also try 5.12. 5.3 is EOL not advisable as there will not be any security updates.

6

Unfortunately it doesn’t work in newer kernels. According to bugzilla URL you posted 5.3.13 shouldn’t have the issue. I don’t really want to install EOL kernel - I want to potentially use the laptop and using kernel without security updates doesn’t sound too good to me.
