My laptop (IBM Lenovo Thinkpad T410) has suddenly stopped connecting to any wifi network from Manjaro. I have tried installing and running different kernels and none of them work.
I was able to connect to networks by using wpa_supplicant manually, but not NetworkManager and nm-applet. However, with cable works well.
The same laptop running Windows works well and I also installed a fresh new Manjaro on a Dell XPS M1330 and I am having the same issue. I have other laptops running the latest Arch that work well. The problem seems to be restricted to Manjaro only on two different devices.
Can you please help me troubleshoot this? I had a look at journalctl for the NM unit and I couldn’t see any particular error, but I can share the logs for both laptops.
