This error removes my wlan0 interface from the enumeration list of network interface output from `ip link`
Can you please help me with this error? I have tried removing all of the firmware files in /lib/firmware and reinstalling linux-firmware.
The wifi works for a little bit until it crashes. Does anyone have a fix?

Same hardware, same error (although I'm using Manjaro, I thought it's worth commenting because the similarity to this post is striking).

Can anyone help? Thanks a lot!

Seems to have been a hardware problem: Since replacing the wireless card (Intel 7260) a few days ago, the issue has not occurred again.
