[SOLVED] Wi-Fi network device missing after update

Hi, I own a ThinkPad X201 on which I run arch, and after the latest pacman -Syu I found that I can't connect to my network, as ip and ifconfig only list the loopback device and the ethernet card, but not the Wi-Fi.

What happened? Thanks in advance!

Who knows.

If you post the full output of dmesg then it might provide clues to what is wrong.

Compare the version numbers reported by uname -a and pacman -Qi linux   (Assuming you are using the stock Arch Linux kernel)

I wager they are not the same.

Right; http://pastebin.ca/3624498

I suppose lines 756-761 are relevant?

I googled, but I was unable to find anything but an Arch Linux Forums post with 0 replies.

Compare the version numbers reported by uname -a and pacman -Qi linux   (Assuming you are using the stock Arch Linux kernel)

I wager they are not the same.

They actually seem to be:

╭─theon@bento ~  
╰─➤  uname -a
Linux bento 4.5.4-1-ARCH #1 SMP PREEMPT Wed May 11 22:21:28 CEST 2016 x86_64 GNU/Linux

╭─theon@bento ~  
╰─➤  LANG=C pacman -Qi linux

Version         : 4.5.4-1

They are, but they're out of date. Is this a partial update situation? What version of the linux-firmware package?

Huh, turned out I didn't even have linux-firmware installed. Installing it and finishing an indeed partial update solved this. Thank you!
