Hello,
I have no wifi anymore since the last few days (I can't remember
whether it was after an upgrade or not). It actually looks like my
wifi card has disappeared:
- NetworkManager shows nothing related to wifi (before that, when I
accidentally switch wifi off, it said that wifi was turned off);
- Following
https://wiki.archlinux.org/index.php/Wi … ver_status
I've tried
lspci -k | grep wifi
and got nothing. Also
ip link
reported nothing. And
dmesg | grep wifi
was empty.
I'm quite lame with wifi, so I might me missing something obvious, but
to me it looks like my wifi card has died (do such things happen?). How
can I know for sure if the problem comes from the hardware?
My computer is a Toshiba Satellite A665. As for the wifi card, I don't
know.
Best,
Paul

lspci | grep -i network
and then look through pacman's log to see what driver you installed and whether or not an update has impacted that.

Have you checked if it is switched off in BIOS? Opened up your computer - it could have become loose?

Any chance you would have accidentally hit the wifi on/off button? Obvious question, I know, but I have done it myself once or twice.

jasonwryan:
lspci | grep -i network
yields nothing. I couldn't find anything meaningful in pacman's log
either, but I remembered I have installed Arch on an external drive;
I've booted from it, and there is no wifi there either, even though
that installation was last upgraded more than six weeks ago (well
before my trouble began).
PaterSiul:
There is nothing related to wifi in the BIOS. (Isn't that strange
enough?)
tomk:
That was my first thought, but the on/off button does nothing, and
anyway in that case NetworkManager would tell me wifi is turned off by
hardware (rough translation from French).
Any other idea?
Thanks to all,
Paul

If it doesn't show up in `lspci` then the card is either disconnected or dead.
You could check by using a live version of a different distribution

So it seemed the card was either dead or disconnected. I wanted to get
at it but the screw is stripped and I couldn't remove it. So I
restarted the computer to try to find how to deal with a stripped
screw, and guess what? The wifi's back.
So the card must be either dying or disconnecting itself... or it just wanted
a few days off...
Thanks all,
Paul
