Wifi Device Disappeared

Hi, I've been having this issue since I upgraded a few days ago. Not sure what to do next.

Re: Wifi Device Disappeared

What is the problem?  Just what is in the title?  What does disappeared mean (operationally defined)?  Does it not show up in the output from `ip a` or is it just no longer listed in some gui something-or-another?

What is the wireless hardware?  Chip ID, etc ...

Re: Wifi Device Disappeared

My wireless device is wlp3s0. When I use 'ip a' I don't see it there like it used to be. I don't think that it's broken or malfunctioning, but this issue began after upgrading.

Re: Wifi Device Disappeared

What my colleagues are saying is: is it a USB device, is it a PCI device?  Which one?

Post the output of lspci -nn  if it is a PCI device.

It is a PCI device.

Re: Wifi Device Disappeared

Unless I am missing something, the I don't see any wifi devices in that list.  That is a bit problematic.

Does Windows see it?  Can you see it if you boot from your Arch install media?

Re: Wifi Device Disappeared

I actually don't have Windows installed, nor do I have a CD. This is apart of why I was so confused about what to do next.

Re: Wifi Device Disappeared

I would try to lay my hands on something I can boot that would let you look at the bus devices.
You might try powering all the way down.  By this I mean removing line cords from towers or batteries from laptops after the shutdown.  Wait a bit, re-power and see if the device appears on the bus.

Is this a PCI-e?  Is it a laptop?

Edit:

Linux version 4.0.6-1-ck (squishy@ease)

You may want to try with the main line kernel if you still have it installed.

Re: Wifi Device Disappeared

Make sure the hardware is on (it could get disabled through some Fn key or a switch somewhere on the laptop).

Re: Wifi Device Disappeared

[Sidenote] I accidentally hit the report button.

As far as the switch, that's the first thing I checked.

Re: Wifi Device Disappeared

I'd install linux-lts and boot into that.

-edit-

If your PC is Dell Latitude E6520 (is it?), then it should have a WiFi switch on the right side. Double-check that it is in the "on" position.

And maybe there's something about WiFi in BIOS.

Re: Wifi Device Disappeared

I'm rebooting now to see if LTS has any effect. I double-checked the switch, but that had no effect.

Re: Wifi Device Disappeared

Update -- LTS didn't have any real effect on the issue. I did ip a in getty and got the same result.

Re: Wifi Device Disappeared

Again, the card is PCI, not USB. It used to work by default with the Kernel so I never actually noticed or paid attention to that information. Is there a specific command you'd like to see?

Re: Wifi Device Disappeared

I'd like to see the make of the card, the driver you have installed, and pacman's log for the update that changed things. Without that information, this thread is going nowhere...
