WiFi stopped functioning after updating system

Hi,

Maybe someone can help thinking what could be wrong?

Tried:

Any idea what this could cause my WiFi not to function?

(Reason: 3=DEAUTH_LEAVING) seems to be a general message

Any other strange things?

Have looked through my pacman-log and saw these were updated:

[2014-10-29 09:19] [PACMAN] upgraded wpa_supplicant (2.2-2 -> 2.3-1)
[2014-10-29 09:18] [PACMAN] upgraded iproute2 (3.15.0-1 -> 3.17.0-1)
[2014-10-29 09:18] [PACMAN] upgraded iw (3.14-1 -> 3.17-1)

Maybe?

Re: WiFi stopped functioning after updating system

Have you found any solution to this? I have exact same problem with same network controller.

Re: WiFi stopped functioning after updating system

Not yet, I mentioned to get it working with an extra Alfa Networks USB adapter. Also it works when using a hotspot without WPA/WEP key / encryption.
Still need to have a look at it, had to go on vacation last week. Maybe someone else?

Re: WiFi stopped functioning after updating system

Hi, I have the same problem after a recent update. I also searched the internet for several hours but didnt find anything
Maybe a driverproblem?

$ wpa_supplicant -i wlp2s0 -c <(wpa_passphrase comeet ***********)
Successfully initialized wpa_supplicant
wlp2s0: Failed to initialize driver interface

I hope someone can solve this.

Re: WiFi stopped functioning after updating system

I've finally get wifi to work by stopping NetworkManager and using netctl for connecting.

Re: WiFi stopped functioning after updating system

Hey
Also no succes with netctl.
I hope there will be a kernel/firmware update in the near future that will fix this

Re: WiFi stopped functioning after updating system

Hi
I just want to let you know that I fixed my problem.
I disabled the systemd dhcpd.service and enabled a dhcpcd.service specific for my wireless interface. (so dhcpcd@wlp2s0.service in my case)

I hope it also aplies to your problem.

Re: WiFi stopped functioning after updating system

Have you tried going down your list above and downgrading to their previous stable version?  You might be able to isolate your problem that way.  You don't have to worry about iw, but the other two maybe.

Re: WiFi stopped functioning after updating system

Interesting... I started not being able to connect to my home network (WPA2) just today, and can confirm that disabling dhcpcd.service and enabling dhcpcd@wlo1.service works. I also tried downgrading to wpa_supplicant 2.2-2 and iproute 2.3.15.0-1 from ARM, as well as with linux 3.17.1-1 and 3.16.4-1 with no success per this possibly related thread.

I don't have time right now, but could post the journalctl/dmesg output of using dhcpcd.service and the interface-specific one tomorrow if that would be helpful.

Out of curiosity, can I swap them out without a reboot? I stopped dhcpcd@wlo1.service, started dhcpcd.service to verify lack of connectivity, and then wanted to go back so I could have an internet connection... but systemctl failed to start dhcpcd@wlo1.service. Are there other services I need to stop in order to do this?

I also noted this in journalctl, which I was prompted to search after getting some similar complaints when trying to futz with wpa_supplicant manually:

Not sure if that's relevant... but it's there and seemed worth posting.

Edit: Oh, I wanted to add that I can connect to my router with my phone, and can connect my computer to my phone via tethering... so my router isn't necessarily the issue, and I can connect to at least a network with the computer, so my card/setup itself shouldn't necessarily be the issue... just can't connect to my home router for some reason. Possibly a particular encryption protocol causing the issue (then again, just checked and both phone is using WPA2 PSK and my router says WPA/WPA2 PSK).

Re: WiFi stopped functioning after updating system

May it be a slightly different cryptography by the router ?

Re: WiFi stopped functioning after updating system

@TheSaint: definitely possible, though I'm more interested in why dhcpcd.service vs. dhcpcd@interface.service would matter if that's the issue at stake?
