Ath5k doesn't work anymore! SIOCSIFFLAGS: Resource temporarily unavailable

[Raybuntu]

Hi all,
My Wlan Adapter works great until today. First of all it doesn't connect to my network. I tried to reboot but after that it can't find any Network.

"lspci" gives me:
05:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

I had linux-backports-modules-intrepid installed and everything was fine!

"sudo ifconfig wlan0 up" gives me:
SIOCSIFFLAGS: Resource temporarily unavailable

I get the same Error when I try to start kismet or aircrack.

Please help me!

[Raybuntu (raybuntu)]

Ok I don't know why but after 10times restart and 1 complete shutdown it's now workin again :D
Ok This bug should be invalid!!

[sabujakash (avradip)]

Exactly same thing is happening with me...
1. at first i was not able to connect to a wireless network.
2. after restart wlan0 is not up anymore!!!

[sabujakash (avradip)]

3. After shutdown and boot everything goes to normal, but then when I try to do high volume transfer through wi-fi, like I was copying one 700 mb file from one windows share in lan speed was around 1MBps and suddenly everything goes boom.
So this bug is definitely reproducable, atleast in my box.

[schmeii (schmeii)]

I reopen the bug because I can reproduce it in Jaunty. It desapear after some restart, but consistenly reapear if I hit the WiFi button on my laptop. Hitting this button again doesn't solve it, and it can happen even if I don't touch that button.

I still have this Bug in Intrepid sometimes (1 or 2 times a month). There is only one Solution: Complete Shutdown! A restart doesn't work!

[Andy Whitcroft (apw)]

This sounds like a kernel bug so its either linux or linux-backport-modules depending which you are using, definatly not linux-meta.

[Andy Whitcroft (apw)]

Could those of you seeing this issue confirm whether you have linux-backports-modules installed. If not could you please try instlaling that and retest. Please report back here including which release you are testing on (Intrepid/Jaunty).

[Raybuntu (raybuntu)]

I confirm that on Intrepid this happens with "linux-backports-modules-intrepid"!

[dovik (dovik-martin)]

This append on a Samsung NC10 with Jaunty (BETA) without "linux-backports-modules-jaunty".

$ lspci | grep Wireless
02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

Restart, stop, start, again and again and ... nothing to do. Same problem as describe on this page.

Andy Whitcroft > after installing "linux-backports-modules-jaunty" then stop, then start my netbook, the problem is ... always here.

[Sebastian (sebastianhaselbeck)]

also affects Jaunty. Out of the blue, Wireless stops working

ifconfig wlan0 up

gives SCIOCSIFFLAGS Resource Temoporariy Unavailable

[Tim (timharrington7)]

My wireless connection works after a cold boot then stops working after a random amount of time. This problem is affecting me at least once a day. The only fix I've found is to do a complete shutdown then a subsequent cold boot. Strangely, simply restarting does not fix the problem.

DETAILS:

Ubuntu 9.04 Jaunty Jackalope on a Toshiba Satellite L305-S5945.

$ lshw -C network

       [snip]

It is immediately noticeable when it happens because the NetworkManager Applet 0.7.0.100 suddenly reports that it's trying to connect. After it fails to reconnect it reports that the connection is unavailable. It doesn't seem to matter whether I am using the wireless connection heavily or not. The problem occurs during various levels of wireless usage ranging from almost none (i.e. no windows open, laptop idling) to heavy usage (i.e. active downloads, multiple open connections, etc.).

First repair attempt:
$ sudo ifconfig wlan0 down
$ sudo ifconfig wlan0 up
SCIOCSIFFLAGS Resource Temporarily Unavailable

The problem persists when I remove and re-add the ath5k module then try again.
$ sudo modprobe -r ath5k
$ sudo modprobe ath5k
$ sudo ifconfig wlan0 down
$ sudo ifconfig wlan0 up
SCIOCSIFFLAGS Resource Temporarily Unavailable

One website (http://www.vidarholen.net/contents/linuxtips/) suggests that "SCIOCSIFFLAGS Resource Temporarily Unavailable" is caused by no IRQ being assigned to the device. The suggested solution is to disable "Plug-n-Play OS" in the BIOS. Unfortunately, my BIOS does not have this option so I cannot confirm if this works.

I do not have linux-backports-modules-jaunty installed. I will install it then update this thread if there are any resulting improvements.

[chuy_max (chuy-max)]

I also have the error: SCIOCSIFFLAGS Resource Temporarily Unavailable

I do not have any linux-backport package installed.

The driver used is alto ath5k.

[Tim (timharrington7)]

I installed linux-backports-modules-jaunty and have not had a problem since.

[Someone in time (stevengm77)]

I just found it... I have Karmic on my laptop, and when I start to run a command related with aircraft-ng got the same error message:
airodump-ng mon0
ioctl(SIOCSIFFLAGS) failed: Unknown error 132
...and I have a Toshiba Satellite L25, my ethernet card is an Atheros AR2413, and it's the same ath5k...
I hope someone could find the solution...

[LukeQuake (luke-lukepotter-deactivatedaccount)]

Has anyone found a workaround and/or solution to this yet?

[Tim (timharrington7)]

LukeQuake: install linux-backports-modules-jaunty (i.e. sudo apt-get linux-backports-modules-jaunty). This fixed the problem for me

[LukeQuake (luke-lukepotter-deactivatedaccount)]

Thanks :-)

[LukeQuake (luke-lukepotter-deactivatedaccount)]

I've tried various combination of your post but can't find that package chief. Is there a typo in the command somewhere? (apart from install not being there).

same problem on Lucid beta 2 (without linux-backports-modules ) with ath5k on atheros AR5001.
It's exactly the same problem Tim reported on #13 (cold reboot ...)

lspci | grep Wireless

Is there a workaround for Lucid ?

[nowardev (nowardev)]

yes there is.... i have tested on 9.04 9.10 and 10.04 and it works :D on my atheros....

look here i have used the trick and not madwifi ....

http://nowardev.wordpress.com/2009/05/06/kubuntu-904-atheros-communications-inc-ar242x-80211abg-wireless-pci-express-adapter-rev-01/

basically you have to consume the residual voltage ..... to do this

-turn off your pc
-disconnect the plug :now your pc can't be turned on but there are some residual voltage (i guess)
-now press the computer’s button (which should turn on your computer i guess this should consume residual voltage)
-now plugin voltage
-start your pc :) and your silly atheros should work again with ath5k.

another way check if your atheros is supported by madwifi and download and compile them like i have written on my blog.

[roman.rene (roman-rene)]

Apparenly, the probleme seems to be network manager; i installed widc, removed network manager and it's working like a charm....

[nowardev (nowardev)]

i am on natty right now and i have the same problem here ...

running

rfkill list

i got

0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

doing

sudo rfkill unblock all

i got nothing because redoing

sudo rfkill list i got the same :

0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

and noway rebooting...
