[Somehow Solved itself]Wifi not working on one machine anymore

gee · 2014-04-09 22:36:42

Hello,

My main machine had been working fine for a while, then I went on vacation in March and came back yesterday.
Since then I am unable to get that computer's wifi to connect to my router.
I have tried to downgrade packages that were updated up to one week before I left but no go...
I then did a full upgrade of my system, and still no go. (I'm on testing amd64).

My phone, tablet and other computers connect fine so not a router issue.

I have updated one of my other machine to latest and it still connects fine so I'm guessing the issue is either driver related, or config related.
I tried rolling back to 3.13.2 or even to 3.12.8 but still nothing...
I tried rolling back dhcpd, dhclient, wireless_tools, wpa_supplicant, nothing helped.

I'm using NetworkManager to connect to my router, with Personal WEP2, but same result with no security.
In the applet it just states "configuring interface" for a while before failing.
In journalctl I see this:

Apr 10 14:41:02 MACHINE NetworkManager[374]: <info> Activation (wlan0) Stage 2 of 5 (Device Configure) complete.
Apr 10 14:41:02 MACHINE NetworkManager[374]: <info> Config: set interface ap_scan to 1

Apr 10 14:41:09 MACHINE NetworkManager[374]: <info> (wlan0): supplicant interface state: authenticating -> disconnected

and in dmesg

[ 1492.353563] wlan0: direct probe to MACADDRESS (try 1/3)
[ 1492.556679] wlan0: direct probe to MACADDRESS (try 2/3)
[ 1492.759942] wlan0: direct probe to MACADDRESS (try 3/3)
[ 1492.963227] wlan0: authentication with MACADDRESS timed out

I quickly tried with wifi-menu but it was also failing.

I've been trying all I could think of but never a difference...
I'm currently using an RJ cable, and it works fine.

I'm in big need of help now

Thanks!

I am using ath9k driver, the card chipset is Qualcomm Atheros AR5416 Wireless Network Adapter.

I tried connecting manually, but no go:

iwconfig wlan0 essid MYESSID
=> nothing returns (I've removed the security as my key is not the correct length for iwconfig..)

dhclient wlan0
=> still nothing returned

iwconfig wlan0

Please don't bump your thread: https://wiki.archlinux.org/index.php/Fo … te#Bumping

Add some more relevant information, like your card/driver, and what happens when you try and connect manually...

gee · 2014-04-10 22:50:56

Alrighty changed, thanks!

I'm starting to wonder if the issue is the wireless card...
If it sees the network and everything, shouldn't that mean that it works?

You can try a lot of things

- Try to remake every configuration!
-Try another method to conect and set up a wifi conection (maybe disable networkmanager first) and remove any config of the network. You can try to do it mannualy or with another automated method, like wifi-menu, that is combined with netctl.

In this link https://wiki.archlinux.org/index.php/Wi … management, you will have sufficient information to set up and debug your wifi connection!

gee · 2014-04-10 23:26:36

Hi,

1- which conf? I can only think of NM's conf, but since I tried manually and wifi-menu with nogo I assume that's not it, what I am forgetting?
2- Like in 1- I already did.
3- I'll look again at this link, maybe I missed something in there, thank you!

henriqueleng · 2014-04-10 23:38:41

Sorry
My english is not good, and i cannot understand what do you said here

but since I tried manually and wifi-menu with nogo I assume that's not it, what I am forgetting?

I don't know if you trying to say that you tryed wifi menu and it doesn't worked, or its no the problem.

If could you write different, maybe i will understand.

Sorry for my poor english!

gee · 2014-04-10 23:50:25

Please don't apologize when you are here trying to help me

I tried wifi-menu and it didn't work either yes.

I just tried plugging a usb wifi stick from another machine into my troubled computer, and with that one it worked right away.
This is also using ath9k, but a different variant I believe, ath9k_htc.
So from that I assume the software is all good, maybe apart from the driver?
Or maybe the wifi card died during my vacation? that'd be weird.

henriqueleng · 2014-04-11 00:15:44

Yes you are right, software is ok. Its probaly driver / module problem.

Wath i recommend you is, first check you network adapter info and status.
Follow this steps: https://wiki.archlinux.org/index.php/Wi … ver_status to detect and check your hardware.

Once you do it, here https://wiki.archlinux.org/index.php/Wi … 2Ffirmware you have information about found the right driver for your device.

And for sure post your "lspci -k" output.

If you already did that and did not work I will not be able to help you more.

gee · 2014-04-11 00:32:28

lspci -k seems fine.

05:05.0 Network controller: Qualcomm Atheros AR5416 Wireless Network Adapter [AR5008 802.11(a)bgn] (rev 01)
        Subsystem: Qualcomm Atheros Device 3071
        Kernel driver in use: ath9k
        Kernel modules: ath9k

as for the firmware, the debian wiki says that ath9k does not need one to be installed, I have the linux-firmware package installed anyway...

I'll try a live usb distro to see if it works or not.

gee · 2014-04-11 01:40:36

Hmmmmmmmmmmmmmmmmmmmmmm a mystery just appeared:
I tried a different live distro, and it worked!
So the issue was setup/software related and not hardware related.
BUT, when I restarted into my standard arch, it worked as well... and I have no clue why!
Is it possible that somehow running the other distro unblocked something in the wifi card and that is why it works now?
I'm baffled here.
