[SOLVED] Connection problems on Atheros AR5001X+

Hi all. I've been having trouble with my internet connection. I think it happened after the last kernel upgrade.
I am using wicd and starting it with X. When I log in I get no connection at all and a message saying "No wireless networks found".
Rescanning makes no difference.
The weird part is that connecting the cable gives me an entry for the wired network and rescanning makes all available wireless networks appear as they should.
I connect to my wireless network and then disconnect the cable and then everything is fine.
Usually anyways. Sometimes I get a "bad password" error.
Everything worked perfectly until a couple of days ago and I would like to avoid a kernel downgrade, since I've never done that before.
Another weird thing is that if I just connect my ethernet cable it doesn't connect automatically, even though that worked even before I installed X and wicd.
I've read this post https://bbs.archlinux.org/viewtopic.php?id=115136, but it didn't help much.

Some info:

The Wicd properties window of my wireless network.
wicd

iwconfig when I boot

lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bg  ESSID:off/any

          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

and iwconfig after I connect to the wireless network using the cable

lo        no wireless extensions.

eth0      no wireless extensions.

What I have tried: Using my normal ip instead of static, starting dhcpcd on boot as a daemon, using netcfg instead of wicd.

When I run this

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

I get disconnected from the network.

And when I when I run this

dhcpcd wlan0

I get a timeout error.

That's all the info I can think of right now. And the router is probably fine cause my windows partition and a macbook don't seem to be affected.

Re: [SOLVED] Connection problems on Atheros AR5001X+

Iwconfig at boot shows your network card, you might need to run "ifconfig wlan0 up" to turn it on before running wpa_supplicant. Try wpa_supplicant without the -B(ackground) switch to see at which point it throws an error.

Re: [SOLVED] Connection problems on Atheros AR5001X+

I ran "sudo ifconfig wlan0 up" and then the same wpa supplicant line as above without the "-B" and I got this.

wpa_supplicant -Dwext -i wlan0 -c /etc/wpa_supplicant.conf 
ioctl[SIOCSIWSCAN]: Device or resource busy
Failed to initiate AP scan.
ioctl[SIOCSIWSCAN]: Device or resource busy
Failed to initiate AP scan.

Then it just left me with a blinking cursor for a couple of minutes until I rebooted.
Funnily enough, half the times I booted since the first post, the network was detected automatically, but only after about 30 seconds after openbox was started...

Maybe related to this thread? https://bbs.archlinux.org/viewtopic.php?id=116955

If so, you're suffering from this bug: https://bugzilla.kernel.org/show_bug.cgi?id=31452#c19

Re: [SOLVED] Connection problems on Atheros AR5001X+

It's not exactly the same, but I have noticed that many people have been having different kinds of trouble across different distributions with ath5k and ath9k since the last kernel upgrade. I guess the best approach (the one involving the least hassle on my part) would be to stay wired and wait for an upgrade to come along. Thanks for the replies both of you.

hmmm, I noticed you don't have network set in your daemons?

Anyways, hope it helps in any way.

Re: [SOLVED] Connection problems on Atheros AR5001X+

Thanks for the tip. As far as I understand, the network daemon isn't needed if I have wicd on that list.
Even if that's wrong, it worked flawlessly for about a year now without it.
I un-wired my connection to try your sugestion and noticed that it works now.
Would I have to blacklist the ath5k module to try out if the compat-wireless works better?
It still takes wicd 15-20 seconds to connect after X has started and that goes for both ethernet and wireless.
That's not that bad really and I can live with it, but an improvement is always welcome.

Nah you shouldn't I don't think for scanning/connecting to AP's etc. But if you want to use the aircrack-ng suite then yes.

About the network daemon, I just started using wicd today since I switched to Openbox/non DE recently. Guess it works either way tongue.

So what did you end up changing? The details in rc.conf?

Glad it helped!

Re: [SOLVED] Connection problems on Atheros AR5001X+

I actually didn't change anything. I had ethernet connected for a few days now and hadn't realized it worked. smile
I added "network" to the daemons just to see if it makes any difference and deleted when I realized it didn't.
I did however just install compat-wireless-patched and it's much better. Connects to wireless pretty much instantly.
Thanks again!

Nice, yeah with the stock drivers I noticed poor signals/connectivity and dhcp taking ages as well. I was also having software/driver meshing issues (wicd/dhclient) until I installed the compat version. Anyway nice to know another person with the same driver/AP management tool. smile
