PostPosted: Thu Sep 02, 2010 4:15 pm    Post subject: [Solved] Atheros AR9285 Disabled (hp dv3 laptop) Reply with quote

I am a gentoo noob, this is my first installation. Have been using linux (ubuntu) for a year or so.

I have a HP laptop (Pavilion dv3-serie) with a Atheros AR9285 integrated wifi card. I have no network interface for that card (no wlan0 in ifconfig) and the card is shown "DISABLED" in lshw

My laptop has a enable/disable wifi toggle button with the LED in orange (orange = disabled, blue = enabled) but pushing the button does not help.

I have a 2.6.34 kernel and i have installed compat-wireless 2.6.35 and 2.6.36-rc2, with no luck.

Some commands:

#lspci
Code:

...
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
...


#lshw -C network
Code:

I think i have configured the kernell correctly

Thank you all.

howdy

check and see if the interface shows via

Code:

cat /proc/net/wireless


it should based on what you've posted above.

assuming it does, does anything useful get thrown to dmesg if you

Code:

ifconfig wlan0 up


?

Complete shot in the dark here. I have an AR928x, never run into this, so not sure what exactly is going on.

thank you! it was only the "ifconfig wlan0 up" i thought ifconfig listed every network interface (even if it was down), so when i didn't saw the interfaced listed i thought something was wrong, than you very much!

now everything is working, sorry for wasting your time

no worries, if you knew the answer you wouldn't ask, and if you don't know the answer asking isn't a waste of time at all :)

ifconfig shows everything that's up

ifconfig -a shows everything, up or down, provided the driver for the network device has loaded successfully, and should more or less match /proc/net/dev

-if someone's device isn't showing in /proc/net/dev (everything including wireless) or /proc/net/wireless (just wireless) I assume driver or firmware problem
-if it shows there, but not in ifconfig output, I assume they forgot the -a switch, or that they already have the driver bits taken care of, and now simply need to configure client-side tools (e.g. WICD - which i highly recommend)

Hi,

I also have an AR928x, but my device doesn't show in cat
Code:
/proc/net/wireless
. What kernel module or driver do you use?

Thanks,

ath9k is the driver for that series of atheros chipset

That's exactly what I'm trying, but I failed. Can you show me how you configure your kernel? Maybe you can give me your kernel.conf file?

@phunehehe: Is your card internal (pci) or external (usb)? Because the usb card has its own driver and needs firmware. If you have the driver as a module, have you checked that it and its dependencies are loaded?

Code:
% lsmod | grep ath
ath9k                  72204  0
ath9k_common            2441  1 ath9k
mac80211              147560  2 ath9k,ath9k_common
ath9k_hw              213857  2 ath9k,ath9k_common
ath                     8722  2 ath9k,ath9k_hw
cfg80211              139086  4 ath9k,ath9k_common,mac80211,ath

@mr.sande: mine is an internal card, and
Code:
lsmod | grep ath
gives the same modules that you listed. Do I need to enable them somewhere else?

If the drivers are loaded and your card still doesnt show up in ifconfig -a, then Im sorry to say I dont know what to do.

If its a problem with connecting Id try wicd, because its nice :)

Yes, my card does show up in ifconfig -a as wlan0. And when I try ifconfig wlan0 up it shows up in ifconfig as well.
Code:
wlan0     Link encap:Ethernet  HWaddr 00:22:43:61:a2:f0 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)


It shows up it /proc/net/dev too (with a bunch of zeros behind wlan0), and I don't have a file called /proc/net/wireless

However, I can't do iwlist wlan0 scanning, because iwlist says
Code:
wlan0     Interface doesn't support scanning.


I guess that's why wicd cannot detect any network. Any hope for me?

iwlist will not scan if the interface is down, do 'ifconfig wlan0 up' and see if it works. wicd is supposed to do that for you though.

I am still unable to make it work yet. Tried bringing the interface up before scanning but that doesn't work either.

phunehehe, I just went through the paces of getting my new AR9285 up and running with the ath9k driver. I was having issues the same issues you were: the answer was in the kernel config. I was playing around with options, recompiled a new kernel and presto, wpa_supplicant started working with the card. Here is my kernel config, hopefully you can mirror and get success. I'm using 2.6.34-gentoo-r12.
Code:

[*] Networking support  --->
 -*-   Wireless  --->
  <*>   cfg80211 - wireless configuration API                     
    [ ]     nl80211 testmode command                           
    [ ]     enable developer warnings                             
    [ ]     cfg80211 regulatory debugging                           
    [*]     enable powersave by default                           
    [ ]     cfg80211 DebugFS entries                               
    [*]     cfg80211 wireless extensions compatibility                 
    [*]   Wireless extensions sysfs files                           
   <*>   Common routines for IEEE802.11 drivers
    [ ]   lib80211 debugging messages                               
   <*>   Generic IEEE 802.11 Networking Stack (mac80211)           
            Default rate control algorithm (Minstrel)  --->           
     [ ]   Enable mac80211 mesh networking (pre-802.11s) support     
     -*-   Enable LED triggers                                     
     [ ]   Export mac80211 internals in DebugFS                     
     [ ]   Select mac80211 debugging features  --->

 Device Drivers  --->
[*] Network device support  --->
 [*]   Wireless LAN  --->
 <M>   Atheros Wireless Cards  --->
   [*]   Atheros wireless debugging                                 
  <  >   Atheros 5xxx wireless cards support                       
  <M>   Atheros 802.11n wireless cards support                     
   [*]     Atheros ath9k debugging                                 
  < >   Atheros AR9170 802.11n USB support 


Good luck!
