No wireless networks detected in -current after upgrade of wpa_supplicant
Hi all,

I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.

I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue. Any nudge in the right direction would be much appreciated.

What do you see with 'ifconfig -a'?

wpa_supplicant shouldn't be a problem - it helps associate with networks, and has nothing to do with presenting actual networking interfaces.

As mentioned, does 'ifconfig -a' show your card? If not, what type of card / chipset is it ?

'ifconfig -a' produces the following:


root@darkstar:~# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:24:8C:50:87:39 
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::224:8cff:fe50:8739/64 Scope:Link
          RX packets:4624 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1231 errors:0 dropped:0 overruns:0 carrier:2
          collisions:0 txqueuelen:1000
          RX bytes:1213554 (1.1 Mb)  TX bytes:209990 (205.0 Kb)

lo        Link encap:Local Loopback 
          inet addr:  Mask:
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:480 (480.0 b)  TX bytes:480 (480.0 b)

... so the wireless interface is not being recognized / reported. As to the card, I think this is the relevant line from output of lspci:

03:00.0 Ethernet controller: Attansic Technology Corp. Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0)

... but maybe not? I do recall the make of the wireless card as Atheros.

Your showing that it is a atheros 1G Ethernet for eth0. If you do a 'lspic -vv' then a wireless chipset should show. Post that information. Then we can proceed from there.

Hi Gary -

When I issue 'lspci -w' I get


root@darkstar:~# lspci -w
lspci: invalid option -- 'w'
Usage: lspci [<switches>]

Hi, chexmix, onebuck means double 'v' but not a 'w' :P

chexmix 02-28-2011 06:10 AM

D'oh! My old eyes.

Okay. Issued the 'lspci -vv' command & got a load of output. Didn't see anything obvious when I scrolled through it, so grepped for 'Wireless' and 'Network' and found nothing (I checked another system to see what terms would be likely candidates for searching). Possible I am missing it.

Am going to try booting the Windows XP installation on the Netbook, bleah, to see if I have wireless there. If not, perhaps the hardware itself has gone south.

OK. Posting this from the Netbook w/ Win XP booted (wired network). It does appear there is a hardware problem: a) typically I am presented with a slew of annoying Windows messages about connecting wirelessly, and I don't do this at home, b) I cannot find the hardware via Control Panel.

Foo. Not what I had hoped for. Perhaps I am learning why Netbooks are as cheap as they are ...
