[Madwifi-users] AR242x: no scan results, can't connect

[Colin B. <cb...@li...>]

Hi all,

I am trying to get a AR242x-based adapter working on an Acer Aspire 4520
running Ubuntu 8.04. lspci output:

07:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg
Wireless PCI Express Adapter (rev 01)

Google brought me to this thread: http://madwifi.org/ticket/1192

Reading this and the first-time user how-to, I did the following:

* I removed the ath driver files included in Ubuntu;

* I downloaded a SVN snapshot yesterday, compiled and installed it;

* I also downloaded, compiled, and installed
madwifi-hal-0.10.5.6-r3698-20080604.

* I then rebooted.

wfconfig now indicates the following:

$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wifi0     no wireless extensions.

ath0      IEEE 802.11g  ESSID:""  Nickname:""
         Mode:Managed  Frequency:2.437 GHz  Access Point: Not-Associated          
Bit Rate:0 kb/s   Tx-Power:16 dBm   Sensitivity=1/1          Retry:off   RTS
thr:off   Fragment thr:off
         Power Management:off
         Link Quality=0/70  Signal level=-96 dBm  Noise level=-96 dBm
         Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
         Tx excessive retries:0  Invalid misc:0   Missed beacon:0

However, it can't see any access points:

$ iwlist ath0 scan
ath0      No scan results

I try connecting to a unencrypted WAP manually like this:

$ sudo iwconfig ath0 essid "myLinksys" key off

but no go:

$ iwconfig ath0
ath0      IEEE 802.11g  ESSID:"WestWind"  Nickname:""
         Mode:Managed  Frequency:2.437 GHz  Access Point: Not-Associated          
Bit Rate:0 kb/s   Tx-Power:16 dBm   Sensitivity=1/1          Retry:off   RTS
thr:off   Fragment thr:off
         Power Management:off
         Link Quality=0/70  Signal level=-96 dBm  Noise level=-96 dBm
         Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
         Tx excessive retries:0  Invalid misc:0   Missed beacon:0


Any ideas on what might be going on here?

Thanks.
