 Posted: Sat Feb 17, 2007 4:29 am Post subject: wpa_supplicant and atheros: scans but will not associate |
 |
|
Problem: Using wpa_supplicant and an atheros card, APs can be scanned but no association made, even on an open AP
Symptom: When wpa_supplicant is run manually, it can be seen that it is able to see the available access points but it then is unable to associate with the configured AP.
Base hardware: IBM Thinkpad T60 with an IBM a/b/g (Atheros) wireless card

ifconfig ath0:[quote]
This repeats over and over; I have stopped it with a control-c.
This is a new laptop, so I also gave it a try with Knoppix 5.0.1. I could not get an ath0 at all using that.
I have tried dropping back one version of madwifi-ng, to no avail.
I have followed the think-wiki guide to configuring the kernel - I can post the .config file if necessary.[/code]

|
|
Update:
I poked around with manual iwconfig commands and was able to get it to associate once I did:
| Quote: |
iwpriv ath0 mode 2
|
I also discoverd that I did not, as I thought, have dhcpcd installed. But that probably wasn't keeping it from associating.
I went back and tried wpa_supplicant and was able to get it to work with open, WEP and WPA.
Now, I have a WAP54G, which is set up in mixed-mode. I can only get it ath0 to associate using 802.11b though.
I tried setting the AP to g-only, but it did not help.
So, I am not sure what the deal is, but mode 2 (802.11b) is fine for now. I am glad for not having to install windows to make sure this brand-new laptop is working.
The default is mode 0 (auto) (from http://madwifi.org/wiki/UserDocs/iwpriv). Not sure whay that would not work.
Interestingly, the wireless light does not come on once it associates.
Problem resolution:
'iwpriv ath0 mode 2'
Hope this helps someone else trying to get madwifi to work.

|
|
I know this post is a little old but I came across it today and if this is still a problem I may have the solution. The following line in your /etc/conf.d/net might be the problem:
| Quote: | | wpa_supplicant_ath0="-Dmadwifi -c/etc/wpa_supplicant/wpa_supplicant.conf" |
Madwifi-ng uses -Dwext now instead of -Dmadwifi. I use that setup with my madwifi card and it works well with wpa_supplicant. |
