..:::: Linux v2.6.18, Madwifi Driver, Atheros cards issue ::::..

maloomnahi · 08-27-2008, 09:32 PM

Dear All,

My current inventory in LAB is as follows:
1] One cisco 1242AG AP with following software running on it:
Product/Model Number: AIR-AP1242AG-K-K9
System Software Version: 12.4(10b)JA
Bootloader Version: 12.3(7)JA1

2] Atheros WLAN PCI card with Madwifi v0.9.3.1 in a Linux Machine v2.6.18

My Aim: Associate Cisco AP and Atheros card using WPA-PSK with AES-CCMP or TKIP using open authentication algorithm

My current setup of these devices:
1] Cisco 1242 AG : More details below
- WPA PSK with the PSK set to "12345678"
- CCMP as cipher, WPA version 2
- No VLAN settings
- Essid CISCO_AP

2] Atheros Card settings
- WPA 2, cipher as CCMP, key MGT algorithm set to 3
- WPA PSK with the PSK set to "12345678"
- Station managed mode with essid "CISCO_AP"

Problem Faced: Association never happens
Cisco probe response shows "Station does not support the concerned authentication algorithm error = 0x000d"

My Findings and Questions:
1] The same setting works out with WPA Supplicant very well.
2] Key generated by the Atheros Madwifi is of 64 bits and not 128 bits like WPA Supplicant or Cisco. Is there any way we can set the key length to 128 bits in Madwifi-Atheros?
3] What could be the reasons behind the non-association?
4] Any settings missing in Cisco or Atheros?
5] Similar settings between Atheros AP and Atheros STA works fine.
6] Have already tried various madwifi commands and settings same 128 bit key of WPA Supplicant, but no use.

Looking forward to your reply and support ASAP.

Thanks,
