wpa_supplicant with madwifi-ng Scan timeout (30 seconds to associate)

It takes 30 seconds to associate with the access point using
wpa_supplicant with madwifi-ng. Most of this time appears to be waiting
for the scan to timeout. Scanning seems to be fast using normal
utilities such as iwlist. (I have including timing from iwlist below.
The wireless connection does work after waiting the 30 seconds for the
association.
Summary of versions:
- Linux: 2.6.15.4
- wpa_supplicant: latest CVS
- madwifi-ng: svnversion 1452
Here is a snippet of the full wpa_supplicant output that shows the 30
second delay (I added the blank line to show where the delay is):
1140414357.823834: State: DISCONNECTED -> SCANNING
1140414357.823858: Starting AP scan (broadcast SSID)
1140414357.823908: Wireless event: cmd=0x8b1a len=8
1140414387.825829: Scan timeout - try to get results
1140414387.825963: Received 333 bytes of scan results (1 BSSes)
1140414387.825978: Scan results: 1
I have included in this e-mail the following information:
- wpa_supplicant version
- cat /etc/wpa_supplicant.conf
- Access Point Information
- madwifi-ng information from dmesg
- /sbin/iwconfig ath0
- time iwlist ath0 scan
- /usr/local/sbin/wpa_supplicant -d -K -t -i ath0 -D madwifi -c /etc/wpa_supplicant.conf
Does anyone have any suggestions for me as to how to speed up the association?
Thanks for your help,
