I am working on a home gate product which uses Atheros mini-pci to support AP mode. The madwifi driver I am using is 0.9.2 and the Linux kernel is 2.4.20. When I built the madwifi as a part of Linux kernel, everything is working perfect. However, when I config  the madwifi as a loadable module, I have problem to bring up the wireless network interface. The commands I am using to check is as follows:


sh-2.05a# ifconfig ath0 up

sh-2.05a# iwconfig ath0

ath0      IEEE 802.11b  ESSID:""

          Mode:Master  Frequency:2.412 GHz  Access Point: Not-Associated

          Bit Rate:0 kb/s   Tx-Power:16 dBm   Sensitivity=0/3

          Retry:off   RTS thr:off   Fragment thr:off

          Encryption key:off

          Power Management:off

          Link Quality=0/94  Signal level=-95 dBm  Noise level=-95 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


Do anyone have similar issue and provide me a solution or any clue?
