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
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?
