Dear All, I installed a new wifi mini-pci card in my notebook. It has the Atheros AR9220/AR9223 chipset. When I boot into level 5 and su to root, I run modprobe ath9k and I get error messages from multiple components of ath9k Here is some info: # ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:814 (814.0 b) TX bytes:814 (814.0 b) # ifconfig ath0 ath0: error fetching interface information: Device not found # modprobe ath9k WARNING: Error inserting ath9k_hw (/lib/modules/2.6.37-1.fc13.i686/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko): Invalid argument WARNING: Error inserting ath9k_common (/lib/modules/2.6.37-1.fc13.i686/kernel/drivers/net/wireless/ath/ath9k/ath9k_common.ko): Invalid argument WARNING: Error inserting compat (/lib/modules/2.6.37-1.fc13.i686/updates/compat/compat.ko): Invalid argument WARNING: Error inserting mac80211 (/lib/modules/2.6.37-1.fc13.i686/updates/net/mac80211/mac80211.ko): Invalid argument FATAL: Error inserting ath9k (/lib/modules/2.6.37-1.fc13.i686/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko): Invalid argument
