,

but then you've got almost immediately
[   18.926444] wlan0: Connection to AP c0:3f:0e:87:f3:0e lost.
It looks like mac80211 tries to monitor beacons and they are filtered by 
cw1200 device.

IEEE80211_HW_CONNECTION_MONITOR and / or IEEE80211_HW_BEACON_FILTER flags
(I don't remember, but both of them should be set) should prevent 
mac80211 from
monitoring. Please check if they are set in 
drivers/net/wireless/cw1200/main.c

Are you running with SDIO or GPIO IRQ?
