Which version of Linux kernel and Host AP driver are you using?

The most common reason for this type of error would have indeed been
ieee80211_crypt_tkip and _ccmp not being loaded..

Assuming you are using a recent Linux kernel, you could also use -Dwext
which is the standard interface for Linux drivers. I'm not sure whether
it could help in this particular case, but could be worth a quick test
anyway.

Do you see any error messages in 'dmesg' output from kernel after this?
