You can start hostapd with more than one config:
hostapd config1.conf config2.conf ... configN.conf

Yes! You need wlan_tkip and/or wlan_ccmp loaded depending on your
hostapd config (wlan_crypt_tkip was the wrong name). Normaly these
modules should be loaded automaticaly if needed. But on some plattforms
it fails.

Everythink seems ok - what is the problem? What says hostapd log (start
with hostapd -ddd /your/path/to/config). One issue is that you have to
set essid with iwconfig. Set mode to master by iwconfig is a good idea

I think you doesn't need WE18. It works with 2.4.26 and WE16 for my
