I need to use CHAP or PAP

Hello, I am using ANTCOR OS, intel IXP 533mhz chipset routerboard. I want to set Hotspot. I followed these steps to set up radius. http://ubuntuforums.org/showthread.php?t=478804&highlight=radius And here is my OS configure Wiki: http://wiki.antcor.com/wiki/index.php/Simple_HotSpot_Setup Now, I set up like those links but my Router cannot use FreeRadius. I think CHAP or PAP is not enabled. How can I enable it.
