Authenticating wifi users via mysqldb

I tried setting up freeradius with mysql based on the information from the wiki site. I can run radtest from the command line and authenticate a user in the database. Every attempt via wifi generates the error "Ignoring requests to authentication address * port 1812 from unknown client 192.168.226.248 port 58245" I have the following tables in mysql : nas, radacct, radcheck, radgroupcheck, radgroupreply, radposauth,radreply, radusergroup. I only have 2 test users in table radcheck, if that is the issue, what table fields should I populate to get one of my test users to authenticate via wifi? My objective is to only authenticate my wifi users via a central db, any recommendations for the basic way to achieve that is appreciated.
