airport connection problem

hi. i'm a newbie at this so please be patient w/ me. just bought a new ibook g4
1.2 ghz, 512 mb, os x 10.3.5 w/aairport card and a airport base station, went throgh the step by step install w/ the cd and it gets to the point where i can
get connected through the base station and the airport window saws im connnected but aol doesn't recognize the conneection. i double checked the access #'s ....the're ok. any help?
thanks in advance.......fletch

 

thank you for your reply, yes i'm on dial up. under aol preferences i don't see that option but i did disconnect the internal modem through internet connect. there is also a list of optional modems instead of the internal one but airport is not listed and i dont see the option of entering it to the list. i read the manual and i don't see this issue addressed.
