Need help changing my Linksys WRT54G Router Security Password

[TechCom0018]

I have a Linksys WRT54G Router and I was able to change my security password from WEP to WPA. But the problem is that Linksys default for a WPA Algorithm is TKIP and I want to change it to AES, and I'm having trouble changing those settings.

Here's a picture of what the Linksys' Manual saids to do:

and here's what my Linksys settings look like via Firefox browser access:

Also here's the link for the user manual for the Linksys Router:

So if anybody can help me out I would greatly appreciate it.
