Linksy router password problem with Wi-Fi/wpa setting?

I was able to setup my linksy web password and now my wireless has a code which worked fine when I tried to log in with my iphone. Problem is that my pw won't work when I try to log in with my iphone. I went to the 192.168.1.1 site and double check and my pw was the one I was typing but the password on the site's tab has longer digits even though I kept retyping and saving the password. I did some research online and I tried to go to wireless and change it to a Wpa instead of web but my linksy homepage isn't the same as the one I seen online, my wirless tab doesn't have the options to change it to a wpa. Any ideas how I can log in with the pw i created? And why my linksy page don't include the options as others do?

Just start all over. Push and hold the resset button on the back of the router.
go to the address bar and type routerlogin.net
loginwith username admin password: password
Wireless setup.

and so on.
