Trying to use email app with gmail wrong password when its correct

Question

this happened to me and it took me forever to figure out how to get my gmail to sync into my email app
on your phone all you do is goto your app and enter in your email and password for gmail or whatever.
then when it tries to save and all of that and the picture comes up saying incorrect then you click settings.
CLICK HOME BUTTON. GOTO SAFARI
type
http://www.google.com/accounts/DisplayUnlockCaptcha
click continue
account access enabled:
click create and application-specific password in blue
click visit your GOOGLE ACCOUNT SETTINGS PAGE
then password and security......type your password
click manage application-specific passwords
type in the box like gmail iphone
LETTERS POPP UP IN YELLOW copy and paste the four set of four
go back to your email where we clicked settings before now change your original REAL password and past that four set of four into it. that was the only way i could get my email to sync

Answer 1

Your AirPort Extreme supports WPA.
WEP is outdated and considered fairly useless, so use WPA.
Be sure you are using AirPort Utility  5.6. If you are not running Lion then use AirPort Utility 5.5.3.
AirPort Utility 6.0 cannot administer 802.11b/g base stations.
