My AppleTV says my iTunes password is incorrect, but it works on all other Apple devices. Help?

My AppleTV says my iTunes password is incorrect, but it is correct when logging in via my Macbook, iPad and iPhone.  Do I need to reset it entirely in order for it to work on all 3 devices?  This happened randomly without me logging out and back in, and I've already tried restarting the AppleTV.  I really dont want to have to create another new password.

Change your router channel number.  Most times this works & is all you have to do.
