my apple tv cannot connect after apple's update via wifi.
before I had no problem at all
Have you unplugged it form the mains and restarted it? Occasionally helps odd behaviour.
Restart iTunes and your router too.
Okey,by THE time I wrote my problem my appletv was unplugged.When I plugged it in on the main the problem was gone.
I could login again.
Thanks for your tip.
