I would troubleshoot by trying to connect it wired both computer and atv
if all is well there then I would know that the router was the issue
I would then test with another router periodic defects in routers making them behave erratic is not uncommon

This definitely helped. Trying this pointed to my PC. Turned out airplay was not loading when iTunes was started up. Had to restart my PC and then airplay loaded when I started up itunes. Once airplay was active home sharing worked on all my ATV's. I'll have to monitor and see how long this lasts.
