Airplay trouble

[rsantisteve]

Sometimes, exactly very often, I lose airpaly signal in my ipad, iphone..imac...to send the music to apple tv 2. It does not appear the icon. And later maybe appears.

I can not understant what's going on. I don't think is a problem with the wifi, because I can get music from my HD connected to the router.

Has anybody else the same problem? Any help?

My apple tv is jailbroken with black atv2.

And I try it with itunes, spotify, another players....

Thank you.
