I have a mid 2011 macbook pro running mavericks (upgraded last night) I seem to notice that the apple tv's airplay icon is not showing up even after a long wait upon power up. This used to happen all the time, ever since I bought the apple tv a few months ago. The problem used to go away on it's own sometimes and once in a while I had to switch the ATV ON and OFF and wait for a couple of minutes and the airplay icon used to show up. I have the ATV and MBP updated with latest software.Why does this happen ? How do I get this sorted ? Additional Info: Broadband has no problem. Very fast N router.Checked and ruled out interference with other channels on 2.4GHz.
