Apple TV will not connect to the internet or iTunes store or other programs such as netflix. All my other devices can connect to internet.

My Apple TV will not connect to the iTunes store or the internet, although it shows as having strong signal through wifi. I run troubleshooting and network test for download speeds, and all it says is "Accessing iTunes" then "Cannot not connect to iTunes". This doesn't happen all the time only intermittent, and has only started happening the past two weeks.

All my other devices can connect to the internet through my WiFi, like my iPhones, iPad, laptops and xbox.

My Apple TV has software version 6.2.
