I recently updated my Apple TV (3rd gen) to firmware 5.3.
After this update the wifi network reception on the ATV became unstable.
The ATV firmware update was the only action which I performed.
My network consists an airport extreme with the latest firmware (6.3)
I don't encounter issues on all other devices connected to my router.
Are there more people who are experiencing similar symptoms?
Can somebody suggest a solution?
One further addition: when the instability happens, the ATV doesn't detect any wifi netowrk anymore, while there are several in my environment.
One last addition, I already tried all steps as indicated on Apple's relevant support pages.
