To piggyback on your questions: do any other WiFi networks in your vicinity use the same channel(s) as yours? Choosing a free channel should reduce the issue.
Also, reducing the amount of WiFi devices should also help.
Last thing, try the Wireless Audio Sync feature on your Apple TV: Settings, Audio and Video, Wireless Audio Sync.
Note on channels (simplified): Channels 1, 6 and 11 are the only non-overlapping below 36. Channels 2, 3, 4 and 5 overlap to some extent with 1 and 6. And channels 7, 8, 9, 10 overlap with 11, causing interference. These must not be confused with TV channels, which use a completely different frequency range for their channels.
