Ethernet or WiFi connection to AppleTV?

I'm about to buy an AppleTV and want to know if there are any advantages to hooking it up to our Airport Extreme via an Ethernet cable as compared to using WiFi?


I can run a CAT6 cable to the Airport Extreme, but it will require considerable work. The Airport Extreme handles two laptops and two iPhones (not much use in the house). Two iMacs are hardwired to the Airport Extreme.


We mainly plan to use the AppleTV for Netflix and showing Aperture and iPhoto slide shows (photo albums) that would be on the iMacs.

iMac, Mac OS X (10.7.3)

How will we see a difference? How will higher network speeds help the AppleTV performance? AppleTV uses UDP data streams which are fixed and slow, relative to Ethernet and 802.11ac wi-fi.


Not according to this article: Apple TV: TCP and UDP ports and protocols used - Apple Support

....and good thing too; UDP is best confined to live audio/video streaming and VoIP.

Also the relative performance of TCP and UDP depends entirely on the kind of traffic you're sending, e.g. lots of small files, or fewer big files. For tiny files, UDP has the edge, but for larger files TCP wins out (that's a gross generalisation though).

So... like many others, I assumed "Ethernet every time", until I upgraded to the latest Airport Extreme Base Station (which supports up to 802.11ac).


Over Wifi (802.11n at 5GHz from the AppleTV)...

  • the AppleTV in my living room (1st floor, 6 inches from the AEBS) gets 279Mb/s.
  • the AppleTV in my kitchen (ground floor) gets 205Mb/s


Both of these easily trump the 100Mb/s Ethernet port on the AppleTV (which in practice only manages around 93Mb/s).


Moral: don't assume - test the speeds you're getting from your WiFi, and check which of your ethernet-enabled devices actually have Gigabit Ethernet because even in 2015, many do not.

While I agree that ethernet is better than wi-fi for dependability, my AppleTv is on wi-fi and is working great.


I have an Airport Extreme and two Airport Expresses that are used to extend the wi-fi and airplay music on speakers. On ethernet I have iMac, Windows Laptop and PS3. On wif-fi I have Linux laptop, Macbook, iPhone, Blackberry, iPod Touch, Wii, and AppleTV. The AppleTV connects to the Airport Extreme wi-fi and works great. The Airport Extreme is in the basment in the middle of the house and the AppleTv is on the main floor at an outside wall about 20 feet from the Airport Extreme. The Airports, Macs, iPhone, iPod Touch and AppleTV are all at the latest software version. The house is has only one close neighbour so the interference from other wi-fi is minimal and weak.

If Apple ever release an 802.11ac version of the AppleTV (and let's hope so) then you'll really see a difference. I have the new iMac Retina with 802.11ac and get around 500-600Mbps over TCP to my AEBS.


EDIT: ran iPerf301 -s on a Macbook Pro Retina connected via Gigabit Ethernet to the AEBS


then ran iPerf301 -c <Macbook IP Address> -P 20 over 5GHz WiFi channel

Thanks for the info, I didn't know about all the ports used.


I still don't see how increasing the AppleTV connectivity bandwidth would be of any value. The video and audio streams are still a fixed size and much smaller than the current AppleTV bandwidth on ethernet or a good wif-fi connection.


All of my AppleTV activity is video, audio, and pictures. My AppleTV current connects to a Airport Express at 65Mbps. The Airport Express is extending the wi-fi connected to an Airport Extreme via ethernet. The HD video, netflix, audio all stream to the AppleTV at far less than 65Mbps, so I see no need for the AppleTV to have 802.11ac speeds.
