MacBook/iPad sees ATV's on neighbor's wifi.

[bulbed]

When I list the devices for AirPlay monitor or AirPlay audio on my Macbook (and iPad, and iPhone), I keep picking up what I believe is my neighbor's AppleTV device(s). See picture below (OS in Norwegian): Apple TV (2) and Lill_daatt are not mine.

How is this even possible, given that I'm the only one connected to my WPA2 Personal protected Wifi? (Airport Expresss 802.11n 2nd gen.)

More importantly, how can I remove them?

Or is it seeing your neighbours ATV on your wifi?

Time for a new password for your wifi...

and a stern talking to your neigbor

maybe you should call this guy to go sort him out

The only way they show up is if you are on the same network so your neighbor somehow found out your password.

I have this happen when I'm in a hotel on a shared network. Do you live in a building where a single Internet connection is shared?

I live in an apartment building with cable internet, so everyone is connected to the same node somewhere, but every apartment has its own modem and wifi router. However, if this were the problem, I would expect to pick up every ATV among the hundreds of apartments (and I don't understand how this would be possible anyway).

I'm pretty sure my neighbors are not connected to my network. The last time this happened I checked the Wifi client list, and it only found my own clients.

I know you probably don't believe me, so I'll make sure to get the client list and multiple ATVs in one screenshot.

Do you have powerline adapters? This member found out if not secured properly, it connects to his neighbor's network.

I've seen people post here over the years where they live in buildings where the Internet is shared, but each apartment doesn't get its own modem. So basically, the entire building is sharing one big local area network. But to your point, then you should be seeing every Apple TV.

Since you have a cable modem, none of your neighbors traffic should be coming across ethernet. And you're not seeing them as Wi-Fi clients on your router.

Wonder if it's this?

Use peer-to-peer AirPlay

With peer-to-peer AirPlay, your iOS device and Apple TV don't have to be on the same Wi-Fi network.

To use peer-to-peer AirPlay, you need one of these devices with iOS 8 or later:

• iPhone 5 or later
• iPad mini or iPad (4th generation or later)
• iPod touch (5th generation or later)

You can stream content to your Apple TV (3rd generation rev A, model A1469 or later) with software version 7.0 or later. Find out which Apple TV model you have.

Make sure that both devices have Wi-Fi and Bluetooth turned on.

If you want to stream iTunes Store content, you also need an Internet connection.

I suspect they are using a 2013 Apple TV with peer-to-peer airplay enabled. This allows Apple devices to connect to them directly via bluetooth and wifi, without having to be on a network.

I don't think you can remove it. You could, however, ask them to password protect their Apple TV so you can't accidentally mirror your devices to their screen. You may also want to rename your Apple TV connection for less confusion.

Sounds like a likely culprit, thank you. Now I just have to find out which one (or two) of my neighbors it is. And renaming my Apple TV would help, yes.
