Modern Wi-Fi security Fully up to date with modern router security. | Excellent | 12/12 |
Happy on mesh Wi-Fi Handles mesh networks cleanly. | Excellent | 15/16 |
Works on a guest network AirPlay from your phone fails across a guest network. | Poor | 3/8 |
Survives a plug-in extender Copes, although 4K streams need real speed. | Fine | 6/8 |
Doesn't depend on chatty discovery AirPlay and HomeKit rely on background discovery messages that some routers filter. | Significant dependency | 15/16 |
Easy to fix when it goes wrong Clear settings and an Ethernet port that removes Wi-Fi from the equation. | Easy | 11/12 |
| WiFiXpert Compatibility Score | 88/100 | |
What usually goes wrong
AirPlay doesn't appear on the iPhone, or drops out halfway through.
Free things to try, in this order
- 1
Put the phone and the Apple TV on the same Wi-Fi name.
- 2
Turn off any isolation setting on the router so the two can see each other.
- 3
Plug the Apple TV into the router with a cable if one is within reach.
Before you buy anything
Only if 4K streams buffer with a strong signal — then it's your broadband speed, not the box.
Using it with your router or mesh
Answers about this gadget
What it needs from your network
Small Wi-Fi client, often tucked behind the TV inside a metal shadow.
- Bands it uses
- Both bands on current models; older sticks are 2.4 GHz only.
- How it's found
- Needs local discovery for casting and remote apps.
- Background discovery traffic
- Significant for casting.
- On a guest network
- Casting breaks.
- On a separate gadget network
- Keep with the household phones.
Getting it set up
- • Use the HDMI extension cable in the box — it moves the stick out from behind the screen and fixes a surprising number of complaints.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
With mesh Wi-Fi
- • Fine on mesh. Keep the phone that casts on the same network name.
