WiFiXpert Compatibility Score — Amazon Fire TV Stick

Name: Amazon Fire TV Stick
Brand: Amazon

Tucked behind the TV in the worst possible spot for a signal, which is why it buffers when phones in the room don't.

What usually goes wrong

Constant buffering or "home is currently unavailable" in the evening.

Free things to try, in this order

1
Use the HDMI extension cable in the box so the stick isn't buried behind the screen.
2
Check the signal strength in the stick's own network settings.
3
Move the router higher and away from the TV's metal back.

Before you buy anything

A mesh box in the living room only if the signal reading stays weak with the extension cable fitted.

Answers about this gadget

Amazon Fire TV Stick — wi-fi keeps dropping

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.
