Televisions and your Wi-Fi
Big screens with surprisingly ordinary Wi-Fi.
What this kit needs from a network
Wi-Fi 5 client in most sets, Wi-Fi 6 in premium models, with an aerial buried behind a large metal screen.
- Bands
- Both bands, but the aerial is often poor because of the panel behind it.
- How it's found on the network
- Needs local discovery for casting and for phone remote apps.
- Background discovery traffic
- Significant if you cast or use a phone as a remote.
- Guest networks
- Casting and phone remotes stop working.
- Separate IoT network (VLAN)
- Keep TVs with the phones that cast to them.
Setting it up
- • Use the 5 GHz name if the router is in the same or next room.
- • A cable to the TV is the single best upgrade if the router is close.
- • 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.
Mesh considerations
- • A mesh box with a spare Ethernet port near the TV lets you cable it — better than any Wi-Fi tweak.
Router requirements
- • 5 GHz within range for 4K streaming
- • Casting traffic allowed on the network
The kit we've checked
- Samsung smart TV 68/100
Usually fine, but the Wi-Fi aerial sits behind a large metal panel, which weakens the signal.
Most common complaint: Apps buffer in the evening, or the TV can't be found for casting from a phone.
- LG smart TV 68/100
Wi-Fi aerials point backwards into the wall, so a TV on a bracket often gets a worse signal than your phone in the same room.
Most common complaint: Buffering on 4K, or the TV drops off Wi-Fi every night.
