WiFiXpert Compatibility Score — Samsung smart TV

Usually fine, but the Wi-Fi aerial sits behind a large metal panel, which weakens the signal.

What we checkRatingPoints

Works on 2.4 GHz

Reliable, if slow, in far-off rooms.

Excellent13/14

Works on 5 GHz

Supported on most recent sets; 6 GHz only on the newest.

Supported12/14

Modern Wi-Fi security

Older TVs can force the router into an older security mode.

Good on recent sets8/12

Happy on mesh Wi-Fi

Fixed in one place, so roaming isn't usually the issue.

Good12/16

Works on a guest network

Casting from your phone fails across a guest network.

Limited4/8

Survives a plug-in extender

Fine for catch-up TV; 4K streams may still stutter.

Works6/8

Doesn't depend on chatty discovery

Screen mirroring and casting need local discovery messages.

Moderate dependency8/16

Easy to fix when it goes wrong

TV network menus are buried and awkward with a remote control.

Medium5/12
WiFiXpert Compatibility Score68/100

What usually goes wrong

Apps buffer in the evening, or the TV can't be found for casting from a phone.

Free things to try, in this order

  1. 1

    Try the TV on 5 GHz first; if it won't hold the connection, use 2.4 GHz.

  2. 2

    Move a mesh box into the same room rather than behind the TV.

  3. 3

    Use the TV's Ethernet port if the router is anywhere near.

Before you buy anything

If evening buffering happens on every device, it's the broadband. If it's only the TV, it's coverage.

Answers about this gadget

What it needs from your network

Wi-Fi 5 client in most sets, Wi-Fi 6 in premium models, with an aerial buried behind a large metal screen.

Bands it uses
Both bands, but the aerial is often poor because of the panel behind it.
How it's found
Needs local discovery for casting and for phone remote apps.
Background discovery traffic
Significant if you cast or use a phone as a remote.
On a guest network
Casting and phone remotes stop working.
On a separate gadget network
Keep TVs with the phones that cast to them.

Getting it set 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.

With mesh Wi-Fi

  • A mesh box with a spare Ethernet port near the TV lets you cable it — better than any Wi-Fi tweak.
