Why does IBO Player buffer even when my phone shows strong Wi-Fi?

A phone and a Samsung smart TV use different Wi-Fi antennas, and the TV's is typically less sensitive. Strong signal on a phone in the same spot does not mean the TV is receiving enough bandwidth to hold a live stream without interruption.

Will clearing the cache on the Samsung log me out of IBO Player?

Clearing the cache removes temporary files but not the app's core login data. IBO Player ties your access to the TV's MAC address and device key rather than a typed password, so the link to your subscription stays in place.

Does switching DNS affect anything else on the TV?

Changing the DNS only affects how the TV resolves web addresses into server locations. It does not alter any other setting, and you can switch it back to Automatic at any time from the same IP Settings screen.

My stream is fine in the evening but drops in the afternoon — is that the router?

Afternoon drops usually point to network congestion rather than your hardware: more devices in the neighbourhood are sharing the same Wi-Fi channels. Switching to the 5 GHz band, or moving to a wired connection, will largely insulate you from that kind of interference.

A steadier Wi-Fi signal for IBO Player on your Samsung TV

Published 5 Nov 2026 · Reading time: 6 min read

IBO Player stops to buffer for a reason: somewhere between your router and the Samsung TV, the signal is too weak or too inconsistent to hold a live stream. The fixes below are ordered by how often they actually solve it, so start at the top and move down only if you need to. Most households find the problem earlier in the list than they expect.

Check the router before the app

The TV's Wi-Fi radio is not the strongest in the room. A router tucked behind a cabinet, or one floor away with a concrete ceiling between, will show full bars in the Samsung's network settings and still deliver an unstable connection — bars measure signal strength, not the quality of what gets through.

Start with the physical situation. Move the router closer to the TV if you can, or at least into the same room temporarily to confirm that distance is the cause. If the picture clears up immediately, you have your answer.

If moving the router is not practical, a powerline adapter or a Wi-Fi mesh node placed nearer the TV will give you a wired-quality path without running a cable across the room. This is the fix that holds longest, because it removes the air entirely from the equation.

Once the physical side is settled, restart both the router and the TV before testing again — a cold restart clears connection state that a simple refresh does not.

Switch the TV to the 5 GHz band

Most routers broadcast on two frequencies. The 2.4 GHz band travels further but shares space with neighbouring routers, microwave ovens and other household devices, making it noisy. The 5 GHz band is faster and far less congested, though it does not reach as far through walls.

On your Samsung, go to Settings > General > Network, then open your Wi-Fi list. If your router broadcasts separate names for each band (something like HomeNetwork and HomeNetwork_5G), connect to the 5 GHz network. If the router uses a single name for both, log into its admin page and split them — the router's manual or the label on its underside will tell you the address to type into a browser.

If you are sitting close to the router, 5 GHz will almost always give IBO Player a cleaner, more consistent feed. If the TV is two rooms away, 2.4 GHz may actually be the better choice for that distance — test both and watch for a few minutes before deciding.

Change the DNS on the Samsung

The TV's default DNS server is usually assigned automatically by the router, and it is often slower than it needs to be. Switching to a faster public DNS can reduce the small delays that cause a stream to stall at the start or drop mid-way through.

Go to Settings > General > Network > Network Status > IP Settings. Set DNS from Automatic to Enter manually, then type 8.8.8.8 as the primary address. Save, then run the connection test on the same screen — it should complete in a moment.

This is a small change, but on a congested home network it is often enough to stop the occasional freeze that interrupts a stream.

Clear the IBO Player cache and re-launch

If the signal itself is solid but the app still stutters, the problem may be inside the app rather than the network. The Samsung OS lets you clear an app's stored data without uninstalling it.

Go to Settings > Support > Device Care > Manage Storage, find IBO Player in the list, and clear its cache. Then press the Home button, close the app fully from the recent-apps tray, and reopen it.

IBO Player identifies your TV by its MAC address and device key, both of which the app displays on its main screen before you sign in. These do not change when you clear the cache, so your subscription stays linked to this TV and the login details sent to your email address still work without any re-entry.

Anyone setting up a new subscription can find the available plans on the UK IPTV home page. For a broader look at what is available, best-uk-iptv.xyz is an independent site worth a visit.

When nothing else works: consider a wired connection

A Samsung smart TV has an Ethernet port on the back. If you have tried every wireless fix and the stream still drops, a cable from the router to that port will settle the connection permanently. Wi-Fi is convenient, but a wired link removes every variable that makes wireless streaming unpredictable.

If the router is too far away to run a cable directly, a powerline Ethernet kit uses the existing wiring in your walls to carry the signal — the connection the TV sees is wired, with none of the interference that air introduces.

Once you are on a wired connection, IBO Player should behave as if the network issue never existed. Channels that required searching by category — the kind of workflow described in the guide to snooker channels: categories, favourites and search — will load without the pause that makes browsing frustrating on a weak signal.

For households that also stream on a phone or tablet, the article on AirPlay at home and what it actually does covers how to keep those devices on a stable path as well. And if rugby is part of the weekly schedule, the guide to finding Six Nations channels around a busy family routine shows how to track down the right channel quickly.
