British households have more devices than ever. In fact, most people can’t quickly count the number of devices, forgetting things like the Ring doorbell that now relies on it.
The issue is that broadband fails quietly. You never get an alert or warning, you’re just gaslit into thinking the poor quality Whatsapp video call is because of their connection, or that you’re losing your reflexes when getting hit on Valorant. Perhaps it’s just a poor ping.
Why your home network is quietly struggling
The average UK household now has 10 to 15 connected devices. Some have way more, like 30. A family of four will average two or three devices each (e.g., phone and game console), and then there are some household devices, like the TV, smart speakers and doorbell. More and more people are ditching cable television too, so we will only see this increase.
FTTC connections, where the fibre only reaches the street cabinet, compounds the issue. The copper wires slow down bandwidth and reliability, making it less capable of facilitating this many devices. If you’re comparing broadband deals, the infrastructure (having full fibre to your premises) is a huge factor.
What streaming actually demands from your connection
4K HDR streaming uses around 25 Mbps per stream, sometimes more. Three simultaneous streams, which lets face it, is very common in a household with teenagers, already demands 75+ Mbps alone. That’s tight for what many FTTC connections deliver, especially at peak hours.
Raw speed is really just half of the story. The real issue for streamers is bufferbloat. This is a condition where a large background download floods the connection’s queue and stalls everything else. Now, your downstairs stream has cut back to 480p resolution.
Speed tests don’t catch all this. A connection can pass a speed test and still buffer. Netflix, Disney+, etc. just silently drop to lower resolutions when the bandwidth becomes inconsistent. You may not be getting the 4K you’re paying for.
Gaming and video calls
For gaming, download speed can be a distraction. What matters is latency. Ideally you will have under 20ms before it becomes noticeable. A connection with high jitter (variance) at 50ms will feel worse in-game than a rock-solid 30ms connection. Most people never think to test the variance.
Video calls are a different problem altogether – an upload one. The average UK home broadband upload speed was just 18.4 Mbps compared to an average download of 69.4 Mbps. The difference can be fine, but once you try working from home, video calling, or uploading things to the cloud, you’ll know. Especially the ghosting. Full fibre will provide better upload speeds.
Future-proofing for real
Start with the connection itself. Full fibre (FTTP) means you skip the copper entirely. No more degradation or slow upload speeds.
Inside the home, you want to wire your most demanding devices where possible. Things like consoles and desktop PCs. Ethernet removes the RF interference and WiFi contention that a speed test misses. Fewer invisible problems.
Avoid range extenders where possible as they reduce bandwidth. Mesh systems use a dedicated backhaul channel instead, preserving throughput. It’s the future.
If you’re buying a new laptop or similar, look for Wi-Fi 6 (802.11ax). It supports more simultaneous device connections through OFDMA – reducing congestion is something we need to think more about going forward.
Buffering, lag, and ghosting are different symptoms of the same infrastructure problem. Full fibre with a modern router and wired/mesh connections, and you’re all set.
