Count the worst evening, not the average one. A two-adult home with a teenager typically peaks at two live streams plus one on-demand title. Add a second TV in a bedroom and you are at three. Plans here run from 1 to 5 simultaneous connections, and picking that number correctly matters more than any hardware decision, because a stream refused for hitting the cap looks identical to a stream that failed. Installs are unlimited, so the app can live on every screen you own while only a few play together. Write down the peak count before you shop; it sets both the plan and the bandwidth arithmetic that follows.

Multiply, then add headroom. One 4K feed is 15-25 Mbps and about 7 GB an hour. One 1080p feed is 5-8 Mbps and about 3 GB. Three 4K streams together want 60-75 Mbps before phones, laptops, cameras and cloud backups are counted, which is why a household running several 4K feeds is usually comfortable on a 200 Mbps plan rather than a 100. HEVC helps here, carrying the same picture at roughly half the bitrate of H.264, so a device with hardware HEVC decode reduces what your line has to carry. Note the direction of that saving: it is a network saving, not a processor one.

Match hardware to the job the screen does. The main TV, where live sport gets watched, is the one that deserves an ethernet port; wire it and you remove distance, walls and interference in one step. Secondary TVs can run the cheapest current stick with hardware HEVC decode, because the server does the heavy work and the device only decodes and draws a list. Avoid very old hardware and abandoned Android boxes: no security updates, and a post-update playback regression on them stays broken. Devices with aggressive sleep timers also cut off paused streams, which reads as a service fault and is not one. One good device per active screen beats one premium device and three tired ones.

Live sport is the moment people judge a service, and the box is rarely the culprit. Diagnose by scope before blaming anything. If one channel stutters and the rest are clean, that is a single source. If a whole category fails, that is server-side and no household change touches it. If everything fails at once, look at the line, the player or the session. Then switch away and back: instant recovery means the session stalled and bandwidth was never the constraint. Streams arrive as roughly six-second segments, so a stall longer than the buffer becomes a visible freeze. Some of it is capacity on the service side, which is why a published uptime figure matters. Ours is 99.99%, about 53 minutes a year.

Three, and they are free. Hide unused channel groups: players hold the visible list in memory and destabilize above roughly 18,000 channels, and a 54,000+ channel catalog crosses that line easily if you leave every country switched on. Set the buffer to none or its lowest setting, because a long buffer delays recovery rather than preventing stalls. Point the device at a public DNS resolver, which resolves a fair share of channels that load slowly or refuse to start. Do all three before spending on RAM. The buying guides we compared discuss processors and voice control at length and never mention any of these, which is why readers upgrade hardware and see no change.
