How mesh works
A mesh system has a main unit connected to your broadband router (or acting as the router) and one or more satellite units around the home. They broadcast one network name, and your devices connect to whichever unit gives the best signal. The satellite near the TV passes your stream back to the main unit, and that link between units, the backhaul, decides how good the result is.
Wireless or wired backhaul
| Backhaul | How it works | For IPTV |
|---|---|---|
| Wireless | Units talk to each other over Wi-Fi | Fine if units are close enough for a strong link; each hop shares wireless capacity |
| Wired (Ethernet backhaul) | Units connect with network cables | Best: the full speed reaches the satellite |
TP-Link’s documentation for its Deco systems says Ethernet backhaul lets units talk over a cable instead of Wi-Fi, with lower latency and no bandwidth lost to a wireless hop. You don’t have to wire every unit; it applies between the units you cable together, and switches on automatically.
If you can’t run cables, powerline adapters can carry the backhaul instead, with mixed results depending on your wiring. See powerline adapters for IPTV.
Placing the units
- Main unit: next to your broadband router, connected by cable.
- Satellites: about halfway between the main unit and the TV, not right next to the TV in a weak spot. A satellite needs a good signal itself to pass on a good one.
- Avoid cupboards, behind TVs, and next to large metal objects or fish tanks.
- Connect the TV or stick by cable to the satellite, if it has a network port. That avoids one wireless link entirely.
Mesh, extender or cable?
| Option | When it fits |
|---|---|
| A network cable to the TV | The most reliable; worth it for the main TV |
| Mesh with wired backhaul | Large homes or several weak rooms, with some cabling possible |
| Mesh with wireless backhaul | Medium homes without cabling; place units carefully |
| Powerline | Where Wi-Fi can’t reach and cables can’t go |
| Basic Wi-Fi extender | A cheap stop-gap; often slower than mesh |
Before buying anything, check that the TV is on the 5 GHz band and that the problem really is Wi-Fi: if the same channel buffers on a phone right next to the router, mesh won’t fix it. See Wi-Fi bands for IPTV and how to stop IPTV buffering.
