Do you need a better router for IPTV? Usually not
This is the upgrade people reach for first and the one that helps least often. A new router is a genuine fix for a specific set of problems, and does nothing at all for the ones most households actually have. Here is what replacing it genuinely improves, what it cannot touch, and — the useful part — the order to spend money in, which starts at nothing and only reaches a router near the end.
The order to spend money in
Start here, because most people never get past step two.
| Step | Cost | Fixes |
|---|---|---|
| Move the router | £0 | Poor coverage from a bad position |
| Choose the band manually | £0 | A device stuck on a weak 5 GHz signal |
| Turn off unused devices | £0 | Airtime taken by things doing nothing |
| Ethernet cable | £8–£15 | Everything, for one fixed device |
| Powerline adapters | £40–£80 | A room where a cable is impossible |
| Mesh system | £120+ | Genuine coverage gaps across a large house |
| New single router | £80+ | Only the specific cases below |
The fourth row is the one to notice. For a television that never moves, an Ethernet cable is not a lesser option than a better router — it is a categorically better one, at a tenth of the price. It removes distance, walls, neighbours and competing devices in a single step, none of which a new router eliminates.
What a new router genuinely improves
Three things, and they are real.
Handling many devices at once. Newer Wi-Fi generations are better at serving a crowded household — they schedule several devices more efficiently rather than dealing with them strictly one after another. In a house with twenty-odd connected things, that is a meaningful difference.
Access to a 5 GHz band. If your router is old enough to be 2.4 GHz only, it is working on the most congested part of the spectrum with no alternative. That is worth fixing, and it is the clearest single reason to replace.
Raw capability. An old router's processor can become the bottleneck when several devices stream at once, regardless of the line behind it.
What it does not improve
Four things people expect and do not get.
Your line speed. A router distributes what arrives; it does not create more. If your package delivers 40 Mbps, a £200 router delivers 40 Mbps.
Physics. A solid brick wall attenuates a 5 GHz signal by roughly the same amount whichever router is transmitting. Better hardware helps at the margins; it does not see through walls, and British housing has a lot of them.
Provider-side problems. If a stream breaks up because a server is busy at nine on a Saturday, nothing in your house changes that — which is why the mobile data test in our guide to finding the real cause of buffering should come before any purchase.
Coverage, if you buy a single router. This is the most expensive misunderstanding. One better router in the same bad position produces almost the same coverage as the old one. Coverage problems need more transmitters, not a better one — which means mesh, or a cable.
Is the router your provider gave you actually bad?
Less than the internet suggests. Routers supplied by the major British broadband providers have improved considerably, and for a typical household they are adequate. The reflex to replace one on principle usually costs money without changing anything measurable.
Three situations where the supplied unit genuinely holds you back:
- It is several years old and predates 5 GHz, or supports it poorly.
- It gives you no control — no way to separate the bands, choose a channel, or see which devices are connected.
- It has too few Ethernet ports for what you want to wire up, though a £10 switch solves that far more cheaply than a new router.
Otherwise, the position it sits in matters far more than the badge on it.
When an upgrade is the right answer
Four situations where buying something genuinely makes sense.
A large or multi-storey house. Buy a mesh system, not a single router. Two or three units placed sensibly beat one powerful one every time, because the problem is distance rather than power.
A very old router. If it is 2.4 GHz only, replacing it is worthwhile on its own.
A crowded household. Twenty or more connected devices, several streaming at once — this is where newer Wi-Fi generations earn their money.
A flat in a dense building. Where dozens of neighbouring networks compete, a router with better band steering and channel selection helps. Though even here, a cable to the main television helps more.
Note what is not on that list: a single television that stalls in one room. That is a cable, or at most powerline.
If you are buying, what to look for
- Mesh, if coverage is the problem. Look for a system with a dedicated link between units rather than one that relays over the same band it serves — the latter roughly halves throughput at each hop.
- Dual band at minimum, with the ability to separate the two networks if you want to pin a device to one.
- Enough Ethernet ports. Wiring the main television is the highest-value thing the router will do for you.
- A WAN port that matches your line. On a fast full-fibre package, a router limited to a slower WAN port becomes the bottleneck.
- Ongoing firmware updates. Less exciting than the specification, more important over three years.
What you can safely ignore is the headline speed number on the box. Those figures combine every band at once under laboratory conditions and bear no relationship to what one television receives in a back bedroom.
Router settings that matter — and one that usually doesn't
Separate the bands. If your router publishes one network name for both, consider splitting them so you can attach the television deliberately rather than letting it drift onto a weak 5 GHz signal mid-programme.
Let channel selection be automatic, unless you have looked at what your neighbours are using. Automatic is usually right; a manually fixed channel chosen years ago often is not.
Keep the firmware current. Most modern routers do this themselves. Worth confirming once.
Quality of Service is usually not the answer. The traffic prioritisation feature sounds tailor-made for streaming and rarely helps in practice. On a fast line there is enough capacity that prioritisation is irrelevant, and on some routers enabling it actively reduces total throughput because the processor has to inspect every packet. Try it if you like, and measure before and after rather than assuming.
The cheapest upgrade nobody makes
Worth repeating because it is so easily skipped: move the router before you buy anything.
High, clear of obstructions, away from the consumer unit, out of a closed cupboard, and as central as the master socket allows. In British homes that socket is often in a hallway or under the stairs, so the router ends up wherever the line arrived rather than where the signal is needed. A longer lead from the socket is a few pounds and moves the whole thing.
One more free change: if your streaming device is a stick tucked behind a wall-mounted television, a short HDMI extension that brings it out from behind the screen improves reception and reduces heat. Sticks rarely have an Ethernet port, which is one reason a set-top box can be the steadier choice — see our guide to MAG and Formuler boxes.
In short
A new router fixes a crowded household, a router too old for 5 GHz, and genuine coverage gaps — the last of which needs mesh rather than one better unit. It does not create line speed, see through walls, or repair anything at the provider's end.
For the commonest problem of all, a single television that stalls in one room, an Ethernet cable at around £12 is a better fix than any router at any price. Spend in order: move it, choose the band, thin out the devices, then run a cable. Most people stop there.
And diagnose before you spend. Our guides to why faster broadband won't fix it and working out which problem you actually have will usually tell you whether hardware is the answer at all.
Frequently asked questions
Sometimes, but it is rarely the best first purchase. If one fixed television stalls, an Ethernet cable at around £12 fixes it more completely than a router at ten times the price, because it removes distance, walls and competing devices altogether. Diagnose the cause before buying anything.
Usually yes. Routers supplied by the major UK providers have improved a great deal and are adequate for a typical household. Replace it if it is several years old and 2.4 GHz only, or if it gives you no control over bands and channels. Otherwise its position in the house matters far more than the badge on it.
Mesh, if coverage is the issue. One better router in the same position produces almost the same coverage as the old one, because the problem is distance rather than power. Look for a system with a dedicated link between units — one that relays over the same band it serves roughly halves throughput at each hop.
Usually not. On a reasonably fast line there is enough capacity that prioritisation makes no difference, and on some routers enabling it reduces total throughput because the processor has to inspect every packet. If you try it, measure your speed before and after rather than assuming it helped.
Ignore the headline number on the box — it combines every band under laboratory conditions and bears no relationship to what one television receives in a back bedroom. Look instead for dual band, enough Ethernet ports, a WAN port that matches your line, and a manufacturer that still issues firmware updates.
