What WiFi: is buying your own router worth it?

Buying your own router or mesh system is worth it if your Wi-Fi does not reach the rooms you use, or if you want controls your provider's hub does not offer. If the hub you were given already covers the house, it is not.

There is also a cheaper middle course: keep the provider's hub and add your own Wi-Fi units to it. You need not sack the whole orchestra because one bedroom cannot hear it.112

The timing matters this winter. The old copper phone network is being switched off, and most landlines will soon plug into the broadband router, which gives the supplied hub a new job that a shop-bought one may not be able to do.2

First, find out what is actually slow

Broadband is the connection coming into the house. Wi-Fi is the radio network inside it. A new mesh cannot turn a 70Mbps line into a 500Mbps one, however hard you stare at the Wi-Fi 7 sticker; it can only help you get more of what you already pay for in the rooms where you use it.1

So test before you shop. Plug a laptop into the hub with an Ethernet cable and run a speed test, then repeat over Wi-Fi next to the hub and in the problem room. A slow wired result points to the line or the package; a good wired result and a poor result upstairs points to coverage.

Then move the hub. The BBC's technology column reported in July that thick walls, mirrors, large TVs and even fish tanks can weaken or bounce the signal, and that a central, high spot is the best free fix. Getting the router out of the cupboard costs nothing and inconveniences no fish.3

What your own kit does better

Coverage. A mesh system spreads several units around the home under one network name, rather than asking a single box by the front door to reach the loft. Which? advises spacing a two-unit system about 10 to 15 metres apart, and suggests a £40 to £80 extender is enough when the problem is a single room.4

Mixing brands rarely produces one tidy mesh. Google's Nest Wifi Pro, for example, cannot join older Nest or Google Wifi points.5

Control. Which? found that third-party routers tend to adopt new Wi-Fi standards sooner than provider hubs, and give you more say over device priority, guest networks and parental controls. Its testers judged many provider routers "mediocre", although some did well.4

Shop-bought systems list features such as device prioritisation, guest networks, VPN tools and device isolation. Some of those vanish when the unit runs in access-point mode, so check the one feature you need rather than the word "pro" on the box.67

Portability. Your own Wi-Fi kit can stay when you switch provider, so the network name and every smart plug keep working. Provider kit often has to go back: BT expects its Complete Wi-Fi discs to be returned when you leave.10

Speed, within reason. Wi-Fi 7 adds features such as multi-link operation, but only devices that support it benefit. The cheaper Deco BE25 and eero 7 are dual-band and do not use the 6GHz band at all, whatever the number on the box suggests.68

For gigabit broadband, the wired ports matter too. Deco BE25, eero 7 and the ASUS BT8 all have 2.5Gbps ports. Headline speeds add up the theoretical capacity of every radio and are not a promise for any one phone.687

When the provider's hub should stay

The biggest reason is the phone. The industry aims to move every BT Openreach landline to a digital service by 31 January 2027, and the Independent reported on 2 November that customers will plug their handset into the broadband router rather than the wall socket.2

EE, for instance, says its Digital Home Phone needs an EE or BT hub as the main router. Some TV and backup features also depend on supplied equipment, and EE's helpdesk will not troubleshoot a third-party router.1

Power cuts are the other worry. The BBC reported on 27 October that MPs for rural seats warned digital landlines fail when the router loses power, unlike the old copper network; providers must offer vulnerable customers a free battery backup.2

The fair comparison is not always shop-bought mesh against a basic hub. BT Complete Wi-Fi adds discs to a Smart Hub, up to two more if needed, with a coverage guarantee for the main home rather than the shed. Sky WiFi Max is Sky's equivalent. Ask for the equipment, terms and total contract cost at your address.1011

Subscriptions can change the sums. Deco's advanced HomeShield features and eero Plus cost extra, while a provider add-on charged at £10 a month comes to £240 over two years before any price rises.68

Three ways to connect your own kit

1. Keep the hub, add access points. The hub still handles the internet connection and the phone; your units provide the Wi-Fi. This is usually the least fiddly option.
2. Put the hub in modem mode. The hub passes the connection to your router and stops routing itself. Virgin Media's hubs are the familiar example.
3. Replace the hub. On suitable full fibre, your router plugs into the fibre box on the wall, the optical network terminal, and signs in with the provider's settings.

Two things catch people out. Running two routers by accident creates "double NAT", which can upset gaming and video calls. And part-fibre lines through the phone socket need a router with a VDSL modem, which most mesh systems lack.113

The UK provider checklist

PPPoE signs the connection in with a username and password, DHCP or IPoE simply requests an address, and a VLAN is a network tag some lines require.

Why Sky needs extra care

Sky lines authenticate with a method called MER. DrayTek's guide to Sky part-fibre describes a DHCP setting, Option 61, that sends a client identifier when the router connects, and an ordinary router may not offer it.12

Before buying a router to replace a Sky hub outright, get the exact model, firmware and line type confirmed. If better coverage is the goal, mesh units in access-point mode behind the Sky hub are far less adventurous. There are cheaper hobbies than arguing with DHCP on a Sunday.

Privacy: owning the box is not the same as owning the data

eero says its networks do not track the websites you visit, but it does collect device identifiers, bandwidth and performance data. eero units supplied by a broadband provider can share data with that provider, so treat second-hand provider kit with care.21

Nest likewise says it does not collect the content of your traffic or the sites you visit through its Wi-Fi features. It does collect network and device information, and the Google Home app has controls for cloud services and usage statistics.22

Deco, ASUS and Netgear all offer cloud security add-ons, from TP-Link's HomeShield to ASUS's Trend Micro-powered protection and Netgear's Bitdefender-powered Armor. Each has its own terms, so read them before switching on reporting or remote management.679

Whatever the brand, turn on automatic updates, set a unique admin password and put visitors and smart gadgets on a guest network. Virgin notes that modem mode switches off some of its own Wi-Fi monitoring tools.13

What to buy for a flat or a three-bed house

A flat: spend nothing first. Move the hub and test again. If you still need a new unit, the Deco BE25 is the cheapest example here and eero 7 suits people who like a simple app. Neither uses 6GHz.

A three-bed house: compare a two-unit mesh with your provider's own upgrade. The eero 7 pair at £284.99 is the straightforward choice if you can live without eero Plus. The ASUS BT8 pair at £409.99 is the pick, on paper, for 6GHz, VPNs and finer controls.

Run Ethernet between floors if you can, and buy a third unit only once you know where two fall short. A stone cottage and an open-plan new build are different problems.

Ways to pay less

A new mesh is a gadget purchase. The bigger bill is usually the broadband contract underneath it.

Read the end-of-contract notice. Ofcom requires providers to send an end-of-contract notification between 10 and 40 days before your minimum term ends, covering the end date, notice period, the price you pay now and afterwards, and their best available deals. If you are already out of contract, they must remind you every year. Catch: the "best available" deal is theirs; a rival may still be cheaper.23

Haggle or leave when you are free. Out of contract, you can usually switch without an early-termination charge. Ask the retention team to match a written quote before you accept their first offer. Catch: mid-contract exit fees still apply if you leave early for a better deal that is not a qualifying social tariff move.23

Know your mid-contract price-rise rights.

Know your mid-contract price-rise rights. If a rise was clearly set out when you signed, you generally cannot exit penalty-free just because it has landed. If your contract did not say how much the price would rise, or the provider goes further than it promised, it must give at least 30 days' notice and a 30-day window to leave without exit fees. New contracts from 17 January 2025 cannot include inflation-linked or percentage-based rises; older ones may still have them.24

Ask about a social tariff. Ofcom lists cheaper broadband and phone packages for people on Universal Credit, Pension Credit and some other benefits. If your own provider offers one, you can switch to it at any time free of charge. Catch: switching to another company's social tariff mid-contract is not automatically penalty-free; ask for a waiver, and check the speed will still cover the house.25

Fix coverage before you buy kit. Moving the hub and adding a £40 to £80 extender for one dead room is the cheapest path Which? describes. Catch: an extender is not a mesh, and two overlapping networks can confuse phones.4

Keep the hub on a rolling month while you wait for a new-customer fibre deal. A short rolling period bridges the gap without a two-year lock-in. Catch: rolling prices are often higher than a new contract, so diary the switch date.

The verdict

In our view, your own Wi-Fi is worth buying to fix a problem you have measured, or to keep a network that survives switching provider. It is not a compulsory surcharge on decent broadband.

Keep the provider's hub if it does the job, or if your phone line depends on it; add access points if coverage is the problem; and replace the hub only if you want to own the fiddly bits, too.

1. ONT → Own router → Devices
2. Cable hub in modem mode → Own router → Devices. Phone-dependent hub: confirm before replacing.
3. ISP router → Mesh access points → Devices. A DSL line still needs a modem. This drawing is not that case.
