Most broadband complaints are not about the broadband itself. They are about WiFi — specifically the gap between what your router can theoretically deliver and what actually arrives at the device you are trying to use. Dead zones, weak signals in certain rooms, connections that drop mid-call, and speeds that vary dramatically depending on where you are in the house are all WiFi problems, not necessarily broadband problems. The good news is that most of them are fixable.
Before making any changes, run a speed test with your device connected directly to the router via an ethernet cable. If the wired speed matches what you are paying for — or close to it — then your broadband is working correctly and the issue is WiFi distribution. If the wired speed is also slow, the problem is upstream of your router and a different set of solutions apply.
Most people discover their broadband is fine and their WiFi distribution is the bottleneck. This is a much easier problem to solve.
WiFi signals degrade with distance and are blocked or reflected by solid objects. In a typical UK home, the main obstacles are:
This is the most effective single change most people can make — and it costs nothing. A router placed in a corner, inside a cupboard, or on the floor of a hallway will deliver a fraction of its potential range. WiFi signals radiate in all directions, so a router positioned centrally in your home — ideally on a shelf at mid-height in the most-used room — will cover significantly more of the property.
Practical tips for router placement:
For your most important device — typically a work computer or games console — a direct ethernet connection from router to device eliminates WiFi variables entirely. This is not always practical, but where a cable can be run discreetly along a skirting board or through a floor, it is the most reliable solution available. Ethernet delivers the full speed of your connection with zero interference.
In areas with many overlapping WiFi networks — flats and terraced housing particularly — your router may be competing on a congested channel. Most modern routers allow you to manually select a WiFi channel or use automatic channel selection. The 5 GHz band (faster but shorter range) and 2.4 GHz band (slower but longer range) both have multiple channels. Switching to a less congested channel can produce noticeable improvements without any hardware changes.
Most router admin panels can be accessed by typing your router's IP address into a browser. The address is usually printed on the router itself — typically 192.168.0.1 or 192.168.1.1.
A WiFi extender picks up your existing signal and rebroadcasts it, extending coverage into rooms the router cannot reach directly. They are inexpensive (typically £20–£40) and easy to set up. The limitation is that they create a separate network name, can halve available bandwidth on the extended network, and only work well if they are placed where the original signal is still reasonably strong — roughly halfway between the router and the dead zone.
Extenders are a reasonable short-term solution for occasional use in a specific room, but they are not the best answer for homes where multiple rooms have coverage issues.
A mesh system replaces your single router with two or more nodes that work together to create a seamless single network across your whole home. Unlike extenders, mesh nodes use a dedicated backhaul channel to communicate with each other, which means they do not halve your bandwidth. Your devices move between nodes automatically as you move around the house.
Well-regarded mesh systems for UK homes include the TP-Link Deco range, Eero and Google Nest WiFi. A two-node system typically covers most UK three- or four-bedroom houses effectively. Three nodes are worth considering for larger properties, homes with thick walls, or buildings across multiple floors.
Mesh systems typically cost £80–£200 for a starter pack, depending on the brand and specification. For homes where WiFi coverage is a persistent frustration, this is usually the most impactful investment available.
Powerline adapters use your home's electrical wiring to carry a network signal between rooms. You plug one adapter into a socket near your router and connect it with an ethernet cable, then plug a second adapter in the room where you need connectivity — either connecting directly with ethernet or using the adapter's built-in WiFi.
Powerline adapters work well in some homes and poorly in others, depending on the age and quality of the electrical wiring. In houses built after the 1980s with modern ring mains they typically perform well. In older properties with more complex wiring they can be inconsistent. Avoid plugging powerline adapters into extension leads or surge protectors — they must connect directly to a wall socket to work reliably.
If you have tried the steps above and speeds are still poor or inconsistent, the problem may be your broadband connection itself rather than WiFi distribution. Common causes include:
If you are not sure whether the issue is your setup or your connection, the fastest way to find out is the wired speed test described at the start of this guide. Plug in directly, run the test, and compare the result to what your package promises.
