A fast internet package does not automatically mean fast Wi-Fi everywhere in a building. Broadband and Wi-Fi are related, but they are different parts of the connection, and identifying which one is causing the problem is the first step.
Test the broadband connection separately
Where possible, connect a computer directly to the router with Ethernet and run a speed test. This helps establish what the internet connection itself can deliver without Wi-Fi coverage, interference or the client device affecting the result.
Improve Wi-Fi coverage
Router and access-point position matters. Thick walls, foil-backed insulation, metalwork, floors and neighbouring networks can all reduce performance. For larger homes and business premises, multiple properly positioned access points are usually more effective than trying to cover everything from one router.
Use wired backhaul where possible
Connecting access points back to the network using Ethernet generally gives more predictable performance than relying on wireless repeating. Structured cabling can also provide reliable connections for desktop PCs, TVs, CCTV, printers and other fixed equipment.
Mesh Wi-Fi, repeaters and powerline
These technologies can be useful, but results depend heavily on the property. Mesh systems work best when nodes have a good connection between them. Repeaters can improve coverage but may reduce usable throughput. Powerline performance depends on the electrical installation and can vary considerably between buildings.
4G and 5G broadband
Mobile broadband can be a useful primary or backup connection where fixed-line service is poor. An external antenna and suitable router can make a substantial difference in locations with weak indoor mobile signal, but performance depends on local network coverage and congestion.
What about Starlink?
Starlink can be a useful option for rural homes, farms, workshops and commercial premises where fibre or good fixed broadband is unavailable. Because it uses low-Earth-orbit satellites, latency is substantially lower than traditional geostationary satellite broadband. The dish needs a clear view of the sky, and a good internal network and Wi-Fi system is still important once the connection reaches the building.
Starlink can also be considered as a secondary internet connection where resilience is important.
Plan the network, not just the internet connection
If a speed test beside the router is good but devices elsewhere are slow or unreliable, upgrading the broadband package may not solve the problem. Wi-Fi assessment, access-point placement, cabling and network configuration may be the real answer.
