Quick answer
Before buying a router, check whether the bottleneck is router coverage, broadband speed, device capability, ISP equipment or home layout. A new router does not fix every WiFi problem.
What to check
- Run wired and WiFi speed comparisons where possible.
- Check whether slow performance affects all devices or one device.
- Confirm ISP modem/router compatibility and login requirements.
- Review WiFi generation support across current devices.
- Map coverage gaps before choosing router, mesh or extender.
Trade-offs
A stronger router may help central coverage, but mesh may suit larger or thicker-walled homes. ISP restrictions can also limit replacement choices.
Before you buy
Check current manufacturer specifications, router or laptop compatibility notes, warranty and return terms before ordering. This guide does not provide live pricing, service guarantees, installation advice or first-hand test claims.
