How we test wi-fi routers and extenders

How we test real-home testing

To assess performance in a 'real-home' scenario, we simultaneously stream 4K video from Netflix, 1080p HD video from YouTube, audio and transfer online files at different locations around the home. We then monitor each device and see how well each multimedia app is displaying video or playing audio and record the file transfer speed. This shows how well the router will cope under an everyday, relatively light load. We understand that every wireless network and its environment are different, but this is how we accurately compare routers and extenders for multimedia performance.

Coverage

How we test coverage

To assess wireless coverage we record throughput at multiple different locations around the test house and average this.

Stress test

Single device

How we test stress test

To push the router or extender to the limits and test how well it copes with single vs. multiple devices, we record file transfer speed at multiple locations around the home - both with a single devices connected to the network and with multiple devices working simultaneously.
