Compare Wi-Fi Performance Room by Room
Use the same device to test your internet speed in different rooms, record the results below and compare them with a measurement near your router. This browser tool compares performance, not radio signal strength.
Room-by-room comparison
Test your Wi-Fi room by room
Start beside your router, then repeat with the same laptop or tablet in each room. Select a location once, run the automatic test or enter a reading manually, and compare your saved results.

Run a Wi-Fi speed test in this room
Test directly on this page, without large dials. Download, upload, ping and jitter are measured automatically.
Select a room above to enable the test.
Completed tests are added to your room comparison automatically. Anonymous measurements, without room names, are sent to LinkSpeed's test database. A full test uses substantial data and may take longer on weak Wi-Fi. Your browser connects to Cloudflare for the measurement.
Enter a reading manually insteadOptional · Use results from another speed test
Use the room selected above and enter the results of a speed test you ran elsewhere. Manual entries stay on this device and are not submitted to the national test database.

Start by testing beside your router.
Results are measurements, not Wi-Fi signal strength. Before/after changes can reflect interference, network load or equipment placement; confirm improvements with repeat tests.

What a weak Wi-Fi room result tells you
First, improve coverage for free
Move your router away from cupboards, thick walls, floors and metal objects. Try a more central position and repeat the same device test. If available, compare 2.4GHz and 5GHz bands carefully—2.4GHz often reaches further, while 5GHz can offer better throughput nearby.
Know when hardware may help
If only distant rooms are poor and Ethernet is fast, a properly placed mesh node or wired access point may help. If every room is slow and a wired connection is also slow, a new mesh system is unlikely to solve the underlying broadband problem.
Found a weak room? This tool records the difference; the Wi-Fi slow in one room guide explains how to fix a local dead zone. If the slowdown mainly affects another floor, follow Wi-Fi slow upstairs troubleshooting for floor, landing and backhaul checks.
Compare fixes after testing
Find out when a mesh kit, wired access point or extender makes sense. Consider Ethernet backhaul and placement before purchasing anything.

Questions about Wi-Fi dead zones
Does this read actual Wi-Fi signal strength or nearby networks?
No. Websites are not normally permitted to read Wi-Fi RSSI, radio channel or nearby networks. This tool compares browser speed-test results measured here or entered manually. It cannot diagnose exact signal strength from your browser.
How can I make the comparison fair?
Use one device and the same test method in each room, keep the device in a similar position, avoid large background downloads, and repeat unexpected results. Use the first near-router reading as your baseline.
Is a mesh system always the answer?
No. Simple router repositioning, a wired access point or replacing a faulty cable may work better. If Ethernet is also slow, check the broadband line and router first.
