Thick granite walls
Each wall between your phone and the router can weaken the signal. Try the test on either side of the wall.
Test your Wi-Fi speed next to your router — then test your other rooms
Does the match play fine in the hallway but freeze on the living room TV? A speed test measures how quickly this phone can receive and send information where you’re standing. Use the same phone in both spots and compare the two numbers.

Connect to your home Wi-Fi and switch off mobile data. The router is the box that gives your home Wi-Fi. Leave this page open as you walk between rooms.
Step 1: Stand next to your Wi-Fi router first and press TestDownload is how quickly videos and pages reach you. Upload is how quickly you send video on a call. Both are measured in Mbps. A bigger number means more data per second.

Why does your Wi-Fi speed drop so much from room to room?
A newer extension
Foil-backed insulation can interrupt Wi-Fi. That can leave a kitchen extension with a poorer connection than the room next door.
A router at one end
A router in a garage or front hallway has further to reach the back bedroom, garden or shed.
Hallway router vs. plug-in boosters vs. Granite Signal linked Mesh Wi-Fi
| Set-up | What reaches your room |
|---|---|
| Hallway router | One Wi-Fi signal travels from the hallway through every wall on the way. |
| Plug-in booster | It repeats the signal it receives. A socket halfway to the room may work better than one in the dead zone. |
| Linked Mesh Wi-Fi | A cable carries the connection to a Wi-Fi point near your room. Thick walls along the cable route have no effect on that link. |
Get a stronger connection where you watch, work or play
- Show Tom the spot where the match buffers or the call freezes.
- Agree the cable route and fitted price before work starts.
- Repeat the same room test after installation. Granite Signal charges £0 per month for the installed system. Your existing broadband bill continues.
Questions about your home Wi-Fi test
How do I test if my walls are slowing down my Wi-Fi?
Stand beside your router and run the test. Take the same phone to the spot where the problem happens and test again. Keep it on the same Wi-Fi, with mobile data off. A repeatable drop is a clue about coverage. A single reading cannot tell you which wall caused it.
Why am I paying for 500 Mbps or 900 Mbps broadband but only getting under 100 Mbps in other rooms?
Your broadband package describes the connection to your home. Your phone still has to reach the router. Thick walls, distance, other people using the connection and the phone itself can all affect the result. If both rooms are slow, start by checking the connection beside the router again.
Will a plug-in Wi-Fi booster or extender fix a dead zone behind thick walls?
A booster can help if you put it somewhere with a good signal. In a dead zone it may have very little signal to pass on. Try it halfway to the room, then repeat the test in the same spot before buying more equipment.
How does Granite Signal Mesh Wi-Fi work in Aberdeen granite homes and extensions?
We run a discreet cable from the router to a new Wi-Fi point near the rooms that need it. Your phone can use a nearby point without the signal having to cross every wall. We check the result with you after fitting. The installation is a one-off purchase and you keep your broadband subscription.
