Where to put your router for the best Wi-Fi

The best router placement is central, high and in the open: roughly in the middle of the area you want to cover, on a shelf or table rather than the floor, and away from metal, water and big appliances. Small changes in router placement often help more than any setting. If the router has to stay near the socket where your broadband comes in, a longer cable can give you freedom.

Why router placement matters so much

A router sends signal out in all directions, a bit like a light bulb. Every metre and every obstacle the signal crosses costs strength. Put the bulb in a cupboard in the corner and the far rooms stay dark. Put it in the middle of the room, up high, and light reaches everywhere more evenly.

Wi-Fi also works both ways. Your phone or laptop must send signal back, and its radio is far weaker than the router's. So the router needs to be close enough to hear your devices, not just loud enough to reach them.

The router placement rules that matter most

These six rules cover nearly every home. You do not need all of them; each one you follow helps a little.

1. Go central

Place the router as close as you can to the middle of your home, or the middle of the rooms where you use Wi-Fi most. A router by the front door of a long house sends half its signal into the street.

2. Go high

Signal spreads out and slightly down from most routers. A shelf, the top of a bookcase or a wall mount usually beats the floor. On a two-storey home, a high spot on the ground floor or a low spot upstairs can cover both floors better.

3. Keep it in the open

Cupboards, drawers, TV cabinets and the space behind the sofa all block signal. Leave clear air around the router, and do not stack things on top of it, which also helps it stay cool.

4. Avoid metal and water

Metal reflects Wi-Fi and water absorbs it. Keep the router away from:

• radiators, metal shelving and filing cabinets
• mirrors, which often have a metal backing
• fridges, washing machines and dishwashers
• fish tanks and large plants

5. Keep away from other electronics

Microwaves, some cordless phones, baby monitors and wireless speakers can interfere, especially on 2.4 GHz. A gap of a metre or two helps. Do not put the router directly next to a TV or games console with lots of cables either.

6. Point the antennas sensibly

If your router has adjustable antennas, a mix often works best: some straight up and some tilted to the side. Upright antennas spread signal well across one floor; angled ones can help reach floors above and below. Try a few positions and measure.

When the router has to stay put

Often the router sits where the broadband line enters the home, which is rarely the middle of the house. You still have options:

1. Use a longer cable. A longer network cable from the provider's box, or a longer phone or fibre cable fitted properly, can let you move the router to a better spot. Check with your provider before moving any line they installed.
2. Raise it. Even if it must stay in the same room, a high shelf beats the floor.
3. Open it up. Move it out of a cupboard or from behind a TV.
4. Add a second unit. Use the router where it is and add a mesh point or wired access point where coverage is needed. Mesh Wi-Fi vs a range extender explains the choices.

How to test a new position

Do not rely on bars. Measure.

1. Note the Wi-Fi signal in dBm in each room with the router where it is now.
2. Move the router to the new spot and wait for it to fully start up.
3. Walk the same route with the phone held the same way and note the readings again.
4. Run a speed test in the two or three rooms that matter most.
5. Keep the position that gives the best results where you actually use Wi-Fi, not just the best number next to the router.

If one room stays weak whatever you do, it may be a true dead zone. How to find and fix Wi-Fi dead zones covers the next steps.

Placement and channel go together

Once the router is in a good spot, check the channel. A strong signal on a crowded channel can still feel slow in the evening. How to find the best Wi-Fi channel shows how to check.

How CellRadar helps

CellRadar's Wi-Fi Meter shows a live strength gauge, so you can compare router placement options in each room with real numbers. The Dead-zone Walk Map colours each spot in a room by its measured signal, which makes before-and-after comparisons easy. The Wi-Fi Analyzer then shows whether your channel is crowded once the router is in place.

Frequently asked questions

Is it better to put the router upstairs or downstairs?

It depends on where you use Wi-Fi most. In many two-storey homes, a high spot downstairs or a low spot upstairs, near the middle of the house, covers both floors best.

Does a router work better standing up or lying flat?

Follow the maker's design. Routers built to stand upright usually spread signal best that way, and lying them flat can change their coverage.

How far should my router be from the microwave?

A few metres is sensible. Microwaves can disrupt 2.4 GHz Wi-Fi while they run, so keep the router out of the kitchen if possible.

Can I hide my router behind the TV?

You can, but it will weaken the signal. TVs contain metal and lots of electronics, so a shelf beside or above the TV is a better choice.
