How to Improve Slow Wi-Fi at Home: A Simple Guide
Slow Wi-Fi is one of the most common tech frustrations, and one of the easiest to improve. A video call that keeps freezing, a page that takes an age to load, a programme that stops to buffer right at the good bit. Most of the time the cause is simple, and the fix costs nothing.
This guide starts with the quick things that fix most slow Wi-Fi, then explains why it happens and what to do if the trouble is in one particular room. Work through it in order, and stop as soon as things improve. If you are helping an older parent get online, see our wider guide to helping a parent go online.
Quick answer
The single most reliable fix is to switch the router off, wait ten seconds, and switch it back on. It clears most slow patches. After that, move the router somewhere central and out in the open, away from the microwave and cordless phone, and sit a little closer to it. If one far room is always slow no matter what, a mesh Wi-Fi kit spreads the signal further. And if the whole connection is slow everywhere, every day, it may be the broadband itself rather than the Wi-Fi, which is worth raising with your provider.
Quick fixes to try first
1. Turn the router off and on again
It sounds too simple, but this fixes more slow Wi-Fi than anything else. Switch the router off at the wall, count to ten, and switch it back on. Give it a few minutes to start up and settle. Like anything that runs for weeks on end, a router benefits from a fresh start, and this clears out a lot of small hiccups in one go.
2. Move closer to the router
Wi-Fi weakens with distance and through walls. If you are at the far end of the house or out in the garden, the signal may simply be thin where you are sitting. Move into the same room as the router, or one room closer, and see if it picks up. This quick test tells you whether the problem is distance, which points to a clear solution.
3. Give the router a better spot
A router shut inside a cabinet or hidden behind the television is fighting to get its signal out. Stand it up off the floor, somewhere central and open, like a shelf in a main room. Keep it away from the microwave and the cordless phone, which can interfere with it. Often this one change lifts the signal across the whole house.
4. Check what else is using the internet
If several devices are busy at once, each one gets a smaller share. A film streaming in another room, a phone updating in the background, or grandchildren gaming can all slow things down. Try pausing what you can and see if your screen speeds up. It is often not the Wi-Fi at fault, just a busy household sharing one connection.
5. Restart the slow device
If only one phone, tablet or laptop is slow while everything else is fine, the device itself is the likely culprit. Turn it off and on again. This clears whatever it was stuck on, and it is the same gentle fix that sorts out a lot of small device troubles.
Why Wi-Fi gets slow in the first place
It helps to know what is going on. Wi-Fi is a radio signal, so distance, thick walls and other electronics all weaken it. The further you are from the router, or the more walls in between, the slower it feels. A busy household sharing one connection slows everyone down at peak times, usually evenings. And now and then the router just needs that restart. None of it means anything is broken. It is the normal behaviour of a signal doing its best to reach across a house.
When one room is always slow
If a back bedroom, the sleepout or the far end of the house is forever slow no matter what you try, the signal simply is not reaching that far. The usual answer is a mesh Wi-Fi kit. This is a set of two or three small units you place around the house. They work together to carry the signal into the corners the router cannot reach on its own. Officeworks, JB Hi-Fi, Harvey Norman and The Good Guys all sell them, and they are straightforward to set up, or a family member can do it in a few minutes. A plug-in Wi-Fi extender is a cheaper, simpler alternative for a single dead spot.
When it is slow everywhere, every day
If the connection is slow all over the house, all the time, and a restart does not help, the issue may be the broadband itself rather than the Wi-Fi. It is worth calling your provider, who can test the line from their end and tell you whether there is a fault or whether your plan is simply slower than you need. If you are still on the old copper network, this can also be a sign it is time to move to fibre. Our guide on what broadband is explains the difference.
Slow Wi-Fi checklist
- Switch the router off, wait ten seconds, switch it back on.
- Move closer to the router to test whether distance is the problem.
- Stand the router somewhere central and open, off the floor.
- Pause other devices that may be using the connection.
- Restart the one device if only it is slow.
- For a stubborn dead spot, look at a mesh kit or an extender.
- If it is slow everywhere every day, call your provider.

FAQ: Slow Wi-Fi at home
What is the first thing to try when Wi-Fi is slow?
Switch the router off, wait ten seconds, and switch it back on. Give it a few minutes to settle. This clears most slow patches and is the single most reliable fix.
Why is the Wi-Fi fine in one room but slow in another?
Wi-Fi weakens with distance and through walls. A room far from the router, or with thick walls in between, gets a thinner signal. A mesh kit or an extender helps reach it.
Will moving the router really help?
Often, yes. A router that is out in the open, off the floor and away from the microwave reaches further than one shut in a cabinet or behind the television.
What is a mesh Wi-Fi kit?
It is a set of two or three small units placed around the house that work together to carry the signal into rooms the router cannot reach alone. They are sold at the main electronics retailers and are easy to set up.
When should I call my provider?
If the connection is slow everywhere, every day, and a restart does not help. They can test the line and tell you whether there is a fault or your plan is slower than you need.
