To improve home wifi, move the router to a central, open spot, restart it, update its firmware and connect devices to the right band. These free steps fix many weak-signal complaints. If dead zones remain, a mesh system or a wired access point is a better answer than a cheap plug-in extender.
First, Find the Real Problem
Slow internet and weak Wi-Fi are different things. Test your speed with a laptop plugged directly into the router with a cable. If that is slow too, the issue is your internet plan or provider, and better Wi-Fi will not change it. If the cable test is fast but wireless is slow in some rooms, the signal is what needs help.
Fixes That Cost Nothing
Move the router
Radio signal weakens through walls, floors, mirrors, metal and water. Place the router high, in the middle of the home, and out in the open instead of inside a cabinet or behind the television. A router in the corner of the house sends much of its signal into the garden.
Keep interference away
Microwave ovens, cordless phones and baby monitors can disturb the signal. So can a thick fish tank or a stack of metal shelving. Give the router a little breathing space from these things.
Restart it and update it
Rebooting clears small faults. Log in to the router’s settings page, or use its app, and install any firmware update. Updates often improve stability and security.
Use the right band
Most modern routers broadcast more than one band. The 2.4 GHz band reaches farther but is slower and more crowded. The 5 GHz band is faster over shorter distances. Place streaming and gaming devices close to the router on 5 GHz, and let far-away smart plugs and sensors use 2.4 GHz.
Change the channel
In an apartment block, many neighbouring networks compete for the same channels. Most routers choose automatically, but if yours seems slow in the evening, try a different channel in the settings or run auto-selection again.
Choosing Between Hardware Fixes
| Option | Best for | Drawback |
|---|---|---|
| Plug-in range extender | One small dead spot, tight budget | Often halves speed on the extended signal |
| Mesh system | Larger or multi-floor homes | Costs more; quality varies |
| Wired access point | Best performance where cables can run | Needs ethernet wiring |
| Powerline adapters | Homes where running cable is hard | Depends on your home’s electrical wiring |
| New router | Routers many years old | Will not fix poor placement |
If you can run an ethernet cable to a stubborn room, that is nearly always the most reliable fix. Even one wired link to a second access point can transform a large house.
Security Counts Too
An open or weakly protected network invites freeloaders who slow you down and may snoop. Use the strongest encryption your router offers, usually WPA3 or WPA2, and set a unique Wi-Fi password and a different admin password. A guest network keeps visitors and smart gadgets away from your computers. The same habits are covered in our cybersecurity basics guide.
Note: Router menus differ between brands. Check your manual or your provider’s help pages before changing settings you do not recognise.
Reduce the Load
A busy household can overwhelm a basic router. If several people stream video, join calls and download updates at once, everything feels slower. Wire the desktop, television or console by cable where you can, which frees the wireless airtime for phones and tablets. If you add many connected gadgets, our smart home guide for beginners explains how to plan the network for them.
When It Is Time to Replace the Router
A router that is many years old, drops connections often, or no longer receives updates deserves retirement. Check whether your provider supplies replacements free of charge before buying. When shopping, focus on coverage for your home’s size and the number of devices, rather than the biggest speed number on the box.
Reading the Signs in Your Own Home
Test rather than guess. Walk through your home with a phone and a free signal or speed-test app, noting the rooms where the numbers fall. A pattern often appears: the signal drops sharply behind a brick chimney, a large mirror or a utility room with metal pipes. Knowing where the weak points are helps you decide whether a new position is enough or you need extra hardware.
Antenna direction can matter too. If your router has adjustable external antennas, try pointing one vertically and one horizontally to cover floors above and below as well as the same level. Small experiments like these cost nothing and can be repeated until the results stop improving.
Finally, think about the placement of the connected devices themselves. A television or console that sits far from the router is the best candidate for a cable.
Your Saturday Wi-Fi Checklist
Run a wired speed test first, then a wireless one in your worst room, and write both numbers down. Move the router to a better spot, reboot it, update it and switch your key devices to the right band. Test the same room again. If it is still weak, price one wired access point or a mesh kit.

Frequently asked questions
Where is the best place to put a Wi-Fi router?
Somewhere central, high up and in the open, away from thick walls, metal objects and appliances. Avoid cabinets and floors.
Do Wi-Fi extenders work?
They can help a single dead spot, but they often cut speed on the extended signal. A mesh system or a wired access point is usually more reliable.
What is the difference between 2.4 GHz and 5 GHz?
2.4 GHz reaches farther but is slower and more crowded. 5 GHz is faster but covers a shorter distance.
How often should I restart my router?
You do not need a strict schedule. Restart it when you notice problems, and install firmware updates as they appear.
Will a new router make my internet faster?
Only if the old one is the bottleneck. Your internet speed is set by your plan, so test with a cable first to find out.
