How to make Wi-Fi faster on my phone (2026)
Quick Answer
To make Wi-Fi faster on your phone, first work out whether the slowdown is caused by your phone, your router, or your internet connection. The most effective fixes are usually moving closer to the router, restarting the phone and router, reducing interference, updating software, and using the right Wi-Fi band if your router offers more than one.
Overview
Slow Wi-Fi on a phone is often caused by a small number of issues: weak signal, congestion on the network, router problems, phone settings, outdated software, or an internet service fault. The quickest way to improve speed is to test methodically instead of changing lots of settings at random. Start by checking whether the problem only affects one phone or every device in the home. If every device is slow, the issue is more likely to be with the router, placement, interference, or your broadband service. If only your phone is slow, focus on the phone itself: restart it, forget and rejoin the Wi-Fi network, disable power-saving features that may restrict background network activity, and make sure the operating system is up to date. Physical location matters more than many people expect: walls, metal objects, large appliances, and distance can all weaken the signal. Network congestion also matters, especially if many devices are streaming, gaming, or backing up files at the same time. If basic fixes do not help, check your router settings using the manufacturer’s instructions, and consider whether your home needs better coverage through improved router placement or additional Wi-Fi equipment. If the connection drops often, stays slow on all devices, or the router appears faulty, it may be time to contact your broadband provider or a local IT professional.
Who this is for
Phone users who want faster, more reliable Wi-Fi at home, including people troubleshooting slow browsing, buffering, app downloads, or poor video calls.
What you’ll need
- your phone
- access to your Wi-Fi network password
- access to your router
- your router manufacturer's app or manual if available
- a second device for comparison if possible
Before you start
Check whether mobile data is also slow. If both mobile data and Wi-Fi are poor, the issue may be with the phone rather than your home network. Also check whether other devices on the same Wi-Fi are slow, because that tells you whether to focus on the phone or the router and internet service.
Step-by-step
- 1
Check whether the problem is only on your phone
Test the Wi-Fi on another device in the same place, such as a laptop or another phone. Then test your phone in a different room and, if possible, on a different Wi-Fi network such as at work or a friend's home.
Why: This separates a phone-specific issue from a home network issue. It prevents you wasting time changing router settings when the real cause is the phone, or vice versa.
- 2
Restart your phone and your router
Restart your phone normally. Then restart the router using its normal power or restart method described by the manufacturer, and wait for it to reconnect fully before testing again.
Why: A restart clears temporary glitches, stuck connections, and memory issues on both the phone and the router.
- 3
Move closer to the router and reduce interference
Test your phone near the router. If speed improves, the issue is likely weak signal or interference. Keep the router in an open, central position, away from thick walls, metal objects, microwaves, cordless phone bases, and large electronics.
Why: Wi-Fi speed drops when signal strength is low or radio interference is high. Router placement often makes a bigger difference than settings changes.
- 4
Forget the network and reconnect
On your phone, remove or 'forget' the Wi-Fi network, then reconnect using the correct password. If your phone has Wi-Fi assist, smart network switching, private address, or similar connection features, leave them at their default settings unless you know they are causing a problem.
Why: Rejoining the network can clear corrupted connection details or a poor saved profile without changing the rest of your setup.
- 5
Update your phone and router software
Install any available operating system updates on your phone. Check the router manufacturer's instructions for firmware updates and apply them if available.
Why: Updates can fix known Wi-Fi bugs, security issues, and compatibility problems that affect speed and stability.
- 6
Check for network congestion
Pause large downloads, cloud backups, video streaming, gaming, or software updates on other devices and test again. If your router supports separate Wi-Fi bands, use the one recommended by the manufacturer for your device and distance from the router.
Why: Too many active devices share the same wireless airtime and internet bandwidth, which can make your phone seem slow even when the signal is good.
- 7
Reset network settings if your phone is still the only slow device
Use your phone's network settings reset option if available. This will usually remove saved Wi-Fi networks and some connection preferences, so make sure you know your Wi-Fi password first.
Why: This can clear stubborn configuration problems when ordinary reconnecting has not worked.
- 8
Escalate if the issue affects all devices or keeps returning
If every device is slow, contact your broadband provider to check for line faults or outages. If coverage is poor in parts of the home, review the router placement and consider a mesh system or an additional access point installed according to the manufacturer's guidance.
Why: Persistent whole-home problems are often outside the phone itself and may need network changes or provider support.
Why this works
Phone Wi-Fi performance depends on three things working together: a healthy internet connection, a stable router, and a strong local wireless signal. Diagnosing which part is failing lets you choose the right fix instead of relying on trial and error.
Common mistakes to avoid
- Testing speed in only one room and assuming the whole network is slow
- Changing many router settings at once, making it hard to tell what helped
- Placing the router behind a television, inside a cupboard, or on the floor
- Ignoring other devices that may be using lots of bandwidth
- Forgetting that old software on the phone or router can cause Wi-Fi problems
Troubleshooting
Wi-Fi is fast near the router but slow in other rooms
Improve router placement first. If that is not enough, consider better home Wi-Fi coverage such as a mesh system or additional access point.
Only one phone is slow but other devices are fine
Restart the phone, forget and rejoin the network, update the phone software, and reset network settings if needed.
All devices are slow on Wi-Fi
Restart the router, reduce network congestion, check for outages with your broadband provider, and update the router firmware if the manufacturer provides one.
Wi-Fi connects but pages and apps stall or buffer
Test another device. If all devices stall, the broadband connection may be unstable. If only your phone stalls, disable any active VPN, restart the phone, and test again.
Phone keeps dropping off Wi-Fi
Check signal strength and interference, update phone and router software, and reconnect to the network. If the issue happens on multiple networks, the phone may need technical support.
Speed is poor at busy times of day
This may be local network congestion in your home or a broadband capacity issue. Reduce heavy usage on your own network first, then contact your provider if the pattern continues.

Alternatives
- Use mobile data temporarily if your home Wi-Fi is the issue
- Use a different trusted Wi-Fi network to confirm whether the problem is location-specific
- If available, use a wired connection for stationary devices so the phone has less wireless congestion
Pro tips
- If your phone has a thick case with metal components or accessories attached, remove them briefly for testing in case they affect signal reception.
- Run tests in the same location each time so your results are comparable.
- If your router has a companion app, use it to check connected devices and pause heavy users while you test.
- Keep your router out in the open rather than hidden behind furniture.
Safety notes
- Do not open the router casing unless the manufacturer specifically instructs you to do so.
- If you need to move the router, avoid straining cables or placing it where it could overheat.
- Only install firmware from the router manufacturer's official source.
