If your Wi-Fi keeps disconnecting every few minutes, you're not imagining it, and you're definitely not alone. Dropped connections usually come down to a handful of common culprits: interference, outdated software, overworked hardware or settings that are quietly working against you. The good news is most of these fixes take just a few minutes.
Below we've ordered the list from quickest wins to slightly more involved fixes, so work through them in order rather than jumping straight to buying new gear.
1. Restart Your Router and Modem
This sounds obvious, but it fixes a surprising number of problems. Routers are small computers, and like any computer, they can get bogged down with memory leaks or temporary glitches after weeks of running non-stop.
Unplug both the router and modem, wait about 30 seconds, then plug the modem back in first. Give it a minute or two to reconnect before powering the router back on. This clears temporary errors without touching any of your settings.
If your Wi-Fi keeps disconnecting right after a restart, the problem likely lies elsewhere on this list.
2. Check for Physical Obstructions and Distance
Wi-Fi signals weaken as they pass through walls, floors and furniture. Thick materials like brick, concrete and metal are the worst offenders, while glass and plasterboard cause less trouble.
Try moving closer to the router to see if the dropouts stop. If they do, you've found your answer, and it's time to think about positioning rather than hardware faults.
Microwaves, baby monitors and some Bluetooth devices can also interfere with the 2.4GHz band specifically. Keep your router away from these where possible.
3. Switch to a Different Wi-Fi Channel
Wi-Fi channels are a bit like lanes on a motorway. If everyone in your block of flats is using the same one, you'll get congestion and dropped packets.
Most modern routers choose channels automatically, but it's worth checking your router's admin settings to confirm. Switching between channels 1, 6 and 11 on the 2.4GHz band often helps, since these don't overlap with each other.
If you're not sure how to access these settings or want a wider overview of channel and interference issues, our guide on why your Wi-Fi might be slow covers this in more depth.
4. Turn Off Wi-Fi Power-Saving Settings
Laptops and phones often have power-saving modes that reduce how much energy the Wi-Fi adapter uses. The trade-off is that your device checks in with the router less frequently, which can cause it to drop the connection or feel sluggish.
On Windows, you'll find this under the network adapter's advanced power management settings. On a Mac or Linux machine, check the energy saver or power settings menu. Turning this off, especially while plugged into mains power, often stops random disconnects.
This is particularly common on laptops that seem fine when charging but lose Wi-Fi constantly on battery.
5. Update Your Device's Network Drivers
Outdated drivers are one of the most overlooked causes of a Wi-Fi connection that keeps disconnecting. Manufacturers release updates to fix bugs, including ones that affect wireless stability.
On Windows, go to Device Manager, find your network adapter, and check for updates there or via the manufacturer's website. Mac updates usually come bundled with macOS system updates, so make sure you're not several versions behind.
It's easy to forget this step because the device still "works", just unreliably. A five-minute driver update can solve problems that have been bothering you for weeks.
6. Update Your Router's Firmware
Routers run their own software too, and it needs updating just like anything else. Firmware updates often patch stability bugs, improve how the router handles multiple devices, and sometimes fix specific disconnection issues reported by other users.
Log into your router's admin panel (usually through a browser at an address like 192.168.1.1) and look for a firmware or software update section. Some routers do this automatically, but many still require a manual check.

7. Reduce the Number of Connected Devices
Every device connected to your network takes a small slice of its capacity. Smart plugs, cameras, speakers and streaming sticks all add up, and older routers can genuinely struggle once you pass a certain number of devices.
Check your router's connected devices list and see if anything unexpected is online. Smart home kit is a common culprit here, especially if several devices are polling the network constantly.
If you're building out a smart home setup, it's worth reading our guide on setting up Wi-Fi for smart home devices to understand how to keep things running smoothly as you add more gadgets.
8. Check for Wi-Fi Interference from Neighbours
In flats and terraced houses, overlapping networks are a frequent cause of instability. Your neighbour's router broadcasting on the same channel and frequency as yours creates a kind of background noise that both networks have to fight through.
Apps that scan nearby networks (available for both phones and laptops) can show you how crowded your local airwaves are. If there's a lot of overlap, switching to the 5GHz band, which has a shorter range but much less congestion, often helps.
This is also a good moment to check your network's security settings. An unsecured or poorly secured network can attract unwanted freeloaders, which adds load and instability. Our guide on securing your home Wi-Fi network walks through the basics.
9. Check Your Internet Service Provider's Connection
Sometimes the problem isn't your Wi-Fi at all, it's the connection coming into the house. A faulty line, an ageing cable or an area-wide fault can all cause intermittent drops that look like Wi-Fi problems.
Connect a device directly to the modem with an ethernet cable and see if the connection still drops. If it does, the issue sits upstream of your router, and it's worth contacting your provider.
Many ISPs have status pages or apps that show known outages in your area, which can save you a frustrating call if the fault is already being fixed.
10. Consider Whether Your Router Needs Replacing
If you've worked through everything above and your Wi-Fi keeps disconnecting regardless, the router itself may simply be wearing out. Routers typically last three to five years of reliable use before internal components start to degrade, especially if they're never switched off.
Signs of a failing router include random reboots, LED lights behaving oddly, overheating, or connections that drop no matter how close you are. If your router is several years old and struggling with more devices than it was designed for, an upgrade is often the simplest fix.
Before buying anything, it's worth reading up on what actually matters in a new router, since specs and marketing terms vary wildly between brands. If you're also curious about building a more capable home network setup down the line, our guide to starting a home lab is a good next step once the basics are sorted.
Conclusion
Most cases of Wi-Fi that keeps disconnecting come down to something fixable: interference, outdated drivers, firmware that needs updating, or simply too many devices competing for bandwidth. Working through these fixes in order, from a quick restart to checking your router's age, will solve the vast majority of dropout problems without any guesswork.
If you've tried everything and the issue persists, it's worth considering whether your layout needs a signal boost rather than a full router replacement. Extending coverage properly can often solve what looks like a connection problem but is really just patchy signal in certain rooms.
FAQ
Why does my Wi-Fi disconnect every few minutes?
This is usually caused by interference, an overloaded channel, power-saving settings on your device, or outdated drivers and firmware. Working through fixes from easiest to most involved will usually identify the cause.
Does restarting the router actually help?
Yes, it clears temporary software glitches that build up over time. It won't fix a hardware fault, but it rules out a lot of common causes quickly.
Is 5GHz better than 2.4GHz for stability?
5GHz generally has less interference and congestion, though it has a shorter range. If your devices are close to the router, switching to 5GHz can noticeably reduce dropouts.
How do I know if my router is failing rather than just misconfigured?
If you've updated firmware, changed channels and ruled out interference, but the router still disconnects randomly or overheats, that points to a hardware issue rather than a settings problem.
Can too many smart home devices cause disconnections?
Yes, particularly on older routers. Each device adds a small load to the network, and some smart home gadgets communicate more frequently than you'd expect, which can strain weaker hardware.
Should I contact my ISP before replacing my router?
It's a sensible first step, especially if a wired connection to the modem also drops. This rules out a line fault or area outage before you spend money on new hardware.
