If your WiFi keeps disconnecting, the fault is in one of three places — the device that drops, the router, or the line coming into your home — and one quick test tells you which: check whether other devices drop at the same moment. If every device loses WiFi together, work on the router and the line, not on your laptop or phone. If only one device drops while the rest stay connected, work on that device: forget the network and rejoin it, restart it, and update its software and WiFi driver. Work through the sections below in that order and you will fix most cases of WiFi disconnecting randomly without changing any setting you did not need to touch.

First, work out what is actually dropping

Before changing anything, watch one disconnect happen and answer three questions.

Does everything drop, or just one device? When the WiFi drops, pick up a second device straight away. If it has also lost the connection, the router or the internet line is the problem, and no setting on your laptop will fix it. If the second device is fine, the problem lives in the device in your hand. This single split — all devices versus just one device — decides which half of this article you need.

Does the WiFi itself drop, or only the internet behind it? Look at the WiFi icon when it fails. If the icon shows you still connected to your network but pages will not load, the wireless link is holding and the fault is further up — router, modem or provider. If the icon shows the network gone entirely, the wireless link itself is breaking, which points at signal, interference or the device’s WiFi hardware and driver.

Is there a pattern? Drops at the same time each day suggest a router restart schedule, a provider fault, or interference from something that switches on then — a microwave is the classic example on the 2.4 GHz band. Drops in one room suggest weak signal; drops after the laptop wakes suggest a power or driver problem on that laptop. Note the pattern down — if you call your provider, it is the most useful thing you can give them, and on Windows, how to screenshot on Windows covers capturing the exact error message to send with it.

Fixes when only one device keeps disconnecting

Work through these on the dropping device only, in order. Stop when the connection holds.

Restart the device, then forget and rejoin the network

A plain restart clears more of these faults than people expect. On a Mac, Apple’s own WiFi guide puts restarting near the top of its list, partly because the Mac renews the internet address the router gave it when it restarts.

If the drops continue, make the device forget the network and join it fresh. Forgetting deletes the saved copy of the network — including an old password or settings left over from before a router change — and the rejoin rebuilds it cleanly.

  • Windows: Settings > Network & internet > Wi-Fi > Manage known networks, select your network, select Forget, then reconnect from the WiFi list and enter the password. This is a step in Microsoft’s Fix Wi-Fi connection issues in Windows guide.
  • Mac: System Settings > Wi-Fi, find the network, remove it from the known networks list, then rejoin and re-enter the password. Apple also advises checking the Wi-Fi menu for a Wi-Fi Recommendations item — if your Mac has detected a specific problem, it says so there.
  • iPhone: Settings > Wi-Fi, tap the info button next to your network, then tap Forget This Network, as described in Apple’s iPhone Wi-Fi settings guide. Rejoin and enter the password again.
  • Android: Settings menus differ by maker, but the route is generally Settings > Network & internet (or Connections) > Wi-Fi, open the saved network, and choose Forget, then rejoin. Because Android menus genuinely differ between Samsung, Pixel and other phones, follow the wording on your own phone rather than any single written path.

You need the WiFi password before you forget the network. If you do not have it, get it first — from the router label, from another device already connected, or from whoever manages the network.

Run the built-in troubleshooter and diagnostics

On Windows 11, Microsoft’s first instruction is to run the automated Network and Internet troubleshooter in the Get Help app; it checks the adapter, the driver and the connection settings, and fixes some faults itself. On a Mac, hold the Option key, click the WiFi icon, and open Wireless Diagnostics — Apple’s built-in tool for exactly this kind of repeated drop. Neither tool fixes everything, but both are free, quick, and can name the fault instead of leaving you guessing.

Update the system and the WiFi driver

Out-of-date software is a steady cause of one-device drops, especially drops that started right after — or right before — a system update. Install pending system updates first. On Windows, if the problem survives, Microsoft’s guide gives a stronger step: uninstall the network adapter driver in Device Manager and restart, after which Windows reinstalls the driver automatically. Two cautions from that same guide matter. Download the latest driver from your PC maker’s website first and keep it as a backup — if the PC has no internet, download it on another device and copy it across on a USB drive. And treat driver uninstalling as a later step, not a first one: try everything above it first.

Power settings deserve one check on a laptop that drops after sleep. Some laptops reduce power to the wireless adapter to save battery, and the adapter does not always recover cleanly on waking. If your drops line up with waking the machine, that setting — usually in the adapter’s properties or the maker’s power app — is worth reviewing. Makers place it differently, so check your own model’s support page rather than following a path written for a different brand. If, instead, only websites fail in one browser while apps and other browsers work fine, the WiFi is probably innocent — a stale browser store is a likelier cause, and how to clear cache covers that separate fix.

WiFi keeps disconnecting on a phone

On a phone, work through the same order: restart the phone, forget and rejoin the network, install system updates. Then check the settings that make a phone leave WiFi on purpose. Phones have features that switch to mobile data when WiFi looks weak — on an iPhone this appears in Wi-Fi settings as an assist option, and Android phones have similar “switch to mobile data” behaviour under different names. If your phone drops WiFi whenever the signal dips for a second, that feature may be doing exactly what it was designed to do, in a home where the signal has genuine weak spots. The real fix is then the weak spot itself — see the router placement section below — rather than the phone.

One more phone-specific check: a VPN app or security app that reconnects badly can look exactly like WiFi dropping. If the drops started when such an app was installed, turn it off for a day and compare.

Fixes when every device disconnects: the router

If all your devices drop together, leave their settings alone. The problem is the router, the modem, or the line.

Restart the router properly

Turn the router off, unplug it, wait at least 30 seconds, and plug it back in. If you have a separate modem, restart that first, let it come fully online, then restart the router. A proper restart clears the router’s temporary faults and forces every device to reconnect fresh. Apple gives the same advice from the other side: if you manage the router, restart it and install the latest firmware updates its maker offers. Wait several minutes after the restart before judging it — routers take longer to settle than the lights suggest.

Check placement and interference

WiFi weakens through walls and floors, and it competes with other signals. A router shut in a cupboard, sitting on the floor, or placed behind a television starts at a disadvantage. Move it higher, out in the open, and as central in the home as the cable allows. Keep it away from thick masonry, large metal objects, and the microwave. If drops happen mainly in one far room, you have a coverage problem, not a fault: the honest fixes are moving the router, adding a mesh node or access point for that area, or using the 2.4 GHz band in that room — it reaches further than 5 GHz, at lower speed. The 5 GHz band is faster but shorter-ranged, so a device at the edge of 5 GHz coverage will drop and reconnect repeatedly as it hunts between bands; that hunting is a common cause of WiFi disconnecting randomly on a single device in a single room.

Check the router settings that cause repeat drops

If restarts help only briefly, compare your router’s settings with Apple’s recommended settings for Wi-Fi routers and access points. Apple publishes these for its own devices, but most of them are good practice for any network:

  • Security: WPA3 Personal, or WPA2/WPA3 Transitional if older devices need it. Apple warns that older modes — WPA, WEP, TKIP and mixed WPA/WPA2 — reduce security and reliability.
  • Channel: set to Auto, so the router picks the least crowded channel itself.
  • Channel width: 20 MHz on the 2.4 GHz band; Auto on 5 GHz and 6 GHz. Wider channels are faster but more open to interference.
  • One network name for all bands: give every band the same name, so devices move between bands without treating them as separate networks.
  • Firmware: set the router to install updates automatically if it offers that, or check the maker’s app or admin page for updates yourself.

Also check that only one device on your network is handing out addresses (DHCP) and doing NAT — a modem-router and a second router both doing it is a classic cause of connections that drop in a pattern nobody can explain. If your provider supplied the modem and you added your own router, put one of them in bridge mode, following the maker’s own instructions for your models.

Router admin pages differ completely between brands, so this article deliberately does not give click-by-click router paths: open your router maker’s own help for your model and find the same-named settings there.

When it is the provider’s fault

If every device drops, the router restart does not hold, and the modem’s own status lights show the line itself dropping, the fault is upstream and no home fix will cure it. Note the times of several drops, check the provider’s service status page, and report it with your times. Drop patterns that hit the whole street are the provider’s to fix; a single home dropping at random is usually local. “Internet keeps disconnecting” and “WiFi keeps disconnecting” are often used for the same complaint, but they separate here: if the modem loses its line, that is an internet fault; if the line stays up while devices lose the wireless link, that is a WiFi fault — and telling the provider which one you have shortens the call considerably.

Use network reset only as a last resort

Both Windows and phones offer a full network reset. On Windows it sits at Settings > Network & internet > Advanced network settings > Network reset, and Microsoft lists it as the last step in its own sequence, after the troubleshooter, forget-and-rejoin, and the driver steps. A reset removes saved networks and network settings and returns them to defaults — every saved WiFi password goes with it. It is the right tool when a device drops on every network and nothing above has worked, and the wrong tool as a first try. If one device drops on every network it joins — home, work, a friend’s house — while other devices hold those same networks, suspect that device’s hardware and contact its maker; software has been ruled out at that point.

Frequently asked questions

Why does my WiFi keep disconnecting on just one device? Because the fault is in that device: a saved network profile gone stale, an out-of-date driver or system, a VPN or security app interfering, or power settings that put its WiFi adapter to sleep. Forget and rejoin the network, restart, update, and only then consider the driver reinstall and network reset steps above. Other devices staying connected is what proves the router innocent.

Why does my WiFi keep disconnecting on my laptop but not my phone? Usually the laptop’s driver or power management, or band hunting: the laptop sits at the edge of the faster 5 GHz band’s range and keeps falling off it, while the phone — often closer to the router, or more willing to stay on 2.4 GHz — holds on. Test the laptop in the same room as the router. If it holds there, it is a coverage problem; if it drops there too, work through the driver and forget-and-rejoin steps.

Why does WiFi disconnect randomly with no pattern? Random-looking drops usually have a hard-to-see cause: interference from a neighbour’s network on the same channel, a device switching between bands, or a router fault that builds up until it is restarted. Channel on Auto, one name for all bands, and current firmware remove the most common three. If drops survive that and hit every device, log the times and take it to the provider.

Will a new router fix WiFi that keeps disconnecting? Only if the router is the fault — every device dropping, restarts helping briefly, firmware already current. If one device drops, a new router usually changes nothing. Do the one-device versus all-devices test first; it costs nothing and answers this directly.

Does resetting the router to factory settings help? It wipes your network name, password and every custom setting, and the fault often returns if the cause was placement, interference or the line. A restart — power off, wait, power on — is a different, harmless step and should always come first.
