If your laptop wifi keeps disconnecting, the problem is usually a power setting, an outdated driver, or a weak signal — not a broken laptop. Work through the fixes below in order, starting with the easiest, and test your connection after each one. Most people find the cause within the first few steps.

Diagnose the Problem First
Before changing settings, spend two minutes narrowing down the cause. A laptop that drops its connection every few minutes behaves differently from one that loses WiFi only in a particular room, and the fix is different too. Note when the drops happen: during video calls, after the laptop wakes from sleep, or at random times through the day. That pattern is a useful clue.
When wifi drops every few minutes (commonly searched as wifi drops every few minutes laptop), the usual suspects are a power-saving setting that switches the adapter off, a driver that crashes under load, or a signal that is too weak to hold a steady connection. When windows 11 wifi disconnects randomly after an update, a driver change is more likely. Keeping a brief note of the timing helps you judge which fix actually worked.
| What you observe | What it probably means | Try first |
|---|---|---|
| Only your laptop drops; other devices stay connected | The fault is on the laptop — adapter, driver or power setting | Fixes 3, 4 and 5 |
| Other devices drop too, at the same time | The fault is with the router or your internet service (ISP) | Fix 1, then contact your ISP if it continues |
| Drops happen far from the router, but not nearby | Weak signal or interference | Fix 2 |
| Drops happen after sleep or when idle | Windows is turning the adapter off to save power | Fix 3 |
| WiFi stays connected but pages will not load | A laptop wifi connected but no internet problem — often DNS or a router fault | Fixes 1, 6 and 7 |
| Drops started after a Windows or driver update | A driver or update conflict | Fix 5 |
The single most useful test is the other-devices test. If your phone or another computer drops at the same moment, do not spend an hour reinstalling laptop drivers: restart the router, check whether your provider reports an outage, and contact your ISP if the drops continue. If only the laptop drops, the rest of this guide is for you.
Fix 1: Restart Your Router and Rejoin the Network
Start with the classic for a reason: it clears temporary faults in the router and forces a fresh connection. Unplug your router from power, wait 30 seconds, plug it back in, and wait until its lights show it is fully online again. Then restart your laptop as well, so both ends of the connection start clean.
Next, forget the network on your laptop and join it again. Go to Settings, then Network and internet, then WiFi, then Manage known networks. Select your network, choose Forget, then reconnect and type the password again. This clears a corrupted saved profile, which can cause repeated drops even when the password itself is correct.
Fix 2: Switch WiFi Bands and Reduce Interference
Most modern routers broadcast two bands: 2.4 GHz, which travels further through walls but is slower and more crowded, and 5 GHz, which is faster over short distances but weaker through walls. If your laptop is far from the router, 2.4 GHz may hold a steadier connection. If you are in the same room, 5 GHz is usually the better choice.
To switch bands, forget the network as in Fix 1, or look in your WiFi list for a separate network name for each band — many routers show them separately. Connect to the other band and test for an hour. Also try moving closer to the router, or moving the router away from thick walls, large metal objects, microwaves and cordless phone bases, all of which can interfere with the signal.
Interference is also a neighbour problem. In flats and busy buildings, many routers compete on the same channels. If your router lets you choose a channel, or has an automatic channel setting, make sure that automatic selection is switched on. A crowded channel can look exactly like a faulty adapter: the connection drops, recovers, then drops again.
Fix 3: Stop Windows Turning Off Your WiFi Adapter
This is the most common cause of drops after sleep or idle time, and it is also the most overlooked. Windows can switch off the WiFi adapter to save power, and some adapters do not wake up cleanly. The wifi adapter power saving fix below stops that behaviour.
Open Device Manager, expand Network adapters, right-click your WiFi adapter, and choose Properties. Go to the Power Management tab and untick “Allow the computer to turn off this device to save power”. Click OK, then restart your laptop.
Next, check your power plan. Go to Settings, then System, then Power and battery, and set the power mode to Best performance while you test. On laptops with a full Control Panel power-plan view, choose the High performance or Maximum Performance plan if one is offered. A laptop set to aggressive power saving is more likely to throttle or switch off its wireless adapter, especially on battery power.
Fix 4: Run the Network Troubleshooter and Read the WLAN Report
Windows includes a network troubleshooter that can reset the adapter and apply common repairs automatically. Go to Settings, then System, then Troubleshoot, then Other troubleshooters, and run the Network and Internet troubleshooter. Apply any fix it suggests, then test again. It will not solve every problem, but it is quick and it sometimes catches a misconfigured adapter.
The step most competing guides skip is the WLAN report, and it is worth doing. It records exactly when your laptop connected, disconnected and roamed between access points, which helps you find the drop cause instead of guessing. Open Command Prompt or Windows Terminal as an administrator and run:
netsh wlan show wlanreport
Windows saves the report as an HTML file and shows you its location, usually in a system folder. Open it in your browser and look at the summary and the session entries: repeated disconnect events, failed roaming attempts, or driver-related errors point you towards the right fix. For example, drops that line up with roaming between access points suggest Fix 7, while driver errors point to Fix 5.
You can also check community discussion of similar symptoms while you interpret the report. Other Windows 11 users describe the same random-drop pattern in detail in threads such as this Microsoft Answers discussion and this Microsoft Tech Community discussion, which can help you compare your symptoms with theirs.
Fix 5: Update or Reinstall Your WiFi Driver
Drivers are the software that lets Windows talk to the WiFi adapter, and a buggy or outdated driver is a leading cause of random disconnects. Start with Windows Update: go to Settings, then Windows Update, and install any pending updates, including optional driver updates listed under Advanced options.
For the most reliable result, get the driver from your laptop manufacturer’s support site, not from a generic driver-download tool. Search for your exact laptop model, download the latest wireless driver for Windows 11, and install it. Manufacturer drivers are tested against your model, while generic tools can install the wrong version.
If updating does not help, reinstall the driver cleanly. In Device Manager, right-click the WiFi adapter and choose Uninstall device. If you are offered the option to delete the driver software, tick it. Restart the laptop, and Windows will reinstall a driver automatically; then install the manufacturer’s version on top if needed. If you have no internet at all after uninstalling, use another device to download the driver and transfer it on a USB drive.
Fix 6: Reset the Network Stack
If the adapter and driver look healthy but the connection still drops, corrupted network settings may be to blame. Resetting the network stack clears those settings without touching your files. Open Command Prompt or Windows Terminal as an administrator and run these commands one at a time, restarting afterwards:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
The first command resets the Windows networking catalogue, the second resets the internet protocol settings, and the third clears the DNS cache. Together they remove stale or damaged entries that can interrupt a connection that otherwise looks fine.
Fix 7: Change Wireless Mode, Roaming Aggressiveness and DNS
This is the second step most guides skip, and it matters when the WLAN report shows roaming problems or when a newer wireless standard is unstable on your adapter. In Device Manager, open your WiFi adapter’s Properties and go to the Advanced tab. The exact options depend on your adapter, but look for these settings.
First, wireless mode. If it is set to a mode that includes 802.11ax (WiFi 6), try changing it to a mode that tops out at 802.11ac (WiFi 5), such as “802.11a/b/g/n/ac”. Some older adapters and routers handle the newer standard poorly, and stepping down to AC can turn an unstable connection into a steady one, at the cost of some top speed. Test for a day before judging the change.
Second, roaming aggressiveness. This controls how eagerly the laptop jumps between access points or bands. If your report shows frequent roaming, set roaming aggressiveness to its lowest setting. The laptop will then stay on its current connection longer instead of hopping to a marginally stronger signal and dropping in the process.
Third, DNS. If pages load slowly or fail even while WiFi shows as connected, try a public DNS service. In your adapter’s internet protocol settings, you can set a preferred DNS server manually. Write down your original settings first, and revert if the change makes no difference. A DNS change will not fix a signal problem, but it can fix a laptop wifi connected but no internet symptom where the connection itself is fine.
Fix 8: Full Network Reset as a Last Resort
If nothing above has worked, use Windows’ built-in network reset. Go to Settings, then Network and internet, then Advanced network settings, then Network reset, and choose Reset now. This removes and reinstalls all network adapters and returns networking settings to their defaults.
When to See a Repair Shop or Contact Your ISP
See a repair shop if the laptop drops WiFi on every network, including a phone hotspot, after you have tried Fixes 3 to 8. That pattern points to the laptop’s own hardware. Also seek repair if the WiFi adapter disappears from Device Manager, if Bluetooth fails at the same time on a combined card, or if the laptop has suffered a drop or liquid spill. Tell the shop which fixes you have already tried; it saves diagnostic time and cost.
Contact your ISP if other devices drop at the same time, if the router’s internet light goes out during drops, or if the problem continues after a router restart and a replacement router test. Before calling, note the times of recent drops and whether they affect wired devices too. A wired device that also drops proves the problem is upstream of WiFi entirely, which is exactly the evidence an ISP support team needs.

If your laptop’s built-in adapter is the problem, a USB WiFi adapter can be a useful workaround: it plugs into a USB port and gives the laptop a second wireless adapter, which can also add support for a newer WiFi standard. Check that the adapter supports your router’s band and Windows 11 before buying, and buy from a seller with a clear returns policy in case it does not suit your laptop.
If the problem is range rather than the laptop, a WiFi extender placed halfway between the router and the room where you work can strengthen the signal. Extenders work best when they still receive a decent signal themselves, so place one where your phone still shows a solid connection, not in the dead spot itself.

Frequently Asked Questions
Why does my laptop keep disconnecting from WiFi?
The most common causes are a power-saving setting that switches the adapter off, an outdated or faulty WiFi driver, a weak or crowded signal, or a router fault. If only your laptop drops, start with the power setting and the driver. If other devices drop too, the router or your internet service is the likelier cause.
How do I stop my WiFi from dropping on Windows 11?
Turn off the adapter’s power-saving option in Device Manager, keep your WiFi driver updated from your laptop manufacturer’s site, and stay on the band that gives the steadiest signal in your room. If drops continue, run the WLAN report with netsh wlan show wlanreport to find the cause, then reset the network stack or adjust roaming aggressiveness as described above.
Can a driver cause WiFi to disconnect?
Yes. A buggy, outdated or mismatched driver can crash the adapter, fail to recover after sleep, or mishandle newer wireless standards. Updating to the latest manufacturer driver for Windows 11, or cleanly reinstalling it, resolves many random disconnects. If a driver update coincides with the start of the problem, rolling back or reinstalling that driver is a sensible first step.
Does power saving mode turn off WiFi?
Yes, it can. Windows may switch off the WiFi adapter to save power, particularly on battery power or after sleep, and some adapters do not reconnect cleanly. Untick “Allow the computer to turn off this device to save power” in the adapter’s Power Management settings and use a higher-performance power plan while testing, to rule this cause out.
