Your laptop connects to Wi-Fi, works for ten minutes, then drops. You reconnect, it’s fine for a while, then it happens again in the middle of a video call. Your phone on the same network has no trouble at all, which makes the whole thing even more frustrating.
When a laptop keeps disconnecting from Wi-Fi, the cause is usually on the laptop itself: power-saving settings, an outdated driver or a confused network profile. I’ve listed the fixes below in the order I try them. If your laptop connects but shows “no internet”, that’s a different problem, covered in our guide to Wi-Fi connected but no internet.

1. Confirm It’s the Laptop, Not the Router
Before changing anything, check whether other devices drop at the same time. If phones and TVs also lose connection, restart the router and check for an outage with your provider. If only the laptop drops, carry on below.

2. Stop Windows Turning Off the Wi-Fi Adapter
This is the most common cause. To save battery, Windows can switch off the wireless adapter when it thinks it’s idle, and it doesn’t always wake up cleanly.
- Right-click Start and open Device Manager.
- Expand Network adapters and double-click your Wi-Fi adapter (it usually has “Wireless” or “Wi-Fi” in the name).
- Open the Power Management tab.
- Untick Allow the computer to turn off this device to save power.
Also check Settings > System > Power & battery. If energy saver is set to turn on automatically at a high battery level, it can make wireless behaviour more aggressive.
3. Update or Roll Back the Wi-Fi Driver
Drivers are the next suspect, especially if the problem started after an update. Download the latest wireless driver from your laptop manufacturer’s support page, or from the chip maker (Intel, Realtek, MediaTek or Qualcomm) if your manufacturer’s version is old.
If the problem started right after a driver update, roll it back instead: in Device Manager, open the adapter’s properties, go to the Driver tab and choose Roll Back Driver.
4. Forget the Network and Reconnect
A corrupted saved profile can cause repeated drops, especially if you changed the router’s password or security type at some point and Windows is still holding old settings. Go to Settings > Network & internet > Wi-Fi > Manage known networks, select your network and click Forget. Reconnect and enter the password again.
5. Switch Bands or Pick a Better Channel
Most routers broadcast on 2.4GHz and 5GHz, and newer ones on 6GHz too. If the router combines them under one name, your laptop may keep jumping between bands as signal changes, dropping briefly each time.
- Close to the router: 5GHz is faster and usually more stable.
- Far from the router or through thick walls: 2.4GHz reaches further.
In your router settings, you can give each band its own name and connect the laptop to the one that suits where you sit. If neighbours’ networks crowd the same channel, changing the router’s channel can also help.
6. Disable Random Hardware Addresses (for Some Routers)
Windows can use a random hardware (MAC) address for privacy. Some routers with strict access control or older firmware handle this badly. In Settings > Network & internet > Wi-Fi, open your network’s properties and set Random hardware addresses to Off for your home network, then reconnect.
7. Change the Adapter’s Roaming Settings
In Device Manager, open the Wi-Fi adapter’s properties and look at the Advanced tab. Options vary by chipset, but two are worth checking:
- Roaming aggressiveness: set it to Lowest or Medium-low if you’re using one router, so the laptop stops hunting for a “better” access point.
- Preferred band: set it to prefer 5GHz if you’re close to the router.
8. Run the Network Troubleshooter and Reset the Stack
Windows 11’s built-in troubleshooter can find obvious problems: Settings > System > Troubleshoot > Other troubleshooters > Network and Internet.
If that finds nothing, open Terminal as administrator and run these commands, then restart:
netsh winsock reset netsh int ip reset ipconfig /flushdns
Microsoft’s Windows support site documents these steps along with known issues for recent updates.
9. Use Network Reset as a Last Software Step
Settings > Network & internet > Advanced network settings > Network reset removes and reinstalls all network adapters and returns settings to default. You’ll need to reconnect to Wi-Fi and reconfigure any VPN software, so save it for when other fixes fail.
10. Consider a Failing Adapter or Loose Antenna
If the laptop drops Wi-Fi on every network, even after a network reset and fresh drivers, the hardware may be the problem. Warning signs include very weak signal compared with other devices, drops when you move the screen, or the adapter disappearing from Device Manager.
A cheap USB Wi-Fi adapter is a quick way to test: if it stays connected, the internal card or antenna is at fault. Many laptops use replaceable M.2 Wi-Fi cards, so a repair shop can often swap it inexpensively.
Quick Checklist
| Symptom | Try first |
|---|---|
| Drops after idle or on battery | Power management setting |
| Started after Windows update | Roll back or update the driver |
| Drops when moving around the house | Separate bands, lower roaming |
| Only one network affected | Forget network, check router |
| Every network affected | Network reset, test USB adapter |
Habits That Keep the Connection Stable
After you’ve fixed the drops, a few simple habits help keep the connection reliable:
- Restart the router occasionally. Consumer routers benefit from a reboot every few weeks, and many let you schedule one overnight.
- Update router firmware. Firmware updates fix stability bugs and security holes. Check the router’s admin page or app.
- Place the router well. Central, raised and away from microwaves, fish tanks and thick walls gives a stronger signal throughout the home.
- Consider mesh Wi-Fi for large homes. If drops happen only in certain rooms, a mesh system often solves it better than any laptop setting.
- Keep Windows and drivers current. Let optional driver updates install through Windows Update or your manufacturer’s support app.
If you rely on the laptop for video calls, an inexpensive USB-C Ethernet adapter is also worth keeping in your bag. A wired connection removes Wi-Fi from the equation entirely when stability matters most.
Frequently Asked Questions
Why does my laptop disconnect from Wi-Fi but my phone doesn’t?
Laptops use different adapters, drivers and power-saving rules. Power management and driver issues are the usual causes.
Can a VPN cause Wi-Fi drops?
A VPN can make the connection appear to drop if it reconnects or blocks traffic. Disable it temporarily to test.
Will a network reset delete my files?
No. It only resets network adapters and settings.
Key Takeaways
- Most drops are caused by power saving, drivers or band switching.
The Bottom Line
Most Wi-Fi drops on Windows 11 laptops come from power-saving settings, drivers, band switching or a corrupted profile. Work through these ten fixes in order and the connection usually stabilises. If nothing helps, test with a USB adapter to confirm a hardware fault before paying for repair. For more fixes, browse our Laptops & PCs section or read how to speed up a slow Windows 11 laptop.
