Laptop Keeps Disconnecting From Wi-Fi? 10 Fixes

If your laptop keeps disconnecting from Wi-Fi, first work out whether the problem follows the laptop or the network. If every device drops out, focus on the router or ISP. If only one laptop disconnects, the likely causes are the saved Wi-Fi profile, adapter driver, power management, band compatibility or a software/network setting on that laptop.

On a Windows 11 laptop, the safest order is: reconnect to the network, restart the router, run Windows’ network troubleshooter, update the Wi-Fi driver, check power-saving settings, then use Network Reset only as a last resort. On a Mac, start with Wi-Fi Recommendations or Wireless Diagnostics.

Symptom	Most useful first test
Every device loses Wi-Fi	Restart router/modem and check ISP status
Only one laptop disconnects	Forget/rejoin network and update adapter driver
Drops happen far from router	Test closer to router or on another Wi-Fi band
Disconnects after sleep	Check Wi-Fi adapter power-saving settings
Wi-Fi connects but internet disappears	Test another device; then reset IP/DNS if needed

1. Check whether the laptop or the Wi-Fi network is the problem

Before changing settings, test another phone or computer on the same Wi-Fi network.

• If several devices disconnect: the router, modem, ISP connection or local interference is the more likely cause.
• If only your laptop disconnects: troubleshoot the laptop’s Wi-Fi profile, driver and adapter settings.

Microsoft and Apple both recommend this kind of isolation test because it quickly tells you whether to work on the device or the network.

2. Forget the Wi-Fi network and reconnect

A saved Wi-Fi profile can become unreliable after router, password or security-setting changes.

Windows 11

1. Open Settings > Network & internet > Wi-Fi.
2. Select Manage known networks.
3. Select your Wi-Fi network and choose Forget.
4. Reconnect and enter the password again.

Mac

1. Open System Settings > Wi-Fi.
2. Scroll to Advanced.
3. Open the menu beside the network and choose Remove From List.
4. Reconnect normally.

Microsoft’s current Windows Wi-Fi troubleshooting guide and Apple’s current forget-network instructions both include this step.

3. Restart the modem and router

A router can develop a stale connection, DHCP problem or temporary radio issue. Restarting it is still one of the most useful basic tests.

1. Unplug the modem and router.
2. Wait roughly 30 seconds.
3. Reconnect the modem first and let it come fully online.
4. Reconnect the router and wait for Wi-Fi to return.
5. Test the laptop again.

If every device in the house was dropping out and the problem returns quickly after a restart, check the router’s firmware, cabling and ISP status rather than endlessly changing laptop settings.

4. Run the current Windows 11 network troubleshooter

The old version of this guide told readers to right-click the taskbar Wi-Fi icon and use the old Windows troubleshooter. In current Windows 11, Microsoft directs users to the automated Network and Internet troubleshooter in the Get Help app.

Use Windows Search for Get Help, then run the network troubleshooting flow. It can diagnose common adapter and configuration problems automatically.

5. Update or reinstall the Wi-Fi adapter driver

If the disconnects began after an update, wake-from-sleep problem or driver crash, the Wi-Fi adapter driver may be responsible.

Start by checking:

• Windows Update for driver updates;
• your laptop manufacturer’s support page; and
• the Wi-Fi adapter manufacturer’s current driver, where appropriate.

If ordinary updating does not help, Microsoft recommends uninstalling the network adapter in Device Manager and restarting the PC so Windows can reinstall it. Download a backup driver first if the laptop has no other way to get online.

6. Check Wi-Fi power-saving settings

A laptop that disconnects after sleeping, waking or running on battery may be allowing Windows to power down the wireless adapter.

1. Open Device Manager.
2. Expand Network adapters.
3. Open your Wi-Fi adapter’s Properties.
4. If a Power Management tab is available, clear Allow the computer to turn off this device to save power.

Microsoft specifically recommends this for frequently dropping Wi-Fi connections.

7. Try another Wi-Fi band

Modern routers may broadcast on 2.4GHz, 5GHz and, on Wi-Fi 6E/7 equipment, 6GHz.

• 2.4GHz usually travels farther but is more crowded.
• 5GHz generally offers more bandwidth at shorter range.
• 6GHz can provide very clean spectrum but requires compatible hardware and has shorter practical range through obstacles.

If your router exposes separate network names for each band, test another one. Microsoft explicitly recommends switching between 2.4GHz and 5GHz when diagnosing connection problems.

If you are deciding between wireless and a cable for gaming, our Wi-Fi 7 vs Ethernet gaming guide explains the trade-offs.

8. Reduce interference and improve signal

Walls, metal, distance and nearby 2.4GHz devices can all reduce Wi-Fi reliability. Microwaves, cordless equipment and Bluetooth can contribute to interference in the 2.4GHz band, although modern Wi-Fi and Bluetooth are designed to coexist far better than the old article implied.

Useful tests include:

• move closer to the router;
• move the router into a more open, central position;
• test 5GHz if 2.4GHz is crowded;
• avoid placing the router behind a TV, metal cabinet or large appliance; and
• temporarily turn off nearby sources of interference to see whether the problem changes.

Apple’s current support documentation also lists wireless interference as a cause of disconnects and poor Wi-Fi performance.

9. If Wi-Fi stays connected but the internet disappears, reset the network stack

On Windows, Microsoft recommends these commands when ordinary troubleshooting does not resolve the connection:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Run Command Prompt as administrator, enter them in order, then restart the PC.

This is most useful when the laptop still appears connected to the router but internet access or DNS resolution keeps failing.

10. Use Network Reset only after the simpler fixes

Windows Network Reset removes installed network adapters and returns their settings to defaults, so it is deliberately a last-step fix.

On Windows 11:

1. Open Settings > Network & internet.
2. Choose Advanced network settings.
3. Select Network reset.
4. Choose Reset now.

You may need to reinstall VPN software, virtual adapters or other networking tools afterward.

What not to do

The previous version of this article included several pieces of advice that should not be followed:

• Do not buy a second router just because the network is busy. A second router does not create more ISP bandwidth and can create additional interference if configured badly.
• Do not uninstall antivirus software as a routine Wi-Fi fix. If a VPN, firewall or security product is genuinely suspected, troubleshoot that specific product and keep the device protected.
• Do not randomly change router channels without understanding your router. Modern routers often choose channels automatically; manual changes are useful only when interference is actually the problem.

MacBook keeps disconnecting from Wi-Fi

On macOS, Apple recommends checking Wi-Fi Recommendations or running Wireless Diagnostics first. You can also forget and rejoin the network, restart the router and test whether other devices have the same problem.

Apple’s current Mac internet troubleshooting guide covers the built-in diagnostic tools.

When should you replace the router or Wi-Fi adapter?

Consider hardware replacement when:

• the router drops multiple devices even after firmware updates and resets;
• the laptop’s Wi-Fi adapter disappears from Device Manager or repeatedly fails despite current drivers;
• an external USB Wi-Fi adapter works reliably while the internal adapter does not; or
• your router is old enough that it lacks the security and Wi-Fi standards your current devices need.

Quick answer

If only your laptop keeps disconnecting, forget and rejoin the network, run the current OS troubleshooter, update the Wi-Fi driver and check adapter power-saving settings. If every device disconnects, focus on the router, modem, interference or ISP instead.
