How to Fix WiFi Keeps Disconnecting on Windows 10

If your WiFi keeps disconnecting on Windows 10, you’re not alone. This issue can disrupt everything — from online meetings to streaming Netflix or downloading large files. Whether you’re using a laptop or desktop PC, frequent WiFi dropouts are incredibly frustrating.

The good news? You can fix most of these problems quickly with a few adjustments.

In this comprehensive guide, we’ll explain why your WiFi disconnects randomly and provide practical fixes to help you stay connected.

Common Causes of WiFi Disconnecting in Windows 10

Understanding the root cause is the first step. Here are some of the most common reasons:

  • Power-saving settings turning off the WiFi adapter
  • Outdated or corrupt network drivers
  • Router incompatibility or signal interference
  • Incorrect IP configuration
  • Windows updates affecting network settings

Let’s walk through the most effective fixes step-by-step.

Fix 1: Disable WiFi Power Saving Mode

Windows tries to conserve battery by turning off hardware, including the WiFi adapter.

Steps:

  1. Press Win + X → Select Device Manager
  2. Expand Network Adapters
  3. Right-click your WiFi adapter → Properties
  4. Go to the Power Management tab
  5. Uncheck Allow the computer to turn off this device to save power
  6. Click OK and restart your PC

Fix 2: Update or Reinstall WiFi Drivers

Outdated drivers are a major reason behind WiFi instability.

Steps to update:

  1. Press Win + X → Choose Device Manager
  2. Expand Network Adapters
  3. Right-click your WiFi adapter → Update driver
  4. Choose Search automatically for updated driver software

If the issue persists, try uninstalling and reinstalling the driver:

  1. Right-click your WiFi adapter → Uninstall device
  2. Restart your PC. Windows will reinstall the driver automatically.

Fix 3: Change Network Adapter Settings

Tweaking adapter properties can sometimes stabilize your connection.

  1. Open Device Manager
  2. Right-click your WiFi adapter → Properties
  3. Go to the Advanced tab
  4. Change the Roaming Aggressiveness to Lowest
  5. Set Preferred Band to 5GHz (if your router supports it)

This reduces automatic switching between weak/strong networks, which can cause disconnection.

Fix 4: Reset TCP/IP and Flush DNS

Misconfigured IP settings can trigger disconnection issues. Use Command Prompt to reset.

Steps:

  1. Press Win + S, type cmd, right-click → Run as Administrator
  2. Run these commands one by one:
pgsqlCopyEditnetsh int ip reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
  1. Restart your computer

Fix 5: Forget and Reconnect to the Network

This resets all WiFi-related settings for the current network.

Steps:

  1. Go to Settings → Network & Internet → WiFi
  2. Click on Manage known networks
  3. Select your network → Click Forget
  4. Reconnect using the correct password

Fix 6: Disable Random Hardware MAC Address

MAC address randomization can sometimes lead to unstable connections.

Steps:

  1. Go to Settings → Network & Internet → WiFi
  2. Click your connected network
  3. Set Random hardware addresses to Off

Fix 7: Roll Back Recent Windows Updates

Some updates may conflict with your network drivers or settings.

Steps:

  1. Go to Settings → Update & Security → Windows Update
  2. Click on View update history
  3. Choose Uninstall updates
  4. Remove recent network-related updates (if any)

Fix 8: Temporarily Disable Antivirus or VPN

Overprotective antivirus or VPN services can interfere with WiFi connections.

  • Try disabling them temporarily
  • If the connection stabilizes, consider switching to a different antivirus or VPN

Fix 9: Check Router Settings and Placement

Sometimes, the issue isn’t Windows but the router itself:

  • Place router in a central location
  • Change WiFi channel to avoid interference
  • Restart your router regularly
  • Update router firmware if needed

Bonus Tips for Stable WiFi on Windows 10

  • Keep your Windows 10 system updated
  • Avoid using USB 3.0 ports for WiFi adapters (can cause interference)
  • Use Ethernet for ultra-stable connections, especially when streaming

Final Thoughts

If your WiFi keeps disconnecting on Windows 10, these methods should help restore a stable connection. Start with the simple fixes and move to advanced troubleshooting if needed. Don’t forget to regularly update your network drivers and check router performance.
