How to Fix Wi-Fi That Keeps Disconnecting

Step by step

1. Check signal strength and proximity to router

   Move within 30 feet of your router and check if disconnections stop. Walls, floors, and electronic devices weaken Wi-Fi signals. If connectivity improves with proximity, your device is operating at the edge of your network's range.

   Note: Use Wi-Fi analyzer apps to see signal strength in dBm. Anything weaker than -70 dBm will cause connection issues.

2. Restart your router and modem

   Unplug your router and modem from power for 30 seconds. Plug in the modem first and wait 2 minutes for full startup. Then plug in the router and wait another 2 minutes. This clears temporary glitches and refreshes your network connection.

   Note: Schedule automatic router reboots weekly through your admin panel to prevent connection degradation.

3. Update your device's network drivers

   Open Device Manager on Windows (Windows key + X, then M) and expand Network adapters. Right-click your Wi-Fi adapter and select Update driver. On Mac, go to Apple menu > About This Mac > Software Update. On mobile devices, check for system updates in Settings.

   Note: Download drivers directly from your Wi-Fi adapter manufacturer's website for the latest version, not generic Windows drivers.

4. Reset network settings on your device

   On Windows, open Command Prompt as administrator and run 'netsh winsock reset' then 'netsh int ip reset'. On Mac, go to System Preferences > Network, select Wi-Fi, click Advanced, then Remove to delete the network and re-add it. On iOS, go to Settings > General > Reset > Reset Network Settings.

   Note: Back up saved Wi-Fi passwords before resetting network settings as you'll need to re-enter them.

5. Switch to a less congested Wi-Fi channel

   Access your router's admin panel by typing 192.168.1.1 or 192.168.0.1 in your browser. Navigate to Wireless Settings and change the channel to 1, 6, or 11 for 2.4GHz networks. For 5GHz networks, try channels 36, 44, 149, or 157. Save settings and restart the router.

   Note: Use Wi-Fi analyzer tools to identify which channels have the least interference from neighboring networks.

6. Disable power management for your Wi-Fi adapter

   In Windows Device Manager, right-click your Wi-Fi adapter and select Properties. Go to Power Management tab and uncheck 'Allow the computer to turn off this device to save power'. On Mac, go to System Preferences > Energy Saver and adjust settings to prevent Wi-Fi from sleeping.

   Note: This fix is crucial for laptops that aggressively manage power consumption and may shut down Wi-Fi to conserve battery.

7. Update router firmware

   Log into your router's admin interface and check the firmware version against the latest available on the manufacturer's website. Download and install updates if available. Most modern routers have automatic update options in the administration settings that you can enable.

   Note: Set up automatic firmware updates if available to prevent security vulnerabilities and connection issues from outdated software.
