If your PC keeps disconnecting from WiFi, it can be due to a variety of issues, ranging from network settings to hardware problems. Here are some troubleshooting steps to help you resolve the issue:
1. Check Your WiFi Connection
- Test Other Devices: Check if other devices (smartphones, tablets, etc.) are also experiencing WiFi disconnections. If they are, the issue might be with your router or internet service.
- Restart Your Router/Modem: Unplug your router/modem, wait for 30 seconds, then plug it back in. This can often resolve connectivity issues.
- Change WiFi Channel: If you're using a crowded WiFi channel, try switching to a less congested one. Many routers have an automatic channel selection option, or you can manually set it through the router's settings.
2. Update Network Drivers
- Update WiFi Driver: Outdated or corrupted WiFi drivers can cause disconnections. To update the driver:
- Go to Device Manager > Network Adapters.
- Right-click your WiFi adapter and select Update Driver.
- Choose Search automatically for updated driver software and follow the instructions.
- Reinstall WiFi Driver: If updating doesn't help, uninstall the driver and reboot your PC. Windows will reinstall the driver on startup.
3. Check Power Settings
- Disable Power Saving for WiFi Adapter:
- Open Device Manager > Network Adapters > Right-click your WiFi adapter > Properties.
- Under the Power Management tab, uncheck Allow the computer to turn off this device to save power.
- Adjust Power Settings: Go to Control Panel > Power Options, and make sure you're using a balanced or high-performance plan. Avoid using the Power Saver plan, as it can limit network performance.
4. Forget and Reconnect to the WiFi Network
- Go to Settings > Network & Internet > WiFi > Manage Known Networks.
- Select your WiFi network and click Forget.
- Reconnect to the network by selecting it from the list and entering your password again.
5. Change DNS Settings
Sometimes, your DNS (Domain Name System) settings can cause connection issues. You can try switching to a more reliable DNS service like Google's or OpenDNS:
- Open Network & Internet Settings > Change Adapter Settings.
- Right-click your WiFi adapter > Properties > Select Internet Protocol Version 4 (TCP/IPv4) > Use the following DNS server addresses.
- Set Preferred DNS server to 8.8.8.8 (Google DNS) and Alternate DNS server to 8.8.4.4.
6. Disable WiFi Sense (Windows 10/11)
- WiFi Sense is a feature in Windows that can automatically connect to open networks. Sometimes, it can cause instability in your WiFi connection.
- Go to Settings > Network & Internet > Wi-Fi > Manage Wi-Fi Settings.
- Turn off Connect to suggested open hotspots and Connect to networks shared by my contacts.
7. Check for Interference
- Physical Obstacles: Ensure there are no physical obstructions like walls or microwaves that could be interfering with your WiFi signal.
- Interference from Other Devices: Devices like cordless phones or baby monitors can cause interference on the same frequency bands (2.4GHz and 5GHz). Try moving your router to a different location or switching your router to a different frequency band.
8. Update Windows
- Make sure your operating system is up to date, as Windows updates often contain bug fixes and network improvements.
- Go to Settings > Update & Security > Windows Update and check for updates.
9. Run Windows Network Troubleshooter
- Open Settings > Network & Internet > Status > Network Troubleshooter.
- Follow the on-screen prompts to diagnose and potentially fix the issue.
10. Check for Malware or Viruses
- Malware or viruses can disrupt your internet connection. Run a full system scan using Windows Defender or a third-party antivirus program to ensure your PC is not infected.
11. Try a Different WiFi Adapter
If none of the above solutions work, the issue might be with your WiFi card. You can try using an external USB WiFi adapter to see if the problem persists.
