Title: Troubleshooting Unreliable Wi-Fi Connectivity on Your PC: A Step-by-Step Guide
Are you experiencing inconsistent Wi-Fi connectivity issues on your Windows PC, where your device randomly disconnects or cannot access the internet despite other devices functioning normally? You’re not alone, and fortunately, there are several effective troubleshooting steps you can take to resolve these problems. This article outlines common causes and solutions for Wi-Fi connection issues, including error messages like “Can’t reach DNS server” and “No internet, secured.”
Understanding the Issue
Many users face intermittent Wi-Fi connectivity that manifests as:
- Inability to connect to Wi-Fi at startup or after periods of disconnection.
- Recurring error messages such as “Can’t reach DNS server” or “No internet, secured.”
- Fluctuating connection stability, with some moments working flawlessly and others failing to connect.
It’s important to note that if other devices like smartphones or tablets connect without issues, the problem likely resides with the PC, not the network itself.
Common Causes
- Corrupted network configuration or DNS cache.
- Outdated or faulty network adapter drivers.
- Power management settings turning off network adapters to save energy.
- Hardware issues like a faulty Wi-Fi antenna.
- Software conflicts or misconfigurations.
Step-by-Step Troubleshooting
