Troubleshooting Wi-Fi Connectivity Issues with ASUS TUF Gaming A15: Intermittent Signal Despite Active Connection

Introduction

Encountering inconsistent Wi-Fi connectivity can be a frustrating experience, especially when your device shows a connected status but fails to access the internet reliably. If you own an ASUS TUF Gaming A15 and have recently noticed that your Wi-Fi connection appears active but intermittently loses internet access, this article aims to provide a comprehensive overview of potential causes and professional troubleshooting steps.

Understanding the Issue

Many users report symptoms such as:

• The Wi-Fi connection being active but the internet is inaccessible.
• Frequent switching between 5GHz and 2.4GHz bands on the router.
• Browser errors like “ERR_NAME_NOT_RESOLVED” and “ERR_CONNECTION_TIMED_OUT.”
• The need to manually alternate between Wi-Fi networks to restore functionality.

These phenomena suggest that while the wireless network hardware maintains a link with your device, underlying issues may be affecting the actual data transmission or DNS resolution.

Common Causes

Several factors can contribute to such connectivity problems:

• Network configuration inconsistencies
• Driver or firmware conflicts
• Router or modem issues
• DNS resolution errors
• Interference or signal instability

However, since other devices on the same network operate smoothly, the problem may be specific to your laptop or its configuration.

Recommended Troubleshooting Steps

1. Verify Network Settings
