Handling WiFi Connectivity Issues on Your Newly Built PC: Troubleshooting Guide

Building a new custom PC can be an exciting experience, but it also brings its share of technical challenges. Recently, one enthusiast faced connectivity problems after assembling a high-performance system featuring an NVIDIA RTX 4070 Super, AMD Ryzen 7 7800X3D CPU, and an MSI B650 motherboard. Initially functioning flawlessly, the system suddenly began experiencing intermittent WiFi issues, disrupting productivity and causing considerable frustration.

In this article, we’ll explore common causes of WiFi connectivity problems on new custom-built PCs and provide practical troubleshooting steps to get your system back online efficiently.

Understanding the Issue

The user reports that upon startup, the PC connects to WiFi briefly—approximately five minutes—before losing internet access despite remaining connected to the network. Repeated restarts temporarily restore connectivity, but the issue persists. The problem has significantly impacted workflow, leading to hours of downtime.

Common causes for such issues include:

Driver conflicts or outdated network drivers
Incorrect or misconfigured network settings
Hardware compatibility issues
Router or modem incompatibilities
Interference or signal issues

Troubleshooting Steps

Update and Reinstall Network Drivers
Identify your network device: In Device Manager (Windows), locate your WiFi adapter under “Network Adapters.”
Update driver software: Right-click and select “Update Driver,” opting for the latest version from the manufacturer’s website if necessary.
Reinstall drivers: Uninstall the current driver, then restart your PC and install the latest driver cleanly.
Reset Network Settings
Use Windows Network Reset feature:
- Navigate to Settings > Network & Internet > Status.
- Click on “Network reset” and follow prompts to reset all network adapters to default settings.
After reset, restart your PC and reconnect to WiFi.
Check Power Management Settings
In Device Manager, right-click your WiFi adapter and select Properties.
Go to the Power Management tab.
Uncheck “Allow the computer to turn off this device to save power.”
Configure Router Settings
Ensure your router firmware is up to date.
Change WiFi channel, if necessary, to reduce interference.
Disable any security features temporarily to test connectivity.
Test with a Wired Connection or Different Network
