Using a browser straight up kills all connection on my pc

Troubleshooting Network Disconnects Caused by Browser Usage: A Comprehensive Guide

Introduction

Many users experience perplexing network connectivity issues that occur exclusively when launching web browsers such as Chrome, Firefox, or Edge. These disruptions can significantly impair productivity and online experience. This article explores common causes and effective solutions for resolving browser-related internet disconnects, based on real-world user experiences and best practices.

Understanding the Issue

Users with high-performance systems—such as those with 32GB RAM, Ryzen 7 9800X3D processors, and dedicated GPUs like RX 9070 XT—may find that their internet connection remains stable during typical operations but repeatedly drops when opening browsers. Symptoms include:

Complete disconnection of all internet activities on the PC shortly after launching a browser.
Loss of access to applications like Discord, sometimes lasting for extended periods (10-30 minutes).
The network stabilizing temporarily but then disconnecting again.

Common User Actions and Observations

Operating on a wired Ethernet connection, with stable performance during other tasks.
Running VPNs explicitly, yet experiencing persistent disconnects regardless.
Initial suspicion of antivirus or VPN interference, with attempts to disable such features.
Testing different network configurations (Wi-Fi alongside Ethernet), with inconsistent results.
Multiple browser trials (Chrome, Edge, Firefox), all yielding similar disconnection issues.
Basic troubleshooting steps like restarting the PC and rechecking wiring, with little improvement.
Monitoring bandwidth and data usage, which appear normal during these events.

Potential Causes

Several factors can contribute to browser-induced network disconnects:

Network Driver Issues: Outdated or corrupted network adapters can cause intermittent connectivity problems.
Firewall or Security Software Conflicts: Overly strict firewall rules may block browser traffic or cause network stalls.
VPN Interference: VPN configurations may conflict with local network settings, leading to disconnections.
Browser Extensions or Settings: Corrupt or incompatible extensions, or specific browser settings, might trigger network issues.
Hardware or Driver Conflicts: Less common, but potential conflicts with hardware components or drivers can impact network stability.
TCP/IP Stack or Network Configuration Problems: Misconfigured network settings can cause delays or disconnections when browsers initiate connections.
