Troubleshooting Slow Download Speeds After Reinstalling Windows 11

Experiencing sluggish download speeds following a Windows 11 reinstallation can be frustrating, especially when your internet connection previously provided robust performance. If you’ve noticed your download speeds plummeting to around 1,000 KB/s and rarely exceeding 2.5 MB/s, despite a faster connection, there are several potential causes and effective solutions worth exploring.

Understanding the Issue

A clean Windows installation can sometimes reset or alter network settings, drivers, or system configurations, leading to reduced internet performance. Common factors contributing to slow download speeds include outdated or incompatible network drivers, misconfigured network settings, background processes, or Windows updates that need attention.

Step-by-Step Troubleshooting Guide

1. Verify Internet Speed Outside the Browser

2. Use tools like Speedtest.net to check your current connection speed directly. This helps determine if the issue is with your system or your ISP.
