Fix Slow Network Speed
Learn how to identify what’s causing slow Wi-Fi or wired speeds and how to improve your overall network performance through step-by-step troubleshooting.
Tip: Always test your speed using both Wi-Fi and a direct Ethernet connection.
This helps determine whether the slowdown is caused by your router, cabling, or your internet provider.
Common Causes
- Too many devices sharing the same network bandwidth.
- Weak Wi-Fi signal or interference from nearby networks or microwaves.
- Outdated router firmware or network adapter drivers.
- Background updates or cloud sync consuming bandwidth.
- High latency from distant or overloaded servers.
Troubleshooting Steps
- Run a speed test at speedtest.net to get a baseline.
- Connect directly via Ethernet to rule out Wi-Fi issues.
- Reboot your router and modem to clear temporary congestion.
- Update your router’s firmware and your computer’s network drivers.
- Move your router to a central, elevated location for better coverage.
- Limit bandwidth-heavy apps like OneDrive sync, cloud backups, or streaming services.
Warning: Avoid performing router resets during software updates or downloads.
It may interrupt installations and cause data corruption. Always restart your network hardware safely.
Success Tip: After completing these steps, retest your connection and compare
results. If your speed remains significantly lower than your plan, contact your ISP for diagnostics.
