How to Fix Slow Internet After Extender Setup

For many users on MyWi-Fiext.net, the excitement of extending Wi-Fi coverage quickly turns into frustration when the internet speed drops after installing an extender. This blog explains why speeds can decrease and how to fix it.

Why Speeds Slow After Extending Wi-Fi

• Poor extender placement
• Channel interference
• Incorrect frequency band usage
• Bandwidth hogging devices
• Outdated modem/router firmware

Troubleshooting Slow Speeds

1. Choose the Right Frequency Band

Modern networks offer:

• 2.4 GHz — longer range, slower speed
• 5 GHz — shorter range, faster speed

If possible, connect the extender to the 5 GHz band for better throughput. If your devices are far away, use 2.4 GHz but accept slower rates.

2. Optimal Placement

A common mistake is placing the extender too close to the router (crowding) or too far away (weak signal).

Best practice:

• Place the extender where it still gets a solid signal from the router (about 40–60% signal strength)
• Not too far, not too close

3. Scan for Channel Congestion

Neighbors’ Wi-Fi networks can crowd popular channels — especially on 2.4 GHz (channels 1, 6, 11).

• Use a Wi-Fi scanner app
• Switch the router and extender to a less crowded channel
• Save and reboot devices

4. Limit Bandwidth-Heavy Devices

Streaming, downloads, gaming, and cloud backups can saturate your network.

• Log into the router’s admin panel
• Activate QoS (Quality of Service)
• Prioritize essential traffic

5. Firmware Updates

Old firmware leads to inefficiencies.

• Update both your extender and router firmware
• Confirm compatibility between firmware versions

6. Avoid Wireless Interference

Keep extenders away from:

• Bluetooth hubs
• Microwave ovens
• Metal cabinets
• Baby monitors

Final Performance Tips

• Check speeds using speed test apps near the extender
• Compare results with and without the extender
• If loss is too great, consider a mesh Wi-Fi system instead of a basic repeater

By following these optimization steps, MyWi-Fiext.net users can significantly improve post-setup speeds and enjoy smoother browsing and streaming.
