Complete Guide to 5 Home Network Mistakes That Slow Down Wi-Fi and How to Fix Them

If your home internet connection has stability and speed issues, the cause is often not the line provided by your ISP, but errors in the internal network configuration. This guide will show you how to solve five common problems that can significantly improve your browsing experience.

These tips are useful for anyone with a home network, especially if multiple devices are used simultaneously for activities such as streaming, gaming, or smart working. The proposed solutions do not require advanced technical skills and can be implemented with tools already available.

By the end of this guide, you will be able to optimize your Wi-Fi network, improving coverage, speed, and connection stability without having to change your subscription or buy new devices.

Prerequisites

• Hardware:
  • Wi-Fi Router
  • Ethernet Cable
  • Any Wi-Fi repeaters or mesh systems
• Software:
  • Access to router settings

PROCEDURE: Numbered Step-by-Step Explanation

Follow these steps to improve your home internet connection without changing your subscription:

• Position the router correctly
  • Move the router to the center of the house, possibly at chest height.
  • Use a longer Ethernet cable if necessary.
  • Periodically reboot the router.
  • Check and update the router firmware.
• Configure alternative DNS servers
  • Replace the provider's DNS servers with alternatives like Cloudflare or Google.
  • Configure encrypted DNS (DNS-over-HTTPS or DNS-over-TLS) for greater privacy.
• Manage bandwidth with QoS
  • Move daily-use devices to the 5 GHz band.
• Choose a mesh system instead of a cheap Wi-Fi repeater
  • Buy a mesh system to cover the entire house.
  • Connect at least one of the nodes to the main router via Ethernet cable.
• Check and replace damaged cables
  • Check Ethernet and coaxial cables for any damage.
  • Replace damaged cables.
  • If the router is outdated, consider replacing it with a newer model.

Verification and Troubleshooting

After configuring your home network following the previous tips, it is important to verify its operation and resolve any issues. Here's how to proceed.

Connection Test

• Check connection speed: Use online tools like Speedtest to measure download and upload speeds. Compare the results with those promised by your subscription.
• Check signal stability: Perform ping and jitter tests to verify connection stability. Tools like PingPlotter can help with this.
• Test Wi-Fi coverage: Move devices to different parts of the house to verify signal quality. Use apps like Wi-Fi Analyzer to identify crowded channels.

Problem Resolution

• Router not responding: If the router does not respond, reboot it by pressing the reset button for 10 seconds. Make sure the status lights are on and stable.
• Wired connection issues: Check Ethernet cables for any damage. Replace them if necessary and ensure they are connected correctly.
• Wireless connection issues: If Wi-Fi is weak, check the router's position and move interfering devices. Consider using a mesh system if dead zones persist.
• Slow DNS: If web pages load slowly, change the DNS servers as explained in the previous section. Try Cloudflare or Google DNS servers.
• QoS not working: If bandwidth priority does not seem to work, check the QoS settings in the router's admin panel. Make sure you have not set thresholds too low.

Periodic Maintenance

• Update router firmware: Periodically check if firmware updates are available for your router. Updates can improve performance and security.
• Regularly reboot the router: Reboot the router at least once a week to maintain optimal performance.
• Monitor bandwidth usage: Use monitoring tools to identify devices or applications that consume too much bandwidth. Limit the use of these devices during peak hours.

By following these steps, you will be able to verify the proper functioning of your home network and effectively resolve any issues.

Educational Summary and Call to Action

By following these five steps, you will have optimized your home network without having to change your subscription or expensive hardware. Here is a summary of the key actions:

• Alternative DNS: Configure DNS servers like Cloudflare or Google to improve speed and privacy.
• QoS and bandwidth: Use Quality of Service to prioritize important devices and consider using the 5 GHz band.
• Cables and hardware: Verify the integrity of cables and consider upgrading the router if necessary.

Put yourself to the test and start with the simplest step: moving the router. You will immediately see an improvement in the stability and speed of your connection.
