Reset Your Router Remotely Using Your Phone

Have you ever been away on a trip and realized that your internet was down due to issues with your router or cable modem? How do you regain access when you're miles away from home?

For many, the answer might lie in a single-board computer (SBC) running Linux, combined with a few smart scripts and passive components. This DIY solution can perform internet tests and automatically reset your router if necessary.

Why You Might Need This Solution

When your home network is down, you need a way to regain internet access without physically being present. A mobile app-based solution can help you manage your router remotely, saving you from the hassle of asking a family member to drive over and reboot the device.

DIY IoT Solution for Routers

The DIY solution involves setting up a small, internet-connected device that can monitor the internet status and automatically reboot the router if necessary. This is particularly useful when you're on a trip or out of the house.

Theoretical Approach

The idea is to set up a system that performs several internet tests (possibly from multiple websites or services) to determine if the connection is stable. If the tests fail, the router is power-cycled. The goal is to avoid repeated cycles, so the system is designed to pause and retry after a certain interval.

Building the System

To build this system, you'll need:

Single-board computer (SBC) Linux operating system Python scripts set as cron jobs Passive and mechanical components for safety

The process involves writing and executing Python scripts to run internet tests. If the tests fail, the system will reboot the router. Simultaneously, it ensures that the power cycle process doesn't run indefinitely by setting timers and intervals.

Alternative Solutions

If a DIY solution isn't appealing, another option is to use a cellular module. You can set this up with an account on your phone plan and control the router remotely using a phone call or text message. While this might be more costly, it provides a simpler and more direct way to manage your router from any location.

Basic Manual Method

For those who prefer a straightforward manual method, here is how you can reset your router using your phone:

Step-by-Step Guide

Open your web browser on your phone. In the address bar, enter the default gateway IP address of your router. Enter your router's username and password when prompted. Look for an option like 'reboot device' or 'power cycle' in the router's settings menu. Click on the 'reboot device' option and your router will restart.

While this manual method works, the DIY IoT solution offers more automated and frequent monitoring, making it a preferable choice for those who travel often or are concerned about network uptime.

Conclusion

Whether you choose to build your own IoT solution or opt for a more convenient remote access method, resetting your router remotely can significantly enhance your travel experience and peace of mind. The key is to pick a solution that suits your needs and circumstances.
