Our routers are from many brands, including Asus, Digisol, Netgear, TPlink, Linksys, Dlink, and others. They all have unique stock firmware and security features. But as human beings, we usually go buy the less expensive ones may be to save money or may be because we don't have enough money to buy the expensive ones. But the problem arises here since their functionality and security features are much more limited than the expensive ones, making them unreliable. One cause for this is the availability of router firmware upgrades and patches.
Most of the times, either the manufacturers do not provide updates for this router firmware, or the users are unaware of the fact that the manufacturer has released an update. Occasionally, well-known router manufacturers do not care to address security flaws, especially in routers that are a few years old. In such cases, hackers may engage in hostile activities in order to compromise your network's security.
We have to know that every router has its own set of functions and firmware. Sometimes the router has restricted functionality, and you'll need an alternative open-source firmware to get the finest security and customization choices. Open-source software has a variety of functions and security features. It improves a router's speed and performance. That is why in this article today, we have the best open source router firmware for you.
Best Open Source Firmware for Router 2024
First of all, before we start with these open source firmware for router, let's introduce you step after step starting with what a router is.
What is a Router?
A router is a networking device that sends data packets from one computer network to another. On the Internet, routers are responsible for traffic directing. Data packets are used to send data over the internet, such as a web page or an email. A packet is sent from one router to another through the networks that make up an internetwork (such as the Internet) until it reaches its destination node.
Does it actually mean that a router and a modem are similar? Not actually. In the table below are some of the few differences though they are similar in many other things.
| Router | Modem |
|---|---|
| Brings internet to your devices | Brings Internet to your home |
| Assigns local IP addresses | Assigns Public IP addresses |
| Uses LAN network | Uses WAN network |
What is a Router Firmware?
The preinstalled, embedded software that controls routing protocols, administrative functions, and the router's security mechanism is known as router firmware. Firmware is the most important program in the read-only memory of a router (ROM).
The same way a firmware is an embedded software, but a firmware is different from a software. And so, one should not tell you that a firmware is a software. That is why a firmware refers to data that is fixed as part of a hardware device, whereas software refers to data that is used for interaction, productivity, and activities such as word processing, video editing, music listening, and video conferencing.
Embedded systems (such as traffic lights, consumer appliances, and digital watches), computers, computer peripherals, mobile phones, and digital cameras are all examples of devices that contain firmware. The control module for these devices is provided by the firmware present in these devices.
What is an Open Source Router Firmware?
Custom router firmware, aftermarket router firmware, and alternative router firmware are all terms used to describe open source router firmware. These types of firmware can be a good replacement for the router's stock firmware.
Because it is based on Linux, the custom router firmware not only offers you with the greatest possible security features, but also allows you to alter them to make your router more advanced or add some additional functions to fit your office or home needs.
What are some benefits of using Open Source Router Firmware
They are;
- Bugs in stock firmware are removed.
- Removes any spying restrictions or backdoors imposed by the government.
- Support for Telnet/SSH caching
- Integration of a hotspot

Advantages of Changing Your Router OS
You might wonder what's wrong with the firmware that came with your router by default. Many users believe that they should have the ability to control the software that runs on their devices and, if necessary, make changes to improve it. Third-party firmware, on the other hand, provides consumers with additional features such as bandwidth restrictions.
- Allocate bandwidth.
- Parental authority.
- Increase the strength of wireless wifi signals.
- Enable password-protected internet access, among other things.
- Convert your home router into an enterprise-class equipment.
