6 Best Alternative Open Source Router Firmware (2024)

Firmware is basically the OS that comes on the router pre-installed. Now each manufacturer carries its own version. Just like OS there on your phone device or personal PC, it controls all the inner workings of the device. It performs the following 3 main tasks:

  1. Router communicated with the device wirelessly.
  2. Protects the network from malware, viruses and other threats.
  3. Provides administrator software which we use in order to manage the settings of the router.

About your Router Firmware

For mere performance, we need to update this. We all want our wifi to be fast and accessible from each room, now, what the update does is provide bug fixes and technology improvements which lead to a better experience for the entire family.

Another reason is the security protection that it provides. Today threats are there for online security and these have mainly target home Wi-Fi networks. Like, your router can get in the hands of a security theft if it is not secured properly. These can then be further used along with thousands of others hijacked to launch malicious cyberattacks there on the organization’s sites and networks.

The best way to save yourself from this is to always have the latest version of firmware installed.

Remember: The router can get hacked without you knowing if the firmware is not up to date.

Benefits of replacing your Router OS

  1. Bandwidth quotas.
  2. Bandwidth allocation.
  3. Parental control.
