How to Enable Your Wireless Router’s Built-in Firewall

Have you ever wonder what that blinking wireless router you have at home can do? Yes, you know what that’s for, it wired your whole home network connection and makes you wireless around the house. But what about cyber protection? Are you fully equipped to defend yourself against cyber criminals or internet hackers? Aside from forgetting to bring my phone charger when I leave home, the other most important thing I am scared of is being hacked and unprotected from internet malware and viruses. If you are on the same board with me, then you would need to start thinking of setting up router firewall at your home too.

I always thought that to set up router firewall at home, I need to call a professional which would cost me a lot of dimes. Since I like to use my money for other stuff (such as upgrading my phone to that sparkling iPhone X people have been raving about), I prefer to take things on my own and see if I can set up the router firewall by myself. So, I did a lot of research online, read a lot of how-to articles, and watched a bunch of YouTube videos on how to enable my wireless router’s built-in firewall.

What is Firewall

Before I share you how to do it, let’s start slow. Some of you might wonder, what the heck is a firewall? It sounds dangerous.

Worry not, it doesn’t involve any fire at all. I actually don’t understand why they used the term fire-wall for this, but it sounds really cool, so who am I to object?

Anyway, in my research, I found this website,, that describes what fire-wall is. Quoting the website, a firewall is a system created to protect your internet network and work as a barrier or shield to ensure your phone or other gadgets are protected from the data-based malware dangers around the cyber world. Firewalls serve to monitor the data exchanged between your computer routers, to see whether these data are safe or not based on the requirements that have been set up beforehand. Based on these requirements, firewalls will decide which data are allowed to get in or get blocked.

How it works

To keep it simple, firewalls basically serves as the gatekeeper for incoming loads of data, making sure that none of these data contains malware that could harm your home network and gadgets, or even steal your information stored in your computer. If you have children at home, a firewall can even help to block age-inappropriate or immoral contents as well. Cool, huh? That is why setting up router firewall at home is important, considering the amount of private information you keep inside your home computers or phone.

So now, how to set up your own firewall system at home? First of all, you might already have a firewall installed on your computer. If your PC or tablet is running a modern operating system, it must have a built-in firewall feature already. That’s what we called with a software-based firewall.

Getting ready

However, you need to ensure that your wireless router is protected too because that is basically where a load of data or coming to your server and gadgets. This is what we called with a hardware-based firewall. Should we enable both firewalls? I would say so because each firewall provides unique benefits that will complement each other. One will protect your computer directly from virus attacks, while the other one will protect your network from worms or malware right before they reach your computer. That is why I think it’s a good idea to run both firewalls.

For software-based firewall, you don’t have to worry about setting it up. Most operating system nowadays comes with a firewall, which you can enable and disable easily. For hardware-based firewall such as your wireless router, the current wireless router versions sold in the market today already come with a firewall setting. But will it be easy to configure? I know the feeling.

It took time for me to set all my gadgets connected to the wireless connection at home. How will I be able to configure a built-in firewall using my wireless router? It sounds so difficult. However, after a couple of days of research on this topic, I found out that it is actually very easy to do, you don’t have to do a lot of complicated stuff to enable your wireless router’s built-in firewall.

How to set it up

To set up your hardware-based firewall, you need to access your router by using your PC’s web browser. Usually, in the manual guide that comes with the wireless router, they will provide the access link, so you can see the router’s firewall configuration screen. You must be connected to your high-speed internet to do this, by the way.

Now, once you have opened the Security page, look for an option labeled “SPI Firewall” or just “Firewall”. Enable that option and then don’t forget to save the settings. After you saved the settings, click on “Apply for the changes “or “Done” button (the instructions are different in each wireless router) to make sure that it works. Once you click that button, your router will immediately reboot itself and your fire-wall is enabled.

But wait! You are not done yet! After you enabled your router firewall, you must go back to the admin panel to configure your setting and set it up according to your requirements. Once you’re done with the configuration, test your firewall to make sure that it is working as you want it to be.


Sounds complicated? Trust me, it’s actually not. You just have to follow all the instructions, make sure you know what kind of requirements you want for your fire-wall setting, and voila! You’re protected! Once you have a built-in fire-wall at your home, you can worry less about virus attacks, receiving spam emails, or even hacker threats. You can store that important information securely without worrying someone will steal that information. As someone who enjoys online gaming. A fire-wall is also perfect for me because it helps to protect my gadgets and network from malware. Irresponsible people have developed it to target online gamer.

So, to sum it up, I think enabling router fire-wall at home is very important for so many reasons. And if I can configure it by myself, I am sure you will be able to do it yourself too.
