How to Prevent Hackers from Breaking into Your Wi-Fi Network

Most people have one or more Wi-Fi networks in their homes. Others use apps like Wi-Fi map to get access to millions of free hotspots which can be found everywhere in the world.

But let’s assume that you run your own Wi-Fi network, and you are interested in hardening its security. The first step is to set a strong router password.

Some people don’t even bother to change the default router password. Others may do it, but they set a weak password, and then they forget it. If you fall into the latter category, you will need to reset your router.


The good news is that almost any router in existence comes with a reset switch. It’s usually a recessed button that can be pushed using a paperclip. So locate that tiny hole in your router’s case, and then push that switch for about 20 seconds to reset the router to its default settings.

Okay, I hear you. You threw the manual away together with the router box the very same day you’ve installed your router. So now you don’t know your router’s default password. If this is the case, head over to and you will hopefully find the needed password.


It’s time to log into the admin panel and set a strong password that will prevent hackers from getting access to your router.

Pro tip: stay away from routers that come with a built-in network password. They’re usually offered by your ISP, but since the Wi-Fi password can’t be changed, it’s easy for a hacker to get into your network anytime he or she wants to.

We are now ready to change the Wi-Fi password. Believe it or not, this is the easiest method that prevents hackers from getting access to our computers, devices and files. And if you change it every few months or so, you have already won 99% of the battle against them.

Many hackers use Aircrack to try and get your Wi-Fi password. This piece of software has been the hackers’ friend for many years, being responsible for many WEP password cracks. Still, the newest version of the tool can also crack WPA – PSK keys.

Aircrack is not easy to use, but it’s a useful tool if you plan to run comprehensive security tests on your Wi-Fi network. You’ll need a couple of RP-SMA cables and a pack of high gain antennas if you want to run your test from a distance, the way these tests are usually done.


It’s important to understand that Aircrack only works with Wi-Fi adapters that support packet injection, though.

Kali is a free, Linux based network penetration set of tools. Hackers use it to try and get into other people’s networks, but you can use it to test and harden your network security. And the good news is that Kali can boot from an USB stick, so there’s no need to install it on your computer.


Armed with this info and tools, I am sure that you’ll be able to run your own network security tests, preventing other people from logging into your Wi-Fi network.
