How to Configure Router to Use WPA2?

Many individuals are unconcerned about Wi-Fi network security and keep all settings default and security set to ‘open’ until something disastrous occurs. It is frequently too late.

This indicates that you are aware of potential threats and are looking for strategies to mitigate them. So, let’s get started.

Wi-Fi security evolution

WiFi security

A wireless network is created when you connect a router to your office or home. All devices that are connected to the router form this network. You can make it secure or open depending on your security concerns.

Let’s go over your selections, starting with the worst and ending with the greatest and newest:

Anyone within the signal range will be able to use it if the settings are left on ‘Offen.’ A password will not be required. Uninvited visitors are unlikely to get within range if you reside in a rural location. In any event, you’ll need some defense against nasty folks with computer abilities.

In 1999, the Wired Equivalent Privacy Protocol was created to enhance the security of wireless networks. It used a 40-bit encryption key. Hackers quickly cracked it, making it obsolete. You will have to search hard to find a network device that supports WEP. Yes, that’s how bad it is.

WPA (Wi-Fi Protected access) was the next step in Wi-Fi security evolution. WPA, or Wi-Fi Protected Access, was superior due to the use of TKIP (Temporal Key Integrity Protocol) encryption. The game of cat-and-mouse between security engineers and hackers quickly turned into a game of cat and mouse.

Because the protocol was vulnerable to numerous hacker assaults, WPA2 and the better encryption AES – Advanced Encryption Standard protocol were developed. WPA2 is sufficient security for most applications, despite its weaknesses.

Safety improvement is a constant process. WPA3, which is the latest version, was launched in 2018. It represents the advancement of internet security and encryption for wireless network networks.

What are the benefits to choosing WPA2 protocol?

This question can be summarized in two words: compatibility and adequacy.

WPA2 will therefore be adequate for most applications, with little or no compatibility issues.

All devices that bear the Wi-Fi trademark must support it since 2006. There are very few chances that you will find a device that uses Wi-Fi, but is not compatible with WPA2. An audio/video receiver is the only thing that comes to mind. These are not the types of devices that you will change often.

Imagine that you have an older device such as an AV receiver that has Wi-Fi connectivity. You will need to configure your router so that it uses a WPA2/WPA combination in order to allow access to older devices as well as newer ones.

However, you should only do this if you truly need that obsolete device on the network and are unable to upgrade or replace it. ‘A chain is just as strong as its weakest link,’ therefore enabling WPA to allow access to an old device can reduce the overall level of security on your network.

How can you set up your router to use WPA2?

If you need to alter network settings or select options on your router, go to the Admin panel, commonly known as the Admin console.

In some cases, router settings can be accessed via a mobile app. We will however use the internet browser to notify users of all models and makes. To change network security settings, you can do this on any device that is connected to that router.

To get to the admin panel, you’ll need to know two things:

  1. Set default IP address for router
  2. Administrator username and password

1. Every router manufacturer has its own IP address to access the Admin panel. The default IP address is usually stated on a sticker on the back of your router under the term “default IP address.” If your router’s default IP address isn’t listed on the back, type the manufacturer’s name and ‘default IP address’ into Google’s search box to get it.

Some cases will write the default IP as a domain. In others it will be written in a series number (e.g..

2. You will need to have the default admin username, password and sticker on the back of your router. If you don’t find it, use Google the same way as for the default IP address.

NOTE:A second-hand router could have its default administrator username or password changed. If this is the case, you’ll need to reset the router by pushing the reset button for a few seconds. You will be able to restore the factory settings of the router by doing this. You will need to reconfigure your network (SSID, admin username, password, and any other settings) from scratch.

Once you have found the default IP Address and administrator username, password, you can open any internet browser connected to your router and enter the default IP address in the address bar. To continue, you will be taken to a login page. Here you must enter your username and password.

Every manufacturer has their own unique user interface. They can also vary within the same manufacturer. You will still find the information you need under Wireless security settings, Wireless authentication or another similar category.

As an example, consider the TP-Link single band router:
Click on ‘Network,’ then on ‘wireless security,’ on the left side of the screen.
If you see WPA, WPA2, WPA3, and other alternatives to pick from, you’ve come to the proper location.

How to Configure Router to Use WPA2

Next, choose WPA2-PSK wireless security and AES encryption. Then restart the router as per the instructions.

PSK is an abbreviation of Pre-Shared Key. This option is ideal for small offices and homes as it doesn’t require authentication servers.

As we said, you can allow devices that were made before 2006 to access the network. If you have such a device, you won’t be able to use only the WPA2 protocol. Instead, you’ll need to enable both WPA2 and WPA and both TKIP and AES encryption. Remember that these settings can reduce security as WPA/TKIP may not be as secure as WPA2/AES.


Many people don’t realize that hackers can access their Wi-Fi networks and steal personal information. We should all improve our wireless security at the highest level possible to avoid this.

WPA2 protocol, AES encryption offer a compromise between security and compatibility. They must be supported by all Wi-Fi devices made after 2006.

Access the Admin Panel using any internet browser from any device connected to your router to enable WPA2/AES.

In a browser, type the default IP address in the address bar. You will then be taken to a login screen where you need to enter your administrator username and password.

On the router’s back, you will find the default IP address, admin username and password. If not, use Google to find them by typing in the manufacturer’s name and ‘default IP address into the search. You can also search for administrator usernames and passwords.

Different manufacturers’ user interfaces change, but the choices you need should be found under ‘wireless security,’ Wireless authentication, or something similar.

Choose from the available options WPA2-PSK, AES.

You can connect any device that was manufactured prior to 2006 to a wireless network using the WPA2/WPA/PSK combo and AES/TKIP encrypted. WPA2-PSK/AES is a better choice.

After choosing the proper settings, follow instructions in the Admin panel to save changes and reboot the router.
