Changing your wireless network encryption type is the first step after purchasing a new router. Most users leave the factory settings or select the standard protocol. WPA2, even if their equipment supports more modern and secure standards. This creates vulnerabilities that attackers can exploit to intercept traffic.
In modern conditions, the use of outdated security algorithms, such as WEP or WPA, is considered a critical error. These protocols were hacked several years ago, and the tools to bypass them are available to anyone on the internet. Therefore, the transition to WPA2-AES or the newest WPA3 is a mandatory requirement of digital hygiene.
Changing settings doesn't require in-depth networking knowledge, but it does require attention. Incorrectly selecting the right settings can result in older devices simply losing visibility into your network. In this article, we'll cover the step-by-step process, the differences between protocols, and the nuances of configuring equipment from different manufacturers.
Differences between WiFi security protocols
Understanding the differences between encryption standards helps you find the optimal balance between compatibility and security. The oldest standard WEP (Wired Equivalent Privacy) was introduced back in 1997 and is now considered completely insecure. Its encryption algorithm can be broken in minutes, even on low-end hardware.
Standard WPA (Wi-Fi Protected Access) replaced WEP as a temporary solution. It uses the protocol TKIP, which dynamically changes encryption keys, but it has long since fallen short of modern security requirements. Using this mode is now only justified in exceptional cases, such as when connecting to a very old device that doesn't support new standards.
Today the gold standard is WPA2 with encryption algorithm AESThis protocol provides reliable data protection and is supported by the vast majority of devices released in the last 15 years. This mode is recommended by default if your router doesn't support newer versions.
The latest standard WPA3 was introduced in 2018 and is gradually being implemented into mass-market hardware. It addresses the vulnerabilities in the handshake protocol present in WPA2 and provides better protection against brute-force password attacks. However, Not all older gadgets (released before 2018) can work with WPA3, which may create connection problems.
⚠️ Attention: When selecting "WPA2/WPA3 Mixed" mode, the router attempts to negotiate the best protocol for each device. This is the best option for compatibility, but it could theoretically be vulnerable to downgrade attacks if not configured correctly.
The choice of a specific encryption type directly affects network speed. Algorithm TKIP, used in older standards, artificially limits WiFi speed to 54 Mbps, even if your router supports gigabit speeds. Switching to AES removes this limitation and allows you to unlock the potential of modern equipment.
Preparing to change router settings
Before making any changes to your wireless network configuration, ensure a stable connection to the router's administrative panel. It's best to configure the settings by connecting your computer to the device via LAN cableThis will eliminate the risk of losing your connection when changing encryption settings and Wi-Fi is temporarily disconnected.
If a cable connection is not possible, make sure you are in an area with a strong signal. Write down or copy your current settings so you can quickly restore them if you make a mistake. It's also recommended to have your router's administrative password handy.
It's important to check the list of connected devices. If your network includes critical devices that can't be quickly reconfigured (such as smart home systems or CCTV cameras), changing the encryption type may temporarily disrupt their operation. In such cases, it's best to schedule the update for a time when you can physically access each device.
☑️ Check before setup
Some providers provide subscribers with routers with limited access to settings. In this case, the standard browser login procedure may not work, requiring you to contact technical support or use a special operator app.
Login to the router's administrative panel
To get started, you need to open your browser and enter your router's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, however, the address may vary depending on the model and manufacturer. The exact address is usually indicated on a sticker on the bottom of the device.
After entering the address, the system will ask for your login and password for authorization. The factory default data is also on the sticker, but if you've previously changed it, use your current credentials. If you forget your password, you'll have to reset the router to factory settings, which will also reset the encryption type to its original value.
Interfaces from different manufacturers vary significantly. TP-Link settings are often located in the section Wireless or Wireless mode. U ASUS And Keenetic look for the tab WiFi or Home network. MikroTik requires going to the menu Wireless and opening a specific access point.
In modern routers with dual-band support (2.4 GHz and 5 GHz), encryption settings can be separated into different tabs or combined into one. Make sure you adjust settings for both bands if you want to ensure a consistent security policy across your entire network.
⚠️ Attention: Firmware interfaces are constantly updated. The layout of menu items may differ from that described. If you can't find the setting you need, use the settings search or refer to the documentation on the manufacturer's official website.
Step-by-step instructions for changing the encryption type
Once you've entered the desired section, find the setting responsible for security. It may be called Security Mode, Encryption, Wireless Network Security or Wireless SecuritySelect the desired protocol from the drop-down list. For maximum compatibility and security, the optimal choice is WPA2-PSK [AES].
If your equipment supports the new standard, select WPA3-Personal or mixed mode WPA2/WPA3Please note that when selecting WPA3, some older devices (such as old printers or IoT light bulbs) may stop connecting. In this case, you will need to revert to WPA2.
After selecting the encryption type, be sure to check the password field. Sometimes, when changing the protocol, the router may reset the password to the factory default or make it blank. Make sure you set a complex password that contains mixed-case letters and numbers.
Don't forget to press the button Save (Save) or Apply (Apply). The router will warn you that the wireless connection will be interrupted. Confirm the action. After a few seconds, the network will restart with the new settings.
| Protocol | Algorithm | Security | Compatibility |
|---|---|---|---|
| WEP | RC4 | Critically low | Devices before 2004 |
| WPA | TKIP | Low | Old gadgets |
| WPA2 | AES | High | Almost all devices |
| WPA3 | GCMP-256 | Maximum | New devices (after 2018) |
What should I do if I lose my internet connection after changing the settings?
If your internet connection is lost, there may be a problem with your ISP or the router may not have applied the settings correctly. Try rebooting the router using the power button. If that doesn't help, perform a factory reset (hold the Reset button for 10 seconds) and set up the network again.
Setting up encryption on different router models
The setup procedure may vary depending on the brand. On routers TP-Link with the green interface you need to go to Wireless -> Wireless Security. There you select the option. WPA/WPA2 - Personal (Recommended). In the encryption version (Version) it's better to leave it Automatic, and in the algorithm select AES.
For devices ASUS the path looks like this: Additional settings -> Wireless network -> tab GeneralIn the field WPA security method we choose WPA2-Personal or WPA3-Personal. Here you can also set up a separate guest network with different security settings.
In routers Keenetic (formerly ZyXEL) you need to go to the menu My Networks and WiFi. In the section Home network there is a block Network protectionThe system will automatically suggest a recommended protection level. Advanced users can fine-tune settings via the command line, but the graphical interface is sufficient for changing the encryption type.
Routers from MikroTik require more careful attention. On the menu Wireless you need to double-click your access point (ap1 or). On the tab Security Profile a profile is created or edited. In the parameter Authentication Types the required standards are selected, and in Unicast Ciphers And Group Ciphers must be indicated aes-ccm.
Compatibility issues and their solutions
Switching to stronger encryption protocols often causes problems with older devices. If your smartphone or laptop stops connecting to the network, it likely doesn't support the selected algorithm. AES or standard WPA3First, try updating the WiFi drivers on the problematic device.
If updating doesn't help, the only solution is to create a separate guest network with less restrictive settings (e.g., WPA2-TKIP) exclusively for the old device. However, this reduces overall security, so keeping such a network enabled permanently is not recommended.
A common issue is "sticky" settings on the client device. The phone or tablet may remember the old encryption type and try to connect using it. In this case, find your network in the WiFi list on the device and select the option. Forget the network (Forget Network) and enter the password again.
In some cases, the conflict arises due to the function WPSThis standard allows for connection with the push of a button, but it has vulnerabilities and may conflict with WPA3 settings. If you don't use WPS connections, it's best to completely disable this feature in your router settings.
⚠️ Attention: Internet of Things (IoT) devices such as smart plugs, cameras, and sensors often have poor support for modern standards. Before making the global transition to WPA3, check the specifications of your smart gadgets.
Frequently Asked Questions (FAQ)
Can changing encryption slow down the internet?
Changing the encryption type itself doesn't slow down your internet. In fact, switching from TKIP to AES can increase speeds by removing software limitations. However, if you select WPA3 on an older router with a weak processor, the CPU load may increase, which could theoretically reduce performance with a large number of connections.
Do I need to change my password when I change the encryption type?
Technically, changing your password isn't necessary; the system will accept the old one. However, if you change security settings, it's a good practice to also change the password to a more complex one. This ensures that previously connected but unwanted users can't exploit the vulnerabilities of the old protocol.
Why does my phone say "Failed to connect" after changing settings?
This means your phone and router can't agree on a common encryption language. Most likely, you've enabled "WPA3 Only" mode, but your phone doesn't understand it. Go back to your router settings and select "WPA2/WPA3 Mixed Mode" or temporarily switch back to "WPA2-Personal."
Is WPA2 safe to use in 2026?
Yes, using WPA2 with the AES algorithm is still considered safe for home use. Vulnerabilities reported in the news (such as KRACK) require complex attacks and are usually patched with firmware updates. WPA3 is preferable, but WPA2-AES is not a critical vulnerability.
