How to Change Wi-Fi Security Type: Choosing the Optimal Security Protocol

Wireless networks have become an integral part of our lives, but their security often remains a secondary concern. Meanwhile, Wi-Fi security type determines how easily attackers can intercept your traffic or connect to your network without permission. If you're still using an outdated WEP or even WPA, your data is at risk - modern hacker tools can hack such networks in minutes.

In this article we will look at, How to change Wi-Fi security type on a router of any manufacturer - from budget ones TP-Link And D-Link to bonuses ASUS RT-AX88U or Netgear NighthawkYou'll learn which protocol to choose in 2026, how to avoid common setup mistakes, and what to do if your devices stop connecting after changing settings. We'll also reveal a hidden vulnerability in WPA2/WPA3 mixed mode that is rarely warned about in manufacturer manuals.

Why is it important to update your Wi-Fi security type?

According to the study Kaspersky By 2026, more than 40% of home networks will still use obsolete protocols, which can be hacked in 5-10 minutes using free utilities like Aircrack-ng or ReaverHere's why changing your security type isn't a whim, but a necessity:

• 🔓 WEP (Wired Equivalent Privacy) - is hacked for 2-3 minutes even on a low-end laptop. Support is retained only for compatibility with older devices (for example, printers from 2010).
• 🛡️ WPA (Wi-Fi Protected Access) - the first step to security, but vulnerable to attacks KRACK (Key Reinstallation Attacks). Hacking takes anywhere from 15 minutes to several hours.
• 🔒 WPA2 (AES-CCMP) — de facto standard since 2006. Reliable if used AES, and not TKIPHacking is only possible with a weak password.
• 🚀 WPA3 — a modern protocol (since 2018), resistant to most attacks. Mandatory for networks with devices on Wi-Fi 6/6E.

Transition to WPA3 not only protects against hacking, but also improves network performance. For example, in tests SmallNetBuilder routers with WPA3 showed 10-15% higher data transfer speed compared to WPA2 under the same conditions. This is due to optimized encryption algorithms.

⚠️ Note: If your router was released before 2018, it may not support WPA3In this case, the optimal choice is WPA2-PSK (AES)Check the model on the manufacturer's website.

What type of Wi-Fi security should you choose in 2026?

The choice of protocol depends on age of the router, supported devices And safety requirementsBelow is a comparative table with recommendations:

Particular attention should be paid to WPA2/WPA3 mixed modeIt seems convenient, but it has a critical drawback: When a device connects via WPA2, the network automatically switches to a less secure protocol for all clients.This means that even if your smartphone supports WPA3, he will use WPA2, if an old device connects to the network.

Recommendations for selection:

• 🏠 Home network: WPA3 (if all devices are newer than 2018) or WPA2 (AES).
• 🏢 Office: WPA3-Enterprise with radius server for additional authentication.
• 🎮 Game consoles: WPA2 (AES) - some models (for example, Nintendo Switch 2017) do not support WPA3.
• 🖨️ Old printers/scanners: allocate a separate guest network for them with WPA2.

Step-by-step instructions: how to change the security type on your router

The setup process is the same for most routers, but may vary slightly depending on the firmware version. We'll cover a general procedure, taking into account the specifics of popular brands.

Step 1: Login to the router's web interface

1. Connect to the router's network via cable or Wi-Fi.

2. Open your browser and enter the following in the address bar:

• TP-Link, ASUS, Netgear: 192.168.1.1 or router.asus.com
• D-Link, Zyxel: 192.168.0.1
• MikroTik: 192.168.88.1

3. Enter your login and password (usually admin/admin, if not changed). On some models (Xiaomi, Huawei) the data is indicated on the sticker below.

Step 2: Go to the Wi-Fi settings section

The path may vary, but typically it is:

• TP-Link: Basic → Wireless or Advanced → Wireless Settings
• ASUS: Wireless → General or Wireless → Professional
• D-Link: Wi-Fi → Basic Settings
• Keenetic: Home Network → Wi-Fi Network

Step 3: Select the security and encryption type

Find the fields Security Mode (or Network Authentication) And EncryptionOptimal settings:

• 🔹 Security Mode: WPA3-Personal (or WPA2/WPA3-Personal for compatibility).
• 🔹 Encryption: AES (never choose TKIP!).
• 🔹 Wi-Fi Password: create a password of length 12+ characters with numbers, letters and special characters.

Make sure AES encryption is selected|

Password contains ≥12 characters|

Disable WPS (if not used)|

The current configuration is written down (in case of a reset)

-->

Step 4: Save and Reload

Click Save or ApplyThe router will reboot (1-2 minutes). After this, all devices will be disconnected and will need to be reconnected with a new password.

⚠️ Note: If some devices stop connecting after changing the security type, please check their support WPA3. For example, Amazon Echo first generation (2015) does not work with WPA3 - it will require a separate network.

What to do if your router doesn't support WPA3?

If there is no option in the settings WPA3, update your router firmware to the latest version. For models older than 2018 (e.g., TP-Link Archer C7 v2) support WPA3 This may appear after an upgrade. If the update doesn't help, use WPA2 (AES) and enable additional security measures:

• 🔄 Change your password regularly (every 3 months).
• 🚫 Turn it off WPS — is a vulnerable authentication protocol.
• 📡 Hide the SSID (disable broadcast) for the guest network.

Customization features for popular brands

Router manufacturers often modify the interface, adding unique features. Let's explore the nuances for the most common brands.

TP-Link (Archer, Deco, TL-WR)

In routers TP-Link The security setting is hidden in the section Wireless → Wireless Security. Peculiarities:

• 🔄 In models with OneMesh (For example, Deco X60) when changing the security type, the setting is automatically applied to all network nodes.
• 📶 For dual-band routers (Archer C6) settings 2.4 GHz And 5 GHz are changed separately.
• 🔧 In newer firmware than 1.1.0 mode available WPA3/SAE — the most secure option.

ASUS (RT-AX, RT-AC, ZenWiFi)

ASUS offers advanced security options in the section Wireless → Professional:

• 🛡️ Function Protection against brute-force attacks Blocks password guessing after 5 unsuccessful attempts.
• 🔄 In mesh systems ZenWiFi changes are applied to all nodes synchronously.
• 📡 You can set a separate security type for the guest network (for example, WPA2 for older devices).

Keenetic (Giga, Hero, Viva)

Routers Keenetic use a proprietary OS NDMS, where the security settings are hidden in Home Network → Wi-Fi Network → Security:

• 🔐 Supported WPA3-Personal And WPA3-Enterprise (for offices).
• 🔄 When changing the security type, the system prompts you to export the current configuration.
• 📊 There is a built-in Wi-Fi Scanner, which shows the vulnerabilities of neighboring networks.

MikroTik (hAP, RB, Chateau)

Setting up on MikroTik requires knowledge RouterOS. Path: Wireless → Security Profiles:

• 🔧 Here you can create multiple security profiles for different SSIDs.
• 📡 Rare modes like WPA2-EAP for corporate networks.
• ⚠️ After changing the settings, be sure to restart the interface with the command /interface wireless disable [find] && /interface wireless enable [find].

What to do if Wi-Fi doesn't work after changing the security type

Even with proper setup, problems can arise. Here are typical scenarios and their solutions:

Devices do not connect to the network

Reasons and solutions:

• 📱 Old gadgets (before 2012): not supported WPA3The solution is to return WPA2 or create a separate network for them.
• 🖥️ Windows 10/11: Update your Wi-Fi adapter driver via device Manager.
• 🍎 MacOS: manually add the network to System Preferences → Network, specifying the security type.
• 🤖 Android: Forget the network in the settings and reconnect.

The network is slow after changing the protocol

Possible reasons:

• 📉 Incompatible encryption: if the router is forced to use TKIP instead of AES, the speed drops by 30-40%. Check the settings.
• 🔄 Channel congestion: WPA3 may conflict with neighboring networks 2.4 GHzTry changing the channel to 1, 6 or 11.
• 📡 Weak signal: some devices (eg Wi-Fi 4) work worse with WPA3 at the edge of the coverage area.

The router constantly reboots

This is typical for older models (eg. TP-Link TL-WR841N) when trying to turn on WPA3Solutions:

• ⚡ Roll back the firmware to the previous version.
• 🔧 Reset your router to factory settings (button Reset for 10 seconds).
• 🔄 Use WPA2 instead of WPA3.

⚠️ Attention: If after changing the security type the router becomes unavailable (does not respond to 192.168.1.1), perform a hard reset. On most models, this requires:

1. Turn off the power.
2. Press and hold the button Reset (usually located in a hole).
3. Turn on the power by holding the button for 15-20 seconds.

After resetting, the router will return to factory settings (usually WPA2 with default password).

Additional security measures for Wi-Fi

Changing your security type is just the first step. To make your network truly secure, follow these recommendations:

1. Disable WPS

Protocol Wi-Fi Protected Setup (WPS) vulnerable to brute-force attacks. Even if your router supports WPA3, included WPS nullifies protection. How to disable:

• TP-Link: Advanced → System Tools → WPS → Disable.
• ASUS: Wireless → WPS → turn off.
• Keenetic: System → Components → uncheck WPS.

2. Enable MAC address filtering

This isn't a panacea (MAC addresses can be spoofed), but it does make it more difficult for attackers. The list of approved devices is configured in:

• D-Link: Wi-Fi → MAC Filtering.
• Netgear: Advanced → Wireless Settings → Access Control.

3. Set up a guest network

A guest network isolates your friends' devices from your main network. Optimal settings:

• 🔐 Security type: WPA2-PSK (AES).
• 🕒 Duration: Limit access (e.g. 4 hours).
• 📵 Disable local network access (AP Isolation).

4. Update your router firmware

Manufacturers regularly patch vulnerabilities. Check your firmware is up-to-date:

• TP-Link: Advanced → System Tools → Firmware Upgrade.
• ASUS: Administration → Firmware Upgrade.
• Keenetic: System → Firmware.

FAQ: Frequently asked questions about changing your Wi-Fi security type

Can I use WPA3 on an old router?

Depends on the model. Routers before 2018 (for example, TP-Link Archer C5) do not support WPA3 hardware. However, some models (for example, ASUS RT-AC68U) received support WPA3 After updating the firmware, check the specifications for your model on the manufacturer's website.

Why do some devices fail to connect after enabling WPA3?

Reasons:

1. The device was released before 2018 (for example, Samsung Galaxy S6 or iPhone 6).
2. The Wi-Fi adapter driver is out of date (applies to Windows PCs).
3. The router is in mixed mode. WPA2/WPA3, but the device is stuck on WPA2.

Solution: Create a separate network with WPA2 for problematic devices or update their software.

What password is considered strong for WPA3?

Minimum requirements:

• Length: 12+ characters (optimally - 16).
• Composition: upper and lower case letters, numbers, special characters (!@#$%).
• Exclude: dates of birth, names, dictionary words.

Example of a strong password: k7#pL9@mQ2$vR5!

Which is better: WPA3 or WPA2/WPA3 Transition Mode?

WPA3 preferable because:

• Eliminates vulnerabilities WPA2 (For example, KRACK).
• Uses a more secure hashing algorithm (SAE instead of PSK).
• Increases speed with optimized encryption.

Mixed mode (Transition Mode) is only needed if there are devices in the network that do not support WPA3.

Is it possible to hack a WPA3 network?

In theory, yes, but in practice, it's extremely difficult. Known vulnerabilities WPA3:

• Dragonblood (2019): Allows handshake interception, but requires physical access to the network.
• Downgrade attacks: An attacker can force the network into a standby mode. WPA2, if enabled Transition Mode.

For protection:

• Turn it off WPA2/WPA3 Transition Mode.
• Use complex passwords (see question above).
• Update your router firmware regularly.
