Changing your wireless network password is one of the first steps you should take after installing new equipment or if you suspect a password leak. The network owner MikroTik It's important to understand that default security settings are often insufficient to protect traffic in today's environment. While updating credentials doesn't require extensive programming knowledge, it's critical to preventing unauthorized access to local resources.
Management interfaces for routers of this brand, such as WinBox or WebFig, provide flexible tools for security configuration. Traffic encryption This becomes a barrier to potential attackers attempting to intercept transmitted data. In this article, we'll detail a process that will allow you to quickly update access keys and select the optimal security protocol.
Preparing to change security settings
Before making any changes to your router's configuration, ensure the connection is stable. If you plan to change wireless network settings, it's best to perform these actions from a device connected via cable connectionThis will eliminate the risk of connection loss when the new settings are applied and the router reboots the radio module.
Make sure you have up-to-date login information for the administration system. By default for devices MikroTik login is used admin Without a password, unless you've changed it previously. However, relying on the absence of a password in 2026 is absolutely unacceptable.
⚠️ Attention: If you change the password while connected to the WiFi network you're setting up, the connection will be disconnected immediately after the settings are applied. You'll have to reconnect to the network with the new key.
It is also worth checking the version of the installed operating system. RouterOSIn older interface versions, the layout of some menu items may differ from the latest builds. The interface is constantly being improved, and new security features are being added.
Login to the WinBox and WebFig control panel
To make changes to your wireless network configuration, you'll need access to the graphical interface. The most popular tool among administrators remains the utility WinBoxIt provides a direct connection to the device even without a configured IP address, operating at the MAC address level.
Launch the program and find your device in the neighbors list. After entering your credentials, click the button ConnectIf you are using a browser, enter the router's IP address (usually 192.168.88.1) in the address bar. Interface WebFig will open in a new tab, providing similar functionality.
It's important to differentiate access rights. To change the WiFi password, user and group rights are sufficient. read/writeFull rights full These are only required for kernel system changes or removing critical services. Do not use an account with full privileges for everyday tasks unless necessary.
- 🔹 Run the utility
WinBoxon a computer with Windows or macOS. - 🔹 Enter the IP address or select the device from the discovery list.
- 🔹 Log in using your login
adminand the current password. - 🔹 When logging in through a browser, make sure the connection is secured using the HTTPS protocol.
Setting up the Wireless Interface
After successful authorization, go to the wireless network management section. Select "Wireless Networks" from the menu on the left. Wireless. This displays all available radio modules of your device. Depending on the router model, this may be wlan1, wifi1 or cap1.
Double-click the desired interface to open its properties window. We are interested in the tab Wireless, where the main operating parameters of the radio module are located. This is where the network name (SSID) and operating mode are set.
Pay attention to the field ModeTo create an access point it must be set to ap bridgeIf client or monitor mode is selected here, WiFi sharing is not possible. Make sure the checkbox is checked. Disabled is not active, otherwise the interface will be disabled.
| Parameter | Recommended value | Description |
|---|---|---|
| Mode | ap bridge | Access point mode |
| Frequency | auto or 2412-2472 | Frequency range (2.4 GHz) |
| Band | 2GHz-b/g/n | Data transmission standard |
| Channel Width | 20/40mhz Ce | Channel width for speed |
What to do if the interface does not turn on?
If the indicator doesn't light after turning on the interface, check whether the radio module is blocked by country settings. Some regions have power and channel restrictions.
Configuration of security and encryption protocols
The key step is choosing a protection method. Go to the tab Security Profile in the wireless interface settings window. Here you will see a drop-down list Security Profile. The default profile is often used default, but it's better to create a new one or edit an existing one for precise control.
In the security profile settings window that opens, find the field Authentication TypesFor maximum compatibility and security in today's environment, you should choose WPA2 PSK or WPA3 PSK, if all your devices support the new standard. Obsolete protocol WEP Use is strictly prohibited.
In the field Unicast Keys And Group Key Update You can set encryption key refresh intervals. This improves security by forcing devices to constantly change session keys, making it more difficult to intercept traffic using cryptanalysis.
⚠️ Attention: When choosing WPA3 Old devices (such as printers or old smartphones) may no longer see or connect to the network.
Directly in the field Pre-Shared Key A new password is entered. The key must be at least 8 characters long, but for security, it is recommended to use strings of 12-16 characters containing numbers and special characters.
☑️ Check security settings
Managing security profiles
In the operating system RouterOS Security profiles can be shared across all interfaces or customized. This allows you to create guest networks with separate passwords without affecting the main infrastructure. Profile management is performed via the menu. Wireless -> Security Profiles.
Here you can create multiple entries. For example, a profile Home_Secure for personal devices with a complex password and Guest_Open (with limitations) for visitors. When linking a profile to the interface in the settings Security Profile the created entry is selected.
If you use the same profile for both 2.4 GHz and 5 GHz bands, the password will change on both frequencies at once.
- 🔹 Open the menu
Wirelessand go to the tabSecurity Profiles. - 🔹 Click the button

Applying settings and checking the result
After entering a new password and selecting the encryption protocol, click the button OK or ApplyThe system will apply the changes and the radio module will restart. This process takes a few seconds. In the system logs (Log) a message about restarting the interface may appear wlan1.
Now you need to test the result. Take your smartphone or laptop, find your name (SSID) in the list of available networks, and try connecting. The device will request a new access key. Entering the old key will result in an authorization error.
If the connection is successful, check your internet speed and connection stability. Sometimes, when changing the protocol, WPA on WPA2/3 Devices may require you to "forget" the network before reconnecting to ensure encryption settings are updated correctly.
⚠️ Attention: Interfaces and item names may differ slightly depending on the version. RouterOSAlways check the official MikroTik documentation for your software version.
It is also recommended to check the list of connected clients via the menu Wireless -> tab RegistrationThis displays all devices currently using your network. Unknown MAC addresses may indicate a compromised key.
Where can I view connection logs?
Logs are available in the System -> Log menu. Filter entries by the word "wireless" or "ppp" to see authentication attempts and the reasons for access denials.
Is it possible to change the password via the mobile app?
Yes, MikroTik has released an app. WaveConnect And MikroTik for Android and iOS. They allow you to perform basic settings, including changing your WiFi password, via Bluetooth or a local network. However, the apps' functionality is limited compared to the full version. WinBox.
What should I do if I forgot my router password?
If you've lost access to the admin panel, you'll need to perform a factory reset. There's a reset button on the router. Reset. Press and hold it while the power is on until the indicator starts flashing. USRAfter this, the device will be reset to factory settings, including a blank administrator password.
Should I change my password regularly?
From a modern cryptographic perspective, frequent password changes (e.g., once a month) don't provide a significant advantage if a strong key and the WPA2/3 protocol are used. It's much more important to keep your router firmware up to date and disable unnecessary services, such as WPS or remote access.
Why doesn't the TV connect after changing the password?
Older Smart TVs often don't support new encryption standards or have issues caching network settings. Try selecting the "Forget Network" option in your TV settings and reconnecting. If the issue persists, check if the security mode is set to "Only." WPA3, which may not be compatible with legacy devices.
