Yes, you can see which band a wireless client is using on a MikroTik device using various tools and settings available in RouterOS, MikroTik's operating system.

Here we explain how you can verify this information:

Using WinBox

1. Access WinBox: WinBox is a graphical tool that allows you to manage your MikroTik device. Connect to your MikroTik router using WinBox.
2. Go to “Wireless”: In the main menu, find and select the “Wireless” option. This will show you all the wireless interfaces on your device.
3. Verify interfaces and connected clients:
   • Within the “Interfaces” section, you will be able to see if the interface operates at 2.4 GHz or 5 GHz, which indicates the band it is using.
   • To view connected clients, click on the “Registration” tab within the “Wireless” section. Here you will be able to see all the clients that are currently connected to the network.
4. Customer details: By selecting a specific client in the list, you can view additional details about their connection, including the frequency band used. Look for fields like “Frequency,” “Rate,” and other parameters that tell you how the client is communicating with the router.

Using the Terminal

If you prefer to use the command line, you can access this information through the RouterOS terminal:

1. Access the terminal: You can use the terminal directly in WinBox or connect via SSH.
2. Use appropriate commands: You can use commands to list all clients connected to wireless interfaces. For example:bashCopy code/interface wireless registration-table print This command displays a list of all connected clients, the interface they are connected to, and specific details such as frequency, data rate type, and more.

Visual Verification on Network Map

In some cases, you can also use network visualization tools if they are configured to show how clients are connected, including which band they are using. This option depends on your specific network configuration and any network management software you may be using.

These tools and methods allow you to effectively monitor and manage the usage of frequency bands on your MikroTik wireless network, ensuring proper optimization and effective troubleshooting.
