How to identify and label devices on your network
To identify the devices on your network, you can use the Device Information and Network Adapter Company columns. These columns can give you clues about the type and brand of the devices. For example, if you see a device with "Apple" as the network adapter company, it is likely an iPhone, iPad, or Mac. If you see a device with "Samsung" as the network adapter company, it is likely a Galaxy phone or tablet.
You can also use the Device Name column, but this may not be very reliable, as some devices may have generic or default names. For example, you may see a device named "DESKTOP-123456" or "Android-abcdef". You can try to change the name of your own devices to make them more recognizable.
To label the devices on your network, you can use the right-click menu and select "Properties". This will open a window where you can enter a custom name and description for the device. You can also choose a color and icon for the device. This will help you distinguish the devices that belong to you from the ones that don't.

How to block unwanted devices from your network
To block unwanted devices from your network, you need to access your router's settings and use its MAC filtering feature. MAC filtering is a method of allowing or denying access to your network based on the MAC address of the device. The MAC address is a unique identifier that every device has.
To access your router's settings, you need to know its IP address and login credentials. You can usually find these on a sticker on your router or in its manual. You can also try to use the default values, which are often "admin" for both username and password.
Once you access your router's settings, look for the MAC filtering option. It may be under different names depending on your router model, such as "Wireless MAC Filter", "Access Control", or "MAC Address Filtering". Enable this option and choose whether you want to allow or deny access to the devices on your list. Then, enter the MAC addresses of the devices that you want to block or allow. Save your changes and restart your router.
