To find hidden devices on your Wi-Fi, log into your router's admin page to check the connected device list (DHCP client list) or use a network scanner app like Fing to identify unknown gadgets by their IP/MAC addresses, then investigate unfamiliar entries by turning devices off to see which one disappears. You can also use command prompt commands like ipconfig and arp -a for IP/MAC details or search the manufacturer ID from the MAC address online.
The easiest way to see what's connected to your network is through your router's web interface:
Access your router's admin page via a web browser, usually by typing in the router's IP address. Log in with the admin credentials, which you can find in the router's manual or on the device itself if you haven't changed them. Look for a section like Attached Devices, Device List, or DHCP Client List.
The easiest way to check who is using your WiFi is by using a network scanning tool like Fing. Fing is the #1 network scanner that quickly identifies all devices connected to your WiFi, whether you're using a mobile device or a desktop.
Network administrators can employ various methods and tools to identify these unauthorized endpoints:
The easiest way to check what devices are using your Wi-Fi is to access your router's admin panel and inspect the list of connected devices, typically available in a section called "Connected Devices," "Attached Devices," or "DHCP Client List." If you notice a device that you don't recognize, it could be a hacker.

How to Find Unauthorized Devices on Your Network
What Are the Most Common Ways to Discover Devices on Your Network?
You can detect a hidden camera by using a flashlight, smartphone camera, RF detector, or Wi-Fi scanner app. Look for reflections from lenses, suspicious objects facing private areas, or unknown devices connected to local networks. Each method offers a different layer of detection.
Log in to the router.
This will take you to the Mac-Filtering page. Under 'Configure MAC Filtering below:', click on the drop-down menu and select the option that best suits your requirements. “Turn MAC Filtering ON and DENY computers listed to access the network”.
A hidden network is generally defined as one that is not broadcasting its SSID. If you are seeing that name displayed in your wi-fi list, it is very possible that the wi-fi administrator has jokingly named their network that name.
Signs your router or internet might be hacked
Fing is the #1 Network Scanner: discovers all the devices connected to your WiFi and identifies them, with our patented technology used also by router manufacturers and antivirus companies worldwide.
Routers that deliver beyond Wi-Fi®
To extend this experience into homes and businesses, Vantiva designs routers that meet the demands of higher speeds, more connected devices, advancing Wi-Fi® standards, one-click mesh integration and management, and enhanced network security.
If your network is unsecured or if your neighbors have your password, they can use your WiFi without permission. To avoid unauthorized access, make sure to use WPA3 encryption and use a strong, unique password.
Look at the IP addresses.
The IP addresses that start with the same numbers as your router's IP address (i.e., 192.168) are connected to your router. This shows the IP address and MAC address of each connected device. Every device that connects to the internet has a unique MAC address.
Encrypt your network.
To encrypt your network, simply update your router settings to either WPA3 Personal or WPA2 Personal. WPA3 is the newer — and best — encryption available, but both will work to scramble your information.
Change Wi-Fi Password: Since you're seeing unknown devices, it might be worth changing your Wi-Fi password again to ensure no one outside your intended network has access. Enable WPA3 Security: Make sure your router is set to use the highest level of security available (WPA3 if possible).
Method 1: Using your Router's Admin Page (Most Effective)
Can I disable an unknown device? Yes, you can disable an unknown device, especially if it's causing issues. In the device manager, right-click on the device, and select "Disable." This won't uninstall it; it just stops it from functioning. Keep in mind that this is a temporary solution.
Solid Objects Can Block Wireless Signals
So, by surrounding your router will walls and a door by putting it into a closet, you're basically making the signal weaker and decreasing the strength and reliability of your wireless network.
