Unknown Device on Network: Learn How To Identify and Remove It

You may be able to see the unknown device on network connection of your phone or router along with the usernames of the networks.

Unknown Device on Network

More information on the unknown devices can be checked by tracing their MAC IDs. Your device also detects the SSIDs of other nearby devices.

Keep reading this article for more details!

Why Is the Unknown Device on Network Seen on the System?

The reason you may find strange devices on the network manager is that your Wi-Fi is using WPA Protocol. Your device will continuously try its attempts, even when connected already, to find a new network with better connections. Therefore, if you’re close to an internet connection, your device will show the stranger’s network on the network manager.

Once the devices are nearby, they send a “packet” of data consisting of device information that other devices recognize and respond to, by sending the same signals back from your device. These signals enable users to securely connect their devices to each other’s networks. These signals contain MAC and IP addresses. This is done to show the owner of the device that there is SSID “username” available but is secured.

How to Identify Devices Connected to Your Network?

On the screen, you can see the names of the networks. If any network names look unknown to you, you can remove them from your device or block them permanently from your phone/router. If you’re not sure how to identify the Wi-Fi network, check the following steps.

– Note the Device Mac Address To Identify the Unknown Device on Network

MAC address and IP address are saved once the device is connected safely to your network. Therefore, go to your phone or computer’s settings and then Wi-Fi settings, there you’ll find the MAC Address. Once you trace the MAC ID of the unknown network, you’ll know the location, time, and hours it has consumed your internet as well as the device name and manufacturer information.

– Check if It Matches the Network Address of Your Known Users

Check the list of MAC and IP addresses and see if any address is unknown. Remove that specific unknown network from your device. Once you know the unknown network you just have to go to the settings and force stop that particular network device and do a right-click on the network name to pop up options. Click on Block to block the network from your device.

Stop Strange Devices From Connecting to Your Network

Mostly, your device has a Wi-Fi-protected setup due to which a stranger device is only shown to you but it isn’t connected to your network device. To prevent a strange network from connecting to your device, you can download the Home Network Security app. You can do the following things to prevent the connection as well.

Stop Strange Devices From Connecting

5. How To Find a Rogue Access Point?

Enabling rogue access point detection on the wireless Firebox helps the wireless radio in the device to scan the wireless channels to identify the unknown wireless access points on your device. You can also configure the scan to run continuously or you can set time intervals for the scan.

6. Why Are Unknown Cell Phones Shown up on My Network?

It is not an unknown cell phone but a Wi-Fi signal that shows on your network. What you see on the screen is the nearby phones that have their mobile data/ Wi-Fi turned on and your phone is catching their signals, trying to connect to them. You’ll get the signals of the unknown networks every time they’re within the range of your router.

7. How to Block a Device From WiFi Connection?

It depends on the type of router you are using. However, the majority of the routers have options to add a device to the blocklist under the “Device management” section of the access point control panel. There you will see the “block user” button. Press that and the user you want to block from your connection will be blocked and removed. They will no longer be able to use your Wi-Fi network connection nor will you see their device on your screen.

8. How Can You Tell if Someone Is Using Your WiFi?

The advanced wireless routers now have indicator lights that show Internet connectivity, wired network connectivity as well as wireless connectivity. To check if someone is using your network, turn all the devices’ Wi-Fi off and unplug any plugged network connectivity and then observe the signal light on your wireless router. If the light does not stop flickering, it means someone else from the outside is using your Wi-Fi.

9. Can Devices Get Identified by Their Mac ID Address?

When a strange device is connected to your network the device collects the data of the stranger network and saves it in its history. That data contains MAC ID addresses and other information. That address can be used to identify the maker and model of the device, even when the device isn’t in our accessibility.

Can Devices Get Identified by Their Mac ID Address

This is known as OUI, Organizationally Unique Identifier. It shows if the device that is connected to your network is a mobile, laptop or PC etc.
