Do you want to know if somebody in your neighbor is connected to your wireless network without your permission? Your internet connection is very slow and you suspect that someone is stealing or hacking your WiFi?
Yesterday, we faced this same problem of slow internet speed, we can hardly surf anything. When we contacted our operator, he informed us that we are overload on our data consumption. He advised us to change the WiFi password as maybe someone stealing our WiFi. We changed the password and our internet speed becomes normal. This means that there is some intruder out there, stealing our WiFi.
Changing passwords are not the ultimate solution. Because every time, we will change it, that Mr. Thief will somehow manage to find it. There are other dangers also. I was afraid that he may have access to our personal data? He may intrude into our network, steal our data and trace our transactions from any computer device that we use on the same network. He may monitor the websites we are opening, or can trace the credit card and bank account numbers we are using for online purchase and in future may use it for himself.
How to find out if somebody is stealing or hacking your WiFi?
I researched and find that there are plenty of Android network apps on Google Play Store which will help us to catch a WiFi stealer. Our Android phone will help us in keeping an eye on our home or office network through these network monitoring apps. We can also make sure nobody else is accessing our WiFi. These android apps will help us in protecting our network from intruders.
So, here is the list of Android Apps to Detect WiFi Thieves and Block them away from your network to protect your data.
Fing – Network Tools
Fing is a super-fast network analysis App which will allow us in finding out all the devices connected to our WiFi network. Fing WiFi Security App helps us to evaluate security levels, detect intruders and resolve network issues.
Through Fing, we can search any device on a network by IP, MAC, Name, Vendor, and Notes and we will be able to see the history of all discovered networks. This the easy solution to finding out if any new devices added to our network. Fing can find hundreds of open ports in a few seconds and ping and trace route which helps in understanding the network performances. This Android Network tool allows us to even troubleshoot network problems and also to achieve best network performance.
Together with its add-on Fingbox hardware, we can enhance the network tools functionality. Additionally, this can also block and pause the network connections. Furthermore, bandwidth and the Wi-Fi sweet spot can be accurately monitored.

This Network Discovery app will help us in discovering hosts and scanning their ports on our Wifi network. This app can be used as a TCP Port Scanner, check in NIC vendor database and the service detection according to the service banner. This Android network discovery app can connect to known services (HTTP, ssh, telnet) directly from the application results and do the scan in an adaptive scanning rate (slow start, then adaptive to network latency). Network discovery insists the users download the databases for the NIC list which comes in about 500 KB.

Net Scan doesn’t include any other tools, but for a quick network and port scan, this app is hard to beat. Net Scan is free, doesn’t have any ads, and the only in-app purchase is for donations to the developer.
Network Scanner allows us to scan IP allocation and opened a port in our local area network. It can verify suspicious vulnerabilities or security issues within the network and can assist in understanding the use of our network.
With the help of this app, we can monitor our network and see who else is connected to our network and what is going on. The analyzed reports are generated and can be exported to general formats.

Wifi Inspector is a simple tool to see all the devices connected to our network, giving relevant data such as IP address, manufacturer, device name and Mac Address. The list will include both wired and wireless devices connected to our network. Wifi Inspector also allows us to save a list of known devices with custom name and this makes it easier for us and we will not need to go checking the data whenever we make a scan. It can find intruders in less than 30 seconds and will alert us if a new device joined in the network so that we can always be alert to any presence of a new intruder into our network. It still lacks the ability to terminate the connections at will.

I am using this app myself to catch the WiFi Intruder. This app displays the connected devices, WiFi signal info, speed, etc. When somebody intruded into our network, then this app will display intruders IP addresses, MAC addresses, Vendor names, Wireless access points (WAP, AP) and we can also Ping to the device, Scan the Port and even Block user from our WiFi. This Android WiFi analyzer app can tell us the bandwidth speed, Encryption, Frequency to understand the best usage scenarios and performance boosts. MAC address, DHCP, and DHCP lease are also analyzed. Additionally, there are Access point tabs and Connection tabs showing the Access point details from the SSID specified network and the active connections in the system respectively. Blacklist IP Address feature helps us to remove the specified connections and block the specific IP address.
