Who's Connected to My Wi-Fi: 10 Best Network Analysis Software for 2026

Have you noticed that your internet has become slower and your data is running out suspiciously quickly? Perhaps your Wi-Fi Unauthorized devices connected—neighbors, guests who forgot to disconnect, or even hackers exploiting router vulnerabilities. In 2026, the problem of "parasitic" connections became even more pressing: modern gadgets automatically save networks, and many users still use standard passwords like admin/admin or 12345678.

In this article we will look at 10 proven programs for Windows, macOS, Android and iOS, which will show, who exactly is on your networkHow much traffic each device consumes, and how to block it. You'll learn which tools are suitable for in-depth analysis (even identifying a smartphone model by MAC address), and which ones will handle basic tasks in two clicks. We'll focus on legal methods—those that don't involve hacking other people's devices or violating the Law on Personal Data.

Why is it important to control connected devices?

According to data Kaspersky Lab for 2026, 37% of home Wi-Fi networks in Russia have at least one unauthorized connection.Reasons range from the harmless (a neighbor accidentally connecting to your network with a similar name) to the dangerous (an attacker using your IP for attacks or spreading viruses). Here are the key risks:

• 🐢 Internet speed dropEach additional device eats up some of your bandwidth. This is especially noticeable when playing online games or streaming 4K video.
• 💸 Traffic overuseIf you have a limited data plan, third-party devices can use it up within a few days (this applies to mobile internet via a router).
• 🔓 Data leak: Files containing viruses or phishing links may be transmitted through your network, which will put all connected gadgets at risk.
• 🕵️ Legal liability: If illegal actions (for example, a DDoS attack) are committed from your IP, it will be difficult to prove your innocence.

Many users mistakenly believe that simply changing their Wi-Fi password is enough. However, experienced "freeloaders" can:

• 🔄 Reconnect if you are using the same one SSID (network name) and a weak password.
• 📡 Intercept traffic through protocol vulnerabilities WPA2 (for example, attack KRACK).
• 🖥️ Gain access to local resources (printers, network drives) if they are configured incorrectly.

⚠️ Attention: If you find a device on the network with a MAC address starting with 00:0C:29 or 00:50:C2, it could be a virtual machine or emulator. Such addresses are often used to disguise real devices.

Top 5 programs for Windows and macOS

Desktop utilities offer the widest range of functionality, from network scanning to deep traffic analysis. We've selected tools that work on modern operating systems (including Windows 11 24H2 And macOS Sonoma) and do not require root rights.

WireShark — is a "Swiss Army knife" for network analysis, but it's complex for beginners. If you need a simple utility, consider GlassWire: It displays all connected devices on an interactive map and also tracks which programs on your PC are consuming bandwidth. For example, you might find that svchost.exe secretly sends data to an external server.

Suitable for blocking devices NetCut, but be careful: improper use of ARP spoofing can disrupt the entire network. It's best to first try the router's standard tools (we'll discuss them below).

Mobile applications for Android and iOS

Smartphones have become the primary tool for Wi-Fi testing, especially when you need to quickly check the network at a party or in a cafe. The main advantage of mobile apps is that they run without installation and often have an intuitive interface.

For Android The best are considered to be:

• 📱 Fing — identifies devices based on the manufacturers’ database and shows open ports.
• 🛡️ NetX — analyzes network security, searches for router vulnerabilities.
• 🔍 WiFi Thief Detector — specializes in finding "freeloaders" with real-time notifications.

On iOS The selection is more limited due to Apple's restrictions, but these apps get the job done:

• 🍎 Network Analyzer — scans the local network, shows MAC addresses and vendors.
• 📊 IP Scanner — simple interface, export of reports to PDF.

⚠️ AttentioniOS apps can't block devices from the network—this is a limitation of the operating system itself. The most they can do is scan and notify.

It stands apart Fing — its MAC address database is updated weekly, so it identifies device models more accurately than others. For example, instead of an abstract "Samsung," it might show Samsung Galaxy S23 Ultra (SM-S918B)This helps you distinguish your smartphone from someone else's with the same name.

How to use your router's built-in tools

Not everyone knows that most modern routers (from TP-Link, ASUS, Keenetic and others) have built-in tools for monitoring connected devices. This is the most reliable method, as it doesn't rely on third-party software and displays up-to-date information in real time.

To see the list of devices:

1. Open your browser and enter the router's IP address (usually 192.168.0.1 or 192.168.1.1).
2. Log in (default logins: admin/admin, admin/password, or see the sticker on the router).
3. Go to a section like DHCP Clients, Connected Devices or Local area network.

Here's what it looks like on popular models:

In these menus you will see:

• 🖧 IP address And MAC address devices.
• 📱 Host name (if the device broadcasts it, for example, iPhone-12-Pro).
• ⏱️ Connection time and consumed traffic (on some routers).

To lock your device:

1. Find it in the list and click Block or Block.
2. Add the MAC address to the blacklist (section MAC Filtering or Access control).
3. Update your router firmware—new versions often fix vulnerabilities that allow you to bypass blocking.

⚠️ AttentionIf your device continues to appear online after being blocked, check your settings. DHCP ReservationIt may be assigned a static IP, which bypasses the restrictions.

What should I do if my router doesn't show all my devices?

Sometimes routers hide devices connected through WPS or guest network. Try:

1. Disable the guest network in the settings.

2. Temporarily turn off AP Isolation (if enabled).

3. Use third-party scanning programs (for example, nmap in Linux).

How to identify an "intruder": signs of suspicious devices

Not all devices on your network are necessarily malicious. These could include:

• 📺 Smart TVs (Samsung, LG, Sony) - often connect automatically.
• 🎮 Game consoles (PlayStation, Xbox) - may be displayed under non-obvious names.
• 🔌 IoT gadgets (Xiaomi lamps, robot vacuum cleaners) - sometimes have the manufacturer's MAC address, but do not broadcast the name.

However, these signs should be a warning sign:

• 🕵️ Unknown manufacturer: MAC address starts with 00:0E:35 (Sonos), but you don't have devices of this brand.
• ⚡ High traffic: The device is consuming >100 Mbps in the background (possible data leakage or mining).
• 🌍 Connection at unusual times: activity at night when everyone is sleeping.
• 🔄 Frequent MAC address changes: a sign of using tools to bypass blocking (for example, MacChanger).

To accurately identify your device:

1. Check it out IP address in the router list.
2. Enter in your browser http://[IP address] — some gadgets (printers, NAS) have a web interface.
3. Use the command ping [IP address] in the terminal, and then arp -ato confirm the MAC.

If the device is suspicious, but you are not sure, turn it off for a day and observe:

• 📈 Has your internet speed increased?
• 📵 Have you stopped receiving complaints from your provider about traffic overages?
• 🔒 Have any strange activities (such as unauthorized account logins) disappeared?

What to do if you find a foreign gadget

Found an unfamiliar device on the network? Follow these steps:

1. Step 1: Blocking
   • Block the MAC address in the router settings (section MAC Filtering).
   • If your router doesn't support blocking, change your Wi-Fi password to a complex one (at least 12 characters, with numbers and special characters).
2. Step 2: Security Check
   • Update your router firmware to the latest version (fixes vulnerabilities like Dirty Cow or VPNFilter).
   • Turn it off WPS And UPnP - These protocols are often exploited by hackers.
   • Turn on Firewall on the router (if there is such an option).

Step 3. Monitoring

• Install a program to monitor new connections (for example, GlassWire with notification option).
• Set up your router to send email notifications when new devices appear (available in ASUS And Keenetic).

If the suspicious device appears again:

• 🔄 Reset your router to factory settings (button Reset on the back panel).
• 🔒 Change the network name (SSID) - some viruses remember it and connect automatically.
• 📡 Enable hidden network mode (turn off the broadcast SSID), but keep in mind: this is not protection, but just a slight complication for beginners.

⚠️ AttentionIf, after all these steps, the foreign device still appears, your router may be compromised at the firmware level. In this case, it is recommended to replace it with a model that supports it. OpenWRT (For example, GL.iNet), which allows you to flexibly configure security.

Common mistakes and how to avoid them

Many users make critical errors when checking the network, which ruin all their efforts. Here's what it is forbidden do:

• 🔄 Use default passwords: even if you changed the Wi-Fi password, but left the default logins for logging into the router (admin/admin), the attacker can reset the settings and connect again.
• 📵 Ignore guest networkIf it's enabled but not in use, disable it. This is a separate connection channel that's often overlooked.
• 🕳️ Rely entirely on MAC filtering: MAC addresses are easy to spoof (for example, using Technitium MAC Address Changer).
• 📡 Disable encryption: some "advisers" recommend using Open Network (without password) with MAC filtering. This is dangerous—the traffic will be transmitted in cleartext.

Common Wi-Fi security myths:

• 🚫 Hidden SSID protects against hacking: in fact, the network name is easily determined by packet analyzers like Wireshark.
• 🚫 "WEP encryption is better than nothing.": WEP It can be hacked in minutes even on a smartphone using Wifi WPS WPA Tester.
• 🚫 "If the internet is fast, then there are no other devices.": Modern viruses can run in the background without loading the network.

The right approach to security:

1. Use WPA3-Personal (or WPA2-AES, if WPA3 is not supported).
2. Turn on 802.11w Protected Management Frames (protection against deauthentication).
3. Check the list of devices regularly (once every 1-2 weeks).
4. For critical data (for example, work with a bank) use VPN even at home.

FAQ: Frequently asked questions about checking your Wi-Fi network

Is it possible to find out who exactly is using my Wi-Fi (name, address)?

No, you can only determine the device model and manufacturer using the MAC address or IP (for example, Apple iPhone 15 Pro). To identify a user, data from the provider is required, and this data is only released upon request by law enforcement. If you suspect illegal activity, contact the police with the router logs.

The program shows my device as "unknown." Why?

This happens if:

• The device does not broadcast its name (for example, some IoT gadgets).
• The MAC address is spoofed (common in hacker tools).
• The program database is out of date (update it or use an online service like MAC Vendors).

To confirm that this is your device, check its MAC address in the gadget settings (for example, in Settings → About phone → Status on Android).

Is it possible to block a device permanently?

There is no absolutely foolproof way, but a combination of these measures will make the task as difficult as possible:

1. Add the MAC address to the router's blacklist.
2. Change your Wi-Fi password to a complex one (for example, k7#pL9!vQ2$mN4*).
3. Turn on MAC Address Cloning Protection (available in routers) ASUS).
4. Set up Static DHCP Lease only for your devices.

If an attacker still manages to penetrate your network, consider replacing your router with a model that supports it. IPS/IDS (For example, Firewalla or Ubiquiti Unifi).

Is it legal to scan other people's devices on my network?

Yes, you have the right to analyze traffic in his own networks, but with reservations:

• 🔍 Allowed: scan connected devices, block them, change your router settings.
• ❌ It is prohibited to: intercept traffic (for example, through Wireshark) for the purpose of obtaining personal data (passwords, messages). This violates Federal Law No. 152 "On Personal Data" and may be classified as unauthorized access (Article 272 of the Criminal Code of the Russian Federation).

If in doubt, consult a lawyer. For legal monitoring, information about MAC addresses and traffic consumption is sufficient.

Why does the router show devices that are not in the house?

Possible reasons:

• 📶 Neighboring networks with the same name: if you and your neighbor have the same SSID (For example, TP-Link_1234), devices can "jump" between networks.
• 🖥️ Virtual machines: some programs (for example, VirtualBox) create virtual network adapters.
• 🔄 DHCP cache: The router may store data about devices that have been disconnected for a long time. Restart it.
• 📡 Mesh systems: If you have multiple access points (eg. Google Nest WiFi), they can be displayed as separate devices.
