Have you noticed that the internet is Rostelecom Is your Wi-Fi slowing down? Perhaps unauthorized devices—neighbors, guests, or even hackers—have connected to your Wi-Fi network. You don't need to be an IT professional to check the number of active connections and identify "unnecessary" devices. In this article, we'll look into 5 working methodsHow to count devices on your Wi-Fi, including official tools Rostelecom and third-party utilities.
It's important to understand that the simple number of connected devices is only half the information. More is needed. identify them (to distinguish your smartphone from someone else's laptop) and control access (For example, block unknown devices). We'll show you how to do this on routers. Sagemcom, Sercomm, Huawei and others that are most often issued by the provider.
If you've never accessed your router settings before, don't worry. We'll provide step-by-step instructions with images (for popular models) and explain all the technical terms. And at the end of the article, you'll find answers to frequently asked questions: what to do if there are too many devices on your network, how to limit connections, and why your router might display "unnecessary" devices.
1. Checking via the Rostelecom router web interface
The most reliable way is to log in router control panel via a browser. You don't need to install programs or connect cables (if you're already on a Wi-Fi network). All you need to know is Router IP address and login details.
Most routers have Rostelecom The control panel address is standard:
- 🌐
192.168.1.1— for models Sagemcom F@st 2804/3804/5364 - 🌐
192.168.0.1- For Sercomm RV6699 and some Huawei - 🌐
192.168.100.1- rare, but occurs in older devices
If none of the addresses open, check the sticker on the back of the router - it indicates the correct one. IP.

Instructions:
- Click
Win + R, entercmdand pressEnter. - Enter the command to view all devices on the local network:
arp -aA list will appear on the screen.
IPAndMAC addresses. - Now enter the command to view active connections to your router:
net view(you may be required to enter your router login/password).
- Compare
MAC addressesfrom the first list with those displayed in the router settings.
What does the data mean:
- 📌
IP address(For example,192.168.1.102) is a unique number for a device in your network. - 📌
MAC address(For example,00-1A-2B-3C-4D-5E) is the device’s “passport” that cannot be forged. - 📌
DynamicorStatic— type of appointmentIP(dynamic or static).
⚠️ Attention: Team arp -a shows all devices on the local network, including those connected via cable. To see only Wi-Fi clients, it's best to use specialized programs (see the next section).
A critical point: If your network uses technology Mesh (multiple access points), the command line may show duplicate devices. In this case, rely only on the data from the router control panel.
4. Third-party Wi-Fi monitoring programs
If the standard methods do not suit you, you can use specialized utilities for network analysis. They will not only show the number of connected devices but also provide additional information: traffic consumption rate, connection history, and even potential vulnerabilities.
Top 3 programs for Windows And Android:

- 🖥️
Advantages of third-party programs:
- ✅ Visible devices that may be hidden in the router's default settings.
- ✅ Show connection history (when the device was last online).
- ✅ They can block unknown gadgets directly from the interface (in Fing).
5. Checking through your personal account on the Rostelecom website
Not everyone knows, but in personal account on the website Rostelecom You can also view information about connected devices. However, its functionality is limited compared to the mobile app or the router's dashboard.
How to check:
- Go to the website
lk.rt.ruand log in. - Select a section
Services → Internet. - Find the block
My devicesorWi-Fi(depending on the personal account version). - There will be a list of devices that have connected to your network over the past 24 hours.
Limitations of this method:
- ❌ Doesn't always show current connection (there may be a delay of up to several hours).
- ❌ It is not possible to block a device directly from your personal account.
- ❌ Data about devices connected via cable may be missing.
⚠️ Attention: If you don't see a devices section in your personal account, your plan or router doesn't support this feature. In this case, use the other methods in this article.
But here you can:
- 🔄 Reboot your router remotely (if your internet connection is slow).
- 📊 View traffic consumption statistics (useful if someone is downloading large files).
- 🔒 Change your Wi-Fi password (section
Wi-Fi settings).
6. How to distinguish your device from someone else's?
You found an unknown device in the list—what should you do? Before blocking it, make sure it's not your device. Here's how to identify devices:
Method 1: By device name
- 📱 Smartphones and tablets are often listed under the model name (e.g.
iPhone-12-Pro,Xiaomi-Redmi-Note-10). - 💻 Laptops can have a username (eg.
Lenovo-PCorDell-7590). - 🎮 Game consoles are usually labeled as
PS5,Xbox-Series-Xetc.
Method 2: By MAC address
- First 6 characters
MAC addressesindicate the manufacturer. For example:- 🍎
A4:83:E7— Apple - 🤖
7C:11:BE— Xiaomi - 🪟
3C:D9:2B— Hewlett-Packard (HP)
- 🍎
- Check it out
MAC addressesyour devices:- On Windows:
ipconfig /allin the command line. - On Android:
Settings → About phone → General information → Wi-Fi MAC address. - On iPhone:
Settings → General → About → Wi-Fi Address.
- On Windows:
Method 3: By IP address
- Write it down
IP addressunknown device. - Enter in your browser
http://[IP address](For example,http://192.168.1.105). - If a web interface (for example, a camera or printer) opens, you will understand what kind of device it is.
How do you know if your device is jailbroken?
If a device with a non-standard name (for example, a set of random letters and numbers) or a MAC address from an unknown manufacturer appears on the network, or if it consumes a lot of bandwidth (this can be seen in programs like Fing), it is most likely a hacker. Another sign of a hack could be changing DNS servers in the router settings (check in the section Network → WAN).
7. What to do if an unknown device is found?
Have you discovered a gadget online that doesn't belong to you or anyone else in your household? Follow these steps:
Step 1: Check if you made any mistakes
- 🔄 Restart your router and check the list of devices again - it may have been a temporary glitch.
- 📱 Make sure it's not a guest's device (for example, a friend's smartphone that you had yesterday).
Step 2: Lock your device
- 🚫 Find the section in your router settings
Security → MAC Filtering. - 📝 Add
MAC addressunknown device to the blacklist. - 🔒 Save the settings and reboot the router.
Step 3: Strengthen Wi-Fi Security
- 🔑 Change your Wi-Fi password complex (at least 12 characters, with numbers and special characters).
- 🛡️ Turn on WPA3 instead of
WPA2(if the router supports it). - 🔄 Turn it off
WPS(This is a vulnerable protocol that can be easily hacked). - 📡 Hide network name (
SSID) in the settings (but this is not a panacea - experienced hackers will find it even hidden).
Step 4: Check your router for viruses
- 🦠 Some malware can connect to your network through vulnerabilities in your router firmware.
- 🔄 Update your router firmware to the latest version (section
System → Software Update). - 🛡️ Install antivirus software on all your devices and scan them.
8. Common Mistakes and Myths About Connected Devices
When checking devices on a Wi-Fi network, many users encounter misunderstandings or misconceptions. Let's look at the most common ones:
Myth 1: "If there are 10 devices on the network, and I only have 5, then I've been hacked."
In fact, the router can show:
- 📡 Devices connected via cable (eg. Smart TV or game console).
- 🔄 Devices that were previously connected but have not yet been disconnected (for example, a smartphone in sleep mode).
- 🤖 Smart gadgets (lamps, sockets, vacuum cleaners) that you forgot to take into account.
Myth 2: "Hiding the SSID will protect my network."
Hiding the network name (SSID) doesn't make it any safer. Experienced hackers can easily find it using specialized software. It's better to configure it strong encryption (WPA3) And complex password.
Myth 3: "If you limit the number of devices in your router settings, strangers won't be able to connect."
Limiting the number of connections (e.g., "maximum 10 devices") doesn't block hackers. They can disable one of your devices to make room for theirs. It's better to use MAC address filtering.
Error 1: Ignoring devices with "strange" names
If a device with a name like this appears on the network android_123456 or host-789, don't write it off as a glitch. It could be:
- 📱 Smartphone with an automatically generated name.
- 🤖 A smart speaker or other gadget that connected without your knowledge.
- 🕵️ A hacker disguised as a legitimate device.
It's better to be on the safe side and block it for a while to check if your gadgets' internet connection will be lost.
Mistake 2: Using default passwords
Many people leave the default Wi-Fi password (for example, 12345678 or password). Such networks are hacked in a few minutes. Always be creative. unique password With:
- 🔢 Numbers and letters in different upper and lower case.
- 🔤 Special characters (
!@#$%). - 📏 At least 12 characters long.
FAQ: Answers to Frequently Asked Questions
Is it possible to find out which websites connected devices visit?
No, the router doesn't store your browsing history. However, you can:
- 📊 View traffic statistics by device (some routers have this function).
