How to check who is connected to a Rostelecom Wi-Fi router: all the methods

Have you noticed your internet is slower than usual, or do you suspect someone is accessing your Wi-Fi? Router owners Rostelecom This problem is common, especially if the network password is simple or has been accidentally disclosed. Fortunately, there are several ways to check the list of connected devices: through the router's web interface, a mobile app, specialized programs, or even the command line.

In this article we will look at all current methods for router models Sagemcom [Fast] 5364, 5366, 5370, Sercomm RV6699, ZTE H298A and others that it provides RostelecomYou'll learn not only how to view current connections, but also how to block unknown devices, change passwords, and set up MAC address filtering. And if you rent equipment from a provider, we'll also advise you on how to stay within your contract.

Important: Some settings may vary depending on firmware versions router. If your model isn't mentioned in this article, the testing principles remain the same—only the menu item names will differ.

1. Checking via the Rostelecom router web interface

The most reliable way is to access the router's control panel through a browser. This doesn't require installing any additional software, and data is updated in real time.

Instructions for most models:

1. Connect to Wi-Fi your router (or use an Ethernet cable).
2. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1If these addresses don't work, check the sticker on the back of the router - it may indicate a different IP (for example, 192.168.100.1 for some models ZTE).
3. Enter your login and password. By default, this is often admin/admin or user/userIf you changed them, use your data. On models Sagemcom the password can be indicated on the sticker (field Password or Wi-Fi Key).
4. Go to the section with the list of devices. The path depends on the model:
   • 🔹 Sagemcom Fast 536x/537x: Status → Local Network → DHCP Clients or Wireless Network → Statistics
   • 🔹 Sercomm RV6699: Network → LAN → DHCP Clients List
   • 🔹 ZTE H298A: Network → WLAN → Associated Devices

In the table you will see:

• 📱 Device name (if it transmits it, for example, iPhone-12-Pro or Xiaomi-11T).
• 🔢 MAC address — unique identifier (example: 00:1A:2B:3C:4D:5E).
• 📡 IP address in a local network (for example, 192.168.1.103).
• ⏱️ Connection time (not on all models).

Check your connection to your router (Wi-Fi or cable) | Disable VPN/proxy in your browser | Try a different browser (Chrome, Firefox, Edge) | Reset the router using the Reset button (hold for 10 seconds) -->

If you see unfamiliar devices in the list, you can block them directly in this section (usually there is a button Block or Block). On models Sagemcom You can also use the section for this Wireless Network → MAC Filter.

⚠️ Attention: If you rent a router from RostelecomBlocking devices via a MAC filter can lead to problems with technical support. ISPs sometimes use remote connections for diagnostics, so blocking their equipment can cause configuration issues.

2. Using the Rostelecom Personal Account mobile application

If you prefer to control your router from your smartphone, install the official app. Rostelecom Personal Account (available for Android And iOS). It allows you to not only check connected devices but also change the Wi-Fi password, reboot the router, or enable a guest network.

Step-by-step instructions:

1. Download and install the application from Google Play or App Store.
2. Log in using your personal account login Rostelecom (phone/email + password).
3. Go to the section Services → Internet → My Devices (the name may differ in new versions of the application).
4. Click on your router - a list of connected devices will open, showing their names and MAC addresses.

The advantages of this method:

• 🔄 Data is updated in real time (with an active connection to the same Wi-Fi).
• 📱 You can quickly disconnect an unknown device directly from the app.
• 🔒 No need to remember the router's IP address or login/password.

Flaws:

• ❌ Not all router models are supported (for example, older versions ZTE may not be displayed).
• ❌ The functionality is limited compared to the web interface (you can’t configure a MAC filter or change the Wi-Fi channel).

3. Viewing connected devices via the command line (Windows)

If you have a computer running Windows, you can see a list of devices on the local network using standard system tools. This method will not show All Wi-Fi-connected gadgets (only those that actively exchange data), but it will help identify suspicious activity.

Instructions:

1. Click Win + R, enter cmd and press Enter.
2. Enter the command:

   arp -a

   It will display an ARP (Address Resolution Protocol) table with the IP and MAC addresses of the devices your computer has communicated with.

3. To see only active connections to the router, enter:

   ping 192.168.1.1 -n 1 & arp -a

   (replace 192.168.1.1 to your router's IP).

In the results, please note:

• 🔹 Dynamic IP (For example, 192.168.1.100-200) - they are distributed by the router via DHCP.
• 🔹 Static IP (For example, 192.168.1.2) - they could be assigned manually.
• 🔹 Unknown MAC addresses — If you see an address that doesn't belong to your devices, this is a reason to be wary.

To find out which manufacturer a MAC address belongs to, use the first 6 characters (e.g. 00:1A:2B) and check them through the service MAC VendorsFor example, addresses starting with 3C:5A:B4, belong Google (these can be devices Nest or Android), A 78:31:C1 — Apple.

⚠️ Attention: Team arp -a Shows only devices that have recently interacted with your computer. If a third-party device is connected to Wi-Fi but not using the internet, it may not appear. For a complete list, it's best to use the router's web interface.

4. Special programs for network monitoring

If standard methods don't work, you can use third-party utilities. They offer advanced features, such as new device notifications, connection history, MAC address blocking, and even a network map.

Top 3 programs for Windows:

For Android will do:

• 📱 Fing — scans the network, shows open ports, tests speed.
• 📱 Network Scanner — identifies the device manufacturer by MAC address.
• 📱 WiFi Thief Detector — specializes in finding Wi-Fi "thieves."

Example of working with Wireless Network Watcher:

1. Download and run the program (no installation required).
2. Click Start Scanning - after a few seconds a list of devices will appear.
3. Sort by column Device Name or MAC Address.
4. To save the list, click File → Save As (useful for comparison with future scans).

5. How to block unauthorized devices

If you find any unfamiliar devices on the network, you need to block them. Here 3 reliable ways:

Method 1: Blocking by MAC address

The most effective method is to add the MAC address to the blacklist:

1. Go to the router's web interface (instructions in first section).
2. Go to the section Wireless Network → MAC Filter (or Wireless → MAC Filter (for the English version).
3. Select mode Blacklist (Black List).
4. Add the MAC address of the unknown device and save the settings.

Method 2: Change your Wi-Fi password

If you don't want to mess around with MAC addresses, just change your password:

1. In the router's web interface, go to Wireless Network → Security.
2. In the field Network key (Password) enter a new password (we recommend using at least 12 characters with numbers and special characters).
3. Select encryption type WPA2-PSK (or WPA3-PSK, if supported).
4. Save your settings and reconnect your devices.

Method 3: Disabling DHCP and manually assigning IP

This method is suitable for advanced users. If you disable DHCP, the router will stop automatically assigning IP addresses, and external devices will be unable to connect:

1. In the web interface, find Local Network → DHCP Server.
2. Disable DHCP (check the box Disable or Disable).
3. Manually assign IP addresses to your devices (in the network settings on each gadget).

⚠️ Attention: Disabling DHCP may cause problems with devices that don't support manual IP configuration (such as some smart bulbs or speakers). Only use this method if you are confident in your skills.

6. Common mistakes and how to avoid them

When checking connected devices, users often encounter common issues. Here's how to solve them:

• 🔌 The router does not open by IP 192.168.1.1:
  • Check your network connection (Wi-Fi or cable).
  • Make sure the router's IP address is correct (look at the sticker or via the command ipconfig V Windows).
  • Try resetting the router using the button Reset (hold for 10-15 seconds).
• 🔄 The device list is not updated:
  • Reboot your router (unplug the power for 30 seconds).
  • Clear your browser cache or try a different one (for example, Firefox instead of Chrome).
  • Check if your antivirus is blocking access to the control panel.
• 📵 Unknown device disappears and reappears:
  • These could be neighboring routers with the same network name or devices that connect periodically (for example, a friend's smartphone who came to visit you).
  • Turn on hiding SSID (in Wi-Fi settings, disable the option Broadcast network name).

If you suspect your Wi-Fi has been hacked, follow these steps: full reset of the router:

1. Press and hold the button Reset on the back panel of the router (10–15 seconds).
2. After rebooting, enter the control panel with factory data (usually admin/admin).
3. Reconfigure your network with a strong password and MAC address filtering enabled.

What to do if resetting doesn't help?

If after the reset foreign devices continue to appear, it is possible:

1. Your router is infected with malware (update the firmware via the section System → Update).

2. Someone has physically connected to the router via Ethernet (check the cables).

3. You have the WPS function enabled - disable it in the settings Wireless Network → WPS, as it is vulnerable to brute force attacks.

7. Additional security measures

Checking your connected devices is just the first step. To secure your network, follow these recommendations:

• 🔐 Update your router firmware:
  • Go to System → Software Update and check if the version is up to date.
  • If an update is available, install it - this will patch the vulnerabilities.
• 🌐 Disable remote control:
  • Find it in your router settings Remote administration and turn it off (if you are not using it).
  • This will prevent access to the control panel from the internet.
• 📡 Set up a guest network:
  • Create a separate network for guests with limited access to local resources.
  • In routers Sagemcom this is done in the section Wireless Network → Guest Network.
• 🕵️ Enable event logging:
  • In some models (eg, Sercomm RV6699) there is a section System → Journal.
  • It records connection attempts, which will help track down hacking.

If you rent a router from Rostelecom, check the terms of your contract before changing any settings—some settings (such as disabling remote control) may violate the provider's rules.

FAQ: Answers to Frequently Asked Questions

Is it possible to find out what websites a connected device has visited?

No, a router. Rostelecom does not keep a log of visited websites. This requires specialized programs (for example, OpenDNS) or proxy server settings. However, you may see total traffic by devices in the section Statistics or Bandwidth Control (if the feature is supported).

Why are "unknown" devices with names like "Android-1234" showing up in the device list?

This is normal - many devices broadcast randomly generated names on the network (especially Android And iOS (in confidential mode). To identify them:

1. Look at the MAC address and check the manufacturer via MAC Vendors.
2. Disconnect your gadgets from Wi-Fi one by one and watch which device disappears from the list.
3. Use apps like Fing to scan ports - this will help determine the type of device.

How do I permanently block a device so it can't connect even after rebooting the router?

Add its MAC address to blacklist (instructions in fifth section). If your router supports it, you can also:

• 🔒 Bind IP addresses to MAC addresses via DHCP Reservation (then the foreign device will not receive an IP).
• 🔄 Enable Isolation of clients (Client Isolation) - devices will not see each other on the network.

On models Sagemcom These functions are in Wireless Network → Advanced Settings.

Can I see connected devices through my Rostelecom router when I'm not at home?

Yes, but for this you need:

1. Turn on remote control in the router settings (section System → Remote Access).
2. Know white IP address your network (if it is dynamic, use the service DDNS).
3. Connect to the control panel via the Internet by entering in the browser http://[your_IP]:[port].

⚠️ It's not safe - it's better to use a VPN or a mobile app Rostelecom, if it supports your router model.

What should I do if I forgot the password for my router's web interface?

There are two options:

1. Factory reset:
   • Click the button Reset on the router (hold for 10-15 seconds).
   • Login and password will become standard (admin/admin or as on the sticker).

Recovery via Rostelecom Personal Account:

• In some cases, the password can be reset through the application (section Devices → Router Settings).

If nothing helps, contact support Rostelecom - they can reset the password remotely (for rented routers).
