Slow internet speeds, constant connection drops, and the inability to load a webpage in a browser are often the first signs that someone is using your wireless network. In densely populated urban areas, the Wi-Fi signal often extends beyond your apartment, making your hotspot accessible to neighbors or passersby. If you use Rostelecom, the routers provided by the provider or purchased independently offer powerful tools for monitoring connections.
Understanding that, How to see who is connected to your Rostelecom Wi-Fi router, is a basic skill for ensuring network security. Modern devices such as Sagemcom, Eltex or Upvel, allow detailed monitoring of each device's activity. This isn't just a way to control traffic, but also to protect personal data from potentially unsafe devices on the local network.
In this article, we'll walk you through a step-by-step process to help you identify intruders and block access to your network. You'll learn how to distinguish your devices from others, block intruders' MAC addresses, and set up secure encryption to prevent bandwidth congestion from ever happening again.
Indirect signs of the presence of strangers on the network
Before delving into your router's technical settings, it's worth paying attention to indirect symptoms that may indicate unauthorized access. Users often notice that the wireless network indicator on the device is unusually active, even when all other devices are in sleep mode or turned off. This may indicate background data transfer by someone else.
Another warning sign is a sharp drop in page loading speed or buffering of high-definition video, even though your data plan allows for smooth streaming. If you don't have torrents or cloud syncs enabled and your internet is slow, your channel may be clogged with other people's traffic. You should also be wary if the indicator WAN or Internet lights up or flashes at a high frequency when there is no active action on your part.
⚠️ Attention: Don't confuse background operating system updates or the operation of smart devices (cameras, speakers) with hacker activity. Modern gadgets can consume data without the user's knowledge.
For initial diagnostics, you can use specialized applications on your smartphone, such as Fing or WiFi Analyzer, which scan the airwaves and display the number of active clients. However, the most accurate and reliable information is provided only by the Rostelecom router's administrative panel, which we'll explore next.
Login to the Rostelecom router control panel
To access the list of connected devices, you need to log in to the router's web interface. This can be done through any browser on a computer or phone connected to the network. Enter the gateway's IP address in the address bar. For most Rostelecom router models (Sagemcom, Eltex, Sercomm), the default address is 192.168.1.1 or 192.168.0.1The exact address is often indicated on a sticker located on the bottom of the device.
After entering the address, the system will ask for your login and password. By default, this information is also included on the manufacturer's sticker on your provider's equipment and is often the combination "admin" or a unique code. If you previously changed your login information and forgot it, you may need to perform a factory reset, which will temporarily disconnect your internet connection until you can set it up again.
The interfaces of different models may differ, but the logic remains the same. You need to find the section related to the wireless network or device status. In older firmware versions, this may be a tab Status or Wireless, in the new ones - Local area network or My devicesIt's important to keep a list of your gadgets handy to avoid accidentally blocking your TV or game console.
What should I do if the login page doesn't open?
If your browser says "Unable to access the site," check that your device is connected to the router's Wi-Fi network and not your mobile data. Also, try clearing your browser's cache or using incognito mode. In rare cases, the gateway address may be changed in your computer's TCP/IP settings.
Analyzing the list of connected clients
After successfully logging into the router management system, you need to find the section displaying current clients. Depending on the hardware model (e.g., Sagemcom F@st 2804 or Eltex NTU-RG-1401G-WThis section may be called "Client List," "DHCP Lease," "WLAN Status," or "Network Map." This is where you'll see a complete picture of who's currently using your internet bandwidth.
In the list that opens, you'll see a table with several columns. Typically, it lists the IP address, MAC address, device name (Hostname), and connection type (Wi-Fi or LAN). MAC address — is a unique identifier for a network card, which is the most reliable method of identification. Device names can be unintelligible (for example, "android-123" or "unknown"), so checking the MAC address is mandatory.
| Parameter | Description | Where to find on the device |
|---|---|---|
| IP address | Temporary address on the local network | Network Settings -> Properties |
| MAC address | Physical unique identifier | About the system -> General information |
| Hostname | User-defined device name | Settings -> About phone/tablet |
| Type | Connection method (Wireless/LAN) | In the router interface column |
To effectively analyze the list, it's recommended to write down the MAC addresses of all your devices in advance. This can be done in the settings of each smartphone, laptop, or Smart TV. Then, simply compare the resulting list with what's displayed in the router dashboard. Any device you can't identify is a potential intruder.
☑️ Checking the client list
Blocking unwanted devices and changing passwords
If you find other people's devices in the list, the most effective and fastest way to protect yourself is to completely change password to the Wi-Fi network. This action will force all devices to disconnect, requiring them to enter a new key to reconnect. You can find the setting in the WLAN, Wireless or Wireless network -> Security.
Create a complex password that includes mixed-case letters, numbers, and special characters. Avoid simple combinations like your date of birth or phone number. After changing the password, the router will reboot the wireless network module, disconnecting all clients. You'll have to reconnect your devices using the new credentials.
An alternative or additional method is MAC address filtering. In the security settings (often in the MAC Filter or Client filtering) You can add MAC addresses of intruders to a blacklist. However, this method is less secure, as an experienced user can clone their device's MAC address to an authorized one. Therefore, changing the WPA2-PSK password remains the gold standard for security.
⚠️ Attention: When changing your password or setting up filtering, make sure you don't lock yourself out, especially if you're configuring your router remotely or via Wi-Fi. It's best to have an Ethernet cable handy for a direct connection to your PC.
Setting up encryption and strengthening network security
After clearing your network of intruders, it's important to ensure such actions don't happen again. Choosing the right encryption type is key to protecting your network. In the wireless security section of your router's interface (Security Mode) always choose WPA2-PSK or, if the equipment supports it, WPA3Outdated WEP and WPA-TKIP protocols can be easily cracked by automated scripts in minutes.
Also worth paying attention to is the function WPS (Wi-Fi Protected Setup). It's designed to simplify connecting devices with the push of a button, but it often contains vulnerabilities that allow hackers to recover the PIN code and gain access to the network. It's recommended to find the menu item WPS and switch it to the state Disable or Off.
It's a good idea to change the password for accessing the router's control panel (admin panel). By default, many users leave the password set to admin/admin, which gives complete control over the device to anyone connected to the Wi-Fi network. Change this password in the section System tools or Administration.
Frequently asked questions and problems during verification
When monitoring a network, users often encounter technical nuances that can cause difficulties. For example, a device may appear in the list as "Unknown" or have a strange character set. This is normal for many IoT devices (smart light bulbs, plugs), which do not broadcast their friendly name to the network.
Another common situation is when the number of connected devices in the list exceeds the number of gadgets in your home. Keep in mind that modern smartphones can create two entries: one for the 2.4 GHz frequency and one for the 5 GHz frequency, if the router broadcasts two networks with different names (SSIDs). Virtual network adapters and game consoles are also worth considering.
If you suspect that you are being “jammed” or that complex methods of bypassing protection are being used, it makes sense to look at the router logs (section System Log). There may be records of login attempts with incorrect passwords, confirming external activity. Regularly checking these parameters will help keep your network secure.
Can my neighbor see what websites I visit if he's connected to my Wi-Fi?
Simply connecting to your Wi-Fi network doesn't automatically grant access to your browser history or chat content if websites use the HTTPS protocol (which is now the standard). However, while on the same local network, Man-in-the-Middle attacks are theoretically possible if the victim's device isn't protected. Therefore, you shouldn't trust other people's devices on your network.
Why does the router show a device that is currently turned off?
The DHCP (address lease) section often stores records of previously connected devices. The lease time can range from a few hours to several days. If a device simply goes into sleep mode or moves out of Wi-Fi range, it may remain listed as "active" or "leased" until the lease time expires.
How often should I change my Wi-Fi password?
Cybersecurity experts recommend changing your Wi-Fi network password every 3-6 months, especially if you frequently grant access to guests or use simple passwords. If you use a complex, unique password and don't share it with anyone (guests are given a QR code or have guest access), you can change it as often as once a year.
Does the number of connected devices affect internet speed?
Yes, it does have a direct impact. The Wi-Fi channel is shared among all active users. If one device starts downloading large files or watching 4K video, the others will only get a small portion of the bandwidth. Furthermore, a large number of devices puts a strain on the router's processor, which can lead to overheating and freezing.
What should I do if I changed the password, but someone else's device still connects?
This is virtually impossible with properly functioning hardware and correct WPA2/WPA3 encryption settings. If this happens, check to see if WPS is enabled (it should be disabled). Also, make sure you've saved the settings (Save/Apply) and rebooted the router. In rare cases, a full reset and reconfiguration of the router may be required.
