Slow internet speeds, unexpected connection drops, or simply a desire to secure their home network are the main reasons Rostelecom subscribers are asking about monitoring their connected devices. In the age of smart homes and dozens of gadgets in every household, it can be difficult to determine by ear which device is hogging bandwidth. However, if you notice that a page is taking longer to load or your router is flickering more than usual, it's worth auditing your local network.
Modern routers provided by your ISP have built-in activity monitoring tools. You don't need to be a programmer or have extensive networking knowledge to get the full picture. Simply access your router's administrative panel. In this article, we'll cover in detail how to identify uninvited guests, their dangers, and the steps you need to take to secure your connection.
Signs of unauthorized network access
Before you go into the router settings, it is worth paying attention to the indirect symptoms, which may indicate that your neighbors or friends are using your Wi-Fi. Users often ignore these signals, attributing them to bad weather or technical issues with their provider. However, the regular occurrence of these signs is cause for concern.
The first and most obvious indicator is unstable speed. If you're paying for a 100 Mbps plan, but tests show 10-15 Mbps with no active downloads, someone is clearly overloading the channel. You should also pay attention to indicators On the router body: If the WLAN or Wi-Fi light flashes erratically and very frequently when you're not doing anything, this is a sure sign of background activity from other equipment.
Another warning sign could be the inability to access the router's settings. If you try to access the control panel via IP address, but the device refuses or requires a password you haven't changed (and it doesn't work), access to the admin panel may already be blocked by an attacker. In rare cases, devices may display strange system messages or antivirus warnings about port scanning attempts.
⚠️ Attention: Don't be too quick to blame your neighbors for every speed drop. Airwave congestion in an apartment building, with dozens of routers operating on a single channel, can also cause significant interference and reduced throughput.
Preparing for the audit: accessing the admin panel
To begin diagnostics, you'll need a device that's connected to the network via cable or Wi-Fi. This could be a laptop, desktop computer, or smartphone. It's best to use a computer with a wired connection to avoid an unstable wireless signal interfering with the setup process. You'll need to know the IP address of the gateway used to access the interface.
Standard addresses for Rostelecom equipment most often look like this: 192.168.1.1 or 192.168.0.1If these combinations don't work, you can find the exact address on a sticker on the bottom of the router. The factory login and password are also listed there. If you've previously changed these details and forgot them, you'll have to follow these steps. reset settings to factory defaults, which will result in the loss of current configurations.
Open any browser (Chrome, Opera, Firefox) and enter the IP address in the address bar. A login window will appear. Enter your login (usually admin) and password. If the default details don't work and you haven't changed them, your provider may have used a unique combination specified in your contract or on a special card issued upon connection.
What to do if the default password doesn't work?
If the admin/admin combination doesn't work, try checking the information on the sticker underneath the router. It often contains a unique password for each model. If this doesn't help, and you haven't changed the password yourself, the setup technician may have changed the settings. In this case, a full reset using the button on the router case will help, but after that, you'll need to reconfigure the router, including PPPoE or DHCP settings from your ISP.
Analysis of connected devices on different router models
The settings interface depends on the router model installed by your technician. Rostelecom often uses equipment from Sagemcom, Sercomm, Huawei, and D-Link. Despite the external differences, the logic for searching the client list is the same. You need to find the section related to the wireless network or connection status.
In routers Sagemcom And Sercomm (RT-xx, Fxx models) Look for the "Wi-Fi" or "Home Network" tab. There should be a "Client List" or "Statistics" subsection. This will display all devices currently connected to your access point. You'll see their MAC addresses and possibly their names (e.g., iPhone-Alex or Samsung-TV).
For equipment Huawei The path may look like "Basic" -> "WLAN" -> "WLAN Station List." On older D-Link models, look for the "Status" -> "Clients" section. If you see a device you don't recognize, check the MAC addresses of your devices. This is the only reliable method of identification, as device names are often standard (e.g., "Android-xxxx").

Table of standard addresses and logins for access
To simplify the login process, we've prepared a summary table of the most common access details for the equipment used by your provider. Please note that in some cases, this information may be changed on a case-by-case basis.
| Router model | IP address | Login | Password (default) |
|---|---|---|---|
| Sagemcom F@st 2804 | 192.168.1.1 | admin | admin |
| Sercomm RV6688 | 192.168.1.1 | admin | admin |
| Huawei HG8245H | 192.168.100.1 | telecomadmin | admintelecom |
| D-Link DIR-300 | 192.168.0.1 | admin | (empty) |
| Tenda AC6 | 192.168.0.1 | admin | admin |
Methods for blocking unwanted users
Once you've identified the "offender," it needs to be neutralized. The most effective way is filtering by MAC addressThis address is a unique identifier for the device's network card and does not change (with rare exceptions). In the router settings, find the "MAC Filtering" or "Security" section.
Add the MAC address of the other device to the Black List. Once these settings are applied, that device will no longer be able to connect to your network, even if it knows the correct password. An alternative, but more drastic, method is to change the Wi-Fi password. Changing the key will disable all devices, and you'll have to reconnect your devices with the new password.
It's also recommended to disable the WPS function. This technology allows you to connect to Wi-Fi with a simple press of a button, but it has vulnerabilities that can be exploited by attackers to brute-force the PIN code. In the router interface, find the WPS option and set it to "On." Disabled or Off.
Rules for creating reliable Wi-Fi security
To prevent this from happening again, ensure your access point has adequate security. Use an encryption protocol. WPA2-PSK or, if the equipment allows, WPA3WEP and WPA protocols are outdated and can be easily cracked with specialized programs in a matter of minutes.
Make sure your password is complex: use a combination of uppercase and lowercase letters, numbers, and special characters. It should be at least 12 characters long. Avoid using obvious combinations like your date of birth or phone number. Changing your password regularly (every 3-6 months) also improves security.
Don't forget to update your router's firmware. Manufacturers periodically release updates that patch security holes. You can check for a new version in "System Tools" or "Administration" -> "Firmware Update."
⚠️ Attention: The interface and menu item names may vary depending on your router's firmware version. If you can't find the described functions, please refer to the technical documentation for your specific model or contact your provider's support team.
Frequently Asked Questions (FAQ)
Can my neighbor steal my internet if I changed my password?
If you've changed your password to a strong one and are using WPA2 encryption, it's virtually impossible to hack your network using brute-force attacks within a reasonable amount of time. However, if your neighbor has physical access to your router or previously connected via WPS, it's still theoretically possible. After changing your password, be sure to reconnect your devices.
Does the number of connected devices affect internet speed?
Yes, the bandwidth is shared among all active users. If someone is downloading large files or watching 4K videos, other devices may not have enough bandwidth. Furthermore, the router has a limit on the number of simultaneous connections, and if this limit is exceeded, new devices may not connect or may experience errors.
Is it safe to use Wi-Fi monitoring apps on your phone?
There are many apps (such as Fing and WiFi Analyzer) that display a list of devices on the network. They are safe and useful for quick diagnostics. However, blocking and advanced configuration still require logging into the router's web interface, as mobile apps often don't have permission to change router security settings.
What should I do if my speed hasn't increased after changing my password?
The problem may not be with your neighbors, but with the technical condition of the line, overloaded provider equipment, or the router itself. Try rebooting the router, checking the cable, or calling a technician to diagnose the signal strength.
