Modern wireless internet users often experience unexplained drops in connection speed, especially in the evening when network load is at its highest. If you notice that pages are taking longer to load than usual or high-definition videos are constantly buffering, this could be the first sign that unauthorized individuals have gained access to your personal network. Owners of this brand's equipment Fly (Letai), often supplied by ISPs, must be able to respond quickly to such incidents to maintain data privacy and connection stability.
Fortunately, the router's built-in software interface allows for detailed monitoring of all active connections in real time. You don't need to be a professional network administrator to understand the basic traffic monitoring features and client lists. All you need is a device with a browser and the standard URL for accessing the control panel.
In this guide, we'll detail the step-by-step process for logging into the web interface, learn how to read the active client table, and, most importantly, consider methods for protecting your home network perimeter from intruders.
Network congestion indicators and signs of hacking
Before moving on to technical settings, it's important to understand the specific symptoms that indicate a problem. Users often confuse provider technical issues with bandwidth congestion from third-party devices. However, there are clear indicators that should be ignored. not recommendedIf the router's indicator lights are flashing rapidly even when you're not downloading anything, it's time to check.
Modern routers They process huge amounts of data, and background activity on someone else's device may be invisible but have a significant impact on performance. For example, someone could use your connection to mine cryptocurrency or download large files via torrent clients. This creates a constant high load on the router's processor and communication channel.
⚠️ Attention: Some smart devices (lamps, sockets, refrigerators) can constantly transmit small data packets. Don't rush to block unknown MAC addresses until you're sure they're not your own IoT devices.
Another sign is a change in the admin panel password or the inability to access the settings with known credentials. This indicates that the attacker has not only accessed the internet but has also gained complete control over the equipment. In this situation, the standard procedure for viewing the client list may no longer be available without a factory reset.
Preparing for diagnostics: accessing the interface
To begin diagnostics, you need to connect to the router's network, either physically or wirelessly. It's best to configure the settings from a computer connected via cable to avoid losing connection to the device if you change security settings. However, you can also log in via WiFi from a smartphone or tablet.
Open any browser and enter the default gateway IP address in the address bar. For most models Fly This 192.168.1.1 or 192.168.0.1The exact address is often listed on a sticker on the bottom of the device, along with the factory username and password. If the default addresses don't work, you can check your gateway using the command line.
In the login window that opens, enter your credentials. If you've previously changed the administrator password, use it. If you're logged in using factory settings and haven't changed them, your credentials can also be found on the label. After successful login, the main control panel will open, displaying the connection status and basic settings.
Search for active clients in the DHCP menu
The interfaces of different firmware versions may differ visually, but the logic behind the information layout remains the same. You need to find the section responsible for the local network. It's usually called LAN, Local Network or Net. Within this section, look for the subsection DHCP Server or Client list.
This is where the IP address allocation table is stored. Protocol Dynamic Host Configuration Protocol Automatically assigns an address to each device requesting a connection. The table displays a list of all devices that have recently received an IP address. This is the most reliable way to detect "ghosts" on the network.
Please note the table columns: IP Address (issued address), MAC Address (unique identifier of the network card) and Lease Time (lease time). If you see a device with an expired lease time, it may already be disabled, but the entry remains in the cache. Active devices usually have a long lease time or the status "Online."
| Parameter | Description | What to look out for |
|---|---|---|
| IP Address | A unique address on a local network | Does the subnet (first three digits) match yours? |
| MAC Address | Physical address of the device | The first 6 characters indicate the manufacturer |
| Host Name | Device name (often specified by the user) | Familiar names (iPhone, PC, TV) |
| Expire Time | Remaining rental period | Active devices have high value |
☑️ Checking the client list
Analyzing the list of connected devices
Once you've received the list, you may encounter a situation where you don't recognize some devices. Don't panic ahead of time. Modern homes are filled with technology we often forget about: smart plugs, IPTV set-top boxes, game consoles, e-readers. Each of these has its own network interface.
For identification, use the first six characters of the MAC address (OUI). There are databases online that allow you to identify the network card manufacturer using these characters. For example, if the address begins with 00:1A:2B, this may indicate a brand device Samsung or AppleIf you see a device from an unknown manufacturer that you definitely don't have in your home, that's a warning sign.
It's also worth paying attention to the number of active connections. If you only have one smartphone and one laptop in your apartment, and the list shows 10 devices, then your WiFi channel Used by third parties. Devices with default names like "android-xyz" or "unknown" are especially suspicious unless you've renamed your devices yourself.
⚠️ Attention: Some privacy protection apps can mask your device's MAC address by generating random values. Before blocking a fake address, check the privacy settings on your smartphones.
It's important to distinguish between wired (Ethernet) and wireless (WiFi) connections. In the router's advanced settings, you can often see a distinction by interface type. If an unknown device is connected via a cable, someone may have physical access to your apartment or building's electrical panel.
Methods for blocking uninvited guests
Once the intruder is identified, their access must be immediately restricted. The simplest, but not the most reliable, method is to change the WiFi password. This will disconnect all users, and you'll have to reconnect your devices. However, this ensures that the old password is no longer valid.
A more professional approach is to use the function MAC filtering. In the wireless network settings (Wireless Settings) Find the "MAC Filter" or "Access Control" section. Here you can create a "White List" (only specified accesses are allowed) or a "Black List" (specified accesses are denied). Adding the intruder's MAC address to the blacklist will immediately block their access.
We recommend using "Whitelist" mode if your number of devices is finite and doesn't change frequently. In this case, even if an attacker learns your password, they won't be able to connect because their physical address isn't included in the router's whitelist.
What happens if I change my WiFi password?
All devices saved on the network will lose connection. You'll have to manually enter the new password on each smartphone, TV, and laptop. It's inconvenient, but effective.
After applying the settings, be sure to click the "Save" or "Apply" button, as routers Fly Changes may not be applied without a reboot or confirmation. Check the client list again in 1-2 minutes—suspicious entries should disappear or be marked as "Blocked."
Strengthening wireless network security
Simply removing the guest isn't enough; you need to close the door they entered through. The first step is to check the encryption type. Make sure that the security settings (Security) protocol selected WPA2-PSK or the newest WPA3Using legacy WEP or an open network makes your traffic readable to any neighbor with basic security skills.
Password protection should be comprehensive. Your WiFi password should contain at least 12 characters, including uppercase and lowercase letters, numbers, and special characters. Avoid obvious combinations like your date of birth or phone number. Your router's administrator password should also be changed from the factory default to prevent anyone from changing your settings without your permission.
Disable the feature WPS (Wi-Fi Protected Setup). Despite the convenience of a push-button connection, this protocol has known vulnerabilities that allow someone to brute-force the PIN code and gain network access in minutes using specialized software. Find the WPS option in the router menu and set it to "On." Disabled.
Update your router firmware regularly. Manufacturers release updates that patch security holes. You can check for a new version in the section System Tools → Firmware Upgrade. Up-to-date software ensures that your router Fly protected from known exploits.
Frequently Asked Questions (FAQ)
Can my neighbor see my files via WiFi?
If you have a network-attached storage (NAS) device configured on your network or shared folders on your PC, then theoretically yes. However, if you use strong WPA2 encryption and a complex password, it will be extremely difficult for a neighbor to break into your network. The main risk is the transmission of unencrypted data (login/password) over open channels if you visit websites without the HTTPS protocol.
Will my router reset if I unplug the power cord?
A normal power cycle does not reset user settings, the WiFi password, or the client list. To perform a full factory reset, you must hold down the button. Reset on the device body for 10-15 seconds while the power is on. Be careful when using this button.
Why does "Unknown Device" appear in the client list?
This occurs when a device doesn't transmit its hostname when requesting an IP address or the router fails to recognize it. This behavior is often seen in smart home devices (cameras, sensors) or gadgets with MAC address randomization enabled for privacy purposes.
Does the number of connected devices affect internet speed?
Yes, the bandwidth is shared among all active users. If one device starts downloading large files or watching 4K video, the others may not have enough bandwidth, resulting in lag and slow page load times.
How often should I change my WiFi password?
At home, it's sufficient to change your password every 6-12 months or if you suspect a breach. In office networks or areas with a large number of temporary visitors, it's recommended to change your password more frequently, for example, once a month.
