With Wi-Fi Networks Becoming More Vulnerable, Opportunistic Neighbors Can “Piggyback” on Your Connection. Learn How to Identify Intruders, Block Unauthorized Access, and Strengthen Router Security in a Few Steps
Even without any change in usage, have you felt that your internet is slower than usual? Well — the problem might be closer than you think: perhaps in the apartment next door.
It is increasingly common for neighbors to take advantage of unsecured Wi-Fi networks or weak passwords to connect without permission.
The good news is that there are simple ways to find out if this is happening and, even better, to kick them off your network.

Identify Signs of Intrusion
The first step is to pay attention to suspicious signs. If the internet is slow, data consumption seems high, or if there are sudden connection drops, there may be someone “piggybacking” on your Wi-Fi.
In this case, access the router’s panel and check the list of connected devices. Just type the device’s address (like 192.168.0.1 or 192.168.1.1) into the browser and log in with the username and admin password.
There, you can see all the connected devices — smartphone, computer, TV, game console — and identify any strange names or addresses.
How to Remove an Intruder from Your Network
If you find any intruder, removing them is simple. Access the router’s panel and block the unknown device.
Next, enable the MAC address filtering to prevent them from reconnecting.
And, most importantly, change the Wi-Fi password. By creating a new password and reconnecting only your devices, all intruders will be automatically disconnected.
Strengthen Network Security
To prevent unauthorized access, it is important to reinforce the router’s security. Use more recent protection protocols, such as WPA2 or WPA3, which offer stronger encryption.
Create long and complex passwords, mixing letters, numbers, and symbols. Additionally, also change the router’s default password, which is often “admin” or “1234.” This prevents anyone from easily accessing the control panel.
Another tip is to change the network name (SSID) to something neutral, without indicating the model of the device, such as “TP-Link_1234.”
This makes it harder for those trying to exploit known vulnerabilities.
If possible, create a guest network, separate from the main one, with limited access.
When to Call Technical Support
If, even after taking all these measures, the problem persists, check if the router needs a firmware update. Older versions may have security flaws.
It also helps to position the device in the center of the house to reduce the signal range outside.
In more severe cases, when there is suspicion of constant intrusions or illegal usage of the network, contact the internet provider or a specialized technician.
In summary, protecting your Wi-Fi is simpler than it seems. With attention and some basic precautions, you can ensure that only those who should be browsing are online — leaving the neighbor searching for another signal.
