Is your Wi-Fi being hacked? Signs that your neighbours are stealing your Wi-Fi!

Having a wireless network in your home is convenient, so much so that your Wi-Fi-deficient neighbours may be tempted to hop onboard. From the neighbours’ point of view, sharing your Wi-Fi signal is certainly appealing; it saves them money and frees them from the hassle of setting up and securing their own wireless networks.

From your perspective, however, having your Wi-Fi signal compromised is a real problem. Not only will those uninvited guests slow down your Wi-Fi signal, but the unauthorised activity could also compromise the security of your entire network.

So how do you know if the neighbours, or anyone else for that matter, are stealing your Wi-Fi signal? While the best way to detect unauthorised activity on your Wi-Fi network is with a special app (more on that later), there are some telltale signs and symptoms to watch out for. You should suspect Wi-Fi theft, and download a Wi-Fi activity tool, if you notice any of the following:

• A sudden slowdown in your Wi-Fi signal – The addition of unauthorised devices can split your Wi-Fi signal and bring your performance to a crawl.
• Frequent disconnections – An increase in disconnections or could be the first indication of a stolen Wi-Fi signal.
• High levels of activity on your Wi-Fi router even when no one is actively using their devices – If the lights on your modem and router are constantly blinking, someone could be stealing your signal.
• Buffering during video playback or online streaming – If you are seeing buffering where there was none before, your Wi-Fi signal may be compromised.
• An inability to connect – In extreme cases, the thieves hijacking your Wi-Fi signal may even change your password, locking you out of your own network. When that happens, your only choice may be to do a hard reset on the router and re-deploy your security settings.

If you suspect that someone is stealing your Wi-Fi signal, it is important to scan your network and find the intruders. You may think that letting the neighbours share your bandwidth is no big deal, but in fact, it puts your security at risk in a big way.

The best way to find and lock out Wi-Fi thieves is with a special app or program. Apps like Who’s On My WiFi and WiFi Inspector allow users to scan their networks for unfamiliar IP addresses, proving once and for all that those unexpected slowdowns and high activity levels are the result of unauthorised access.

There’s also the Fing network scanner app to detect intruders and immediately discover all devices connected to any Wi-Fi network.

If your scan shows that someone is indeed sharing your wireless signal, it is time to change your Wi-Fi password. Check your router manufacturer’s website for specific instructions on how to change your password and lock down your network – and be sure to do periodic scans to make sure those unwanted visitors are truly gone.

Thank you for this article. Our router has been hacked by neighbours who we believe have committed serious criminal acts using our router. We do have evidence of the hack and would like to make contact with the author of this post to discuss an article. Agree that the wider public (including us) had been under the assumption that this is generally done just to ‘piggy-back’ a WiFi connection – but there is often a much more sinister motive.

I believe my internet signal at my address is being hacked and that it has resulted in a criminal conviction where a young innocent person (18) was sent to prison . I believe my internet signal is still being hacked at my home even any mobile phone is being hacked ( they are listening to calls watching texts etc.) still and even this computer i am typing this on at the moment is not safe . any use of the google network at my address is being hacked .I have tried and failed once already to leave this comment . The general public need to be aware . google chrome is not safe even on a mobile . I don’t know what to do or where to turn


Neighbours hacking into WiFi are dangerous cyber criminals who are every bit as serious a threat to their victims as are burglars. The obsession that drives them to commit the crime in the first place won’t just go away when they get into your network. They will clone your devices and indulge in nefarious activity. If they are sitting outside your house they are carrying out that activity on your IP address. Never underestimate the deadly nature of neighbour hackers.
