How to Know If Someone Is Using Your WiFi

A slow internet connection does not always mean someone is stealing your WiFi. It could be your provider, your router, thick walls, too many devices, old equipment, or a crowded evening network. But if your internet suddenly becomes unreliable, your data usage rises, or unfamiliar devices appear on your router, it is worth checking.

The good news is that you do not need to be a cybersecurity expert to investigate. Most routers and internet provider apps now show connected devices, and your phone or laptop can also help you spot unusual activity. The goal is not to panic, but to confirm whether the devices on your network are actually yours.
