It’s not easy to find out if someone has hacked the WiFi. The list of network administrators, you’ll most likely notice it from the router. The router’s router has all the devices currently connected.
However, he often has cryptic names that you can edit. If you identify all of the devices you know in this way, all those still connected will need to use the WLAN without authorization.
Now you can check this list regularly, but first of all it’s hard and won’t take the worst of 99 percent of the cases. Second, it’s confusing, because you usually have more devices connected to the WiFi network than you thought.
Although many people live in your apartment and that person is a household owner, it’s often difficult to tell a thing from the tip of the routers section for you, whether something is a device from your house or unauthorized access; however, when the user is able to turn it over to the routers section by definition.
You’re likely to notice a hacked wifi by the effects of it. Maybe your Internet access is suddenly paralyzed (because the hacker uses your bandwidth) or end devices go haywire, essentially turns on and off without doing anything (because the hacker controls them remotely) or your data disappear and you may be blackmailed on the one or even on the other.
