Wi-Fi stealing complaint is very common among us, even many of you share your Wi-Fi password with your friends, neighbors and family members, but you don’t know your friends can share the password with more other peoples you don’t know. You can easily buy an unlimited high-speed plan from your ISP, but there is no way to buy an unlimited speed. There is always a limit, like 10 Mbps, 100 Mbps, etc.

Sometime I feel like my internet speed is very slow, but my plan is all good. At this time, I immediately discover my active Wi-Fi users and block those devices, which are eating too much from my internet connectivity. If you change your Wi-Fi router password, then all devices, including yours will also goes disconnected. Blocking is the best way to handle a Wi-Fi thief.
