Your online business depends on having a good connection. When people jump on your network it can seriously slow your bandwidth down. When you plan to live stream, hold an online meeting with a client or you are hosting a webinar then you understand every bit of band width is necessary for quality video.
I found this video on my search to see if there was a program that would let me know who was jumping on my Wi-Fi network.
By the way I used the program on a 4G wireless network I have set up in my home and the program does a nice job of letting me know who is jumping on.
