Wifi, as common knowledge, is the wireless accessing point which allows users to access the Internet under the same IP address. Wifi is only useful in a particular area where it’s set, and the size of space is variable depending on the strength of the source of the Internet.Wifi network
Not all people staying in the coverage of wifi can access to the Internet-sourced by that IP address but only those having the correct password. We can say wifi works as a personal network which manages devices under the same IP address.
The IP address for personal use is usually 192.168.10.1, or we have other branches of IP address raised by the original such as 192.168.10.xxx.
