In this article, we will delve into the implications of this scenario and explore the potential consequences for your wireless network.
Understanding SSID and Password
Before we dive into the main topic, it’s essential to understand the basics of SSID and password.
SSID (Network Name)
SSID stands for Service Set Identifier, which is the name of your wireless network. It’s the identifier that allows devices to recognize and connect to your network. When you set up a wireless router, you’re prompted to create an SSID, which can be up to 32 characters long. The SSID is broadcasted by the router, allowing devices to detect and connect to the network.
Password (Pre-Shared Key)
The password, also known as the pre-shared key (PSK), is the security key used to authenticate devices to the network. It’s a string of characters that must be entered correctly to gain access to the network. The password is used to encrypt data transmitted between devices and the router, ensuring that only authorized devices can access the network.
