Key point of network securities.

 A network security key is a password that protects your network. If you have a WiFi router at home, you will need a code to connect the devices. This Wi-Fi password is the key to the security of your network.

 Network security keys block three types of network encryption. 

 Wired Equivalent Privacy (WEP) 

 WEP is an older wireless security protocol that is still available on older systems. 

 It's tricky and difficult to set up, so I suggest you don't take the risk  using WEP. 

 Wi-Fi Protected Access (WPA) 

 WPA is the successor to WEP. While WPA is certainly an advanced protocol with additional features, it is still insecure and vulnerable to cyber attacks. 

 Wi-Fi Protected Access 2 (WPA2) 

 WPA2 uses AES encryption, the most secure wireless network protocol. Encrypt online data to prevent unauthorized access. 

 After the network is set up, it is secured with a complex series of random numbers and letters. Like most strong passwords, it can be easily forgotten. 

 If you want to know or change your network security key, here's what you need to know. 

 Where can I find the network 

 security key? If you hold the 

, you can see the router itself. 

 The password must be displayed somewhere  and is often printed on a small sticker. If the router itself does not display the password, check the box that came with it  or the documents that came with it. 

 You can ask someone else to do the same and give you the password, but it's common for the router to be overlooked. You definitely don't want  visitors to have to crawl behind your sofa to find it. 

 There is a better way. 

 If your computer is already connected to a wireless network, the network key is stored here. This means it can automatically connect  as soon as it is in range and  find data through the device.
