How to Get Xfinity Network Security Key

The Xfinity gateway has a powerful range of data transmission that could boost the internet signals for over a hundred feet away. And because of that, people are liable to join your network if it is not secured with Xfinity network security key.

We understand that sharing might not be the bigger issue but the risk of having a public network increases the chances of being hacked. Which is why it is recommended that you keep your network secured at all times.

With Xfinity network security key, one can avoid being easy targets for hackers and their spyware and malware devices. It encrypts your data that is transmitted using the best of security systems (The old WEP, the decent WPA and then the newest WPA2)

What is Xfinity network security key?

As the name defines, a network security key is the network protection. So as not to be confused with the choice of word, the security key can also mean the passcode, PIN, password or any protocol you have in place to protect your system.

Types of network security

As aforementioned, there are three types of encryption methods that are used by the Xfinity network security keys, and your system automatically uses one.

WEP (Wired Equivalent Privacy)

The WEP is the oldest of the three and is regarded as obsolete in today’s wireless security protocol. However, it remains in use by older devices.

That said, it is very prone to brute-force hacking and it is harder to configure, unlike the WPA protocols. If you are setting up a new system, it is recommended to avoid networks with this system.

WPA (Wi-Fi Protected Access)

WPA is the successor of WEP. It is an intermediate protocol with advancement and improved features compared to the WES.

Still, it is lacking in some departments compared to WPA2. Suffice to say, hacking has advanced and has left WPA in the dust.

WPA2 (Wi-Fi Protected Access 2)

WPA2 uses AES encryption (meaning Advance Encryption Standard). AES is grouped into three phases, 128, 192, 256 and they use their respective key lengths to encrypt/decrypt a block of messages. This is among the reason why it is most secure wireless network protocol.

The WPA2 is the most preferable and you should upgrade if you use any of the previous protection network.

When your network is installed, it will be protected by a complex string of randomized numbers and letters. Like most strong passwords, it can be easy to forget.
