IEEE 802.11

This Linksys WRT54GS WiFi router from 2005 operates on the 2.4 GHz "G" standard, capable of transmitting 54 Mbits per second.

For comparison, this Netgear dual-band router from 2013 uses the AC standard, capable of transmitting 1900 Mbits per second (combined).

IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands. They are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997, and has had subsequent amendments. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand. While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote capabilities of their products. As a result, in the marketplace, each revision tends to become its own standard.

Types of Encryption | Office of Information Technology

Whole disk encryption, as the name implies, refers to the encryption of an entire physical or logical disk. While this is currently done mostly with software, hardware based disk encryption is a growing technology which is expected to surpass software products for whole disk encryption over the next few years. This form of encryption generally encrypts the entire contents of a disk or volume and decrypts/encrypts it during use after a key has been given. This means the data is protected from situations like laptop/disk loss or theft where the data would be encrypted and require a key to decrypt. It would not protect from situations like sending information over the network (e-mail, websites, etc) or from situations where the decryption key was already entered such as the user walking away from their logged-in computer.

Recommended settings for Wi-Fi routers and access points

The security setting controls the type of authentication and encryption used by your Wi-Fi router, which allows you to control access to the network and specify the level of privacy for data you send over the air.

Set to: WPA2 Personal (AES)

WPA2 Personal (AES) is currently the strongest form of security offered by Wi-Fi products, and is recommended for all uses. When enabling WPA2, be sure to select a strong password that can't be guessed by third parties.
