Authentication and encryption

Most wireless networks use some kind of security settings. These security settings define the authentication (how the device identifies itself to the network) and encryption (how the data is encrypted as it is sent on the network). If you do not correctly specify these options when you are configuring your Brother wireless device, it will not be able to connect to the wireless network. Therefore care must be taken when configuring these options. Please refer to the information below to see which authentication and encryption methods your Brother wireless device supports.

Authentication methods

The Brother printer supports the following methods:
Open system
Wireless devices are allowed access the network without any authentication.
Shared key
A secret pre-determined key is shared by all devices that will access the wireless network.
The Brother printer uses the WEP keys as the pre-determined key.
Enables a Wi-Fi® Protected Access Pre-shared key (WPA-PSK/WPA2-PSK), which enables the Brother wireless printer to associate with access points using TKIP for WPA-PSK or AES for WPA-PSK and WPA2-PSK (WPA-Personal).
Cisco®LEAP (Light Extensible Authentication Protocol) has been developed by Cisco Systems, Inc. which uses user ID and password for authentication.

Encryption methods

Encryption is used to secure the data that is sent over the wireless network. The Brother printer supports the following encryption methods:
No encryption method is used.
By using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.
TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing a message integrity check and rekeying mechanism.
AES (Advanced Encryption Standard) is Wi-Fi® authorized strong encryption standard.
The original Key Integrity Protocol for LEAP by Cisco Systems, Inc.

Network Key

There are some rules for each security method:
Open system/Shared key with WEP
This key is a 64-bit or 128-bit value that must be entered in an ASCII or hexadecimal format.
64 (40) bit ASCII:
Uses 5 text characters. e.g. “WLLAN” (this is case sensitive).
64 (40) bit hexadecimal:
Uses 10 digits of hexadecimal data. e.g. “71f2234aba”
128 (104) bit ASCII:
Uses 13 text characters. e.g. “Wirelesscomms” (this is case sensitive)
128 (104) bit hexadecimal:
Uses 26 digits of hexadecimal data. e.g. “71f2234ab56cd709e5412aa2ba”
Uses a Pre-Shared Key (PSK) that is more than 7 and less than 64 characters in length.
Uses User ID and Password.
User ID: less than 64 characters in length.
Password: less than 32 characters in length.
