Authentication methods

Open system



Wireless devices are allowed to 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 wireless printer uses a WEP key as the pre-determined key.



WPA-PSK/WPA2-PSK

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).

Encryption methods



None

No encryption method is used.



WEP

When using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.



TKIP

TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing, a message integrity check and

rekeying mechanism.



AES

AES (Advanced Encryption Standard) is the Wi-Fi

Network key



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. "WSLAN" (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"



WPA-PSK/WPA2-PSK and TKIP or AES

Uses a Pre-Shared Key (PSK) that is 8 or more characters in length, up to a maximum of 63 characters.
