Important
Make sure that you have finished the 
instructions from Step 1 Setting Up the 
Machine in the Quick Setup Guide.
These instructions will install your Brother machine in 
a typical small office or home wireless network 
environment in infrastructure mode, using a wireless 
router or access point that uses DHCP to assign IP 
addresses.
If you want to setup your machine in any other 
wireless environment you can find instructions in the 
Network User’s Guide on the CD-ROM. 
You can view the Network User’s Guide by following 
the instructions below.
1 Turn on your PC. Insert the Brother CD-ROM 
labeled Windows Vista™ into your CD-ROM drive.
2 If the model name screen appears, click your 
model name.
3 If the language screen appears, click your 
language. The CD-ROM main menu will appear.
4 Click the User’s Guide.
5 Click the Network User’s Guide.

The WEP key is for 64 bit encrypted networks 
or 128 bit encrypted networks and can contain 
both numbers and letters. If you do not know 
this information you should see the 
documentation provided with your access point 
or wireless router. This key is a 64-bit or 128-bit 
value that must be entered in an ASCII or 
HEXADECIMAL format.
For example:
WPA/WPA2-PSK is a Wi-Fi

 Protected Access 
Pre-share key, which lets the Brother wireless 
machine associate with access points using 
TKIP or AES encryption (WPA-Personal). 
WPA/WPA2-PSK (TKIP or AES) uses a 
Pre-Shared Key (PSK) that is more than 8 and 
less than 63 characters in length.
See the Network User’s Guide for more details.
