GENERAL PREPARATION 

 
1) Go to Buffalo web-site, buffalotech.com, download the following: 
    - firmware update, comes with LSupdater program 
    - unzip file 
 
Note: At the time of this writing, our NAS came with firmware version 1.01. The 
update is version 1.31. To the best of my understanding, the drive(s) installed in 
the NAS stores the firmware data, it is not written to the hardware. LSupdater 
writes the firmware to the hardware and the drive. LSupdater also forces drive 
initialization and formatting. There are options to turn on or off formatting. 
 
2) Use a WIRED computer on your network, not wireless 
 
3) Enable DHCP on Router, if disabled 
 
3) Install Buffalo Navigator software from CD that came with NAS
