Minor nit in the help.html file under the section of "Installing firmware with tftp".   The IP address of the Bullet you want to 'tftp' the firmware to will be 192.168.1.20 according to Ubiquiti's website.  This is also the address I used when tftp'ing the latest firmware into the Bullet I have.

The 192.168.1.1 IP address is that used by a WRT54G in the same circumstances at power up.  Maybe not always the case but I seem to recall this is what a number of Atheros-based wireless routers use. Naturally, your mileage may vary.  :)
