This is what the wifi-conf.txt file looks
like. You will enter your network name
and password between the quotes as
shown, and then save over the wifi-
conf.txt file that exists on the
removable SanDisk memory stick

.

When you insert the stick into the
Wavelet USB port with the power off
(standby), the unit will load into
memory the new network name and
password after being powered on for 1
minute.
