Cannot

wirelessly
Wireless
projection
uses
a
wireless
adapter
card
(WLAN)
in
your
laptop
computer.
Therefore,
you
cannot
connect
to
the
Internet
unless
you
have
a
second
wireless
adapter,
or
you
have
a
wired
connection.

projection
session
the
WLAN
adapter
is
unplugged
or
disabled,
but
the
projector
screen
maintains
the
last

for
several
seconds

the
possibility
of
unreliable
networks,
the

takes
some
time
to
realize
that
the
WLAN

in
the

has
been
disabled.
The

about
30
seconds
before
ending
projection.
You
can
quit
the
wireless
projection
immediately
by
