Wireless Presentation Gateway
Appendix B: Upgrading the
Wireless Presentation Gateway’s
Firmware
The Wireless Presentation Gateway functions with the use of firmware, pro-
gramming written in the unit’s internal memory. It is this firmware that enables
the Wireless Presentation Gateway to function with the Player and makes it
easy to use.
Occasionally, this firmware will be upgraded, which could increase the
Wireless Presentation Gateway’s stability or make it easier to use. New versions
of the firmware can be found on the Linksys web site at www.linksys.com.
To upgrade this firmware, download it from the website and then double-click
the file wherever it has been saved. You will be walked through instructions on
how to upgrade the firmware.

Ad-hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which
they may be set up: Infrastructure and Ad-hoc. Choosing between these two
modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network
or need to share a peripheral, such as a printer, with the wired network computers,
the wireless network should be set up in the Infrastructure mode, as shown in
Figure A-1. The basis of Infrastructure mode centers around an access point,
which serves as the main point of communications in a wireless network. Access
points transmit data to PCs equipped with wireless network card, which can
roam within a certain
radial range of the
access point.
Multiple access
points can be
arranged to work in
succession to extend
the roaming range,
and can be set up to
communicate with
your Ethernet hard-
ware as well.
If the wireless network is relatively small and needs to share resources only
with the other computers on the wireless network, then the Ad-hoc mode can
be used, as shown in Figure A-2. Ad-hoc mode allows computers equipped
with wireless transmitters and receivers to communicate directly with each
other, eliminating the need for an access point. The drawback of the Ad-hoc
mode is that wireless-equipped computers are not able to communicate with
computers on a wired network. In addition, communication between the wire-
less-equipped com-
puters is limited by the
distance and interfer-
ence directly between
them.
