Configuration Options
The configuration options are described below.
Mode
Two modes are available in Transport:
• Infrastructure - All communication is done through
TransPort to other computers, not from one computer to
other as in the Ad Hoc mode.
• Ad hoc - This mode is peer-to-peer or totally wireless;
client computers are not connected to a wired LAN. All
communication is from computer to computer.
SSID
The Service Set Identifier is the last eight numbers of your
TransPort serial number. All components of the network must
use the same SSID. Make sure that your TransPort has the
SSID setting. For more information, see “View Configuration”
on page 35, or “Changing the TransPort Radio Settings” on
page 39.
Ethernet conversion
This field sets the conversion method used to transmit old-style
(DIX) Ethernet frames over the 802.11 wireless link. You
should use the default setting. Remember that all client
computers on the network must have the same setting.
If you want to connect to another network, you can change this
setting to match the network’s setting.
The three types of Ethernet conversion are:
• Encapsulated - This setting takes the entire Ethernet frame
and puts it into a 802.11 frame. (A frame contains the
destination address in addition to the data.) It is used for
compatibility with some older 802.11 implementations
and normally should not be used.
• 802.1h - This setting converts DIX (Digital Intel Xerox)
Ethernet frames to 802.11 frames with a “tunneled” (or
redirected) 802.2 SNAP (Subnetwork Access Protocol)
header. On reception, all “tunneled” frames are converted
to DIX frames. (The DIX Ethernet is a precursor of the
IEEE 802.3 Ethernet.)
