Web: menu “SERVER CONFIGURATION”, section “Wireless Parameter”.
Telnet: “ServerConfig”, option “Wireless”
This section is of course only available on the NetCom Plus with WLAN option class of devices,
or when the external WLAN kit is installed. To operate a Wireless device, a lot of parameters
are required. The configuration in the NetCom
+
is reduced to a small set of them, for ease of
configuration.

Figure 63: Wireless Parameter
The
Chipset
is provided as a read-only parameter. This defines the hardware base for the WLAN
functions. This model of NetCom Plus with WLAN option supports the TI WL18XX circuits.
SSID
is the «Service Set Identifier». This is used to get access to radio cells established by an
Access Point. By default the NetCom
+
operates as an Access Point and uses an SSID built from
the serial number. This means it is the same as the default NetCom
+
s name.
The
OperationMode
is selectable as
AP
for «Access Point Mode», and
infra
for «Infrastructure
Mode».The mode of
AP
is the factory configuration, here the NetCom Plus with WLAN option
operates as an Access Point by itself. Computers and other WLAN stations can connect to it, and
via the NetCom
+
to each other. This supports Windows 7 and later versions, were the classic mode
of Ad-hoc operation has been removed. Also some modern hardware does not support the insecure
Ad-hoc mode anyway.
The other mode named
infra
is required to connect as a client to an Access Point. Other wireless
stations such as a PC or Laptop use that Access Point to transfer the data to the NetCom
+
.
WLAN as of IEEE 802.11 b/g/n defines fourteen possible Channels (i.e. predefined frequencies) to
use with WLAN devices. Some of these frequencies are restricted in certain countries. Please check
