NPort W2150A/W2250A Series Web Console: Network Settings
6-5
The WLAN page is located under WLAN Settings in the Network Settings folder. You can modify IP
configuration, IP address, Netmask, and Gateway for your WLAN.
The NPort W2150A/W2250A Series supports IEEE 802.11a/b/g wireless network interfaces. The supported IP
configurations are static and dynamic (BOOTP, DHCP, or BOOTP+DHCP). Users can set up the IP configuration
with the serial console, or the Web/Telnet consoles through the NPort’s Ethernet interface. For detailed
information about configuring IP configuration, IP address, Netmask, and Gateway, see the previous
section, Ethernet Configuration.
IP Configuration
Default Static
Options Static, DHCP, DHCP/BOOTP, BOOTP
Description This field determines how the NPort’s IP address will be assigned.
Static: IP address, netmask, and gateway are user-defined.
DHCP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP server.
DHCP/BOOTP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP
server. IP address is assigned by BOOTP server if DHCP server does not respond.
BOOTP: IP address is assigned by BOOTP server.
IP Address
Default 192.168.127.254
Options IP address (e.g., “192.168.1.1”)
Description This field is for the IP address that will be assigned to your NPort device server. An IP address
is a number assigned to a network device (such as a computer) as a permanent address on
the network. Computers use the IP address to identify and talk to each other over the
network. Choose a
proper IP address that is unique and valid in your WLAN environment. If
your device server will be assigned a dynamic IP address, set the “IP configuration”
parameter appropriately.
Netmask
Default 255.255.255.0
Options Netmask setting (e.g., “255.255.0.0”)
Description This field is for the subnet mask. A subnet mask represents all of the network hosts at one
geographic location, in one building, or on the same local area network. When a packet is
sent out over the network, the NPort device server will
use the subnet mask to check whether
the desired TCP/IP host specified in the packet is on the local network segment. If the
address is on the same network segment as the device server, a connection is established
directly from the device server. Otherwise, the connection is established through the
gateway as specified in the “Gateway” parameter.
Gateway
Default
Options IP address (e.g., “192.168.1.1”)
Description This field is for the IP address of the gateway, if applicable. A gateway is a network computer
that acts as an entrance to another network. Usually, the computers that control traffic
within the network or at the local Internet service provider are gateway nodes. The NPort
device server needs to know the IP address of the default gateway computer in order to
communicate with the hosts outside the local network environment. Consult your network
administrator if you do not know how to set this parameter.
