(PRL) regions. The PRL contains information
regarding allowed systems (GSM/UMTS) and bands.
This information is used by the Ericsson W3x during
the system selection and acquisition process, initially
and when the Ericsson W3x is roaming.
By setting a specific region, the Ericsson W3x favors
bands within this region.
Included regions in the list are:
Global
Europe/Rest of the World
North America
Australia
Japan
H3G, W2100, G900/1800
Note:
A restart is required if changing this setting.
3G Settings
Select the frequency bands to be used for a 3G
mobile connection; 850, 1900, 2100.
2G Settings
Select the frequency bands to be used for a 2G
mobile connection; 850, 900, 1800, 1900.

Description
IP address:
The LAN IP address of the Ericsson W3x.
Subnet mask:
The subnet mask, which determines the range of IP
addresses on the subnet.
The LAN IP address and subnet mask can be changed, but before you do
this, consider the following:
•
Make sure that the new address is not included in the DHCP server IP
address range, displayed in the “DHCP Server” section. The default
range is 192.168.1.2 – 192.168.1.100.
•
Make sure that the DHCP server IP address range is included in the
new subnet. If you want to change the subnet not to include the DHCP
IP address range, you first have to disable the DHCP server.
•
If port forwarding rules have been configured, those settings have to be
removed before changing the IP address or subnet mask. For
information, see section 3.7.3 –
Port Forwarding
.
To change the LAN IP address or subnet mask of the Ericsson W3x, type
the new values in the corresponding fields and click
Apply
to save the
settings.
Note:
If you change the LAN IP address while connected to the WUI, you
will be disconnected. You have to redirect the web browser to the
new address in order to confirm the new settings. Type the new
LAN IP address in the
Address
(URL) field and press Enter.
3.5.2
DHCP Server
The Ericsson W3x incorporates a DHCP (Dynamic Host Configuration
Protocol) server which dynamically assigns IP addresses to devices on the
LAN/WLAN whenever they are switched on. The DHCP server also puts
the hostname, supplied by the client DHCP request, in the local DNS
(Domain Name System/Service) proxy.
The DNS proxy contains a small database of local host names and
addresses supplied by client DHCP requests. In addition it also caches
requests to remote DNS servers.
The following configuration options are displayed in the “DHCP server”
section on the
LAN
page:

Description
Enable DHCP server
Select this checkbox to enable the DHCP
server.
Note:
If you already have a DHCP server on
your network, you should disable this feature in
the Ericsson W3x.
IP address range
from:
IP address range to:
The IP addresses that can be assigned to
LAN/WLAN clients are collected from a
predefined range of available IP addresses.
The preconfigured range – from 92.168.1.2 to
192.168.1.100 is suitable for most local
networks.
Lease Time [sec]:
The DHCP server uses the concept of a
“lease”, that is the amount of time that a given
IP address will be valid for a specific device. If
the lease time expires and the device is still
connected, the lease is automatically renewed.
The preconfigured lease time is 7200 seconds
(2 hours) and a valid value must be within the
range 60 and 2147483647 seconds.
Note:
If you want to configure a connected device with a static IP
address, make sure that the address is outside the DHCP server IP
address range.
Before changing any of the DHCP server settings, read the following:
•
The DHCP server IP address range has to be on the same subnet as
the LAN IP address on the Ericsson W3x.
•
The DHCP server IP address range must not include the LAN IP
address on the Ericsson W3x.
•
If port forwarding rules have been created, those settings have to be
removed before changing the DHCP server IP address range. For
more information, see section 3.7.3 –
Port Forwarding
.
To change the DHCP server settings, type the new values in the
corresponding fields and click
Apply
to save the settings.

Leases
When there are clients connected to the Ericsson W3x that have been
assigned IP addresses from the DHCP server they are presented in the
“DHCP Server” section as in the example below:
Figure 33 - DHCP server leases
If not, the text ”There are no leases at this time” is displayed.

LAN Port Status
The “LAN PORT STATUS” section on the
LAN
page shows the link status
of each Ethernet LAN port (
Ethernet

) on the Ericsson W3x.
Figure 34 - LAN Port Status
The status for each port is either green (Up) when a device is connected to
the port or red (Down) when no device is connected.
