3.
DHCP Server
The DHCP server function makes setting up a network very easy by
assigning IP addresses to each computer on the network automatically.
The default setting is “On”. The DHCP server can be turned OFF if
necessary; however, in order to do so you must manually set a static
IP address for each computer on your network. To turn off the DHCP
server, select “Off” and click “Apply Changes”.
4.
IP Pool
The range of IP addresses set aside for dynamic assignment to the
computers on your network. The default is 2–100 (99 computers). If you
want to change this number, you can do so by entering a new starting
and ending IP address and clicking on “Apply Changes”. The DHCP server
can assign 100 IP addresses automatically. This means that you cannot
specify an IP address pool larger than 100 computers. For example,
starting at 50 means you have to end at 150 or lower so as not to
exceed the 100-client limit. The starting IP address must be lower in
number than the ending IP address.
5.
Lease Time
The length of time the DHCP server will reserve the IP address for
each computer. We recommend that you leave the lease time set to
“Forever”. The default setting is “Forever”, meaning that any time a
computer is assigned an IP address by the DHCP server, the IP address
will not change for that particular computer. Setting lease times
for shorter intervals such as one day or one hour frees IP addresses
after the specified period of time. This also means that a particular
computer’s IP address may change over time. If you have set any of the
other advanced features of the Router such as DMZ or client IP filters,
these are dependent on the IP address. For this reason, you will not
want the IP address to change.
6.
Local Domain Name
The default setting is “Ativa”. You can set a local domain name (network
name) for your network. It is not necessary to change this setting unless
you have a specific naming requirement. You can name the network
anything you want such as “MY NETWORK”.

Viewing the DHCP Client List Page
You can view a list of the computers (known as clients), which are connected
to your network. You are able to view the IP address
(1)
of the computer, the
host name
(2)
(if the computer has been assigned one), and the MAC address
(3)
of the computer’s network interface card (NIC). Pressing the “Refresh”
(4)
button will update the list. If there have been any changes, the list will
be updated.

Configuring the Wireless Network Settings
Clicking on the header of the “Wireless” tab will take you to the “Wireless”
header page. From this page, the Router’s wireless radio can be enabled or
disabled (the default setting is enabled). Under the “Wireless” tab, there are
links that allow you to make changes to the wireless network settings.

Changing the Wireless Network Name (SSID)
To identify your wireless network, a name called the SSID (Service Set
Identifier) is used. The default SSID of the Router is “Ativa54g”. You can
change this to anything you want to or you can leave it unchanged. If
there are other wireless networks operating in your area, you will want
to make sure that your SSID is unique (does not match that of another
wireless network in the area). To change the SSID, type in the SSID that
you want to use in the “SSID” field
(1)
and click “Apply Changes”
(2)
. The
change is immediate. If you make a change to the SSID, you may also need
to reconfigure your wireless-equipped computers to connect to your new
network name. Refer to your wireless network adapter’s documentation for
information on making this change.

Using the Wireless Mode Switch
Your Router can operate in three different wireless modes:
“g and b”, “g only”, and “b only”. The different modes are
explained on the next page.

g and b Mode
In this mode, the Router is compatible with 802.11b and 802.11g wireless
clients simultaneously. This is the factory default mode and ensures
successful operation with all Wi-Fi-compatible devices. If you have a mix
of 802.11b and 802.11g clients in your network, we recommend setting the
Router to g and b mode. This setting should only be changed if you have a
specific reason to do so.
g only Mode
g only mode works with 802.11g clients only. This mode is recommended
only if you want to prevent 802.11b clients from accessing your network. To
switch modes, select the desired mode from the “Wireless Mode” drop-down
box. Then, click “Apply Changes”.
b only Mode
We recommend you DO NOT use this mode unless you have a very specific
reason to do so. This mode exists only to solve unique problems that
may occur with some 802.11b client adapters and is NOT necessary for
interoperability of 802.11g and 802.11b standards.
When to use b only Mode
In some cases, older 802.11b clients may not be compatible with 802.11g
wireless. These adapters tend to be of inferior design and may use older
drivers or technology. Switching to this mode can solve problems that
sometimes occur with these clients. If you suspect that you are using a
client adapter that falls into this category of adapters, first check with the
adapter vendor to see if there is a driver update. If there is no driver update
available, switching to b only mode may fix your problem.
Please note that
switching to b only mode will decrease 802.11g performance.
Changing the Wireless Channel
There are a number of operating channels you can choose from. In the
United States and Australia, there are 11 channels. In the United Kingdom
and most of Europe, there are 13 channels. In a small number of other
countries, there are other channel requirements. Your Router is configured
to operate on the proper channels for the country you reside in. The default
channel is 11 (unless you are in a country that does not allow channel 11).
The channel can be changed if needed. If there are other wireless networks
operating in your area, your network should be set to operate on a channel
that is different than the other wireless networks. For best performance,
use a channel that is at least five channels away from the other wireless
network. For instance, if another network is operating on channel 11, then
set your network to channel 6 or below. To change the channel, select the
channel from the drop-down list. Click “Apply Changes”. The change
is immediate
