3.1
About APManager
APManager software allows users to view contents of all wireless network under
Windows system (e.g. how many Access Points there are in a WLAN). You can
use APManager to control a large number of IEEE 802.11b Access Points from a
single location. Further more, the Access Points are remotely updated through the
SNMP 3 automatically. All indicate a simpler management for your wireless LAN4.
APManager is easy to operate and clear to understand, please keep reading for
further detail.
3.2

APManager Main Window
Choose the short cut icon to launch APManager from start menu, or from desktop.
The Main Window looks like below:
This section will explain in details features appeared on the above window, you
might wish to skip this part to Quick Start to Wireless Networking.
Structure of the Wireless LANs
The tree structure on the left of the main window shows a list of Wireless Local
Area Network (WLANs) and the Access Points that belong to each WLAN. The
Sample image above demonstrate a single Access Point with hardware address
00:90:4b:08:05:4e which belongs to WLAN named ‘APManager 1’. Furthermore
the icons shows the relationship between WLANs and their associated Access
Points as well as their status.
You can use your mouse to click or drag individual access points to view Access
Point properties or move an Access Point to another WLAN ect. For further
understanding, please also refer to section on managing WLANs.
13
Remember to give your WLAN a name!
The name (or SSID) of the WLAN is used for identifying the WLAN. Mobile
wireless clients roam freely over Access Points that have the same ‘name’ or
SSID. (please refer to the graphic example above) In other words, the secuity
options for all Access Points under the same SSID are the same. Security options
can be managed through the WLAN security property sheet. For further
information, please also refer to section on Managing Security
Access Point and WLAN Security Property Sheet
Access Point tab and WLAN Security tab is on the right hand side of the main
window. The Acces Point property sheet is mainly used to select a radio channel
for each Access Point 5 . WLAN security property sheet allows security
maintenance in a wireless LAN environment.

4.1
Managing WLANs
A WLAN or 'Wireless Local Area Network' in APManager consists of a number
of Access Points with the same settings that together provide seamless access to
any wireless stations that are in reach of any of these Access Points.
Create a WLAN
Select the Edit/Insert Wireless LAN menu item to insert a new
WLAN into the list. Type the name (SSID) of the new WLAN.
Destroy a WLAN
Remove an empty WLAN by pressing Delete or selecting the
Edit/Clear menu item.
Rename a WLAN
Click on the label of the WLAN to change its name (SSID). Note
that client stations use the name to identify the WLAN.
You can move an Access Point from one WLAN to another by dragging it with
the mouse or by selecting from menu Edit/Cut followed by Edit/Paste.
There are two WLANs that have a special meaning in APManager. These are the
Unused Access Points and Disabled Access Points special WLANs.
Unused Access Points
APManager does not manage the Unused Access Points within the context of the
current document. In other words, these Access Points are ignored. You can view
some information about them (e.g. radio channel), but not modify any of their
properties. APManager does not change the settings of these Access Points when
16
File/Commit to Network is selected. This is useful when different people manage
different sets of Access Points.
Disabled Access Points
Access Points that are moved to this folder will be made inaccessible for any
client station as soon as they are updated.
17
4.2
Managing Access Points
Individual Access Points are identified by their hardware address (or MAC
address). To insert a new Access Point into the APManager document manually,
its hardware address must be known. You can search for Access Points in your
network automatically; see Searching for Access Points.
Insert an Access Point
Select the Edit/Insert Access Point menu item to insert a new Access
Point into the selected WLAN. APManager will ask for the hardware
address of the Access Point.
Disable an Access Point
Move an Access Point to the ‘Disabled’ special WLAN by pressing
Delete or selecting the Edit/Clear menu item. Access Points in this
special WLAN will not be accessible for any client station. 6
The Access Points are shown with one of the following icons.
On-line
The Access Point is accessible on-line.
Off-line
The Access Point is currently not accessible, or the IP address is not known.

4.4
Network Settings Dialog
Selecting the Edit/Network Settings menu item (or by clicking the corresponding
toolbar button (as shown above) pops up the Network Settings dialog. Use this
dialog to inform APManager about your network configuration. APManager
needs this information to be able to scan for Access Points.
Add your network addresses (subnets) by entering the correct information in the
Network address, mask and default gateway fields in the dialog, and clicking the
Set button for each network/subnet. To view the details of a particular network,
click on the Address field in the list on the left. Click the Remove button to delete
a network from the list.
If the computer on which APManager is running is connected to all your networks
directly, you can try Auto Add Local Networks to insert them in the list.
Note: if subnetting10 is used, the network addresses and masks column generated
by this function will not be correct and should be adjusted manually.

Searching for Access Points
APManager has an easy-to-use Access Point discovery function that simplifies the
administration of the Access Points in your network. You normally apply the
Search function in one of the following situations:
New Access Points have been added to the network
The IP address of one or more Access Points is no longer valid or known,
possibly because the DHCP or BOOTP server has assigned it a different IP
address. You may be informed of this fact because the Access Points will be
reported off-line by APManager.
You may wish to prevent this by adding reservations for the Access Points in your
DHCP server configuration.
Invoke the Search function by selecting the menu command Edit/Search Access
Points, or pressing the associated toolbar button shown above (left hand side).
While APManager is scanning the network, you may continue work on the
document. If necessary you can abort a scan by clicking on the Abort Search
button shown above (right hand side).
A progress indicator will be shown in the status bar.
21
4.6
Manually programming IP addresses
The preferred method of providing IP addresses for your Access Points is to
deploy a DHCP server in your network. If you do, the Access Points will acquire
an IP address automatically from this server.
If you do not have a DHCP server, it is still possible to set the IP address of your
Access Points from APManager.
1.
2.
3.
4.
5.
6.
Physically connect the Access Points and the computer on which you run
APManager to the same Ethernet segment.
Make sure there is no DHCP or BOOTP server running.
Switch the Access Points on.
Configure the network you want your Access Points to be part of. 11
Enter the hardware addresses of the Access Points by hand using the
Edit/Insert Access Point menu command or clicking the appropriate toolbar
button.
For each Access Point select the Edit/Set IP Address menu command and
enter the required IP address manually. As soon as you press Set IP, the
Access Point should acquire the designated IP address. Within a few seconds,
the network
on the Access Point should light up green.
Note that you may or may not be able to communicate with the Access Point,
depending on the validity of the IP address in the current Ethernet segment.
The Access Point will use the designated IP Address indefinitely, and will no
longer respond to DHCP messages. You can, however, revoke the IP address by
following steps 1 to 4 above, and then selecting the Clear IP button. The Access
Point will start to respond to DHCP messages as normal.
11
See Network Settings Dialog for details.
22
4.7
Updating Access Point Settings
After modifying the open APManager document you should update the Access
Points in your network with the new settings. This is done for all Access Points
simultaneously by selecting the File/Commit to Network menu command; or by
clicking the associated toolbar button. During the update the following Dialog is
displayed:
Within 10 seconds after the Access Point has been successfully updated it will
disconnect all client stations that are joined with it, and restart with the new
settings. While restarting it will show red LED for a short period of time.
Please make sure that you press ‘Close’ when finished, this is a procedure so that
APManager will update with the new settings.
23
4.8
More about Cells
Each Access Point in the network forms the centre of a cell, or BSS. The Cells
should overlap slightly to guarantee seamless wireless connectivity everywhere.
Nearby Access Points should preferably send and receive on different channels for
maximum throughput.
Creating a cell plan for your site can be complicated, and is usually done by experts
employing special measuring equipment.
Furthermore, the radio channels you may use depend on both the capabilities of the
PC-Cards you are deploying, as well as the regulations in your area. The following
table may be of help:

Attempting to manage incompatible IEEE 802.11b equipment with APManager
may lead to unexpected results.
24
5. Managing Security
Maintaining security in a wireless LAN environment is somewhat different from a
wired network, because the radio waves do not stop at your office walls.
Eavesdropping or unauthorized access from outside your building can be a serious
threat.
There are three types of activities involved:
Protecting your data while it is transferred from one station to another.
Encryption techniques will be necessary in most environments (Data
Privacy).
Control who can make use of the wireless network (Access Control).
Protecting your network configuration against tampering from both inside
and outside your organization (Secure Management).
Data Privacy
An Access Point supports two different data privacy algorithms: unencrypted data;
standardised IEEE 802.11b WEP (based on a 64 bit shared key).
Access Control
The IEEE 802.11b standard allows for Access Control rules based on the client
station hardware address, and is fully implemented by the Access point.
Secure Management
The primary protection against tampering for any SNMP agent is the Write
Community String (WCS), which functions as a password for network
management commands. The WCS is send over your network in plain text,
making it vulnerable to eavesdropping from within your organization. The WCS is
never sent over the radio, however.
If you want, you can lock your Access Points. After being locked they can no
longer be managed over SNMP. Press the pinhole Reset switch on the back-panel
of the Access Point to unlock the Access Point.
25
5.1
WLAN Security Properties Tab
WLAN Security Properties Tab is on the right hand side of the main window. Its
main function is to select the data privacy algorithm(s) you want to support in the
Access Points
Note: it does not matter if you selected a single Access Point or an entire WLAN
in the tree control (on the left hand side of the main window). The changes you
make to the Security Properties will affect all Access Points within the WLAN.
This behavior is required to maintain seamless roaming throughout the WLAN.
26
5.2
Managing Access Control
Within the IEEE 802.11b framework, Access Control is based on the hardware
address of the client stations. Per client you can select whether or not it will be
allowed access to your wireless network structure. On the WLAN Security tab,
check the Use Access Control box to enable Access Control. If this box is not
checked, any client station can associate with your network.
Click the Access Control Settings button on the WLAN Security tab to pop up the
Access Control Dialog. Press Add to enter the client stations you want to grant
access.
A default rule determines whether unregistered stations can join. You can move
clients between Access Granted and Access Denied lists by clicking the >> and
<< buttons or pressing the left and right arrow keys.
Press Apply to confirm your changes and close the dialog.
27
5.3
IEEE 802.11b WEP Security
The IEEE 802.11b standard includes a Shared Key data privacy mechanism,
called Wired Equivalent Privacy
Features of WEP are:
Data encryption using a 64 bit shared key
No key distribution mechanism. The shared key (password) must be
distributed manually to all personnel and either be remembered or stored
somewhere on the hard disk.
Simple authentication of clients based on a challenge / response mechanism,
using the shared key and the hardware address.

wettings of the next Access Point. When you have set SSIDs and/or channels for
all Access Points on your network, clicking on Next will take you to the Network
Security Dialog box.
33
7.4
Build from Network - Network Security
To secure the network, it is possible to encrypt the data on the network with a
64-bit user defined WEP key. In fact, it is strongly recommended that WEP
security be enabled.
To enable WEP security, check the Enable WEP security box and enter a WEP
key in the Key field. Only clients and Access Points that share the same WEP key
are allowed to associate with each other.
WEP key can be any word or phrase of your choice. However we suggest that the
pass phrase you select is sixteen digits (for example, 22 7C 09 5D 43). This is
because pass phrase differ depending on the implementation of each user, and this
may cause disconnection between Wireless LAN adapters.
The Community String functions as a password for network management,
preventing unauthorized persons from changing the network security and Access
Point settings. It is strongly recommended that the Community String be changed
from the default (private).
After you set the WEP and Community String, click on Next. If more that one
Network ID (SSID) is defined on the network, the wizard will display this dialog
box again with the settings of the next SSID. When you have set WEP keys and
Community Strings for all SSIDs on your network, clicking Next will take you to
the Commit to Network dialog box.
