Adding an Access Point to a Cluster
To add an access point that is currently in standalone mode back into a cluster, do the
following.
1. Go to the Administration Web pages for the standalone access point. (See “Navigating
to an AP by Using its IP Address in a URL” in this manual.)
The Administration Web pages for the standalone access point are displayed.
2. Click the Basic Settings tab in the Administration pages for the standalone access
point.
The Basic Settings tab for a standalone access point indicates that the current mode is
standalone and provides a button for adding the access point to a cluster (group).
3. Click the
Join Cluster
button.
The access point is now a cluster member. Its Status (Mode) on the Cluster > Access
Points tab now indicates “cluster” instead of “standalone.”
The following table describes the access point settings and information display in
detail.
Modifying the Location Description
To make modifications to the location description:
1. Navigate to the
Basic Settings
tab.
2. Update the Location description in section 1 under “Review Description of this
Access Point.”
3. Click
Update
button to apply the changes.
Removing an Access Point from the Cluster
To remove an access point from the cluster, do the following.
1. Click the checkbox next to the access point so that the box is checked.
2. Click
Remove from Cluster
.
The change will be reflected under Status for that access point; the access point
will now show as
standalone
(instead of
cluster
).
Field Description
If you click on any of the Cluster tabs on the Administration pages for an access point
in standalone mode, you will be redirected to the Basic Settings page because Cluster
settings do not apply to standalone APs.
In some situations it is possible for the cluster to become out of sync. If after removing
an access point from the cluster, the AP list still reflects the deleted AP or shows
an incomplete display; refer to the information on Cluster Recovery in “Appendix B.
Troubleshooting” in this manual.

All clustered access points are shown on the Cluster > Access Points page. To navigate
to clustered access points, you can simply click on the IP address for a specific cluster
member shown in the list.
Navigating to an AP by Using its IP Address in a URL
You can also link to the Administration Web pages of a specific access point, by entering
the IP address for that access point as a URL directly into a Web browser address bar
in the following form:
http://
IPAddressOfAccessPoint
where
IPAddressOfAccessPoint
is the address of the particular access point you want
to monitor or configure.
For standalone access points, this is the only way to navigate to their configuration
information.
If you do not know the IP address for a standalone access point, use KickStart Wizard
on the CD-ROM to find all APs on the network and you should be able to derive which
ones are standalone by comparing KickStart findings with access points listed on the
Cluster > Access Points tab. The APs that KickStart Wizard finds that are not shown
on the this tab are probably standalone APs. (For more information on using KickStart,
see “Step 3. Run KickStart on the CD-ROM to find access points on the network” in
this manual.)
Navigating to Configuration Information for a Specific AP
and Managing Standalone APs
In general, the D-Link DWL-2210AP is designed for central management of
clustered
access points. For access points in a cluster, all access points in the cluster reflect the
same configuration. In this case, it does not matter which access point you actually
connect to for administration.
There may be situations, however, when you want to view or manage information on a
particular access point. For example, you might want to check status information such
as client associations or events for an access point. Or you might want to configure
and manage features on an access point that is running in
standalone
mode. In these
cases, you can navigate to the Administration Web interface for individual access points
by clicking the IP address links on the Access Points tab.
In some situations it is possible for the cluster to become out of sync. If after removing
an access point from the cluster, the AP list still reflects the deleted AP or shows
an incomplete display; refer to the information on Cluster Recovery in “Appendix B.
Troubleshooting” in this manual.

The D-Link DWL-2210AP includes user management capabilities for controlling client
access to access points.
User management and authentication must always be used in conjunction with
the following two security modes, which require use of a
RADIUS
server for user
authentication and management.
• IEEE 802.1x mode (see “IEEE 802.1x” in the Configuring Security section)
• WPA with RADIUS mode (see “WPA with RADIUS” in the Configuring Security
section)
You have the option of using either the internal RADIUS server embedded in the D-Link
DWL-2210AP or an external RADIUS server that you provide. If you use the embedded
RADIUS server, use this Administration Web page on the access point to set up and
manage user accounts. If you are using an external RADIUS server, you will need to set
up and manage user accounts on the Administrative interface for that server.
On the User Management page, you can create, edit, remove, and view client
user
accounts
. Each user account consists of a user name and password. The set of users
specified here represent approved
clients
that can log in and use one or more access
points to access local and possibly external networks via your wireless network.
The following topics are covered:
• Navigating to User Management for Clustered Access Points
• Viewing User Accounts
• Adding a User
• Editing a User Account
• Enabling and Disabling User Accounts
• Removing a User Account
Managing User Accounts
Users specified here are clients of the access point(s) who use the APs as a connectivity hub,
not administrators of the wireless network. Only those with the administrator username and
password and knowledge of the administration URL can log in as an administrator and view
or modify configuration settings.

Navigating to User Management for Clustered Access
Points
To set up or modify user accounts, click the
Cluster > Users
tab.
Viewing User Accounts
User accounts are shown at the top of the screen under “User Accounts” User name,
real name and status (enabled or disabled) are shown. You make modifications to an
existing user account by first selecting the checkbox next to a user name and then
choosing an action. (See “Editing a User Account” in this manual.)
Adding a User
To create a new user, do the following:
1. Under “Add a User,” provide information in the following fields.
Fields
Description
Username
Provide a user name.
User names are alphanumeric strings of up to 256 characters.
Do not use special characters or spaces.

Real Name
For information purposes, provide the user’s full name.
There is a 256 character limit on real names.
Password
Specify a password for this user.
Passwords are alphanumeric strings of up to 256 characters.
Do not use special characters or spaces.

2. When you have filled in the fields, click
Add Account
to add the account.
The new user is then displayed in the “User Accounts.” The user account is
enabled
by
default when you first create it.
.
Editing a User Account
Once you have created a user account, it is displayed under “User Accounts” at the top of
the
User Management
Administration Web page. To make modifications to an existing user
account, first click the checkbox next to the user name so that the box is checked.
A user account must be enabled for
the user to log on as a client and use
the access point.
You can
enable
or
disable
any
user account. With this feature,
you can maintain a set of user
accounts and authorize or prevent
users from accessing the network
without having to remove or recreate
Then, choose an action such Edit, Enable, Disable, or Remove.
Enabling and Disabling User Accounts
A limit of 100 user accounts per access point is imposed by the Administration
user interface. Network usage may impose a more practical limit, depending upon
the demand from each user
