When you add a new wireless client to an existing network, there are certain
pieces of information you need to have. The range extender may provide some of this
information to the client automatically, but if it doesn’t, you
will have to enter it yourself.
When you install a wireless adapter in a computer running Windows,
it usually comes with a utility that is installed on the computer and
displays an icon in the taskbar’s notification area.
Windows XP also provides its own mechanism for managing wireless adapters.
One thing all wireless devices have in common is that they have some way to
configure the wireless connection.
Although there are many different wireless devices, they use almost identical
terms for the information they require to establish a wireless connection.

MAC filtering is denying only specified devices.
1. Network name (SSID)
The first thing a wireless client needs to know is the network name or SSID,
which is set on the range extender.
The network name of this range extender is USR9550.
Since the range extender is broadcasting its network name, you don’t have to
enter it into the wireless device’s utility. You should be able to perform a
“site survey” or “scan” and the utility will indicate that
it’s found the range extender’s network name.
The range extender is not broadcasting its network name, so you will need to enter it
into the wireless device’s utility. Most utilities are different, but
there is usually a mechanism for creating a “profile” and entering
the necessary information.
2. Security
In order for a wireless client to communicate with a range extender using security,
it must use the same method.
Security for wireless communication consists of an authentication method (which controls
which devices can connect to the range extender) and an encryption method (which prevents someone from
“reading” the data being sent between a wireless client and the range extender).
The range extender’s authentication method is .
The encryption method is
and the encryption key is .
The range extender’s authentication method is .
The encryption method is WEP and the encryption key is
.
You may also need to select the type of key, which is .
The range extender is insecure, so the client device may already be able to connect to it.
3. MAC Filtering
Since this range extender has MAC filtering enabled and is allowing only certain
wireless devices to connect, you need to ensure that the client device’s
MAC address is permitted to connect to the range extender.
One way to do this is to turn off MAC filtering and configure the client
device to connect to the range extender. After that’s completed, you can use
the range extender’s Allow Current Clients feature to
automatically add the new client to the list of allowed devices and re-enable MAC filtering.
Since this range extender has MAC filtering enabled and is denying certain wireless
devices the ability to connect, you need to ensure that the client device’s
MAC address is not in the list of devices to be denied.
A MAC address is a set of six bytes typically separated by colons or dashes or spaces.
(A byte consists of two hexadecimal digits—0-9 and A-F.)
For example: “.”
These are some ways you may be able to determine the client device’s MAC address:
The MAC address is typically displayed on the device itself or on the device’s packaging.
If the device is running Windows XP, 2000, or NT and you’re familiar with the command prompt,
you can use the “ipconfig /all” command to display the MAC address.
If the device is running Windows Me, 98, or 95 and you’re familiar with the command prompt,
you can use the “winipcfg” command to display the MAC address.
The device’s wireless configuration utility typically displays the MAC address somewhere.
You can configure MAC filtering on the Security page.
Troubleshooting
If a wireless device cannot connect, the wrong encryption method may be
selected or the key may be entered incorrectly.
Double-check the device’s wireless configuration utility to ensure
you’ve entered everything correctly.
Make sure the wireless device has “Infrastructure” selected as the network type.
You should also make certain that the range extender and client device are positioned so that their
transmissions can reach each other.
If possible, try to configure them when they are positioned next to each other.
Since this range extender has MAC filtering configured to allow only certain devices
to connect, the client device’s MAC address might not be in the list of
devices permitted to connect to the range extender.
You can configure MAC filtering on the Security page.
Since this range extender has MAC filtering configured to deny certain devices, the
client device’s MAC address might be in the list of devices to be denied.
