Access control within the wireless network
In this step you can specify which PCs will have wireless access to the Gigaset SE551
WLAN dsl/cable and hence to your LAN. The access control is based on the
MAC address
of the PCs' network adapters. You can enter the MAC addresses for the PCs manually or
select them from the list of PCs that are currently logged in.
The default setting for access control is disabled. This means that all PCs that use the
correct
SSID
can log in.
ì
Next to
MAC address filter
select the option
On
to activate the MAC filtering.
Entering MAC addresses manually
ì
Enter the MAC address of the network adapter. You will find this address on the bot-
tom of the device.
ì
Enter the name of the PC.
ì
Click on the
Add
button to add the entry to the list.
Selecting from the list of logged-in PCs
ì
Select the required PC from the
Known wireless clients
list. All PCs are displayed
that are currently logged in to the router with the correct SSID.
ì
Click on the
Add
button to add the selected PC to the list.

Saving settings
On the next screen you conclude the wizard and save the settings. You will be informed
of any security risks that still exist.
ì
Click on
Finish
to conclude the wizard.
The settings will now be active on your Gigaset SE551 WLAN dsl/cable.
Please remember:
If you activate MAC access control, you must at least enter the PC from which you
are configuring the Gigaset SE551 WLAN dsl/cable. Otherwise you will no longer
be able to access the user interface and a corresponding error message will be
shown.
If, by mistake, you have denied all PCs access to the Gigaset SE551 WLAN dsl/cable
you have two choices:
u
You can completely reset the Gigaset SE551 WLAN dsl/cable (see page 18).
u
You can connect a PC to the Gigaset SE551 WLAN dsl/cable using one of the
LAN connections (by cable). As MAC access control only applies to PCs that are
connected "wirelessly", you can use this PC to change the configuration.
Please remember:
You must now configure WEP or WPA key for your PC's wireless network adapter, if this
has been configured with other values. Once you have done this you can log in to your
Gigaset SE551 WLAN dsl/cable wirelessly again.
