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

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.
