MAC Filtering

The MAC Filtering screen enables you to allow specific devices to connect to MiFi 4620L's wireless

network. For example, if you put the MAC address for your Wi-Fi-enabled mobile phone and the

MAC address for your computer in the

Trusted Device List

, then only those devices can connect to

your device. The MAC Filtering screen has the following sections:

•

MAC Filter

(See

MAC Filter

on page 49.)

•

Trusted Device List

(See

Trusted Device List

on page 50.)

•

Connected Devices

(See

Connected Devices

on page 51.)

Trusted devices still need the correct network name (SSID) and network key (Wi-Fi passkey).

NOTE

The MAC address on the Windows operating system is called the

Physical Address

.

IMPORTANT

Do not enable MAC filtering unless you have added your own computer's MAC

address to the trusted device list. Otherwise you will be unable to access the device.

MAC Filter

The

Enable MAC Filter

checkbox enables or disables the MAC Filter feature.

•

When the feature is

enabled

(checked), you must add the MAC address for the device to

the Trusted Device List. If a device not in the list tries to connect to the MiFi 4620L wireless

network, the connection is blocked even if the device has the correct network name (SSID)

and network key (Wi-Fi passkey).

•

When the feature is

disabled

(un-checked), any device with the correct network name (SSID)

and network key (Wi-Fi passkey) can connect to the MiFi 4620L wireless network.

Find the MAC Address on a Computer

The Media Access Controller (MAC) Address is also known as a hardware or physical address for a

device (usually a network adapter). It consists of six pairs of numbers and letters (for example,

00-21-9B-1C-64-34).

You can view the MAC address for any device connected to the MiFi wireless network from the Wi-Fi

screen. (See

Wi-Fi Settings

on page 27.)

Tip!

You can cut and paste your computer's MAC address from the Wi-Fi Clients section of the Wi-Fi

screen.

If the computer is not connected to the MiFi wireless network, you can find the MAC address

directly. To find the MAC address, follow one of these steps:

•

On a Windows PC, the MAC address is the Physical Address. You can find the Physical Address

by running

ipconfig /all

from the cmd window.

»

To run

ipconfig/all

, select

Start > All Programs

(or

Programs

) >

Accessories

>

Command

Prompt

to open the Command Prompt window. Then type

ipconfig/all

and press the

Return

or

Enter

key.

•

On a Mac, the MAC address is the AirPort ID.

»

To find the AirPort ID, open the

Apple

Menu

>

System Preferences

>

Network

. In the list, click

AirPort

. Click

Advanced

. A sheet opens. Click the

AirPort

tab. The AirPort ID is at the bottom of the

sheet.

IMPORTANT

Windows only: Make sure you get the MAC address for the wireless network

adapter and not the Ethernet controller (NIC), if the computer has both.
