Method 1 PBC

Use this section to set up a WPS wireless network using Push Button

Configuration (PBC).

WPS

Click this button to add another WPS-enabled wireless device (within

wireless range of the LTE Device) to your wireless network. This button

may either be a physical button on the outside of device, or a menu button

similar to the

WPS button

Note: You must press the other wireless device's WPS button within two

minutes of pressing this button.

Method 2 PIN

Use this section to set up a WPS wireless network by entering the PIN

(Personal Identification Number) of the client into the LTE Device.

Enter the PIN of the device that you are setting up a WPS connection with

and click

to authenticate and add the wireless device to your

wireless network.

You can find the PIN either on the outside of the device, or by checking

the device's settings.

Note: You must also activate WPS on that device within two minutes to

have it present its PIN to the LTE Device.

5.7 Technical Reference

This section discusses wireless LANs in depth.

5.7.1 Wireless Security Overview

By their nature, radio communications are simple to intercept. For wireless data networks, this

means that anyone within range of a wireless network without security can not only read the

data passing over the airwaves, but also join the network. Once an unauthorized person has

access to the network, he or she can steal information or introduce malware (malicious software)

intended to compromise the network. For these reasons, a variety of security systems have been

developed to ensure that only authorized people can use a wireless data network, or understand

the data carried on it.

These security standards do two things. First, they authenticate. This means that only people

presenting the right credentials (often a username and password, or a "key" phrase) can access

the network. Second, they encrypt. This means that the information sent over the air is encoded.

Only people with the code key can understand the information, and only people who have been

authenticated are given the code key.

These security standards vary in effectiveness. Some can be broken, such as the old Wired

Equivalent Protocol (WEP). Using WEP is better than using no security at all, but it will not

keep a determined attacker out. Other security standards are secure in themselves but can be

broken if a user does not use them properly. For example, the WPA-PSK security standard is

very secure if you use a long key which is difficult for an attacker's software to guess - for

example, a twenty-letter long string of apparently random numbers and letters - but it is not very

secure if you use a short key which is very easy to guess - for example, a three-letter word from

the dictionary.

Because of the damage that can be done by a malicious attacker, it's not just people who have

sensitive information on their network who should use security. Everybody who uses any

wireless network should ensure that effective security is in place.

A good way to come up with effective security keys, passwords and so on is to use obscure

information that you personally will easily remember, and to enter it in a way that appears

random and does not include real words. For example, if your mother owns a 1970 Dodge

Challenger and her favorite movie is Vanishing Point (which you know was made in 1971) you

could use "70dodchal71vanpoi" as your security key.

The following sections introduce different types of wireless security you can set up in the

wireless network.

5.7.2.1 SSID

Normally, the LTE Device acts like a beacon and regularly broadcasts the SSID in the area. You

can hide the SSID instead, in which case the LTE Device does not broadcast the SSID. In

addition, you should change the default SSID to something that is difficult to guess.

This type of security is fairly weak, however, because there are ways for unauthorized wireless

devices to get the SSID. In addition, unauthorized wireless devices can still see the information

that is sent in the wireless network.

5.7.2.2 MAC Address Filter

Every device that can use a wireless network has a unique identification number, called a MAC

address.1 A MAC address is usually written using twelve hexadecimal characters2; for example,

00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless

network, see the device's User's Guide or other documentation.

You can use the MAC address filter to tell the LTE Device which devices are allowed or not

allowed to use the wireless network. If a device is allowed to use the wireless network, it still

has to have the correct information (SSID, channel, and security). If a device is not allowed to

use the wireless network, it does not matter if it has the correct information.

This type of security does not protect the information that is sent in the wireless network.

Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an

authorized device. Then, they can use that MAC address to use the wireless network.

Some wireless devices, such as scanners, can detect wireless networks but cannot use

wireless networks. These kinds of wireless devices might not have MAC addresses.

Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

5.7.2.3 User Authentication

Authentication is the process of verifying whether a wireless device is allowed to use the

wireless network. You can make every user log in to the wireless network before using it.

However, every device in the wireless network has to support IEEE 802.1x to do this.

For wireless networks, you can store the user names and passwords for each user in a RADIUS

server. This is a server used in businesses more than in homes. If you do not have a RADIUS

server, you cannot set up user names and passwords for your users.

Unauthorized wireless devices can still see the information that is sent in the wireless network,

even if they cannot use the wireless network. Furthermore, there are ways for unauthorized

wireless users to get a valid user name and password. Then, they can use that user name and

password to use the wireless network.

5.7.2.4 Encryption

Wireless networks can use encryption to protect the information that is sent in the wireless

network. Encryption is like a secret code. If you do not know the secret code, you cannot

understand the message.

The types of encryption you can choose depend on the type of authentication. (See Section

5.7.2 for information about this.)
