			•	DL_SYN: The WiMAX Device is unable to conn ct to a bas station.
			•	RANGING: the WiMAX Device and the bas					station ar transmitting
				and receiving information about the istanc					betw n th m.
				Ranging allows the WiMAX Device to use a lower transmission power
				level when communicating with a nearby base station, and a higher
				transmission power level when commun cating with a distant base
				station.

				the base station. Traffic can n w flow between the WiMAX Device
				and the base stati n.
			• IDLE: the WiMAX Device is in power saving mode, but can connect
				when a base station alerts it that there is traffic waiting.

		Bandwidth	This field shows the size of the bandwidth step the WiMAX Device uses
			to connect to a base station in megahertz (MHz).
					C
		CINR mean	This field shows the average Carrier to Interference plus Noise Ratio of
			the curre t connection. This value is an indication of overall radio signal
			qualit . A higher value indicates a higher signal quality, and a lower
			valueyi dicates a lower signal quality.
		CINR devi tion	This field shows the amount of change in the CINR level. This value is
			n indication of radio signal stability. A lower number indicates a more
			st	ble signal, and a higher number indicates a less stable signal.
		RSSI	This field shows the Received Signal Strength Indication. This value is a
			measurement of overall radio signal strength. A higher RSSI level
			indicates a stronger signal, and a lower RSSI level indicates a weaker
			signal.
		pan
			A strong signal does not necessarily indicate a good signal: a strong
			signal may have a low signal-to-noise ratio (SNR).
		UL Data Rate	This field shows the number of data packets uploaded from the WiMAX
	m		Device to the base station each second.
o		DL Data Rate	This field shows the number of data packets downloaded to the WiMAX

		with an internal directional antenna. If y			u k w the location of the base station,
				on
		orient the front of the WiMAX Device (the side with the LEDs) towards the base

		station. If you do not know the locati n f the base station, experiment by moving
		the WiMAX Device while observing the Strength Indicator LEDs for an increase
		in received signal strength. The MAX-200HW2 and MAX-230HW2 do not have
		internal antennas.	y
	4	There might be a lot of traffic on the network. Look at the LEDs, and check Section
		pan
		1.2.1 on page 34. If the WiMAX Device is sending or receiving a lot of information,
		try closing some programs that use the Internet, especially peer-to-peer
		applications.
	5	Disconnect nd re-connect the power adapter to the WiMAX Device.
	6	If the roblem continues, contact the network administrator or vendor, or try one
	m
		of the advanced suggestions.

	The Internet connection disconnects.
C	1	Check your WiMAX link and signal strength using the WiMAX Link and Strength
		Indicator LEDs on the device.
	2	Contact your ISP if the problem persists.

22.4 Phone Calls and VoIP

The telephone port won’t work or the telephone lacks a dial tone.

		1 Check the telephone connections and telephone wire.			i
		2 Make sure you have the VOICE > Service Configuration > SIP Set ings				al
		screen properly configured (Chapter 12 on page 147).			t
	I can access the Internet, but cannot make VoIP calls.
		1 Make sure you have the VOICE > Service Con igurat on > SIP Settings
				iden
		screen properly configured (Chapter 12 o page 147).
			f
		2 The VoIP LED should come on. Make sure that y ur telephone is connected to the
		VoIP port (see the Quick Start Guide f r inf rmation on connecting telephone
		cables to the these ports).
		3 You can also check the VoIP status inonthe Status screen.
		4 If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you
		cannot make a call using speed dial, there may be something wrong with the SIP
			C
		server. Contact your VoIP service provider.
		y
	Problems With Multiple SIP Accounts
		You can set u two SIP accounts on your WiMAX Device. By default your WiMAX
		Device uses SIP account 1 for outgoing calls, and it uses SIP accounts 1 and 2 for
		incoming calls. With this setting, you always use SIP account 1 for your outgoing
		callspanand you cannot distinguish which SIP account the calls are coming in
		through. If you want to control the use of different dialing plans for accounting
		purposes or other reasons, you need to configure your phone port in order to
		control which SIP account you are using when placing or receiving calls.

22.5 Reset the WiMAX Device to Its Factory Defaults

	If you reset the WiMAX Device, you lose all of the changes you have made. The
	WiMAX Device re-loads its default settings, and the password resets to 1234. You
	have to make all of your changes again.			i
	You will lose all of your changes when you push the Reset button.				al
				t
	To reset the WiMAX Device,
	1 Make sure the Power LED is on and not blinking.
	2 Press and hold the Reset button for five to ten seconds. Release the Reset button
			i
	when the Power LED begins to blink. The default setti gsdenhave been restored.
		f
	If the WiMAX Device restarts automatically, wait for the WiMAX Device to finish
	restarting, and log in to the web c nfigurator. The password is “1234”.
	If the WiMAX Device does not restart aut matically, disconnect and reconnect the
	WiMAX Device’s power. Then, follow the directions above again.

		Wireless security is vital to protect your wireless communications. Without i ,
		information transmitted over the wireless network would be accessible to a y
		networking device within range.			i
	User Authentication and Data Encryption
					f
		The WiMAX (IEEE 802.16) standard employs user authent cat on and encryption to
		ensure secured communication at all times.
		User authentication is the process of co		firmi	g a user’s identity and level of
		authorization. Data encryption is the pr		cess	f e codi g information so that it
			C
		cannot be read by anyone who does n t kn w the code.
		WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and
		CCMP (Counter Mode with ipher Blockonhaining Message Authentication Protocol)
		y
		for data encryption.
		pan
		WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows
		additional authe ticatio methods to be deployed with no changes to the base
		station or the mobile or subscriber stations.
	PKMv2
		PKMv2 is rocedure that allows authentication of a mobile or subscriber station
	m
		and negotiation of a public key to encrypt traffic between the MS/SS and the base
		station. PKMv2 uses standard EAP methods such as Transport Layer Security
o		(EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure communication.
		In cryptography, a ‘key’ is a piece of information, typically a string of random
C		numbers and letters, that can be used to ‘lock’ (encrypt) or ‘unlock’ (decrypt) a
		message. Public key encryption uses key pairs, which consist of a public (freely

available) key and a private (secret) key. The public key is used for encryption and the private key is used for decryption. You can decrypt a message only if you have the private key. Public key certificates (or ‘digital IDs’) allow users to verify each other’s identity.

In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password they both know. The key is not sent over

Sent by the RADIUS server to indicate that it has started or stopped accounting.

Appendix A WiMAX Security

RADIUS

RADIUS is based on a client-server model that supports authentication, authorization and accounting. The base station is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:

		• Authentication					i
		Determines the identity of the users.
		• Authorization
								al
		Determines the network services available to authenticated users oncetthey are
		connected to the network.
		• Accounting
		Keeps track of the client’s network activity.
		RADIUS is a simple package exchange in which your base station acts as a
		message relay between the MS/SS and the network RADIUS server.
						i
	Types of RADIUS Messages						den
					f
		The following types of RADIUS messages are excha					ged between the base station
		and the RADIUS server for user authenticati n:
		• Access-Request
		Sent by an base station requesting authentication.
		• Access-Reject		on
		Sent by a RADIUS server rejecting access.
				C
		• Access-Accept
		Sent by a RADIUS server allowing access.
			y
		• Access-Ch lle ge
		Sent by RADIUS server requesting more information in order to allow access.
		The b se st tion sends a proper response from the user and then sends another
		Access-Request message.
		The following types of RADIUS messages are exchanged between the base station
		and the RADIUS server for user accounting:
