Introduc ing the XMG
1.2 Wa ys to Ma na g e the XMG
Use any of the following methods to manage the XMG.
• Web Configurator. This is recommended for everyday management of the XMG using a (supported) web browser.
1.3 G o o d Ha b its fo r Ma na g ing the XMG
Do the following things regularly to make the XMG more secure and to manage the XMG more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the XMG to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the XMG. You could simply restore your last configuration.
1.4 A pp lic a tio ns fo r the XMG
Here are some example uses for which the XMG is well suited.

Computers can connect to the XMG’s LAN ports (or wirelessly).
You can also configure IP filtering on the XMG for secure Internet access. When the IP filter is on, all incoming traffic from the Internet to your network is blocked by default unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files.
1.4.1.1 DSL
Your XMG provides shared Internet access by connecting the DSL port to the DSL or MO DEM jack on a splitter or your telephone jack. You can have multiple WAN services over one ADSL or VDSL. The XMG cannot work in ADSL and VDSL mode at the same time.
Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you configure in
the XMG. Refer to
Figure 1 XMG’s Internet Access Application
Chapter 1 Introducing the XMG
Section 6.2 on page 65 for the Ne two rk Se tting > Broadb a nd screen.
1.4.1.2 Ethe rne t WAN
If you prefer not to use a DSL line and you have another broadband modem or router (such as ADSL) available, you can convert LAN port number four as a WAN port using the Ne two rk Se tting > Bro ad b a nd
> Etherne t WAN screen and then connect the LAN port to the broadband modem or router. This way,
you can access the Internet via an Ethernet connection and still use the QoS, Firewall and parental control functions on the XMG.

1.4.1.3 SFP
If you prefer not to use the Ethernet or DSL line, your XMG also provides shared Internet access by connecting the Small Form-Factor Pluggable (SFP) transceiver. SFP is also known as Fiber Optics interface. The Gigabit Ethernet (GbE) WAN with SFP is a dual-personality design (GbE + Fiber) which enables increased bandwidth and extended coverage. The XMG supports multiple VLANs over the SFP WAN interface for triple play. To connect the SFP port use a Fiber Optic Module, also known as a mini­GBIC transceiver, to a Switch or Router.
Chapter 1 Introducing the XMG
Figure 3 XMG’s Internet Access Application: Ethernet WAN
Note: You can only have Internet access through one of the ports (DSL, Ethernet or SFP) at a
time. Your XMG has WAN priority, and if you connect all ports simultaneously to a successful internet access, only one WAN port interface will be active. The XMG will prioritize SFP, then Ethernet, and last DSL.
1.4.2 XMG ’s USB Sup p o rt
The USB port of the XMG is used for file-sharing and media server.
File Sha ring
Use the built-in USB 2.0 port to share files on a USB memory stick or a USB hard drive (B). You can connect one USB hard drive to the XMG at a time. Use FTP to access the files on the USB device.

This section shows you how to set up a wireless network using WPS. It uses the XMG as the AP and Zyxel NWD210N as the wireless client which connects to the notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or
PCMCIA card).
There are two WPS methods to set up the wireless client settings:
Push Button C onfig ura tion (PBC ) - simply press a button. This is the easier of the two methods.
PIN Config ura tio n - configure a Personal Identification Number (PIN) on the XMG. A wireless client must also use the same PIN in order to download the wireless network settings from the XMG.
Push Butto n Config ura tio n (PBC )
1 Make sure that your XMG is turned on and your notebook is within the cover range of the wireless signal.
2 Make sure that you have installed the wireless client driver and utility in your notebook.

In the following figure, router R is connected to the XMG’s LAN. R connects to two networks, N1 (192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1 network) to computer B (in N2 network), the traffic is sent to the XMG’s WAN default gateway by default. In this case, B will never receive the traffic.
You need to specify a static routing rule on the XMG to specify R as the router in charge of forwarding traffic to N2. In this case, the XMG routes traffic from A to R and then R routes the traffic to B.
This tutorial uses the following example IP settings:

Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic because your task includes sending urgent updates to clients at least twice every hour. You also upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your colleagues use the Internet for research, as well as chat applications for communicating with other branch offices.
In the following figure, your Internet connection has an upstream transmission bandwidth of 10,000 kbps. For this example, you want to configure QoS so that e-mail traffic gets the highest priority with at least 5,000 kbps. You can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic going to the WAN interface, so that e-mail traffic would not get delayed when there is network congestion.
• Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for example) of your computer and map it to queue 7.
Note: QoS is applied to traffic flowing out of the XMG.
Traffic that does not match this class is assigned a priority queue based on the internal QoS mapping table on the XMG.

WA N IP Ad d re ss
The WAN IP address is an IP address for the XMG, which makes it accessible from an outside network. It is used by the XMG to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the XMG tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es).
ATM
Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit (VC) between Finding Out More
PTM
Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM, packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed to provide a low-overhead, transparent way of transporting packets over DSL links, as an alternative to ATM.
IPv6 Intro duc tio n
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10 can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment (6RD).

IP addresses. The XMG

Chapter 6 Broadband
IPv6 Add re ssing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So
2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can only appear once in an IPv6 address. So
2001:0db8:0000:0000:1a2f:0000:0000:0015 can be written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015, 2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
IPv6 Pre fix a nd Pre fix Le ng th
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6 prefix length specifies how many most significant bits (start from the left) in the address compose the network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
IPv6 Subne t Ma sking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
IPv6 Ra pid De p loym e nt
Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When the XMG has an IPv4 WAN address and you set IPv4/ IPv6 Mo de to IPv4 O nly, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The XMG generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISP’s Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local network can also use IPv4 services. The XMG uses it’s configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.

The XMG tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP’s Address Family Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also use IPv6 services. The XMG uses it’s configured IPv6 WAN IP to route IPv6 traffic to the IPv6 Internet.

Select the method of multiplexing used by your ISP from the drop-down list box. Choices are:
LLC / SNAP-BRIDGING: In LCC encapsulation, bridged PDUs are encapsulated by identifying the type of the bridged media in the SNAP header. This is available only when you select IPoE or PPPo E in the Sele c t DSL Link Type field.
VC/ MUX: In VC multiplexing, each protocol is carried on a single ATM virtual circuit (VC). To transport multiple protocols, the XMG needs separate VCs. There is a binding between a VC and the type of the network protocol carried on the VC. This reduces payload overhead since there is no need to carry protocol information in each Protocol Data Unit (PDU) payload.
LLC / ENC APSULATION: More than one protocol can be carried over the same VC. This is available only when you select PPPo A in the Encap sulation field.
LLC / SNAP-ROUTING : In LCC encapsulation, an IEEE 802.2 Logical Link Control (LLC) header is prefixed to each routed PDU to identify the PDUs. The LCC header can be followed by an IEEE 802.1a SubNetwork Attachment Point (SNAP) header. This is available only when you select IPoA in the Enc a psula tio n field.

Chapter 6 Broadband
IP ove r Ethe rne t
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet network, without using PPP encapsulation. They are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged Ethernet cells.
PPP ove r ATM (PPPo A)
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The XMG encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.

Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection.
For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example RADIUS).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the XMG (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the XMG does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
RFC 148 3
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to RFC 1483 for more detailed information.
Multiple xing
There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.
VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.
XMG3512-B10A User’s Guide
78
Chapter 6 Broadband
LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.
Tra ffic Sha ping
Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the maximum average rate at which cells can be sent over the virtual connection. SCR may not be greater than the PCR.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again.
If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 31 Example of Traffic Shaping
ATM Tra ffic C la sse s
These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification.
Constant Bit Rate (CBR)
Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being sent. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections that
XMG3512-B10A User’s Guide
79
Chapter 6 Broadband
continuously require a specific amount of bandwidth. A PCR is specified and if traffic exceeds this rate, cells may be dropped. Examples of connections that need CBR would be high-resolution video and voice.
Variable Bit Rate (VBR)
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-real time (VBR-nRT) connections.
The VBR-RT (real-time Variable Bit Rate) type is used with bursty connections that require closely controlled delay and delay variation. It also provides a fixed amount of bandwidth (a PCR is specified) but is only available when data is being sent. An example of an VBR-RT connection would be video conferencing. Video conferencing requires real-time data transfers and the bandwidth requirement varies in proportion to the video image's changing dynamics.
The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do not require closely controlled delay and delay variation. It is commonly used for "bursty" traffic typical on LANs. PCR and MBS define the burst levels, SCR defines the minimum level. An example of an VBR-nRT connection would be non-time sensitive data file transfers.
Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR doesn't guarantee any bandwidth and only delivers traffic when the network has spare bandwidth. An example application is background file transfer.
IP Add re ss Assig nm e nt
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and default gateway.
Intro d uc tio n to VLA Ns
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router.
In Multi-Tenant Unit (MTU) applications, VLAN is vital in providing isolation and security among the subscribers. When properly configured, VLAN prevents one subscriber from accessing the network resources of another on the same LAN, thus a user will not see the printers and hard disks of another user in the same building.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
XMG3512-B10A User’s Guide

Chapter 6 Broadband
Intro d uc tio n to IEEE 8 02.1Q Ta g g e d VLAN
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier), residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information), starts after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

Multic a st
IP packets are transmitted in either one of two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network ­not everybody and not just 1.
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to
239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group.
At start up, the XMG queries all directly connected networks to gather group membership. After that, the XMG periodically updates this information.
DNS Se rve r Ad d re ss A ssignm e nt
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it.
The XMG can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up.
If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
XMG3512-B10A User’s Guide
81
Chapter 6 Broadband
2 If your ISP dynamically assigns the DNS server IP addresses (along with the XMG’s WAN IP address), set
the DNS server fields to get the DNS server address from the ISP.
IPv6 Add re ssing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015, 2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
IPv6 Pre fix a nd Pre fix Le ng th
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6 prefix length specifies how many most significant bits (start from the left) in the address compose the network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.

“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and receive information over the airwowaves, wireless networking devices exchange information with one another. A wireless networking device is just like a radio that lets your computer exchange information with radios attached to other computers. Like walkie-talkies, most wireless networking devices operate at radio frequency bands that are open to the public and do not require a license to use. However, wireless networking is different from that of most traditional radio communications in that there a number of wireless networking standards available with different methods of data encryption.

7.2.2 Ba sic (WEP Enc ryp tio n)
WEP encryption scrambles the data transmitted between the wireless stations and the access points (AP) to keep network communications private. Both the wireless stations and the access points must use the same WEP key.
Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-
available software. It is strongly recommended that you use a more effective security mechanism. Use the strongest security mechanism that all the wireless devices in your network support. For example, use WPA-PSK or WPA2-PSK if all your wireless devices support it, or use WPA or WPA2 if your wireless devices support it and you have a RADIUS server. If your wireless devices support nothing stronger than WEP, use the highest encryption level available.
Your XMG allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can be enabled at any one time.
Note: WEP is not available when you set the wireless band to 5G Hz.
In order to configure and enable WEP encryption, click Ne two rk Se tting > Wire less to display the G e ne ra l screen, then select Ba sic as the security level.

7.2.3 More Se c ure (WPA(2)- PSK)
The WPA-PSK security mode provides both improved data encryption and user authentication over WEP. Using a Pre-Shared Key (PSK), both the XMG and the connecting client share a common password in order to validate the connection. This type of encryption, while robust, is not as strong as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer, more robust version of the WPA encryption standard. It offers slightly better security, although the use of PSK makes it less robust than it could be.

Select this option to extend the battery life of your mobile devices (especially useful for small devices that are running multimedia applications). The XMG goes to sleep mode to save power when it is not transmitting data. The AP buffers the packets sent to the XMG until the XMG "wakes up". The XMG wakes up periodically to check for incoming data.

Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or more wireless clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to one another in order to exchange information.

Chapter 7 Wireless
The following figure provides an example of a wireless network.
Figure 43 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B use the access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your XMG is the AP.
Every wireless network must follow these basic guidelines.
• Every device in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentifier.
• If two wireless networks overlap, they should use a different channel.
Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.
• Every device in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.
Ra d io C ha nne ls
In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use. For the purposes of wireless networking, these bands are divided into numerous channels. This allows a variety of networks to exist in the same place without interfering with one another. When you create a network, you must select a channel to use.
Since the available unlicensed spectrum varies from one country to another, the number of available channels also varies.

TERM DESCRIPTION
RTS/CTS Threshold In a wireless network which covers a large area, wireless devices are sometimes not
aware of each other’s presence. This may cause them to send information to the AP at the same time and result in information colliding and not getting through.
By setting this value lower than the default value, the wireless devices must sometimes get permission to send information to the XMG. The lower the value, the more often the devices must get permission.
If this value is greater than the fragmentation threshold value (see below), then wireless devices never have to get permission to send information to the XMG.
Preamble A preamble affects the timing in your wireless network. There are two preamble modes:

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

A small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy.

7.9.3 Wire le ss Se c urity O ve rview
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.
7.9.3.1 SSID
Normally, the XMG acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the XMG 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.
7.9.3.2 MAC A ddre ss Filter
Chapter 7 Wireless
Every device that can use a wireless network has a unique identification number, called a MAC address. 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 XMG 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.

A MAC address is usually written using twelve hexadecimal characters2; for example,
7.9.3.3 Use r A uthe ntic a tio n
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.
1. 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.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
