Refer to Appendix E on page 153 for further readings on Wireless LAN.6.5.1 WMM QoSWMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless networks. It controls WLAN transmission priority on packets to be transmitted over the wireless network.WMM QoS prioritizes wireless traffic according to the delivery requirements of the individual and applications. WMM QoS is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks.On APs without WMM QoS, all traffic streams are given the same access priority to the wireless network. If the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity, then the new traffic stream reduces the throughput of the other traffic streams.The ZyXEL Device uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q or DSCP information in each packet’s header. The ZyXEL Device automatically determines the priority to use for an individual traffic stream. This prevents reductions in data transmission for applications that are sensitive to latency and jitter (variations in delay).6.5.2 Spanning Tree Protocol (STP)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a bridge to interact with other STP-compliant bridges in your network to ensure that only one route exists between any two stations on the network.6.5.2.1 Rapid STPThe ZyXEL Device uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allow faster convergence of the spanning tree (while also being backwards compatible with STP-only aware bridges). Using RSTP topology change information does not have to propagate to the root bridge and unwanted learned addresses are flushed from the filtering database. In RSTP, the port states are Discarding, Learning, and Forwarding.6.5.2.2 STP TerminologyThe root bridge is the base of the spanning tree; it is the bridge with the lowest identifier value (MAC address).](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-1.png)
![Chapter 6 Wireless Settings ScreenZyXEL NWA-1100 User’s Guide72Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned according to the speed of the link to which a port is attached. The slower the media, the higher the cost - see the following table.On each bridge, the root port is the port through which this bridge communicates with the root. It is the port on this switch with the lowest path cost to the root (the root path cost). If there is no root port, then this bridge has been accepted as the root bridge of the spanning tree network.For each LAN segment, a designated bridge is selected. This bridge has the lowest cost to the root among the bridges connected to the LAN. 6.5.2.3 How STP WorksAfter a bridge determines the lowest cost-spanning tree with STP, it enables the root port and the ports that are the designated ports for connected LANs, and disables all other ports that participate in STP. Network packets are therefore only forwarded between enabled ports, eliminating any possible network loops.STP-aware bridges exchange Bridge Protocol Data Units (BPDUs) periodically. When the bridged LAN topology changes, a new spanning tree is constructed.Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello BPDU after a predefined interval (Max Age), the bridge assumes that the link to the root bridge is down. This bridge then initiates negotiations with other bridges to reconfigure the network to re-establish a valid network topology.6.5.2.4 STP Port StatesSTP assigns five port states (see next table) to eliminate packet looping. A bridge port is not allowed to go directly from blocking state to forwarding state so as to eliminate transient loops.

You might disable this kind of communication to enhance security within your wireless network.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 ZyXEL Device. 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 ZyXEL Device.Preamble A preamble affects the timing in your wireless network. There are two preamble modes: long and short. If a device uses a different preamble mode than the ZyXEL Device does, it cannot communicate with the ZyXEL Device.Fragmentation ThresholdA small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy.Roaming If you have two or more ZyXEL Devices (or other wireless access points) on your wireless network, you can enable this option so that wireless devices can change locations without having to log in again. This is useful for devices, such as notebooks, that move around a lot.Antenna An antenna couples Radio Frequency (RF) signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN.](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-3.png)

![ZyXEL NWA-1100 User’s Guide 75CHAPTER 7 Wireless Security Screen7.1 OverviewThis chapter describes how to use the Wireless Security screen. This screen allows you to configure the security mode for your ZyXEL Device.Wireless security is vital to your network. It protects communications between wireless stations, access points and the wired network. Figure 31 Securing the Wireless NetworkIn the figure above, the ZyXEL Device checks the identity of devices before giving them access to the network. In this scenario, Computer A is denied access to the network, while Computer B is granted connectivity.The ZyXEL Device secure communications via data encryption, wireless client authentication and MAC address filtering. It can also hide its identity in the network.7.2 What You Can Do in the Wireless Security ScreenUse the Wireless > Security screen (see Section 7.4 on page 77) to choose the security mode for your ZyXEL Device.](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-5.png)
![Chapter 7 Wireless Security ScreenZyXEL NWA-1100 User’s Guide767.3 What You Need To Know About Wireless SecurityUser AuthenticationAuthentication 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 they can use 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.The following table shows the relative effectiveness of wireless security methods:.The available security modes in your ZyXEL Device are as follows:•None. No data encryption.•WEP. Wired Equivalent Privacy (WEP) encryption scrambles the data transmitted between the wireless stations and the access points to keep network communications private.•802.1x-Only. This is a standard that extends the features of IEEE 802.11 to support extended authentication. It provides additional accounting and control features. This option does not support data encryption.•802.1x-Static64. This provides 802.1x-Only authentication with a static 64bit WEP key and an authentication server.•802.1x-Static128. This provides 802.1x-Only authentication with a static 128bit WEP key and an authentication server.•WPA. Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. •WPA2. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.•WPA2-MIX. This commands the ZyXEL Device to use either WPA2 or WPA depending on which security mode the wireless client uses.•WPA2-PSK. This adds a pre-shared key on top of WPA2 standard.Table 15 Wireless Security LevelsSECURITY LEVEL SECURITY TYPELeast S e c u r e Most SecureUnique SSID (Default)Unique SSID with Hide SSID EnabledMAC Address FilteringWEP EncryptionIEEE802.1x EAP with RADIUS Server AuthenticationWi-Fi Protected Access (WPA)WPA2](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-6.png)
![Chapter 7 Wireless Security ScreenZyXEL NWA-1100 User’s Guide 77•WPA2-PSK-MIX. This commands the ZyXEL Device to use either WPA-PSK or WPA2-PSK depending on which security mode the wireless client uses."In Bridge and Bridge + AP operating modes, the only available security modes are WEP and WPA2-PSK.PassphraseA passphrase functions like a password. In WEP security mode, it is further converted by the ZyXEL Device into a complicated string that is referred to as the “key”. This key is requested from all devices wishing to connect to a wireless network.PSKThe Pre-Shared Key (PSK) is a password shared by a wireless access point and a client during a previous secure connection. The key can then be used to establish a connection between the two parties.EncryptionWireless 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. Encryption is the process of converting data into unreadable text. This secures information in network communications. The intended recipient of the data can “unlock” it with a pre-assigned key, making the information readable only to him. The ZyXEL Device when used as a wireless client employs Temporal Key Integrity Protocol (TKIP) data encryption.EAPExtensible Authentication Protocol (EAP) is a protocol used by a wireless client, an access point and an authentication server to negotiate a connection. The EAP methods employed by the ZyXEL Device when in Wireless Client operating mode are Transport Layer Security (TLS), Protected Extensible Authentication Protocol (PEAP), Lightweight Extensible Authentication Protocol (LEAP) and Tunneled Transport Layer Security (TTLS). The authentication protocol may either be Microsoft Challenge Handshake Authentication Protocol Version 2 (MSCHAPv2) or Generic Token Card (GTC).Further information on these terms can be found in Appendix E on page 153. 7.4 The Security ScreenUse this screen to choose the security mode for your ZyXEL Device.

![ZyXEL NWA-1100 User’s Guide 89CHAPTER 8 RADIUS Screen8.1 OverviewThis chapter describes how you can use the Wireless > RADIUS screen.Remote Authentication Dial In User Service (RADIUS) is a protocol that can be used to manage user access to large networks. It is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. Figure 42 RADIUS Server SetupIn the figure above, wireless clients A and B are trying to access the Internet via the ZyXEL Device. The ZyXEL Device in turn queries the RADIUS server if the identity of clients A and U are allowed access to the Internet. In this scenario, only client U’s identity is verified by the RADIUS server and allowed access to the Internet. 8.2 What You Can Do in the RADIUS ScreenUse the Security > RADIUS screen (see Section 7.4.1 on page 78) if you want to authenticate wireless users using a RADIUS Server and/or Accounting Server.8.3 What You Need to Know About RADIUSThe RADIUS server handles the following tasks:•Authentication which determines the identity of the users.•Authorization which determines the network services available to authenticated users once they are connected to the network.Authentication](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-19.png)

If your networks are isolated from the Internet (only between your two branch offices, for instance) you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses."Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above.

FTPFile Transfer Protocol (FTP) allows you to upload or download a file or several files to and from a remote location using a client or the command console. WWWThe World Wide Web allows you to access files hosted in a remote server. For example, you can view text files (usually referred to as ‘pages’) using your web browser via HyperText Transfer Protocol (HTTP).SNMPSimple Network Management Protocol (SNMP) is a member of the TCP/IP protocol suite used for exchanging management information between network devices. Your ZyXEL Device supports SNMP agent functionality, which allows a manager station to manage and monitor the ZyXEL Device through the network. The ZyXEL Device supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation. ."SNMP is only available if TCP/IP is configured.](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-32.png)
![Chapter 11 Remote ManagementZyXEL NWA-1100 User’s Guide 103Figure 49 SNMP Management ModeAn SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the ZyXEL Device). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. SNMP allows a manager and agents to communicate for the purpose of accessing information such as packets received, node port status, etc.Remote Management LimitationsRemote management over LAN or WLAN will not work when:• You have disabled that service in one of the remote management screens.• The IP address in the Secured Client IP field does not match the client IP address. If it does not match, the ZyXEL Device will disconnect the session immediately.• You may only have one remote management session running at one time. The ZyXEL Device automatically disconnects a remote management session of lower priority when another remote management session of higher priority starts. The priorities for the different types of remote management sessions are as follows:1. Telnet2. HTTPSystem TimeoutThere is a default system management idle timeout of five minutes (three hundred seconds). The ZyXEL Device automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling.

Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:• Get - Allows the manager to retrieve an object variable from the agent. • GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. • Set - Allows the manager to set values for object variables within an agent. • Trap - Used by the agent to inform the manager of some events.11.8.2 Supported MIBsThe ZyXEL Device supports MIB II that is defined in RFC-1213 and RFC-1215 as well as the proprietary ZyXEL private MIB. The purpose of the MIBs is to let administrators collect statistical data and monitor status and performance.11.8.3 SNMP Traps SNMP traps are messages sent by the agents of each managed device to the SNMP manager.

![Chapter 12 Certificate ScreenZyXEL NWA-1100 User’s Guide 11312.5.1 Private-Public CertificatesWhen using public-key cryptology for authentication, each host has two keys. One key is public and can be made openly available. The other key is private and must be kept secure. These keys work like a handwritten signature (in fact, certificates are often referred to as “digital signatures”). Only you can write your signature exactly as it should look. When people know what your signature looks like, they can verify whether something was signed by you, or by someone else. In the same way, your private key “writes” your digital signature and your public key allows people to verify whether data was signed by you, or by someone else. This process works as follows.1Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). 2Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not. 3Tim uses his private key to sign the message and sends it to Jenny.4Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is from Tim, and that although other people may have been able to read the message, no-one can have altered it (because they cannot re-sign the message with Tim’s private key).5Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to verify the message.12.5.2 Certification AuthoritiesA Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the ZyXEL Device to generate certification requests that contain identifying information and public keys and then send the certification requests to a certification authority.12.5.3 Checking the Fingerprint of a Certificate on Your ComputerA certificate’s fingerprints are message digests calculated using the MD5 or SHA1 algorithms. The following procedure describes how to check a certificate’s fingerprint to verify that you have the actual certificate. 1Browse to where you have the certificate saved on your computer. 2Make sure that the certificate has a “.cer” or “.crt” file name extension.Figure 56 Certificates on Your Computer](https://usermanual.wiki/ZyXEL-Communications/NWA1100.Installation-guide-II/User-Guide-988472-Page-43.png)
