![Chapter 2 Wireless TutorialZyXEL NBG-334SH User’s Guide362.3.1 Connecting to a Wireless LANThe following sections show you how to join a wireless network using the ZyXEL utility, as in the following diagram. The wireless client is labeled C and the access point is labeled AP.There are three ways to connect the client to an access point.• Configure nothing and leave the wireless client to automatically scan for and connect to any available network that has no wireless security configured.• Manually connect to a network.• Configure a profile to have the wireless client automatically connect to a specific network or peer computer. This example illustrates how to manually connect your wireless client to an access point (AP) which is configured for WPA-PSK security and connected to the Internet. Before you connect to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this example, the SSID is “SSID_Example3” and the pre-shared key is “ThisismyWPA-PSKpre-sharedkey”. After you install the ZyXEL utility and then insert the wireless client, follow the steps below to connect to a network using the Site Survey screen. 1Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.2The wireless client automatically searches for available wireless networks. Click Scan if you want to search again. If no entry displays in the Available Network List, that means there is no wireless network available within range. Make sure the AP or peer computer is turned on or move the wireless client closer to the AP or peer computer.3When you try to connect to an AP with security configured, a window will pop up prompting you to specify the security settings. Enter the pre-shared key and leave the encryption type at the default setting.Use the Next button to move on to the next screen. You can use the Back button at any time to return to the previous screen, or the Exit button to return to the Site Survey screen.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-36.png)

This enables the service provider to easily create and offer new IP services for specific users.Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber’s site.By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.Refer to the appendix for more information on PPPoE.Figure 33 Wizard Step 3: PPPoE ConnectionThe following table describes the labels in this screen.4.4.3 PPTP ConnectionPoint-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks.PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such as the Internet.Refer to the appendix for more information on PPTP.Table 13 Wizard Step 3: PPPoE ConnectionLABEL DESCRIPTIONISP Parameter for Internet AccessConnection Type Select the PPP over Ethernet option for a dial-up connection.Service Name Type the name of your service provider.User Name Type the user name given to you by your ISP.

![Chapter 4 Connection WizardZyXEL NBG-334SH User’s Guide 65You 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. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.4.4.6 IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number.Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your ZyXEL Device, but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your ZyXEL Device will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the ZyXEL Device unless you are instructed to do otherwise.4.4.7 DNS Server Address AssignmentUse DNS (Domain Name System) 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 ZyXEL Device can get the DNS server addresses in the following ways.1The 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, enter them in the DNS Server fields in the Wizard and/or WAN > Internet Connection screen.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-65.png)

![ZyXEL NBG-334SH User’s Guide 73CHAPTER 5 Wireless LANThis chapter discusses how to configure the wireless network settings in your ZyXEL Device. See the appendices for more detailed information about wireless networks.5.1 Wireless Network OverviewThe following figure provides an example of a wireless network.Figure 41 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your ZyXEL Device is the AP.Every wireless network must follow these basic guidelines.• Every wireless client in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.• If two wireless networks overlap, they should use different channels.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-73.png)
![Chapter 5 Wireless LANZyXEL NBG-334SH User’s Guide74• Every wireless client 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.5.2 Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.5.2.1 SSIDNormally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP 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 devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.5.2.2 MAC Address FilterEvery wireless client 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 wireless client, see the appropriate User’s Guide or other documentation.You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.5.2.3 User AuthenticationYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.For wireless networks, there are two typical places to store the user names and passwords for each user.• In the AP: this feature is called a local user database or a local database.• In a RADIUS server: this is a server used in businesses more than in homes.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.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-74.png)
![Chapter 5 Wireless LANZyXEL NBG-334SH User’s Guide 75If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users.Unauthorized 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.Local user databases also have an additional limitation that is explained in the next section.5.2.4 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.The types of encryption you can choose depend on the type of user authentication. (See Section 5.2.3 on page 74 for information about this.)For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK.Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network."It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly.It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database.Table 21 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No Security WPAStatic WEPWPA-PSKStrongest WPA2-PSK WPA2](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-75.png)
![Chapter 5 Wireless LANZyXEL NBG-334SH User’s Guide76When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA Compatible option in the ZyXEL Device.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key.5.3 Quality of ServiceThis section discusses the Quality of Service (QoS) features available on the ZyXEL Device.5.3.1 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 delivery requirements. 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 tag 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 (delay) and jitter (variations in delay).5.3.1.1 WMM QoS PrioritiesThe following table describes the WMM QoS priority levels that the ZyXEL Device uses.Table 22 WMM QoS PrioritiesPRIORITY LEVEL DESCRIPTIONvoice(WMM_VOICE)Typically used for traffic that is especially sensitive to jitter. Use this priority to reduce latency for improved voice quality.video(WMM_VIDEO)Typically used for traffic which has some tolerance for jitter but needs to be prioritized over other data traffic.best effort(WMM_BEST_EFFORT)Typically used for traffic from applications or devices that lack QoS capabilities. Use best effort priority for traffic that is less sensitive to latency, but is affected by long delays, such as Internet surfing.background(WMM_BACKGROUND)This is typically used for non-critical traffic such as bulk transfers and print jobs that are allowed but that should not affect other applications and users. Use background priority for applications that do not have strict latency and throughput requirements.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-76.png)

Choose Factory Default to select the factory assigned default MAC Address.Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to the rom file (ZyNOS configuration file). It will not change unless you change the setting or upload a different ROM file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.6.3 MulticastTraditionally, IP packets are transmitted in one of either 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. IGMP (Internet Group Multicast Protocol) 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.

PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE.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 ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task.

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. The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the ZyXEL Device queries all directly connected networks to gather group membership. After that, the ZyXEL Device periodically updates this information. IP multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in the web configurator (LAN; WA N ). Select None to disable IP multicasting on these interfaces.7.2.4 Any IPTraditionally, you must set the IP addresses and the subnet masks of a computer and the ZyXEL Device to be in the same subnet to allow the computer to access the Internet (through the ZyXEL Device). In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the ZyXEL Device.With the Any IP feature and NAT enabled, the ZyXEL Device allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply connect the computer to the ZyXEL Device and access the Internet.The following figure depicts a scenario where a computer is set to use a static private IP address in the corporate environment. In a residential house where a ZyXEL Device is installed, you can still use the computer to access the Internet without changing the network settings, even when the IP addresses of the computer and the ZyXEL Device are not in the same subnet.](https://usermanual.wiki/ZyXEL-Communications/NBG334SH1.users-manual-pt1/User-Guide-811556-Page-100.png)
