Use File Transfer Protocol for firmware upgrades and configuration backup/restore.1.3  Good Habits for Managing the NBG318SDo the following things regularly to make the NBG318S more secure and to manage the NBG318S 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 NBG318S to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG318S. You could simply restore your last configuration.1.4  LEDsFigure 4   Front PanelThe following table describes the LEDs.Table 1   Front Panel LEDsLED ICON COLOR STATUS DESCRIPTIONPOWER Green On The NBG318S is receiving power and functioning properly.

NBG318S User’s Guide 35CHAPTER  2 Wireless TutorialThis chapter gives you examples of how to set up an access point and wireless client for wireless communication using the following parameters. The wireless clients can access the Internet through an AP wirelessly.2.1  Example ParametersAn access point (AP) or wireless router is referred to as an “AP” and a computer with a wireless network card or USB/PCI adapter is referred to as a “wireless client” here.We use the M-302 utility screens as an example for the wireless client. The screens may vary for different models.2.2  Configuring the APFlow the steps below to configure the wireless settings on your AP.1Open the Wireless LAN > General screen in the AP’s web configurator.SSID SSID_Example3Channel 6Security  WPA-PSK(Pre-Shared Key: ThisismyWPA-PSKpre-sharedkey)802.11 mode IEEE 802.11b/g
Chapter 2 Wireless TutorialNBG318S User’s Guide36Figure 5   Network > Wireless LAN > General2Make sure the Enable Wireless LAN check box is selected.3Enter SSID_Example3 as the SSID and select a channel.4Set security mode to WPA-PSK and enter ThisismyWPA-PSKpre-sharedkey in the Pre-Shared Key field. Click Apply.5Open the Status screen.Verify your wireless and wireless security settings under Device Information and check if the WLAN connection is up under Interface Status.Figure 6   Network > Wireless LAN > General
 Chapter 2 Wireless TutorialNBG318S User’s Guide 376Click the WLAN Station Status hyperlink in the AP’s Status screen. You can see if any wireless client has connected to the AP.Figure 7   AP: Status: WLAN Station Status2.3  Configuring the Wireless ClientThis section describes how to connect the wireless client to a network.2.3.1  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 labelled C and the access point is labelled 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.
Chapter 2 Wireless TutorialNBG318S User’s Guide381Open 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.Figure 8   ZyXEL Utility: Security Settings 4The Confirm Save window appears. Check your settings and click Save to continue.
 Chapter 2 Wireless TutorialNBG318S User’s Guide 39Figure 9   ZyXEL Utility: Confirm Save5The ZyXEL utility returns to the Link Info screen while it connects to the wireless network using your settings. When the wireless link is established, the ZyXEL utility icon in the system tray turns green and the Link Info screen displays details of the active connection. Check the network information in the Link Info screen to verify that you have successfully connected to the selected network. If the wireless client is not connected to a network, the fields in this screen remain blank. Figure 10   ZyXEL Utility: Link Info 6Open your Internet browser and enter http://www.zyxel.com or the URL of any other web site in the address bar. If you are able to access the web site, your wireless connection is successfully configured. If you cannot access the web site, try changing the encryption type in the Security Settings screen, check the Troubleshooting section of this User's Guide or contact your network administrator.2.3.2  Creating and Using a ProfileA profile lets you automatically connect to the same wireless network every time you use the wireless client. You can also configure different profiles for different networks, for example if you connect a notebook computer to wireless networks at home and at work. This example illustrates how to set up a profile and connect the wireless client to an access point configured for WPA-PSK security. In this example, the SSID is “SSID_Example3”, the profile name is “PN_Example3” and the pre-shared key is “ThisismyWPA-PSKpre-sharedkey”. You have chosen the profile name “PN_Example3”.
Chapter 2 Wireless TutorialNBG318S User’s Guide401Open the ZyXEL utility and click the Profile tab to open the screen shown next. Click Add to configure a new profile.Figure 11   ZyXEL Utility: Profile2The Add New Profile screen appears. The wireless client automatically searches for available wireless networks, which are displayed in the Scan Info box. Click on Scan if you want to search again. You can also configure your profile for a wireless network that is not in the list.Figure 12   ZyXEL Utility: Add New Profile3Give the profile a descriptive name (of up to 32 printable ASCII characters). Select Infrastructure and either manually enter or select the AP's SSID in the Scan Info table and click Select.4Choose the same encryption method as the AP to which you want to connect (In this example, WPA-PSK).Figure 13   ZyXEL Utility: Profile Security
 Chapter 2 Wireless TutorialNBG318S User’s Guide 415This screen varies depending on the encryption method you selected in the previous screen. Enter the pre-shared key and leave the encryption type at the default setting.Figure 14   ZyXEL Utility: Profile Encryption6In the next screen, leave both boxes checked.Figure 15   Profile: Wireless Protocol Settings.7Verify the profile settings in the read-only screen. Click Save to save and go to the next screen. Figure 16   Profile: Confirm Save8Click Activate Now to use the new profile immediately. Otherwise, click the Activate Later button. If you clicked Activate Later, you can select the profile from the list in the Profile screen and click Connect to activate it.

PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). Table 13   Wizard Step 3: ISP ParametersCONNECTION TYPE DESCRIPTIONEthernet Select the Ethernet option when the WAN port is used as a regular Ethernet. PPPoE Select the PPP over Ethernet option for a dial-up connection. If your ISP gave you a an IP address and/or subnet mask, then select PPTP.PPTP Select the PPTP option for a dial-up connection.
Chapter 4 Connection WizardNBG318S User’s Guide62One of the benefits of PPPoE is the ability to let end users 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 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 NBG318S (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG318S 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 35   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 14   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 WizardNBG318S 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 NBG318S, 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 NBG318S 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 NBG318S 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 NBG318S 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.
Chapter 4 Connection WizardNBG318S User’s Guide662If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses.4.4.8  WAN IP and DNS Server Address AssignmentThe following wizard screen allows you to assign a fixed WAN IP address and DNS server addresses.

NBG318S User’s Guide 73CHAPTER  5 Wireless LANThis chapter discusses how to configure the wireless network settings in your NBG318S. 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 43   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 NBG318S 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.
Chapter 5 Wireless LANNBG318S 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.RequirementsTo add a wireless LAN to your existing network, make sure you have the following:1an access point (AP) or a router with the wireless feature 2at least one wireless network card/adapter which varies according to your computer. • If you have a desktop, use either a wireless USB adapter or a wireless PCI adapter.• If you have a laptop, use either a wireless USB adapter or a wireless CardBus card.3a RADIUS server only if you want to use IEEE802.1x, WPA or WPA2To have two or more computers communicate with each other wirelessly without an AP or wireless router, make sure you have the following:1two or more wireless network cards/adapters which vary according to your computers. • If you have a desktop, use either a wireless USB adapter or a wireless PCI adapter.• If you have a laptop, use either a wireless USB adapter or a wireless CardBus card.Setup InformationTo set up your wireless network using an AP or wireless router, make sure your AP or wireless router and wireless network card(s)/adapter(s) use the same following settings:• SSID:_____________________• Channel: auto or _________• Network type of a wireless network card/adapter: Infrastructure• wireless standard: IEEE 802.11b, g, b/g or a• Security: (  ) None(  ) WEP (64bit, 128bit or 256bit key) (ASCII or Hex):________________(  ) IEEE 802.1x(  ) WPA-PSK (TKIP or AES):_______________(  ) WPA (TKIP or AES)(  ) WPA2-PSK (TKIP or AES):______________
 Chapter 5 Wireless LANNBG318S User’s Guide 75(  ) WPA2 (TKIP or AES)• Preamble type (if available): auto, short or longTo set up your wireless network without an AP or wireless router, make sure wireless network cards/adapters use the same following settings:• Network type: Ad-Hoc• SSID:_____________________• Channel: _________________• wireless standard: IEEE 802.11b, g, b/g or a• Security: (  ) None(  ) WEP (64bit, 128bit or 256bit key) (ASCII or Hex):________________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.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.
Chapter 5 Wireless LANNBG318S User’s Guide765.2.3  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.If 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 76 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.Table 22   Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No Security WPAStatic WEPWPA-PSKStrongest WPA2-PSK WPA2
 Chapter 5 Wireless LANNBG318S User’s Guide 77"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.When you select WPA2 or WPA2-PSK in your NBG318S, 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 NBG318S.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  RoamingA wireless station is a device with an IEEE 802.11a/b/g compliant wireless interface. An access point (AP) acts as a bridge between the wireless and wired networks. An AP creates its own wireless coverage area. A wireless station can associate with a particular access point only if it is within the access point’s coverage area.In a network environment with multiple access points, wireless stations are able to switch from one access point to another as they move between the coverage areas. This is known as roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate access point depending on the signal strength, network utilization or other factors.The roaming feature on the access points allows the access points to relay information about the wireless stations to each other. When a wireless station moves from a coverage area to another, it scans and uses the channel of a new access point, which then informs the other access points on the LAN about the change. An example is shown in Figure 44 on page 78.With roaming, a wireless LAN mobile user enjoys a continuous connection to the wired network through an access point while moving around the wireless LAN.Enable roaming to exchange the latest bridge information of all wireless stations between APs when a wireless station moves between coverage areas. Wireless stations can still associate with other APs even if you disable roaming. Enabling roaming ensures correct traffic forwarding (bridge tables are updated) and maximum AP efficiency. The AP deletes records of wireless stations that associate with other APs (Non-ZyXEL APs may not be able to perform this). 802.1x authentication information is not exchanged (at the time of writing).
Chapter 5 Wireless LANNBG318S User’s Guide78Figure 44   Roaming ExampleThe steps below describe the roaming process.1Wireless station Y moves from the coverage area of access point AP 1 to that of access point AP 2. 2Wireless station Y scans and detects the signal of access point AP 2. 3Wireless station Y sends an association request to access point AP 2.4Access point AP 2 acknowledges the presence of wireless station Y and relays this information to access point AP 1 through the wired LAN. 5Access point AP 1 updates the new position of wireless station Y.5.3.1  Requirements for RoamingThe following requirements must be met in order for wireless stations to roam between the coverage areas. 1All the access points must be on the same subnet and configured with the same ESSID. 2If IEEE 802.1x user authentication is enabled and to be done locally on the access point, the new access point must have the user profile for the wireless station.3The adjacent access points should use different radio channels when their coverage areas overlap. 4All access points must use the same port number to relay roaming information. 5The access points must be connected to the Ethernet and be able to get IP addresses from a DHCP server if using dynamic IP address assignment. 5.4  Quality of ServiceThis section discusses the Quality of Service (QoS) features available on the NBG318S.
 Chapter 5 Wireless LANNBG318S User’s Guide 795.4.1  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 NBG318S uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag or DSCP information in each packet’s header. The NBG318S 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).5.4.1.1  WMM QoS PrioritiesThe following table describes the WMM QoS priority levels that the NBG318S uses.5.5  General Wireless LAN Screen "If you are configuring the NBG318S from a computer connected to the wireless LAN and you change the NBG318S’s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NBG318S’s new settings.Click Network > Wireless LAN to open the General screen.Table 23   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.
