38 5) Close Scan and click OK to save your settings.
39 6) Go to Wireless Security page and set the wireless security settings exactly as they are on the link partner (Router 1). 7) Go to DHCP Server to disable the DHCP on Router 2. Now you have finished all settings on Router 2 required for WDS.
40 2. Configure Router 1: 1) Go to wireless section on Router 1 and specify WDS (or WDS Bridge) as its wireless working mode. 2) Manually enter Router 2's MAC address (Also, you can use the Scan option as mentioned above) and click OK to finish your settings. 3. Configure PC3 and PC4：
41 1) Set PC3 and PC4 to Obtain an IP address automatically. 2) When the two PCs get IP addresses,
42 try below steps to verify the WDS connection: Click Start-> Run on PC3, input cmd on the appearing window and then click OK. Input ping 192.168.0.1 and press Enter. If you get a screen as seen below, you have successfully implemented WDS.
43 Note: 1. WDS feature can only be implemented between 2 WDS-capable wireless devices. Plus, SSID, channel, security settings and security key must be exactly the same on both such devices. 2. To ensure a proper wireless connection, do not change any settings on the two devices after WDS is successfully implemented. 4.2 Wireless Security This section allows you to secure your wireless network and block unauthorized accesses and malicious packet sniffing. To encrypt your wireless network, do as follows: 1. Select the wireless network (SSID) you wish to encrypt. 2. Disable WPS. (WPS is enabled on the router by default. If you want to use other security modes, you must first disable the WPS.) 3. Select a proper security mode and cipher type (also known as WPA Algorithm or WPA Encryption Type). WPA-PSK and AES are recommended by system default. (5 security modes are available for your selection. Among them, WPA-PSK outstands with greater compatibility and security. For more information of other security modes, see appendix 2) Specify a security key that includes at least 8 characters. 4. Click OK to complete your settings.
44 WPS Wi-Fi Protected Setup makes it easy for home users who know little of wireless security to establish a home network, as well as to add new devices to an existing network without entering long passphrases or configuring complicated settings. Simply enter a PIN code or press the software PBC button or hardware WPS button (if any) and a secure wireless connection is established. Operation Instructions: PBC: To use WPS-PBC, try two ways below: 1) Press the hardware WPS button on the router for about 1 second and then enable WPS/PBC on the client device within 2 minutes; 2) Press the hardware WPS button on the router for about 1 second and then enable WPS/PBC on the client device within 2 minutes; PIN: On the wireless security page, enable WPS, select PIN and enter the
45 8-digit PIN code from network adapter; then, within 2 minutes, enable WPS/PIN on the client device; Note: 1. With WPS successfully enabled, the WPS LED on the router keeps blinking for about 2 minutes, and during this time, you can enable WPS on a wireless adapter; if the adapter successfully joins the wireless network, the WPS LED will display a solid light. Repeat steps above if you want to add more wireless adapters to the router. 2. Reset OOB: Clicking this button will reset SSID to factory default and disable security mode. 3. Existing wireless settings will still be maintained by default after a successful WPS connection. Namely security settings and SSID on the router will still be the same. If you want to generate a random wireless key via WPS, click Reset OOB and then follow WPS setup instructions above.
46 Note: 1. To use the WPS security, the wireless client must be also WPS-capable. 2. Before you press the hardware WPS button on the device for WPS/PBC connection, making sure the WPS feature has been enabled on the device. 4.3 Wireless Access Control The Access Control feature allows you to specify a list of devices to Permit or Forbid a connection to your wireless network via the devices’ MAC addresses. All other devices not listed as Permitted will be Forbidden and vice versa. 1. Select the wireless network (SSID) you wish to enable Access Control on. 2. MAC Address Filter: Select Permit or Forbid from the drop-down list. 3. To permit a wireless device to connect to your wireless network, select Permit (or Allow), enter its MAC address, click Add and then OK. Then
47 only this device listed as “Permitted” will be able to connect to your wireless network; all other wireless devices will forbidden. Step1. Select the wireless network (SSID) you wish to enable Access Control on. Step2. Select Permit from the corresponding drop-down menu. Step3. Enter the MAC address you wish to permit in the MAC address box and click Add. Step4. Click OK to save your settings. You can add more wireless MAC addresses you wish to allow. Example: To forbid the PC at the MAC address of C8:3A:35:65:82:E6 from connecting to your wireless network, do as follows: Step1. Select an SSID, say, Wilink_home. Step2. Select Forbid (or Deny) from the corresponding drop-down menu. Step3. Enter C8:3A:35:65:82:E6 in the MAC address box and click Add. Step4. Click OK to save your settings. You can add more wireless MAC addresses you wish to forbid. 4.4 Wireless Client Here you can see a list of wireless devices connected to the router, including their MAC addresses and bandwidth
48 Note: The bandwidth here refers to the channel bandwidth instead of wireless connection rate.
49 Chapter 5 Bandwidth Control 5.1 Bandwidth Control Use this section to manage bandwidth allocation to devices on your LAN. If there are multiple PCs behind your router competing for limited bandwidth resource, then you can use this feature to specify a reasonable amount of bandwidth for each such PC, so that no one will be over stuffed or starved to death. 1. Enable Bandwidth Control: Check or uncheck the box to 2. Enable or disable the bandwidth control feature. 3. IP Address: Specify the same IP address (say, 100, 100) or two different IP addresses (say, 100, 110) in both boxes to specify a single IP address or an IP range to which the current bandwidth control rule will apply. 4. Upload/Download: Select to control bandwidth over data upload or download. 5. Bandwidth Range: Specify an upload/download bandwidth range limit on specified PC(s). The unit is KByte/s. 1M=128KByte/s. Note that maximum upload/download bandwidth should not exceed your router's WAN bandwidth limit. (Consult your ISP if you are not clear.).
50 6. Enable: Check to enable current rule. (When disabled, corresponding entry will not take effect though existing in fact.) 7. Add to List: Click to add current rule to the rule list. 8. OK: Click to activate your settings. For example: If you are sharing a 4M broadband connection with a neighbor, who always exhausts the bandwidth resource downloading data, this feature will help. Simply specify half of the 4M bandwidth for your neighbor's PC (say, 192.168.0.100) and you will no longer need to struggle for bandwidth and your neighbor will only get up to 2M bandwidth. To do so, follow instructions below: 11.. CChheecckk EEnnaabbllee.. 22. Input "192.168.0.100" in both IP address boxes. 33.. Select Download. 44.. Enter "256" in both bandwidth range fields. 55.. Check Enable. 66.. Click Add To List 77.. Click OK. 5.2 Traffic Statistics Traffic Statistics allows you to see at a glance how much traffic each device in your network is using.

Received Message: Displays the number of packets received by a corresponding PC via the device since Statistics is enabled. Received Bytes: Displays the number of Bytes received by a corresponding PC via the device since Statistics is enabled. The unit is MByte.
52 Chapter 6 Special Applications 6.1 Port Range Forwarding Port range forwarding is useful for web servers, ftp servers, e-mail servers, gaming and other specialized Internet applications. When you enable port forwarding, the communication requests from the Internet to your router’s WAN port will be forwarded to the specified LAN IP address. As seen in the figure above, to let PC3 access service ports on PC1, you must first configure port forwarding settings on the router to which PC1 is uplinked.
53 1. Start/End Port: Specify a range of ports between 1~65535 (for a single port, enter the port number in both Start and End fields, say, 21 for FTP). Contact corresponding service provider if you don't know the port number of the service to use. 2. LAN IP: Specify the internal host’s IP address. Be sure to statically assign the host’s IP address to make this function constant. 3. Protocol: Specify the protocol required for the service utilizing the port(s). 4. Enable: Check to enable current settings. 5. OK: Click to activate your settings. Now, your friends only need to enter ftp://xxx.xxx.xxx.xxx:21 in their browsers to access your FTP server xxx.xxx.xxx.xxx is the router's WAN IP address. Assuming it is 172.16.102.89, and then your friends need to enter ftp://172.16.102.89：21 in their browsers. For example: You want to share some large files with your friends who are not in your LAN; however it is not convenient to transfer such large files across network. Then, you can set up your own PC as a FTP server and use the Port (Range) Forwarding feature to let your friends access these files. Assuming that the static IP address of the FTP server (Namely, your PC) is 192.168.0.10, you want your friends to access this FTP server through default port of 21 using the TCP protocol, then do as follows: 1. Start/End Port: Enter 21 in both Start Port and End Port fields. 2. LAN IP: Enter 192.168.0.10 3. Protocol: Select TCP. 4. Enable: Check to enable current settings. 5. OK: Click to activate your settings. Note: If you include port 80 on this section, you must set the port for remote (web-based) management to a different number than 80, such as 8080, otherwise the virtual server feature may not take effect. 6.2 DMZ Host The DMZ (De-Militarized Zone) function disables the firewall on the router for one device for a special purpose service such as Internet gaming or video conferencing. Enabling DMZ host may expose your local network to potential attacks. So it is advisable to use it with caution.
54 1. DMZ Host IP Address: The IP Address of the device for which the router’s firewall will be disabled. Be sure to statically set the IP Address of that device for this function to be consistent. 2. Enable: Check/uncheck to enable/disable the DMZ host feature. 3. OK: Click to enable your settings. Note: Once enabled, the DMZ host loses protection from device's firewall and becomes vulnerable to attacks. 6.3 DDNS Dynamic DNS or DDNS is a term used for the updating in real time of Internet Domain Name System (DNS) name servers. Dynamic DNS or DDNS is a term used for the updating in real time of Internet Domain Name System (DNS) name servers. We use a numeric IP address allocated by Internet Service Provider (ISP) to connect to Internet; the address may either be stable ("static"), or may change from one session on the Internet to the next ("dynamic"). However, a numeric address is inconvenient to remember; an address which changes unpredictably makes connection impossible. The DDNS provider allocates a static host name to the user; whenever the user is allocated a new IP address this is communicated to the DDNS provider by software running on a computer or network device at that address; the provider distributes the association between the host name and the address to the Internet's DNS servers so that they may resolve DNS queries. Thus, uninterrupted access to devices and services whose numeric IP address may change is maintained. (You need to have an account with one of the Service Providers in the drop-down menu first.)
55 1. DDNS Service: Select to enable/disable the DDNS feature. 2. Service Provider: Select your DDNS service provider from the drop-down menu. (Here you can see a list of available service providers. Note that service providers not listed here are not available for use.) 3. User Name: Enter the registered user name. 4. Password: Enter the registered password. 5. Domain Name: Enter the domain name you register, say, Wilink.dyndns.org. 6. OK: Click to activate your settings. Note: This feature is usually used together with virtual server. Configure necessary settings on port forwarding interface and enter the information provided by your DDNS service provider on the DDNS screen. Others can access your web server by simply entering http://wilink.dyndns.org in their browser address bar. 6.4 UPNP The Universal Plug and Play (UPnP) feature allows network devices, such as computers from Internet, to access resources on local host or devices as needed. UPnP-enabled devices can be discovered automatically by the UPnP service application on the LAN. This feature is enabled by default. No settings are required. Enable UPnP: Check/uncheck to enable/disable the UPnP feature.
56 OK: Click to complete your settings. 6.5 Static Routing When there are several routers in the network, you may want to set up static routing. Static routing determines the path of the data in your network. You can use this feature to allow users on different IP domains to access the Internet via this device. It is not recommended to use this setting unless you are familiar with static routing. In most cases, dynamic routing is recommended, because this feature allows the router to detect the physical changes of the network layout automatically. If you want to use static routing, make sure the router’s DHCP function is disabled. 1. Destination Network IP Address: Specify a single IP address, say, 172.17.0.100, or an IP net segment, .say, 192.168.88.0. 2. Subnet Mask: Specify a Subnet Mask that corresponds to the specified destination IP. 3. Gateway: Specify the IP address for next hop. 4. OK: Click to activate your settings. Note: 1. Gateway must be on the same IP net segment as device's LAN/WAN IP address. 2. Subnet Mask must be entered 255.255.255.255 if destination IP address is a host. 3. Subnet Mask must be entered accordingly if destination IP address represents an IP network segment. It must correspond to the specified IP address. For example, for IP address of 10.0.0.0, you may enter a
57 subnet mask of 255.0.0.0. 6.6 Routing Table This page displays the device core routing table which lists destination IP, subnet mask, gateway, hop count and interface. The principal task for a router is to look for an optimal transfer path for each data packet passing through it, and transfer it to the specified destination. To complete this work, the router stores and maintains related data of various transfer paths, i.e. establishing a routing table, for future route selection.

76 Appendix 2 Glossary Channel A communication channel, also known as channel, refers either to a physical transmission medium such as a wire or to a logical connection over a multiplexed medium such as a radio channel. It is used to transfer an information signal, such as a digital bit stream, from one or more transmitters to one or more receivers. If there is only one AP in the range, select any channel you like. The default is Auto. If there are several APs coexisting in the same area, it is advisable that you select a different channel for each AP to operate on, minimizing the interference between neighboring APs. For example, if 3 American- standard APs coexist in one area, you can set their channels respectively to 1, 6 and 11 to avoid mutual interference. SSID Service set identifier (SSID) is used to identify a particular 802.11 wireless LAN. It is the name of a specific wireless network. To let your wireless network adapter roam among different APs, you must set all APs’ SSID to the same name. WPA/WPA2 The WPA protocol implements the majority of the IEEE 802.11i standard. It enhances data encryption through the Temporal Key Integrity Protocol (TKIP) which is a 128-bit per-packet key, meaning that it dynamically generates a new key for each packet. WPA also includes a message integrity check feature to prevent data packets from being hampered with. Only authorized network users can access the wireless network. The later WPA2 protocol features compliance with the full IEEE 802.11i standard and uses Advanced Encryption Standard (AES) in addition to TKIP encryption protocol to guarantee better security than that provided by WEP or WPA. Currently, WPA is supported by Windows XP SP1. IEEE 802.1X Authentication IEEE 802.1X Authentication is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.IEEE 802.1X defines the encapsulation of EAP
77 over LAN or EAPOL. 802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server. The supplicant is a client device (such as a laptop) that wishes to attach to the LAN/WLAN - though the term 'supplicant' is also used interchangeably to refer to the software running on the client that provides credentials to the authenticator. The authenticator is a network device, such as an Ethernet switch or wireless access point; and the authentication server is typically a host running software supporting the RADIUS and EAP protocols. The authenticator acts like a security guard to a protected network. The supplicant (i.e. client device) is not allowed access through the authenticator to the protected side of the network until the supplicant’s identity has been validated and authorized. With 802.1X port-based authentication, the supplicant provides credentials, such as user name / password or digital certificate, to the authenticator, and the authenticator forwards the credentials to the authentication server for verification. If the authentication server determines the credentials are valid, the supplicant (client device) is allowed to access resources located on the protected side of the network. PPPOE The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside Ethernet frames. Integrated PPP protocol implements authentication, encryption, and compression functions that traditional Ethernet cannot provide and can also be used in the cable modem and digital subscriber line (DSL) and Ethernet that provide access service to the users. Essentially, it is a protocol that allows to establish a point-to-point tunnel between two Ethernet interfaces within an Ethernet broadcast domain. DNS The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service resolves queries for these names into IP addresses for the purpose of locating computer services and devices worldwide. An often-used analogy to explain the Domain Name System is that it serves
78 as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. WDS A wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. All base stations in a wireless distribution system must be configured to use the same radio channel, method of encryption (none, WEP, or WPA) and the same encryption keys. They may be configured to different service set identifiers. WDS also requires every base station to be configured to forward to others in the system. WDS may also be considered a repeater mode because it appears to bridge and accept wireless clients at the same time (unlike traditional bridging).WDS may be incompatible between different products (even occasionally from the same vendor) since it is not certified by the Wi-Fi Alliance. WDS may provide two modes of wireless AP-to-AP connectivity: Wireless bridging, in which WDS APs communicate only with each other and don't allow wireless clients or stations (STA) to access them. Wireless repeating, in which APs communicate with each other and with wireless STAs. DMZ In computer security, a DMZ (sometimes referred to as a perimeter networking) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external attacker only has access to equipment in the DMZ, rather than any other part of the network. Hosts in the DMZ have limited connectivity to specific hosts in the internal network, although communication with other hosts in the DMZ and to the external network is allowed. This allows hosts in the DMZ to provide services to both the internal and external network, while an intervening firewall controls the traffic between the DMZ servers and the internal network clients. Any services such as Web servers, Mail servers, FTP servers and VoIP servers, etc. that are being provided to users on the external network can be
79 placed in the DMZ.
80 Appendix 3 FAQs This section provides solutions to problems that may occur during installation and operation of the device. Read the following if you are running into problems.

We will be more than happy to help you out as soon as possible. 1. Q: I entered the device’s LAN IP address in the web browser but cannot access the utility. What should I do? 1) Check whether device is functioning correctly. The SYS LED should blink a few seconds after device is powered up. If it does not light up, then some internal faults may have occurred. 2) Verify physical connectivity by checking whether a corresponding port’s link LED lights up. If not, try a different cable. Note that an illuminated light does NOT ALWAYS indicate successful connectivity. 3) Run the "ping 192.168.0.1" command. If you get replies from 192.168.0.1, open your browser and verify that Proxy server is disabled. In case that ping fails, press and hold the "RESET" button on your device for 7 seconds to restore factory default settings, and then run "ping192.168.0.1" again. 4) Contact our technical support for help if the problem still exists after you tried all the above. 2. Q: What should I do if I forget the login password to my device? A: Reset your device by pressing the Reset button for over 7 seconds. Note: All settings will be deleted and restored to factory defaults once you pressed the Reset button. 3. Q: My computer shows an IP address conflict error after having connected to the device. What should I do? 1) Check if there are other DHCP servers present in your LAN. If there are other DHCP servers except your router, disable them immediately. 2) The default IP address of the device is 192.168.0.1; make sure this address is not used by another PC or device. In case that two computers or devices share the same IP addresses, change either to a different address. 4. Q: I cannot access Internet and send/receive emails; what should I do?
81 This problem mainly happens to users who use the PPPoE or Dynamic IP Internet connection type. You need to change the MTU size (1492 by default). In this case, go to “WAN Settings” to change the MTU value from default 1480 to 1450 or 1400, etc. 5. Q: How do I share resources on my computer with users on Internet through the device? To let Internet users access internal servers on your LAN such as e-mail server, Web, FTP, via the device, use the "Virtual Server" feature. To do so, follow steps below: Step 1: Create your internal server, make sure the LAN users can access these servers and you need to know related service ports, for example, port number for Web server is 80; FTP is 21; SMTP is 25 and POP3 is 110. Step 2: Enter Port Forwarding (also called Port Range Forwarding on some products) screen from device web UI. Step 3: Complete the Start Port (also called External/Ext Port on some products) and End Port (also known as Internal Port on some products) fields, say, 80-80. Step 4: Input the internal server’s IP address. For example, assuming that your Web server’s IP address is 192.168. 0.10, then simply input it. Step 5: Select a proper protocol type: TCP, UDP, or Both depending on which protocol(s) your internal host is using. Step 6: Click Enable and save your settings. For your reference, we collected a list of some well-known service ports as follows: Server Protocol Service Port Web Server TCP 80 FTP Server TCP 21 Telnet TCP 23 Net Meeting TCP 1503、1720 MSN Messenger TCP/UDP File Send:6891-6900(TCP) Voice:1863, 6901(TCP) Voice:1863, 5190(UDP) PPTP VPN TCP 1723 Iphone5.0 TCP 22555 SMTP TCP 25 POP3 TCP 110
