The following screen displays: WPS Wizard The WPS Wizard helps you add a WPS-capable client device (a wireless device or computer) to your network. On the client device, you need to either press its WPS button or locate its WPS PIN. 1. Select Advanced > WPS Wizard. 2. Click Next. The following screen lets you select the method for adding the WPS client (a wireless device or computer). You can use either the push button or PIN method. 3. Select either Push Button or PIN Number. • To use the push button method, either click the WPS button on this screen, or press the WPS button on the side of the router until the LED status changes. Within 2 minutes, go to the wireless client and press its WPS button to join the network without entering a password. • To use the PIN method, select the PIN Number radio button, enter the client security PIN, and click Next. Within 2 minutes, go to the client device and use its WPS software to join the network without entering a password. The router attempts to add the WPS-capable device. The WPS LED on the router blinks green. When the router establishes a WPS connection, the LED is solid green, and the router WPS screen displays a confirmation message. 4. Repeat Step 2 and Step 3 to add another WPS client to your network. Setup Menu Select Advanced > Setup to display the Setup menu. The following selections are available: • Internet Setup. This is a shortcut to the same Internet Setup screen that you can access from the dashboard on the Basic Home screen. See Internet Setup on page 23. • Wireless Setup. This is a shortcut to the same Wireless Setup screen that you can access from the dashboard on the Basic Home screen. See Basic Wireless Settings on page 29. • WAN Setup. Internet (WAN) setup. See WAN Setup on page 39. • LAN Setup. Local area network (LAN) setup. See LAN Setup on page 42. • QoS Setup. Quality of Service (QoS) setup. See Quality of Service (QoS) Setup on page 45. • Guest Network. This is a shortcut to the same Guest Network screen that you can access from the dashboard on the Basic Home screen. See Guest Networks on page 32. WAN Setup The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and enable the router to respond to a ping on the WAN (Internet) port. Select Advanced > Setup > WAN Setup to view the following screen: • Disable Port Scan and DoS Protection. DoS protection protects your LAN against denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, Teardrop Attack, UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This should be disabled only in special circumstances. • Default DMZ Server. This feature is sometimes helpful when you are playing online games or videoconferencing. Be careful when using this feature because it makes the firewall security less effective. See the following section, Default DMZ Server, for more details. • Respond to Ping on Internet Port. If you want the router to respond to a ping from the Internet, select this check box. Use this only as a diagnostic tool because it allows your router to be discovered. Do not select this check box unless you have a specific reason. • Disable IGMP Proxying. IGMP proxying allows a computer on the local area network (LAN) to receive the multicast traffic it is interested in from the Internet. If you do not need this feature, you can select this check box to disable it. • MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might need to reduce the MTU. This is rarely required, and should not be done unless you are sure that it is necessary for your ISP connection. See Change the MTU Size on page 40. • NAT Filtering. Network Address Translation (NAT) determines how the router processes inbound traffic. Secured NAT provides a secured firewall to protect the computers on the LAN from attacks from the Internet, but might prevent some Internet games, point-to-point applications, or multimedia applications from functioning. Open NAT provides a much less secured firewall, but allows almost all Internet applications to function. Default DMZ Server eTThe default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The router is programmed to recognize some of these applications and to work correctly with them, but other applications might not function well. In some cases, one local computer can run the application correctly if that computer’s IP address is entered as the default DMZ server. DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network. Incoming traffic from the Internet i...
