The following table shows the duration of the button press and the corresponding action. 3.
Chapter 4: Username: Sets the username registered for the DDNS service. Services Tab The Services top-level tab contains the configuration pages for Dynamic DNS and Discovery. 4.1 Dynamic DNS The domain name system (DNS) translates a URL like www.yahoo.com to an IP address like 206.190.36.45. Dynamic DNS (DDNS) allows the with the public IP address to be reached from the internet via a URL even if its IP address is dynamically changing. Password: Sets the password registered for the DDNS service.
Chapter 5: Network Tab The Network → Interfaces tab shows an overview of the network interfaces. You can view and configure the interfaces of the local area network (LAN) zone as well as the wide area network (WAN) zone. Network address translation (NAT) occurs between these two network zones. The radio that performs the NAT is called a gateway. A gateway is a network point that acts as an entrance to another network. Figure 36: An infotip appears when hovering the mouse over an icon.
or Static address, where you can specify the device IP address. Other protocols are PPTP, PPPoE, and L2TP. VPN Server: Specifies the IP address of the remote PPTP server for the virtual private network (VPN). Protocol – Static address PAP/CHAP username: Sets the username for the Password Authentication Protocol (PAP) or the Challenge-Handshake Authentication Protocol (CHAP). IPv4 address: Sets the IP address of the device as seen from the WAN zone. IPv4 netmask: Sets the subnet mask e.g. 255.255.255.0.
L2TP Server: Specifies the IP address of the remote L2TP server. Configure L2TP IP settings: Upon clicking the “Configure...” button, the L2TP Common Configuration page would be displayed. The protocol DHCP client or Static address can be selected. The corresponding options are explained within this section (5.1.1 Common Configuration). Advanced Settings The following are options in the Advanced Settings section tab. Some of these options are shown, depending on the protocol being used.
Protocol – DHCP client The Dynamic Host Configuration Protocol (DHCP) is a standardized networking protocol used by servers on an IP network to allocate IP addresses automatically to client devices. Hostname to send when requesting DHCP: Specifies the name of this device as seen by the remote DHCP server. Figure 38: Status of the “br-lan” interface of the LAN zone.
Physical Settings DHCP-Options: Defines additional DHCP options, for example "6,192.168.2.1,192.168.2.2" which advertises different DNS servers to clients. Normally, connected devices would take this board's IP address as the default gateway. To set an alternative default gateway, add the DHCP option "3,192.168.2.3" for example. More information can be found in this link: http://wiki.openwrt.org/doc/uci/dhcp. Enable STP: Enables the Spanning Tree Protocol on this bridge. It is unchecked by default. 5.2.
Figure 42: The Associated Stations are also shown on the Wireless Overview page. The MAC address, network name, received signal strength, noise power, transmit rate, receive rate, and transmission quality for each station are displayed. 5.3.2 Spectrum: Interference Analyzer for AP Figure 41: The Wireless Overview page showing two radios. In Figure 43, two tabs are shown at the top, wifi0: Master “A600-2” and wifi1: Client “Altum_AC600”. These correspond to the two radios in the window below.

country where the device is operating in. The transmit power levels for each channel are tuned accordingly. may also be manually selected. An AP and its station must have the same channel in order to communicate. The country codes should match for all radios on the network. Obey Regulatory Power: Obeys the power regulations specified by each country.
Advanced Settings is 200 ms, a beacon will be transmitted from the radio portion every 50 ms, from each VAP in a round-robin fashion. The default value of the interval is 100 ms. Adaptive noise immunity: Controls radio sensitivity in the face of noise sources. Adaptive noise immunity allows the AP to reject spurs and non-WLAN noise. An advantage is that the AP would have to spend less time decoding the signal, resulting in lower packet loss rate.
Note: Setting more than 1 station on a board is not supported because there can only be one default gateway. Both 2.4 and 5 GHz radios cannot be in Station mode at the same time. ESSID: Specifies the name or extended service set identifier (ESSID) of the wireless network as it is provided in the beacon message. The network name can be up to 32 characters in length and can contain spaces. When running in AP mode, it is the name of the network as advertised in the beacon message.
Multiple stations or Stations WDS can connect to an AP WDS (unless the PTP Country code is used and the PTP-MAC of the peer radio is entered) In Figure 52, the Add button creates a virtual access point (VAP) on the second . You should choose AP WDS mode for the VAP's wireless network e.g. “M8” so that devices in Station WDS mode can connect to this network. The pair of Station WDS and AP WDS on the same board extends the wireless coverage.
method. IEEE 802.1X is equivalent to EAP over LAN or WLAN. Enterprise networks commonly use this authentication method. WPA or WPA2 with EAP (AP Mode) NAS ID: Specifies the identity of the network access server (NAS). WPA or WPA2 with EAP (Station Mode) Figure 52: Encryption options for WPA-EAP or WPA2-EAP in Station mode. Figure 51: Encryption options for WPA-EAP or WPA2-EAP in AP mode. Cipher: Can be set to Auto, CCMP (AES), or TKIP and CCMP (AES).

Identity: Sets the identity used by the supplicant for EAP authentication. Password: Sets the password used by the supplicant for EAP authentication. to consider when setting this parameter.
5.5 VLANs Netmask: States the netmask of the subnet defined by this VLAN. A local area network (LAN) can be divided into multiple distinct virtual LANs (VLANs) with the use of VLAN switches. This improves the management and security of the network. The broadcast domain of a device on a VLAN is confined to all devices on the same VLAN. Bridge WIFI: Selects the wireless network for which its interface would be bridged to the “eth0.VID” port.
Zone Settings Figure 57: Custom hostname entries. Figure 59: General Settings for the Firewall Zones. Note: The computers in the same subnet need to set the IP address of this device as their preferred DNS server in order to interpret these custom hostnames. Enable SYN-flood protection: Checked by default. 5.7 Static Routes Input: To accept by default. The Network → Static Routes page shows the static IPv4 routes. Output: To accept by default. Drop invalid packets: Unchecked by default.
5.8.3 Traffic Rules The Network → Firewall → Traffic Rules page configures the traffic rules and source NAT. Traffic Rules Traffic rules define policies for packets travelling between different zones, for example to reject traffic between certain hosts or to open WAN ports on the . Figure 63: You can choose to open ports on the or add new forwarding rules.

With QoS, you can shape network traffic selected by addresses, ports, or services. You can limit the download and upload speeds. Network QoS is disabled by default. Figure 69: Network QoS settings.
• Chapter 6: Final Notes ping 192.168.3.77 (if your computer's IP address is 192.168.3.77 for example.) They should be able to give the ping responses. Logout: Logs out of the radio's web page. An IP address conflict would cause unstable pings. Switch to another address and ping the conflicting address to check. If using a Windows computer, you should run the command arp -d * if the network configuration has changed.
6.1.4 Mobile phone connects but cannot access Internet Solution: Turn off the radio for 10 seconds and then turn it on again. A mobile phone or any connected Wifi user would not be able to access the Internet if the default gateway is not set correctly on the radio. 6.2 Resetting to factory default The option for the default gateway is found in Network → Interfaces → LAN → Common Configuration → General Setup → IPv4 gateway.
