In PPPoE/PPPoA mode, please select “PPPoE LLC”, “PPPoE VC-Mux”, “PPPoA LLC”, or “PPPoA VC-Mux”. Connection Always On – The connection will be kept always on. If the connection is interrupted, the router will re-connect automatically. Connect On-Demand – Only connect when you want to surf the Internet. “Close if idle for xx minutes” is set to stop the connection when the network traffic is not sending or receiving after an idle time. TCP MSS Option The TCP MSS Option enables the configuration of the maximum
AirLive WT-2000ARM User’s Manual 27 segment size (MSS) for transient packets that traverse a router, specifically TCP segments in the SYN bit set, when PPPoE is being used in the network. Please specify the MSS range from 100 to 1452 bytes or 0 byte as the default value. Parameter Description Get IP Address Choose Static or Dynamic IP Address. If Static IP is selected, please set the IP Address, Subnet Mask and Gateway obtained from your ISP. Static IP Address Enter the IP Address assigned by your ISP. IP Subnet Mask Enter the Subnet Mask assigned by your ISP. Gateway Enter the Gateway assigned by your ISP. NAT NAT (Network Address Translation), an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. When NAT is enabled, the router will help to make all necessary IP address translations for the PC connected to the router to access the Internet. Default Route When “Default Router” is enabled, all the packets for destinations not known by the routers routing table are sent to the default route. By default, it is enabled. TCP MTU Option MTU (Maximum Transmission Unit) determine the maximum size of each packet in any transmission within the network. Please specify the MTU range from 100 to 1500 bytes or 0 byte as the default value. Dynamic Route Dynamic routing allows routing tables in routers to change as the possible routes change. This router supports RIP1, RIP2-B and RIP2-M protocols for dynamic routing. After the RIP protocol is selected, please choose the RIP direction from “None”, “Both”, “IN Only” or “OUT Only”. Parameter Description

After the RIP protocol is selected, please choose the RIP direction from “None”, “Both”, “IN
AirLive WT-2000ARM User’s Manual 29 Only” or “OUT Only”. Multicast Specify the method of transmitting data simultaneously to many receivers. Please select “IGMP v1” or “IGMP v2” as the multicast protocol or select “Disabled” to disable the function. z DHCP Parameter Description DHCP You can enable or disable the DHCP server. By enabling the DHCP server the router will automatically give your LAN clients an IP address. If the DHCP is not enabled then you’ll have to manually set your LAN client’s IP addresses. Starting IP Address If the DHCP Server is enabled, please set the “Starting IP Address” which will be the first IP Address assigned to the LAN client. By default, the “Starting IP Address” is 192.168.2.100. IP Pool Count You can select a particular IP address range for your DHCP server to issue IP addresses to your LAN Clients. By default, the “IP Pool Count” is 100. The IP range is starting from IP 192.168.2.100 to 192.168.2.199. Parameter Description Lease Time In the Lease Time setting you can specify the time period that the DHCP Server lends an IP address to your LAN clients. The DHCP will change your LAN client’s IP address when this time threshold period is terminated. DNS Relay A Domain Name System (DNS) server is like an index of IP addresses and Web addresses. If you type a Web address into your browser, such as “www.router.com”, a DNS server will find that name in its index and the matching IP address. Please select “Use Auto Discovered DNS Server Only” to auto set the DNS Server. If there is a DNS server that you would rather to use, please select “Use Discovered DNS Server Only” and you need to specify the IP address of that DNS server. Primary DNS Server Enter the ISP’s DNS Server IP Address; or you can specify your own
AirLive WT-2000ARM User’s Manual 30 preferred DNS Server IP Address. Secondary DNS Server This is optional. You can enter another DNS Server’s IP Address as a backup. The secondary DNS will be used should the Primary DNS fail. Wireless z Wireless LAN Parameter Description Access Point Activated or deactivated the wireless function of the router. When it is activated, the router will be an access point for other wireless clients to connect wirelessly. SSID The SSID (up to 32 printable ASCII characters) is the unique name identified in a WLAN. The ID prevents the unintentional merging of two co-located WLANs. The default SSID of the router is “airlive”. Parameter Description
AirLive WT-2000ARM User’s Manual 31 Broadcast SSID Select “Yes” to make the SSID to be visible so wireless clients can scan the router within the network. Select “No” if you want to hide the SSID of the router. Wireless clients have to set the same SSID of the router in order to access the network. Channel ID The radio channel used by the wireless LAN. All devices in the same wireless LAN should use the same channel. Authentication Type To prevent unauthorized wireless clients from accessing the router, this router supports WEP, WPA-PSK and WPA2-PSK authentication type. If the router has enabled the authentication, all the wireless clients’ settings have to be consistent with the router for building the connection. z WEP/WPA-PSK/WPA2-PSK Parameter Description WEP-64Bits WEP is less level of security than WPA. WEP supports 64-bit and 128-bit key lengths to encrypt the wireless data. The longer key length will provide higher security. When “WEP-64Bits” is selected, you have to enter exactly 5 ASCII characters (“a-z” and “0-9”) or 10 hexadecimal digits (0-9, a-f) for each Key (1-4). WEP-128Bits When “WEP-128Bits” is selected, you have to enter exactly 13 ASCII characters (“a-z” and “0-9”) or 26 hexadecimal digits (0-9, a-f) for each Key (1-4). Parameter Description WPA-PSK WPA-PSK is suitable for home and small business. It uses TKIP for data encryption. When “WPA-PSK” is selected, please enter 8-64 characters as the “Pre-Shared Key”. WPA2-PSK WPA2-PSK is also for home and small business. The difference between WPA-PSK and WPA2-PSK is that WPA2-PSK provides data encryption via the AES. In contrast, WPA-PSK uses Temporal Key Integrity Protocol (TKIP). WPA2-PSK offers the highest level of security available. When “WPA2-PSK” is selected, please enter 8-64 characters as the “Pre-Shared Key”.
AirLive WT-2000ARM User’s Manual 32 z Advanced Setting Parameter Description Beacon Interval The interval of time that this wireless router broadcast a beacon. Beacon is used to synchronize the wireless network. The range for the beacon period is between 20 and 1000 with a typical value of 100 (milliseconds). RTS/CTS Threshold When the packet size is smaller than the RTS threshold, the wireless router will not use the RTS/CTS mechanism to send this packet. The range is from 1500 to 2347. Fragmentation Threshold Fragment Threshold specifies the maximum size of packet during the fragmentation of data to be transmitted. If you set this value too low, it will result in bad performance. Enter a value from 256 to 2346. DTIM Determines the interval the Access Point will send its broadcast traffic. The range is from 1 to 255 and the default value is 3 beacons. Parameter Description 802.11b/g 802.11 b – This router will only work in 802.11b mode.
