9Wireless LAN Networking This section provides background information on wireless LAN networking technology. Consult the Glossary for definitions of the terminology used in this section. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The TEW-815DAP provides various transmission (data) rate options for you to select. In most networking scenarios, the factory default Best (automatic) setting proves the most efficient. This setting allows your TEW-815DAP to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the TEW-815DAP automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the TEW-815DAP gradually increases the transmission (data) rate again until it reaches the highest available transmission rate. Types of Wireless Networks Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-structure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS). To connect to a wired network within a coverage area using access points, set the operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode. AD-HOC (IBSS) NETWORK Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station.
10
11 When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network. In an ESS environment, users are able to move from one access point to another without losing the
12 connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client devices automatically switches to the channel used in BSS (2). Roaming in an ESS network diagram
13 Introduction The TEW-815DAP 802.11ac (draft 2.0)3x3 Gigabit Wireless Access Point is an high-performance, wireless Access Point that supports high-speed wireless networking at home, at work or in public places. Unlike most Access Points, the TEW-815DAP provides data transfers at up to 867Mbps when using 11AC connection. This Access Point is also back compatible with 802.11n or 802.11g or 11b devices. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 11ac’s speed when you mix 11ac /11n and 11b/g devices, but you will not lose the ability to communicate when you incorporate the 11ac standard into your 11b/g/n network. You may choose to slowly change your network by gradually replacing the 11b/g/n devices with 11ac devices.

14 Hardware Overview LED Indications: (from bottom to top) ¾ PWR/WPS ¾ WAN ¾ LAN ¾ Wireless 2.4G ¾ Wireless 5G Rear panel: (from bottom to top) • DC-IN • POWER SWITCH( EU) • LAN Installation Considerations The TEW-815DAP 802.11ac(draft 2.0)3X3 Gigabit Wireless Access Point lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines: 1 Keep the number of walls and ceilings between the TEW-815DAP and other network devices to a minimum - each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. 2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception. 3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. 4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise.
15 Getting Started For a typical wireless setup at home, please do the following: 1. You will need broadband Internet access (a Cable or DSL-subscriber line into your home or office) 2. Consult with your Cable or DSL provider for proper installation of the modem. 3. Connect the Cable or DSL modem to the TEW-815DAP Access Point (WAN port). 4. Ethernet LAN ports of the TEW-815DAP are Auto MDI/MDIX and will work with both Straight-Through and Cross-Over cable. Start 1. Plug in the power adapter and verify the Power & Ethernet LEDs are light. 2. To configure the Access Point, open your browser, type 'http://192.168.10.1' into the address bar 3.

29 Setup LAN Setting: This page allows you to configure the LAN of the Access Point IP Address The IP address of the this device on the local area network. Assign any unused IP address in the range of IP addresses available for the LAN. Subnet Mask The subnet mask of the local area network. Subnet Mask The subnet mask of the local area network. Gateway The IP address of the Access Point on the local area network. For example, 192.168.10.1. IP Address: The LAN address that you want to reserve.
30 MAC Address To input the MAC address of your system, enter it in manually or connect to the Access Point's Web-Management interface from the system and click the Copy Your PC's MAC Address button. A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is already located inside the computer, you can connect to the Access Point from the computer and click the Copy Your PC's MAC Address button to enter the MAC address. IPv6 Setting:
31 LAN IPv6 Setting 6to4 6to4 is provided as a transition for migrating from IPv4 to IPv6. It allows IPv6 packets to be transmitted over an IPv4 network through the automatic tunneling technology, and routes traffic between 6to4 and IPv6 networks. Native IPv6 only Native IPv6 refers to the network where IPv6 is the only transport protocol running. 6to4 + Native IPv6 Support 6to4 and Native IPv6 simultaneously. DNS server User need to key in the IPv6 DNS server address which is provided by ISP. 6to4 subnet ID Specifies, in hexadecimal notation, a subnet ID other than 0
32 Wireless Multiple SSID: You could configure the minimum number of Wireless settings for communication, such as Network Name (SSID) and Security Mode. The Access Point can be set simply with only the minimum setting items. Wireless Network Name (SSID) When you are browsing for available wireless networks, this is the name that will appear in the list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured
33 network name. Add up to three additional SSIDs to create virtual wireless networks from one wireless Access Point Access Point device. Add Additional Wireless Network Name (SSID) To add additional wireless Network Names simply add the name to the Multiple SSID field and click on apply at the bottom of the page. When finished, go to the Security section in this Users Guide for wireless security configuration. Security Mode Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network can be easily intercepted and interpreted by unauthorized users. WPA- Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the Access Point should employ. WPA Mode: WPA is the older standard; select this option if the clients that will be used with the Access Point only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With the "WPA2" option, the Access Point tries WPA2 first, but falls back to WPA if the client only supports WPA. With the "WPA2 Only" option, the Access Point associates only with clients that also support WPA2 security. Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES (Advanced Encryption Standard) is a very secure block based encryption. With the "TKIP and AES" option, the Access Point negotiates the cipher type with the client, and uses AES when available. Group Key Update Interval: The amount of time before the group key used for broadcast and multicast data is changed. WPA-PSK This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK). Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII (American Standard Code for Information Interchange) format at both ends of the wireless connection. It cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client.
34 WDS: This page allows you to configure Wireless Distribution System (WDS) for the wireless LAN interfaces. Wireless Distribution System (WDS) When WDS is enabled, this access point functions as a wireless repeater and is able to wirelessly communicate with other APs via WDS links. A WDS link is bidirectional; so this AP must know the MAC Address (creates the WDS link) of the other AP, and the other AP must have a WDS link back to this AP. Make sure the APs are configured with same channel.
35 (Note that WDS security is incompatible with mixed mode, like WPAPSK+WPA2PSK mixed, WEP AUTO and 802.1x, both feature cannot be used at the same time). Configuring WDS with TEW-815DAP Enable the option for WDS and input the MAC Address of the wireless device that also supports WDS in to the blank fields. You can add up to four additional devices in the spaces provided. Click on apply at the bottom of the page, to apply your setting changes. Enable the security seeing in security page, each WDS APs need to use same security setting. (Note: WDS supports wireless g/n modes. The use multiple Access Point will reduces the overall network throughput to ½ the TEW-815DAP.
36 Advanced: Use the Advanced Setup page to make detailed settings for the Wireless. Advanced Setup includes items that are not available from the Basic Setup page, such as Beacon Interval, etc Beacon Interval Beacons are packets sent by a wireless Access Point to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds. DTIM A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the wireless Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255.
37 Fragmentation Threshold Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor performance. RTS Threshold When an excessive number of wireless packet collisions are occurring, wireless performance can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the RTS Threshold. This setting should remain at its default value of 2346 bytes. Short Preamble and Slot Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation.
38 WPS: Enable Enable the WPS feature. PIN Settings A PIN is a unique number that can be used to add the Access Point to an existing network or to create a new network. The default PIN may be printed on the bottom of the Access Point. For extra security, a new PIN can be generated. You can restore the default PIN at any time. Only the Administrator ("admin" account) can change or reset the PIN. Current PIN Shows the current value of the Access Point's PIN. Reset To WPS Default Restore the default PIN of the Access Point.
39 Generate New PIN Create a random number that is a valid PIN. This becomes the Access Point's PIN. You can then copy this PIN to the user interface of the registrar.
