7  Introduction The TEW-637AP is an 802.11n (draft 2.0) high-performance, wireless AP that supports high-speed wireless networking at home, at work or in public places.    Unlike most Access Points, the TEW-637AP provides data transfers at up to 300 Mbps when used with other 11n products. This AP is backwards compatible with 802.11b/g products. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 802.11g’s speed when you mix 802.11n (draft2.0) and 802.11g devices, but you will not lose the ability to communicate when you incorporate the 802.11n (draft 2.0) into your 802.11g network. You may choose to slowly change your network by gradually replacing the 802.11g devices with 802.11n (draft 2.0) devices.    Features ¾  Supports IEEE 802.11n (draft 2.0) & 11b/g 2.4GHz wireless Local Area Network (WLAN) application  ¾  2.412 to 2.484GHz frequency band operation ¾  Compliant with IEEE 802.3 & 3u standards ¾  Support OFDM and CCK modulation   ¾  Data rates of 1,2.5.5,6,9,12,18,24,36,48,54Mbps and 802.11n (draft 2.0) offering up to 300Mbps. ¾  Support one LAN port ¾  Support WEP & WPA security ¾ Support two external antennas

LAN LED A solid light indicates a connection to a Router on the LAN port. This LED blinks during data transmission.  POWER LED A solid light indicates a proper connection to the power supply.  WPS Button Press the button to enable WPS function.      Installation Considerations  The TEW-637AP AP 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-637AP 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.

Page 21   Radio On/Off
Page 22 Press this button to toggle radio On/off.  Wireless Mode If all of the wireless devices you want to connect with this Access Point can connect in the same transmission mode, you can improve performance slightly by choosing the appropriate "Only" mode. If you have some devices that use a different transmission mode, choose the appropriate "Mixed" mode.  Wireless Name (SSID) When you are browsing for available wireless networks, this is the name that will appear in the list (unless Broadcast Network Name is set to Disable, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured network name.  Multiple SSID # This Access Point support multiple SSID function, you can assign three more SSID for this device. Broadcast Network Name (SSID) This option allows you to hide your wireless network. When this option is set to enable, your wireless network name is broadcast to anyone within the range of your signal. If you're not using encryption then they could connect to your network. When this mode is disabled, you must enter the Wireless Network Name (SSID) on the client manually to connect to the network.  Frequency (Channel) A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network.  WDS Mode When WDS is enabled, this access point functions as a wireless repeater and is able to wirelessly communicate with other APs via WDS links. Note that WDS is incompatible with WPA -- both features cannot be used at the same time. 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 number.  Operating Mode If you have both 11g and 11n client devices included on your wireless network at the same time, you should choose Mixed Mode. And if you only have 11n client devices on your wireless network, you can choose Green Field to enjoy high throughput. Channel Bandwidth The "20/40” MHz option is usually best. The other option is available for special circumstances.  Guard Interval Using “Auto” option 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.  MCS
Page 23 This parameter represents transmission rate. By default (Auto) the fastest possible transmission rate will be selected. You have the option of selecting the speed if necessary.  Reserve Direction Grant (RDG) Disable or enable reserve direction grant. Default is enabled. Extension Channel When 20/40 channel bandwidth has been chosen, you should select extension channel to get higher throughput.
Page 24 Wireless Advanced     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. Data Beacon Rate (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
Page 25 awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255.  Fragment Threshold This setting should remain at its default value of 2346. Setting the Fragmentation value too low may result in poor performance.  RTS Threshold This setting should remain at its default value of 2347. If you encounter inconsistent data flow, only minor modifications to the value are recommended.  Short Preamble Use to synchronize communication timing between devices on a network. Disable by default. Short Slot Enable or disable short slot. Default is enabled. Tx Burst Enable or disable Tx burst. Default is enabled. Pkt_Aggregate Enable or disable Pkt aggregate. Default is enabled. WMM Capable Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless connection.  APSD Capable Enable or disable APSD capable. Default is enabled.
Page 26 Wireless MAC Filter  The MAC address filter section can be used to filter network access by machines based on the unique MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the network adapter.     Policy Three policies can be selected - Disable, Allow All & Reject All.
