Rear Panel 4 LAN Port 10/100/1000Mbps Power Jack DC input 3.3 Top View 3.4 Bottom View 15 3.3 Installation Considerations The TEW-680MB Media Bridge allows you to access your network by using a wireless connection from virtually anywhere within its operating range. Keep in mind 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-680MB and other network devices to a minimum - each wall or ceiling can reduce your wireless products 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. 16 11. Using the Configuration Menu Whenever you want to configure your TEW-680MB, you can access the Configuration Menu through your PC by opening the Web-browser and typing in the IP Address of the TEW-680MB . The TEW-680MBs default IP Address is http://192.168.10.110

Open the Web browser.

Type in the IP Address of the Bridge (http:// 192.168.10.110) If you have changed the default IP Address assigned to the TEW-680MB, make sure to enter the correct IP Address.

Select admin in the User Name field. 17

Password is admin.

Click Login In. 4.1. Network 4.1.1 LAN Setting LAN Connection Type Choose "Static IP (fixed IP)" if your router does not support DHCP or if for any other reason you need to assign a fixed address to the AP. In this case, you must also configure the following fields. IP Address The IP address of this Media Bridge on the local area network. Assign any unused IP address 18 in the range of IP addresses available from your network. For example, 192.168.10.110 Subnet Mask The subnet mask of the local area network. Default Gateway The IP address of the router on the local area network. 4.2 Wireless 4.2.1 Profile Create a custom connection to a specific wireless network. Use this option to make custom profiles and store new profile for later use. Configure the setting to connect to a wireless network, selection option for network type, SSID, and wireless security. The profile can be edited, deleted and made active from this option. There are several ways to connect to your wireless network, go through the setup wizard, add a new profile or search using site survey feature. 19 When adding an Profile, please make sure your information matches your existing wireless network. 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. No encryption. None WEP (Open or Shared) A method of encrypting data for wireless communication intended to provide the same level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American 20 Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily. A default key is selected for use on the network. Key Length 64-bit 128-bit Hex 10 characters 26 characters ASCII 5 characters 13 characters WPA-Personal or WPA2-Personal 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 (AES or TKIP type) 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. 21 4.2.2 Link Status The Status page shows the settings and current operation status of the Station. 4.2.3 Site Survey Use the Site Survey tool to search for wireless networks around the TEW-680MB bridge. Click on the Scan button to search for wireless network to join. From this window, you can also add the selected network to your profile by clicking the Add Profile button. To connect to the desire wireless network, click on the Connect button to join a wireless network from this site survey window. 22 23 4.2.4 Statistics View the current operating status of the TEW-680MB, see the Transmit and Receive data. 24 4.2.5 Advance Use this setting to adjust the wireless environment.
