74 Contents of Web InterfaceThe Web Interface application contains the following subjects:4.1 Info PageThe Info window displays the current setup status of the Wireless Ethernet Adapter..Communication Quality: Specifies the Communications Quality of the BasicService Set to which the station is currently connected.The value for the field of this record is based on signallevel and noise level measurements.Firmware Version. This indicates the Wireless Ethernet Adapter’s firmwareversion.
8Current setting of IP Address: The IP address of the wireless Ethernet adapter.Non-IP MAC Address: The MAC Address of Ethernet port that bridging toWireless Ethernet Adapter.
94.2 Wireless SettingsThe settings of the wireless device are displayed here, and you can edit some ofthese settings.Operating Mode: Infrastructure - is the default setting. Switch to Ad-Hoc modewhen communicating to another client device without thepresence of the Access Point.SSID: The SSID is also known as Service Set ID. This is the name of your wirelessnetwork. Only Wireless Ethernet Adapters and clients that share the sameSSID are able to communicate with each other.Channel: This is the channel that the Wireless Ethernet Adapter uses to transmitand receive information. The channel that you select here is restrictedto the channels that can be used within your Regulatory domain.
10Tx rate: The transmit rate identifies the preferred data transmission speed ofthe Wireless Ethernet Adapter. Transmissions at faster rates allow for higherdata throughput and quicker network response times. However, transmissionsat lower rates are usually more reliable and cover longer distances than thehigher rates.Access Point Density: When connecting to the Access Point, it is generallynecessary to specify an Access Point Density. Thisprovides some control over handoff of clients duringroaming between Access Points. Three values, Low,Medium, and High
114.3 Bridging TableThe table lists all of stations that are bridging with the Wireless Ethernet Adapter.
124.4 IP SettingStatic: Select Static (recommended) to assign the IP Address, the Subnet Mask and theGateway Address.DHCP: If the Wireless Ethernet Adapter is part of a network with a DHCP server,the DHCP server assigns the IP settings to the Wireless Ethernet Adapter for you.(This is not recommended because a DHCP-assigned IP Address will changefrequently, making the Wireless Ethernet Adapter impossible to configure.)Device Name: Assign the name of the Wireless Ethernet Adapter
13Allow Upgrade Uploads: Select this checkbox when performing upgrading firmware.
144.5 AdministrationChange Username and Password: You can use a password to prevent tampering withthe configuration of the Wireless Ethernet Adapter. By default, no username and passwordis required. However, if you choose to use a password, type in a password that is no morethan 15 letters in length. Re-enter the password in the next field, andclick Change Password for the change to take effect.Reboot Bridge: Click Reboot to restart the Wireless Ethernet Adapter.Reset to Factory Defaults: Click on Factory Reset to return all settings tothe Factory Default values. (Press and release the Reset button on the backof the unit to return the Wireless Ethernet Adapter to its factory default settings.)
154.6 SecurityWEP Enabled: The default setting is Disable. Encryption (WEP)—additional measureof security on your wireless network which can be achieved by usingWEP (Wired Equivalent Privacy) encryption. When an encryptedframe is received it will only be accepted if it decrypts correctly. Thishappens only if the receiver has the WEP Key used by thetransmitter. All devices on the network, and the Wireless EthernetAdapter, must share the same WEP selection – either Enable or DisableTo enable WEP Encryption, click on WEP Enable.
16WEP Key Length: The default Key Length is 64-bit. The WEP key is generated fromHexadecimal entries that are either 64 or 128-bit in length. (This isalso sometimes referred to as 40-bit or 104-bit encryption) Whenenabling encryption, select the Key Length, either 64 or 128-bit, andthen input the Hexadecimal digits. For 64 bit keys you mustenter 10 hex digits into the key fields, for 128 bit keys you mustenter 26 hex digits. If you leave the key field blank this means akey of all zeros.Note: Only the following alphanumeric characters are allowed in the entry, which is 0 to 9,atof.WEP Key to Use: Use the pull-down menu to select the WEP key. All devices on thenetwork must use the same key to communicate with one another.Deny Unencrypted Data: For additional security when WEP is enabled, select DenyUnencrypted Data. Data received without a WEP key isrejected when Deny Unencrypted Data is selected.Authentication Type. You may choose between Open System, SharedKey, and Both. The Authentication Type default is set toOpen System. Shared Key is when both the sender andthe recipient share a secret key. All points on your networkmust use the same authentication type. It is recommendedthat you use the default setting.
