[. . . ] Wireless-G USB2. 0 Flex Adapter User Manual (GWU513) ® ® Welcome Thank you for choosing IOGEAR® to serve your wireless needs. Soon, you will be sharing files or surfing the Internet wirelessly. We hope you will have as much fun using your IOGEAR® Wireless-G USB 2. 0 Flex Adapter, as we had designing it. Rest assured, your IOGEAR® Wireless-G USB 2. 0 Flex Adapter is built rock-solid to ensure maximum up-time for you to stay up-and-running. [. . . ] The Access Point mode, which is also known as the Infrastructure mode, allows you to communicate with a wired network via an access point. If you attempt to operate this mode, you must indicate the identical Network Name to make a communication with the intended access point. On the other hand, the Peer-to-Peer mode provides you with the so-called Ad-Hoc communication, which means each wirelessequipped computers within a group is able to connect with each other as an independent wireless LAN without the use of an access point. Each station within this Ad-Hoc network has to define the same Network Name. Configuration Program Controls Peer-to-Peer Channel: This command is only available while you are operating the Peer-to-Peer mode, the socalled Ad-Hoc mode. Specify the operating radio frequency channel from the pull-down menu if you are the creator of the wireless network. If you are the joiner, just configure the SSID and click Apply. Note that the available channels differ from country to country, and the channel number must be the same between the entries/stations within the range, so that each can communicate with each other. While in the Access Point mode, the channel number would be the same as the associated access point. Thus, there's no need to manually set up the value. Transmit Rate: This command allows you to indicate the rate of transferring the data packet from the associated access point or any nodes within the range. There are four options for you: Auto 1 or 2 Mb, 5. 5 Mb, 11 Mb, and Fully Automatic. Specify the rate from the provided options according to the speed of your wireless network, or you may simply choose Fully Automatic to set the best available rate according to the received signal quality and the capabilities of the associated access point or station. 32 Configuration Program Controls The Encryption Tab Click the Encryption tab to define the encryption settings for a specific profile. It offers you various options concerning the so-called WEP (Wired Equivalent Privacy) to maintain the secure management in a wireless LAN environment. See the explanations below for more details, and before making any activation of the new settings, click Apply. To undo the new settings, select the Cancel button. Note: Choosing the WEP Encryption command from the right-click menu of Wireless-G Configuration Tool tray icon will launch this tab too. Encryption (WEP security): If you choose Disabled from the pull-down list, you will have the Wireless-G USB Adapter communicated with all stations within the same networking community without any data encryption. Otherwise, two key lengths are offered: 64 bit and 128 bit. Specify a preferred one from the two, so that you may use the identical WEP key to make a communication 10 with the chosen access point. 33 Configuration Program Controls Create Keys Manually: Once you set the Encryption type as 64 bit or 128 bit, you may choose to edit WEP keys manually or create them via the passphrase of your wireless network. If you choose the Create Keys Manually option, you may directly enter up to 4 WEP keys for use in WEP encryption. To generate the WEP keys, please define the key entry method as Alphanumeric or Hexadecimal (for hexadecimal characters, only digits 0-9 and letters A-F are valid). Then edit the texts in the blank fields below, from Key 1 to Key 4, as the encryption codes. Note that these codes/keys shall be identical between the wireless nodes within the range and the access point only. Check the table right to find valid key length of each encryption type: 34 Use WEP Key: Indicate which WEP key you intend to apply to activate the WEP encryption from the pulldown menu. [. . . ] The associated access point also provides communication with the wired network. MAC Address ­ The MAC (Media Access Control) address is the serial number of your Network Interface card. It has been burnt into the chip and could not be changed. While a computer on the network is transferring data, its MAC address is also conveyed and attached to be part of the header of the data packets. 52 Glossary Roaming ­ Roaming is an ability to allow users from one cell (or BSS) to another without losing connection via a wireless device.
