1 General Information WCB-G03H is a special 802.11g and 802.11b CardBus Card, which design to enable the wireless connection of MT841. WCBG03H is based on Conexant Javelin chipset that complied with IEEE 802.11g and IEEE 802.11b standard from 2.412~2.462GHz, and it can be used to provide up to 54Mbps for IEEE 802.11g, or 11Mbps for IEEE 802.11b to connect your wireless LAN.
z Supports wireless data encryption with 64/128-bit WEP for security z Supports infrastructure networks via Access Point and adhoc network via peer-to-peer communication z Integrated microstrip antenna z One-piece PC Card design to fully support PC Card type II defined mechanical and environmental stress conditions Support z WPA enhanced security Note: Environmental factors may negatively affect the wireless signal range and the performance of the WCB-G03H. 1.
The WCB-G03H Wireless Cardbus Adapter has two LEDs: POWER and ACTIVITY. POWER ACTIVITY Figure 1-2 LDEs LED Activity LEDs are flashing alternatively LEDs are flashing in unison LEDs are flashing in unison, but dimly What that means The WCB-G03H is searching for a wireless network connection. The WCB-G03H has made a valid wireless network connection, and there is activity on the link. The WCB-G03H has made a valid wireless network connection, but there is no activity on the link.
2 Wireless Basics Wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home or business. Strictly adhering to the 802.11b and 802.11g standards, our wireless family of products will allow you to access the data you want, when and where you want it. No longer will you be limited to one location or forced to run new wiring through your home or office. You will be able to enjoy the freedom that wireless networking delivers.
The advantages of Wireless LAN are many and varied and include: z Mobility − Productivity increases when people have access to data in any location within the operating range of the WLAN. Management decisions based on real-time information can significantly improve worker efficiency. z Low Implementation Costs – WLANs (Wireless Local Area Networks) are easy to set up, manage, change and relocate.
networks of thousands of users that allow roaming over a broad area.
3 Configuration Insert WCB-G03H into the slot of MT841, and then enter the web-based configuration of MT841. The layout of MT841 configuring page shown as below when you first log in. z The left part of the page is wizard column, and you can enter the web page of configuration or management through the hyperlink in wizard column. z The right part of the page is the practical domain of configuration and management.
Figure 3-4 Wireless Configuration The illustration of this page as below: z SSID: The SSID identifies members of Service Set. If the SSID is changed, all other devices on the wireless network must use the same SSID. z Channel: The available channel for the MT841 is depending on the local regulatory environment. Remember that all devices communicating with the device must use the same channel (and use the same SSID). Use the drop down menu to select the channel used for your wireless LAN.
the wireless adapter using one of the predefined keys. If network Security is not used, click None, otherwise select WEP or WPA-PSK. WEP Key: The MT841 offers 64, 128, or 256-bit z encryption with four keys available, select an encryption level from the drop-down menu on the right, and then enter the proper-length key. WPA-PSK: Wi-Fi Protected Access was designed to z provide improved data encryption, perceived as weak in WEP, and to provide user authentication, largely nonexistent in WEP.
4 WEP Glossary The following WEP parameters are be defined: Wireless Band − Select the environment you are configuring. Authentication − Select different authentication levels to manage the data transmission. Open System − Using an open system with WEP enabled means the access point and wireless stations encrypt only the data in each packet. WEP is not used for the purpose of authentication, that is, encryption does not prevent any station from associating with the access point.
Integrity Protocol) to change the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This insures much greater security than the standard WEP security. WEP − Wired Equivalent Privacy. You can select to [Enable] or [Disable] WEP. WEP Key Type − Select HexValue, and use Key Table for HexValue to define a HexValue. WEP Key Size − 64-bit, 128-bit, 152-bit length WEP encryption. Valid Key − Provides 4 groups of options respectively.
