The D-Link DWL-G122 AirPlus G™ High Speed 802.11g USB Wireless Adapter is a device designed to provide wireless connectivity for desktop or laptop computers. It operates on the 802.11g standard, offering high-speed wireless communication, and is also backward compatible with 802.11b networks.

Function Description:

The primary function of the DWL-G122 is to enable a computer to connect to a wireless network. It acts as a wireless client, allowing the computer to communicate with an 802.11b or 802.11g Access Point in Infrastructure Mode, or directly with another 802.11b or 802.11g wireless adapter in Ad-Hoc (Peer-to-Peer) networking mode. The device plugs into an available USB port on the computer, providing a convenient way to add wireless capabilities.

Important Technical Specifications:

• Wireless Standard: High Speed 802.11g, backward compatible with 802.11b.
• Interface: USB (Universal Serial Bus).
• Frequency: Operates in the 2.4GHz band.
• Data Rates (TxRate): Supports up to 54.0 Mbps. The default setting is "Auto," meaning the adapter automatically determines the optimal TxRate based on the distance from the access point.
• Channel: By default, the channel is set to 6. The DWL-G122 can automatically adjust its channel depending on the Access Point.
• SSID (Service Set Identifier): The name assigned to the wireless network. The factory SSID setting is "default."
• Wireless Mode: Supports "Infrastructure" mode (for connecting to an Access Point) and "Ad-Hoc" mode (for peer-to-peer networking). The factory setting is "Infrastructure."
• Encryption: Supports WEP (Wired Equivalent Privacy) when encryption is enabled. Key Length options include "64 bits (40+24)" and "128 bits (104+24)" (though only 64 bits is explicitly shown in the screenshot, the manual implies more options for key length and format). Users can specify the Key Index (1-4) and enter ASCII or hexadecimal digits for the encryption key.
• Authentication: The default authentication mode is "Open Authentication."
• IEEE 802.1X: When encryption is enabled, users have the option to specify the level and key format for IEEE 802.1X, including Key Index (1-4) and entering ASCII or hexadecimal digits.
• LED Indicator: Features a Link/Power LED. This LED indicates proper installation in the computer (Link) and blinks when data is being transmitted through the wireless connection (Power).
• Antenna: Integrated antenna for wireless connectivity.
• System Requirements:
  • Operating Systems: Windows XP, Windows 2000, Windows Me, Windows 98SE.
  • Processor: At least a 500 MHz processor.
  • Memory: At least 62 MB of memory.
  • USB Port: An available USB port.
  • USB Controller: A properly installed and working USB Controller.
  • Wireless Network: An 802.11b or 802.11g Access Point (for Infrastructure Mode) or another 802.11b or 802.11g wireless adapter (for Ad-Hoc mode).

Usage Features:

• Easy Installation: The device comes with a CD-ROM containing drivers, a manual, and warranty information. The installation process is guided by an InstallShield Wizard.
• Driver Installation: Users are instructed to install the driver software from the CD-ROM before plugging the DWL-G122 USB Adapter into the computer. This is a critical step to ensure proper functionality.
• Configuration Utility: After successful installation, the D-Link AirPlus DWL-G122 Configuration Utility automatically starts and appears as an icon in the system tray. This utility provides a graphical interface for managing wireless settings.
  • Status Monitoring: The utility displays the MAC Address of the associated Access Point, current SSID, frequency, wireless mode, and encryption status.
  • Connection Information: Shows whether the device is connected or authenticated, the current TxRate, and the channel in use.
  • Signal Quality and Strength: Graphically represents the wireless signal quality and strength between the access point and the adapter, with a percentage indicator.
  • Packet Count: Provides a graphical display of transmitted and received data packets.
  • Advanced Configuration: Allows users to modify settings such as SSID, Wireless Mode (Infrastructure/Ad-Hoc), Data Encryption (Disabled/WEP), Authentication (Open Authentication), Key Length, and IEEE 802.1X settings.
• Portability: The compact USB adapter design makes it suitable for both desktop and laptop computers. A cradle is included for potentially better placement or stability.
• FCC Compliance: The device complies with FCC Part 15 rules for Class B digital devices, designed to provide reasonable protection against harmful interference. It also includes an FCC Radiation Exposure Statement, indicating compliance with exposure limits for an uncontrolled environment and specifying that it is SAR-evaluated and authorized for use in laptops/notebooks. The device is limited to channels CH1-CH11 by specified firmware controlled in the USA.

Maintenance Features:

• Driver Updates: While not explicitly detailed as a "maintenance feature," the presence of drivers on a CD implies that D-Link may release updated drivers for improved performance or compatibility, which would be a form of software maintenance.
• Troubleshooting: The Quick Installation Guide itself serves as a primary troubleshooting resource for initial setup. The FCC statement also provides general troubleshooting advice for interference issues (reorienting antenna, increasing separation, connecting to a different circuit).
• Reseller Contact: If any items are missing from the package, users are advised to contact their reseller.
• Software Installation Warnings: The installation process includes warnings about unsigned drivers (for Windows 2000/XP) and the importance of installing drivers before connecting the hardware, which helps prevent system instability.
• System Restart: A system restart is required after driver installation to finalize the setup, ensuring all changes are applied correctly.
