The product literature says the WG121 can operate at 54 Mbps. Why do I see no more than 11 Mbps speed on my WG121 Smart Configuration Utility status line?

Answer: If you are connecting to an 802.11b network, the maximum 802.11b speed is 11 Mbps.

The product literature says the WG121 can operate at 54 Mbps. Why do I see no more than 14 Mbps speed on my WG121?

Answer: If your computer does not have a USB 2.0 port but rather a USB 1.1 type port, the WG121 will be limited to the maximum speed of the USB 1.1 port. USB 1.1 port maximum speed is 14 Mbps whereas the maximum speed of a USB 2.0 port is 480 Mbps. PC computers can be upgraded with optional add-on USB 2.0 adapters that provide one or more USB 2.0 ports.

Note: Even though you are using USB 2.0 controller, please make sure that you are using the correct driver for USB 2.0.
For the Windows XP, you need to upgrade your system to Service Pack 1 in order to utilize the USB 2.0 port.
For the Windows 2000, you need to upgrade your system to Service Pack 4 in order to utilize the USB 2.0 port.

Maximum wireless signal rate derived from IEEE Standard 802.11 specifications. Actual data throughput will vary.
Network conditions and environmental factors, including volume of network traffic,
building materials and construction, and network overhead, lower actual data throughput rate.
