23 User Manual for the Wireless Pocket USB
Chapter 6 Troubleshooting
1. Question: The product literature says this Wireless Pocket USB can operate at 54 Mbps.
Why do I see no more than 11 Mbps speed on my WLAN Configuration Utility status?
Answer: There are two possibilities. Firstly, if you are connecting to a 802.11b network, the
maximum 802.11b speed is 11 Mbps. Secondly, if your computer does not have a USB 2.0
port but rather a USB 1.1 port, the Pocket USB 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. PCs can be upgraded with optional add-on USB 2.0 adapters
that provide one or more USB 2.0 ports. Note that when you are using extension USB
cable to connect PC and the Pocket USB, the cable should be USB 2.0-compliant as well.
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.
2. Question: The Pocket USB’s LEDs are not lit?
Answer: Remove and reinsert the Pocket USB. Check the Windows device manager to see
if this device is recognized and enabled. Reload the Pocket USB’s software or try to install
it in a different port on your system.
3. Question: I can connect to an access point, but I cannot connect to other computers on the
network or the Internet?
Answer: Check to make sure that the access point is physically connected to the Ethernet
network. Make sure that the IP address and the Windows networking parameters are all
configured correctly by the connected AP. Restart your cable/DSL modem, router and
access point.
4. Question: Why my Pocket USB suddenly stops response, yet it was working well before?
Answer: When changing the AP’s configuration from non-WEP to WEP enabled while the
Pocket USB is connected, the device will enter infinite scan mode. Try to edit current
connection’s parameter or un-plug the device to stop this phenomenon.
