Problem Solution
I always have poor link quality
and low signal. Do the following to achieve better link quality
and stronger signal:
• Keep the device away from microwave
ovens and large metal objects to avoid
radio interference.
• Shorten the distance between the device
and the AP/station.
The throughput seems slow. • Avoid placing the device behind a metal
object. Clear obstacles between the AP
and the device.
• Try moving the client closer to the
WebSTAR DPW939 USB Wireless LAN
Adapter to see if the throughput
increases.
• Consider adding a second WebSTAR
DPW939 USB Wireless LAN Adapter to
implement roaming.
Why do I get the warning “Hi-
Speed USB Device Plugged
Into Non-Hi-Speed USB Hub”
message when I connected
the WebSTAR DPW939 USB
Wireless LAN Adapter to the
USB port? This warning message appears when you
plug the WebSTAR DPW939 USB Wireless
LAN Adapter to a USB 1.1 port. Select from
one of the following options according to your
operating system:
• For Windows XP users, you need to
upgrade your OS to Service Pack 1 to
convert your USB ports to USB 2.0.
• For Windows 2000 users, you must install
Service Pack 4 in order to convert your
USB ports into USB 2.0. You can
download these service packs from the
Windows Update Web site
(www.windowsupdate.microsoft.com).
When I remove the wireless
adapter from my computer
running Windows 98SE, my
system becomes very slow
and stops responding. This is a limitation with computers equipped
with Intel/NVIDIA USB 2.0 controller and
running the newest OrangeWare USB 2.0
driver.
