Whenever you experience problems with the wireless LAN connection between the YP-100
and the computer, check the following points first.
Check the following on the computer.
• Did you disable “Network Connection” before connecting the YW-2 wireless LAN
adapter to your computer’s USB port?
On the Windows Control Panel, click “Network Connections” (“Network and Dial-up
Connection” in the case of Windows 2000). If you see “Local Area Connection”,
“Wireless Network Connection” or “Network Bridge” on the window that appears, right-
click the icon and then click “Disable”.
• Is a wireless LAN utility other than Wireless Connection (which comes with the
YP-100) running?
If so, shut down the other utility.
Check the following on the YP-100.
• Is the same connection profile selected on the computer and on the YP-100?
Wireless LAN connection is not possible when different connection profiles are selected
on the computer and the YP-100 (such as “Manual Connection 1” on the computer and
“Simple Connection 1” on the YP-100). Make sure the same connection profile is
selected on both.
Also check the following.
• Are the YP-100 and computer too far apart or are they separated by a wall or
other barrier?
Try moving the YP-100 and computer so they are closer to each other.
• Is a microwave oven or a Bluetooth device being used nearby?
Operation of a device that uses the 2.4 GHz frequency band (which is the same
frequency band as the IEEE802.11b wireless standard used by the YP-100) in the
vicinity of the YP-100 can cause radio interference, resulting in a wireless communication
error. Avoid using the nearby microwave oven or Bluetooth device when performing YP-
100 wireless LAN communication.
If the above countermeasures do not resolve your problem, try the following depending on
the problem you are experiencing.
