How to Update

1. Insert the Easy Wireless Stick for which you want to update the firmware into the computer’s USB port.

If the [AutoPlay] screen appears, close it. If the software starts automatically, exit it.

2. Run the “FirmUpdateTool_uw100_****.exe” (example: FirmUpdateTool_uw100_4008.exe)
firmware update tool that was generated after downloading and uncompressing.

If the [User Account Control] dialog box (i.e., “Do you want to allow the following program
from an unknown publisher to make change to this computer?” message) appears, select [Yes].

3. Verify the version number displayed in the update confirmation screen, and click the [Update] button to start the firmware update.

• The overwrite process takes about 4 minutes.
• After overwrite starts, all buttons in the update tool screen are disabled.

Do not remove the Easy Wireless Stick from the USB port or attempt to remove the [EasyWS] CD drive while overwrite is in progress.

The Easy Wireless Stick will restart during the firmware overwrite process. Therefore, depending on your computer’s AutoPlay settings, the [AutoPlay] screen may appear, Explorer may open and the contents of the [EasyWS] folder may be displayed, or the PDF file in the [EasyWS] folder may open. In such cases, close the windows or files, and wait for update to complete.

4. When overwrite is complete, the [OK] button is enabled.
Click the [OK] button to exit the update tool.

5. Check the firmware version of the Easy Wireless Stick and verify that update has been performed properly.
(How to confirm the version)


• If the firmware overwrite fails due to, for example, the Easy Wireless Stick being removed during the process, follow steps 1 to 3 in
“How to Update” and try to update again.
(This only applies when updating from firmware Ver. or later.)
