Appendix A - Frequently Asked Questions (FAQs)
1. My EC keeps locking up and I need to cycle the DC power to it to bring it back. What is wrong?
There were a number of bugs discovered that would cause behavior such as this under certain
circumstances. To solve this problem, you need to upgrade your firmware to Version 3.06 or greater.
These issues have been resolved in this release. You can download the firmware from our Web site:
http://www.ydi.com/support/downloads.php
2. What do I need to do to flash upgrade the EC?
First off, check your current version. If it is 2.3 and earlier, then you will need to make sure the IP subnet
of your computer matches the IP subnet assigned to the EC, and you will also need to have a direct
Ethernet connection to it. (i.e., you are not trying to flash it wirelessly or on a heavily loaded network.)
To flash upgrade, download and install the latest client manager, be sure to uninstall any previous
versions before installing the new one. Select your EC in the scan window. Once it is connected and
initialized go to Utilities, and then go to Flash Utility. Make sure the latest version of firmware is displayed
in the box, then click the Upgrade Firmware button. A dialogue box should appear displaying progress.
NOTE: If you get a failure message, do not power cycle the EC. Instead just keep trying the upgrade until
it goes through. Change the IP address on your PC if necessary. If the power to the EC is removed
before the update is completed successfully, then it will reboot with trashed ROM image, which can only
be fixed at our facilities.
3. Why can I not log on Client Manager?
Only one Client Manager Login is allowed at a time. The Client Manager will not allow two users to log on
simultaneously.
4. Why does my EC seem to reduce its transfer speed sometimes?
Transfer Speed is reduced with Client Manager login (approx. 25%). You should not leave the Client
Manager logged in continually. The Client Manager was designed to configure and test the EC. It is not
recommended that you leave the Client Manager logged in during normal operations (a substantial
reduction in data transfer performance – approx. 25% – will be experienced when the Client Manager is
logged into an EC)
5. The settings of a Profile do not match what I previously entered.
If multiple ECs contain the same Profile Name, but different Profile settings, the Client Manager will inherit
the settings of the last EC to which it was connected.
6. Why do I lose my WEP keys?
Previously stored WEP keys will be lost when re-configuring an EC (via any wizard).
7. I’m entering information in a field of the Client Manager and the program does not recognize it.
What’s wrong?
When entering information into the various fields of the Client Manager, be aware that those fields are
case-sensitive (upper/lower-case).
8. The changes I implemented to my EC configuration do not show.
Any changes made to the configuration of an EC will not be stored in the EC until you save the changes
using the ‘Save Settings’ button.
9. How long does it take to an EC to re-associate with a new Access Point (or Wireless Link)?
The EC may take up to 15 seconds to automatically scan and re-associate with a new Access Point (or
Wireless Link) when the primary association has been lost due to marginal link conditions.
