Troubleshooting Windows Problems
If you are having trouble accessing the connected serial device through Windows, ensure you
can ping the Serial Server using the DOS command PING ipaddress, where ipaddress is the IP
address of the Serial Server. If you cannot ping the Serial Server, you will not be able to access
the serial device.
If you are running COM port emulation software and the software reports an error, verify that the
correct serial/IP COM port is being used when the application runs. Verify that your application’s
COM port settings have been changed to use the Serial/IP COM ports.
Troubleshooting Wireless Configuration Problems
Verify that your PC’s wireless adapter and/or access point is configured properly – note the
settings, paying special attention to the wireless mode, SSID or network name, WEP or security,
and IP address settings so you can configure your Serial Server to the same wireless settings.
Make sure you have a good wireless signal from your PC and from the Serial Server, that the
Serial Server is within range (90 meters or 300 feet), and that it is away from metal objects and
other devices that generate radio signals (like Bluetooth devices, cordless phones, and
microwave ovens).
Make sure your computer is set to infrastructure mode if you are connecting through an access
point, or ad-hoc (802.11) if you are connecting to the Serial Server without an access point. See
the documentation for your wireless adapter for details.
If you want to use WEP encryption or password protection for your wireless network, and your
wireless adapter or access point normally uses a password or passphrase instead of WEP, it
should allow you to enter 0x followed by a 10-digit key (for 40-bit or 64-bit WEP) or 26-digit key
(for 128-bit WEP) in hexadecimal format (0-9 or A-F).
If you are experiencing slow performance or are having intermittent problems connecting, try
changing the RF channel of your wireless network. The RF channel can be changed via the
ExtendView Utility or the web browser configuration utility for the Serial Server. See your
wireless adapter and/or access point documentation for more information. When changing the
RF channel, it is recommended that you select a channel that is at least three channels lower or
higher than any other wireless networks within range.
