The factory default login name is admin, and the password is password. Make sure that Caps Lock is off when entering this information. If the wireless controller does not save changes that you make in the web management interface, check the following: • When entering configuration settings, be sure to click the Apply button before moving to another tab or screen, or your changes are lost. • Click the Refresh or Reload button in the web browser. It is possible that the changes occurred but that the old settings remain in the web browser's cache. After you upgrade the firmware, if the browser does not display the latest features of the web management interface, clear the browser's cache, and refresh the screen.

ProSAFE Wireless Controller WC9500

Check the Internet Browser

If the Ethernet cabling and IP address configuration are fine, the Internet browser might

prevent you from accessing the web management interface. Check the following:

•

Make sure that you are using the http://address login rather than the https://address login.

•

Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are using

Internet Explorer, click the

Refresh

button to be sure that the Java applet is loaded.

•

Try quitting the browser and launching it again.

•

Make sure that you are using the correct login information. The factory default login name

is admin, and the password is password. Make sure that Caps Lock is off when entering

this information.

If the wireless controller does not save changes that you make in the web management

interface, check the following:

•

When entering configuration settings, be sure to click the

Apply

button before moving to

another tab or screen, or your changes are lost.

•

Click the

Refresh

Reload

button in the web browser. It is possible that the changes

occurred but that the old settings remain in the web browser’s cache.

After you upgrade the firmware, if the browser does not display the latest features of the web

management interface, clear the browser’s cache, and refresh the screen.

Troubleshoot a TCP/IP Network Using the Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request

packet to the designated device. The device then responds with an echo reply. You can

troubleshoot a TCP/IP network by using the ping utility in your computer.

You can ping the wireless controller from your computer to verify that the LAN path to your

wireless controller is set up correctly.



To ping the wireless controller from a computer running Windows:

From the Windows toolbar, click the

Start

button, and select

Run

In the field provided, type

ping

followed by the IP address of the wireless controller, as in

this example:

ping 192.168.0.250

Click the

button.

A message like the following one displays:

Pinging <IP address> with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
