ProSAFE Wireless Controller
Troubleshoot the Web Management Interface
If you are unable to access the wireless controller’s web management interface from a
computer on your local network, try to isolate the problem. You can most likely solve the
problem by following the suggestions that are described in the following sections.
Check the Ethernet Cabling
Check the Ethernet connection between the computer and the wireless controller as
described in the previous section (see Ethernet Port LEDs Are Not Lit).
Check the IP Address Configuration
Make sure that your computer’s IP address is on the same subnet as the wireless controller.
If you are using the recommended addressing scheme, make sure that your computer is
assigned a static IP address of 192.168.0.210 and a subnet of 255.255.255.0.
Note: If your computer’s IP address is shown as 169.254.x.x:
Windows and Mac operating systems generate and assign an IP
address if the computer cannot reach a DHCP server. These
autogenerated addresses are in the range of 169.254.x.x. If your IP
address is in this range, check the connection from the computer to
the wireless controller and reboot your computer.
If the wireless controller’s IP address changed and you do not know the current IP address,
reset the wireless controller’s configuration to factory default settings. The factory default IP
address of the wireless controller is 192.168.0.250. For more information, see Reboot the
Wireless Controller on page 259.
If you do not want to revert to the factory default settings and lose your configuration settings,
you could use one of the following methods to discover the IP address of the wireless
controller:
• Reboot the wireless controller and use a sniffer to capture packets sent during the reboot.
Look at the ARP packets to locate the wireless controller’s LAN interface address.
• Run an IP scanner application in your network to discover the IP address of the wireless
controller.
• Connect a serial cable between a computer and the wireless controller, and use the
ifconfig command to discover the IP address of the wireless controller.
