If the Ethernet LEDs do not light when the Ethernet connection is made, check the following:

Make sure that the Ethernet cable connections are secure at the wireless controller and 
at the hub, switch, or router.

Make sure that power is turned on to the connected hub, switch, or router.

Be sure that you are using the correct cables.

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 connection between the computer and the wireless controller as 
described in the previous section (see 

).

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 has a 
static IP address of 192.168.0.210 and a subnet of 255.255.255.0.

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 has been 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 

204.

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.
