Troubleshoot Your Connection
If you cannot display the configuration utility, you can test the ability of the
PC to communicate with the access point by using ping. To use ping on a
PC running Windows:

Possible Cause of Failure
The most likely cause of connectivity failure is an incorrect IP address.
The Web browser is pointed to the wrong IP address. Or, your PC might be
configured with an IP address that is not in the same subnet as the access
point.
configured with an IP address that is not in the same subnet as the access
point.
DHCP is enabled on the Cisco AP541N by default. When a DHCP server is
enabled on your network and the access point is connected to the
network, the DHCP server replaces the default static IP address with a
DHCP server–assigned IP address. If this happens before you display the
Access Point Configuration Utility window, you must use the assigned IP
address to display the utility. If this happens during configuration, the
Access Point Configuration Utility will lose connectivity.

You can query the DHCP server for the new IP address or disconnect the
access point from the network and reset the device to use the static
default access point IP address by using the
