Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the
other components are functioning properly.
Wireless Connection Problems
If wireless clients cannot access the network, check the following items before you
contact your local dealer for assistance:
◆ Be sure the access point and wireless clients are configured with the same
Service Set ID (SSID).
◆ Ensure that wireless clients are properly configured with the appropriate
authentication or encryption keys.
◆ If authentication is being performed through a RADIUS server, ensure that the
clients are properly configured on the RADIUS server.
◆ If authentication is being performed through IEEE 802.1X, be sure the wireless
users have installed and properly configured 802.1X client software.
In-Band Access
If the AP cannot be managed from the wireless access controller:
◆ Be sure to have configured the AP with a valid IP address, subnet mask and
default gateway.
◆ Check that you have a valid network connection to the AP and that the
Ethernet port that you are using has not been disabled.
◆ Check the network cabling between the access controller and the AP.
Out-of-Band Access
If you cannot access CLI through a serial port connection:
◆ Be sure you have set the terminal emulator program to VT100 compatible, 8
data bits, 1 stop bit, no parity and 115,200 Baud Rate.
