When the date shown is January 1, 2000, the wireless controller has not yet successfully 
reached a network time server. Verify that the wireless controller can reach the Internet. If 
you have completed configuring the wireless controller, wait at least five

 

minutes and check 

the date and time again.

If you encounter access point discovery or connection problems, the information in this 
section might help you to resolve these problems.

If the wireless controller does not discover any or all access points, check the configuration of 
the wireless controller and access points.

For all access points, check the following:

Make sure that the wireless controller is connected to the LAN (see 

Make sure that you have entered the correct IP range if the access points function in 
different VLANs, are behind an IP subnet, or are already installed and working in 
standalone mode (see 

120).

Make sure that the access points run at least their initial firmware release or a newer 
version. For firmware requirements, see 

16.

For local access points that are installed across a Layer 3 network, check the following:

Verify that access points that are already installed and working in standalone mode have 
SSH and SNMP enabled (which is the default setting). 

Make sure that UDP port number 7890 is unblocked in the firewall.

Except for access points in factory default state that are in the same Layer 2 network, if 
more than one access point has the same IP address, only one of them is discovered at a 
time. You must add the access point to the managed list, change its IP address, and run 
discovery again to discover the next access point with that IP address.

Make sure that DHCP option 43 (vendor-specific information) is enabled on an external 
DHCP server. (Specifying an internal DHCP server on the wireless controller 
automatically enables DHCP option

 

43 with the IP address of the wireless controller.)

120.

When an access point is converted from standalone AP mode to managed AP mode, its 
static IP address is changed to an IP address that a DHCP server has issued, either a DHCP 
server in the network or a DHCP server that is configured on the wireless controller. This 
change occurs to ensure that each managed access point has a unique IP address.
