Solution |
| the AP did not receive a valid IP address via the DHCP. |
Ensure that the DHCP server is on and available on the VLAN/subnet to which the AP is connected. If the AP still fails to get a valid IP address, you can reboot it to see if the problem is resolved. |
| Unable to connect to the server. |
- Ensure that the server is running and is reachable from the network to which the AP is connected. If a firewall or a router has access Control Lists (ACLs) enabled between the AP and the server, ensure that traffic on UDP port 3851 is allowed.
- Use the IP-based server discovery method and ensure that you have correctly entered the DNS name, wifi-security-server , on the DNS server.
- Ensure that the DNS server IP addresses are either correctly configured, or are provided by the DHCP server.
- the AP might fail to authenticate with the server. In this case, an 'Authentication failed ' event is raised on the server. Refer to the event for recommended action.
