ProSAFE Wireless Controller
Resolve Connection Problems
If the Power LED of an access point blinks amber, the access point lost its connection to the
wireless controller. In this situation, check the network connectivity between the access point
and the wireless controller.
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 issues, 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 is assigned a unique IP address.
If the network does not include a DHCP server or if the access point cannot reach the DHCP
server, the access point remains in the Connecting state, attempting to obtain an IP address.
If the network does not include a DHCP server, configure one on the wireless controller (see
Manage the DHCP Server on page 106). When a DHCP server becomes available, the
access point can transition from the Connecting state to the Connected state.
If you assign a static IP address to the wireless controller and then use the web management
interface of a discovered access point to configure a static IP address for the access point
and enter the wireless controller’s static IP address, the access point attempts to reach the
wireless controller only at the provided static IP address. If the IP address of the wireless
controller changes, the access point can no longer reach the wireless controller. In such a
situation, reset the access point to factory default settings. Doing so removes the static IP
address of the wireless controller from the access point configuration.
Network Performance and Rogue Access Point Detection
When rogue access point detection is enabled, access points intermittently go off channel for
short periods, which can affect network performance. The default rogue access point
detection interval is 30 minutes. This interval is not configurable.
Use the Diagnostic Tools on the Wireless Controller
As part of the diagnostic functions on the wireless controller, you can ping a managed access
point from the wireless controller and trace its route from the wireless controller. You can also
remotely view the console debug logs of a managed access point and capture its WiFi
packets in the network.
The following sections describe the diagnostic functions:
• Ping an Access Point on page 367
• Trace a Route to an Access Point on page 368
• View the Console Debug Logs of an Access Point on page 369
• Capture WiFi Packets on page 371
