Wi-Fi Configuration view - Niagara 4.15
The Wi-Fi Configuration view is the primary view for configuring Wi-Fi communications on both the JACE-8000 and the JACE-9000 controllers. The view includes tabs for configuring the controller to run in both Client mode and Access Point mode. However, a controller unit cannot perform in both modes at the same time.
The topics that follow provide additional details about the JACE-9000 Wi-Fi Configuration view in Niagara 4.15 Workbench: .
The information in this view is organized in three major groups: Host Configuration, Client Mode tab, Access Point Mode tab. Values are shown in each view but are editable only when appropriate, based on the current active Wi-Fi state (Enabled: true or false) and mode (Switch Position), as selected and shown in the Host Configuration group properties.
Host Configuration properties
The Host Configuration property group is located at the top of the Wi-Fi Configuration view. These properties are described in the following table.
| Property | Value | Description |
|---|---|---|
| Wi-Fi Enabled | true, false (default) | The true option enables Wi-Fi and the false option disables Wi-Fi on the connected controller. Any change in this value requires a reboot to implement. |
| Switch Position | Off, Client, Access Point, Access Point Controlled |
Note: There is no physical "switch" on the JACE-9000.
|
| Status | read-only field reports a current status | Values indicate current status, including the following steady and transitional states.
|
| Country Code | read-only field displays device Country Code | Based on your controller's SKU and Region, as described in Regions, SKUs, and Country Codes |
Current Wi-Fi states
| Current Wi-Fi State | Condition | Additional Notes |
|---|---|---|
| Stopping | Indicates that Wi-Fi processes are stopping. | This is the result of toggling the Wi-Fi Enabled control from true to false in the platform's Wi-Fi Configuration view, or an access point Inactivity Timeout occurred. In the case of an inactivity timeout, the next state will be Inactivity Timeout after which the Wi-Fi connection stops. In all other cases, the next state will be Stopped. |
| Stopped | Indicates that the Wi-Fi drivers are not loaded and no Client or Access Point mode processes are running. | The Wi-Fi LED on top of the unit should be in blinking mode. See JACE-9000_WiFi_Controls_and_Indicators.html#reference-3580__table-led-mode-status. |
| Failed | read-only field reporting a process failure. |
Reports that a Wi-Fi process (either
Client or Access Point) was not able to successfully complete. This
usually indicates an invalid Wi-Fi configuration. A Failed state kicks off an attempted shutdown of the Wi-Fi processes and
drivers, after which the state should transition to Stopped.

Client Mode Wi-Fi states
The following current Wi-Fi states are specific to Client mode.
| Type | Value | Description |
|---|---|---|
| Client Supplicant Running | Indicates that Client mode is running but not active. | This status displays when Client mode is inactive and not connected to an Access Point. |
| Client Running | Reports that the adapter is up and the IP assigned. | Client successfully established the connection with Access Point. |
| Client Scanning | Indicates that the Client mode Wi-Fi adapter is looking for an access point to connect to by scanning available frequencies. | This can happen if the Wi-Fi network (ssid/password, etc) is not configured correctly or is unavailable because the access point is off or out of range. |
| Client Trying to Associate | Indicates that a configured access point has been located, and the supplicant is trying to associate with the access point. | If the Allow List is configured in the access point, the mac address of this client adapter must pass the list filters. |
| Client Negotiating | Indicates that the Client mode supplicant is negotiating capabilities and credentials with the access point. | If successful, the next transition will be to Sta Running. |
| Client Association Success | Indicates that the Client has successfully associated with an access point. | The Client and access point begin a four-way handshake to validate credentials and establish common security protocol suites (see "Sta Negotiating"). |
| Client Disconnected | Reports a normal state transition on Client mode startup. | It is normal to see this during Client mode startup, but should transition to other states. If no configured access points are available, the connection does not progress past this point. Every 15 seconds, the network database is reloaded, so that configuration changes made during this state are picked up. |
| Client Fault | Indicates tha the Client mode is not currently capable of running. | This state displays when a client process encounters a faulty or unknown state. This state may also result from configuration errors or a failure in the CC and SKU validation process. |
Access Point mode Wi-Fi states
The following current Wi-Fi states are specific to Access Point mode.
| Type | Value | Description |
|---|---|---|
| Access Point Starting | Reports that the Access Point mode is enabled in the Wi-Fi Configuration view. | This starts the Wi-Fi driver, which adds a wlan0 adapter, brings the adapter up and assigns an IP address to it, starts Hostapd, and starts the Dhcp server on the adapter. This state can only be entered from the Stopped state. |
| Access Point Running | Reports that the adapter is up and the IP address assigned. | The Hostapd started and the Dhcp server started on the adapter. |
| Inactivity Timeout | In Access Point Controlled mode, a non-zero Inactivity Timeout value is used to provide Access Mode capability. If, for the specified amount of time, no clients are connected or attached, the adapter is shut down in this state. | Inactivity timeout is only used in Access Point Controlled mode.
To restart the Wi-Fi adapter after an Inactivity Timeout shutdown, you must press the Wi-Fi button on the controller. Timed access restarts using the current Inactivity Timeout setting. |
| Access Point Fault | Reports that there is a fault, unknown state or configuration error. | This state indicates that the service is not started because Wi-Fi properties are not correctly configured, service is not enabled or in some other fault state. |
