Access Point Mode tab
The figure shown here shows the Access Point Mode configuration properties with the controller’s secondary LAN port configured for DHCP.
Figure 3. WiFi Configuration view, Access Point Mode tab
| Property | Value | Description |
|---|---|---|
| Adapter name | tiw_sap0 (default) | Read only value. |
| Adapter IPv4 Address | IP address | This sets the IP address of the WiFi adapter. A client uses this to make an IP connection over WiFi while the unit is functioning as an Access Point. |
| Adapter IPv4 Netmask | IP address | This sets the netmask of the WiFi adapter. |
| Type | Value | Description |
|---|---|---|
| Default Lease Time | 6 hours (default) | Fixed duration (in hours, minutes, and seconds) for a DHCP IP address lease, before it expires the lease must be renewed. |
| Max Lease Time | 12 hours (default) | Maximum duration (in hours, minutes, and seconds) for a DHCP IP address lease. |
| Subnet | address | The subnet of IP addresses assigned by the DHCP server.
CAUTION: Configure this to assign addresses on a different subnet than that used in either of the controller’s other LAN configurations, otherwise the ports will not function correctly. |
| Netmask | number | The Netmask of IP addresses assigned by the DHCP Server. |
| Client Range Low | address | Lowest IP address for the range. The order of assigning IPs from the Access Point DHCP is indeterminate.
NOTE: The adapter IP should be in the same subnet, but not in the range of addresses defined here. |
| Max Number of Clients | 11 (default) | Maximum number of WiFi clients that can attach at a given time (maximum limit is 16). |
| Type | Value | Description |
|---|---|---|
| Ssid | titan (default) | Service Set Identifier is a unique alphanumeric identifier. Sets the name for this access point. Replace default name with
a unique, meaningful network name.
NOTE: It is important to change the default value to a unique name to avoid having multiple units with the same SSID in a particular area. |
| Broadcast SSID | enabled (default), disabled | If enabled, periodically broadcasts WiFi signal so that devices can detect and connect.
If disabled, the SSID is "hidden" and not discoverable, and a client must be manually configured with the correct SSID which matches the JACE's Ssid field above. |
| Passkey | text | Sets a password that a client must enter to connect to this network. Strong password required |
| Wpa Mode | WPA WPA2 WPA WPA2 (default) |
WiFi security protocols and security certification programs. WPA WPA2 will accommodate most devices. Devices with older network cards may only work with WPA security. |
| Key Management Algorithms | WPA-PSK (default) WPA-EAP WPA-PSK WPA-EAP |
Methods of authentication key distribution and the encryption protocols that protect passwords via encryption using either a pre-shared key and/or an authentication server. |
| Pairwise Cipher Suites | TKIP CCMP TKIP CCMP (default) |
Encryption protocol options. TKIP CCMP will accommodate most devices. |
| Inactivity Timeout (minutes) | 10 (default) | Sets a limit on the amount of time a client connection can be inactive. On reaching the Timeout limit, the WiFi adapter is
shutdown completely. To restart it you must move the WiFi Selector Switch on the unit to “OFF”. Once the WiFi Current State
shows “Stopped”, move the WiFi Selector Switch back to “ACC”.
Note, if the intended WiFi usage is for tool connectivity, then set this value to some small number of minutes. If the intended WiFi usage is for field bus integration, then set this value to “0” to disable the Timeout functionality. CAUTION: An Access Point represents a potential target for cyber attack. Leaving the Access Point disabled by default is a security best practice. |
| Whitelist | list | Allows you to configure the access point with a range of device MAC addresses that can connect. |
| Enable Whitelist | disable (default), enable | If enabled, only an address in the configured whitelist can connect. If disabled, connection to the access point is not limited to a specific range of devices. |
| Mode and Channel | Country code: two digit code Radio mode: 802.11a/b/g/n Bandwidth: HT20, HT40, HT20 HT40 Channel number: (number of channel options depends on selected radio mode) |
Once it is configured, County Code is a read only value. The Config Channel button invokes the Configure Mode and Channel dialog, which you can use to modify radio mode, bandwidth, and channel selections. |
