WiFi Client
NOTE: JACE-8000 units deployed in the U.S. (and in countries that accept U.S. certification) and configured for Client mode cannot connect to an access point that uses Dynamic Frequency Selection (DFS) channels in the 5 GHz range. Unsupported DFS channels are listed here: 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140.

All traffic not on the local subnet is routed through the default gateway on the JACE. This includes any broadcast traffic (Discovery) from the JACE. This means that if gateway switching is "enabled" on the JACE AND the Access Point provides a new default route in its configuration response to the JACE, then all non-local network traffic and broadcasts are routed to the Access Point and not to the field bus Ethernet when the JACE is attached to the WiFi network. It also means that the supervisor should be able to "discover and learn" the JACE.
Conversely, if switching is disabled, the default gateway will stay pointing at the default gateway in the TCP/IP configuration of the JACE, regardless of any default route provided by the Access Point. This means that the supervisor/
NOTE: Although discovery (broadcast) will not work, you can still add devices manually.
- The JACE can communicate with field bus devices.
- Other devices on the IT network cannot connect directly to the field bus devices, since they are on a separate network.
