For one primary PLC communicating to many coworking PLCs, it is strongly recommended to use an industrial AP router as the access point for all SE-130WA converters.

Prepare an AP router and turn it on, so the AP router's SSID can be detected by all SE-130WA converters.

For SE-130WA connecting to primary PLC:
Set as Server mode.
Set SSID as AP router's SSID.
Set Network type as "Infra".

For all SE-130WA connecting to coworking PLC:
Set as Client mode.
Set SSID as AP router's SSID.
Set Network type as "Infra".
Set Destination IP as the wireless IP of the SE-130WA connecting to primary PLC.
