Issue with GEN3 Wi-Fi Module

Scope:

It has recently been noted that some GEN3 Wi-Fi modules were not working properly. After further investigation it was discovered that the antenna cable was plugged into the incorrect connector on the module. The module to still be recognized by the SMARTEN and visible from the Network User Interface page. However, this ultimately caused the Wi-Fi module to not be able to broadcast the controller’s SSID. Once the antenna was connected to the proper connector it function as expected.

Solution:

Remove antenna from incorrect connector and connect it to the correct connector. Refer to “Steps for Mitigation” for more details.

Materials Required:

Phillips screwdriver.

Steps for Mitigation:

1. Remove four screws that are securing module board to bracket.

1. Slide Wi-Fi module out from the bracket.

1. Carefully remove antenna from the incorrect connector and reconnect it to the correct connector.

1. Slide module back into bracket. Once module is back on the bracket, and the four screw holes are lined up verify that the extended part of the bracket is making contact with the connector. This will ensure a secure mechanical connection with the antenna cable and the connector.

1. Resecure the four screws.
