    Which SDK are you using? Which kernel? Have you modified the DTS? I need more information on what the software system is that you are using.

    Great, thank you. May I ask how you were able to create this issue? Or did it seemingly happen randomly? Could you provide wireless sniffer logs or wl18xx logs?

    Regardless, the driver is able to reset the WL18 and then immediately associate and establish the link.
