WCN36xx - denied association (code=104)

Hello,

I am using Linaro18_01 release, wifi chipset is WCN3660B (Dual band supported). I facing error while connecting the AP (TP-Link) with this specific router only.

I am able to connect with other 5G supported AP.

Can you please guide me here, what could be the issue?

Thanks,

In AP settings, I changed WiFi mode to 802.11a/n/ac mixed. Previously it was 802.11 ac only and WCN3660 not support the 802.11 ac. Its resolved the issue.
