Hello,

''I encounted an issue when tried to connect with complicated wifi network recently.''  Which application you are working on? One of the ways of initial authentication process carry out using a preshared key. That is the prerequisite of successful handshaking. 

Did you select the correct WPA key?

Thanks.

Hi Kazi,

I am using wifi shell application running on nrf7002dk similar platform. The "wifi connect" command woks on most of the simple network (family use router/AP). However, when our equipment deploied in complecate network enviroment like library, shopping mall, hospital etc. sometimes it can't connect to the network correctly. equipment output the error info as "WPA: 4-Way Handshake failed - pre-shared key may be incorrect".
