according to this document:

it needs to do “wifi client setsecurityproto”.  
Have you tried this command first and see if it can connect wifi client?

If it needs this command, I believe you also need to set  
config set dataConnectionService:/wifi/secProtocol 3

For the definition of enum, you can see here:
