ESP-13 wifi shield from Jaycar - how do you get the damn things to work????

Hi

I'm using one of those ESP-13 Arduino shields as part of a robot car kit I bought from Osoyoo.
The board is designed by the Doit company of China. It has a notorious 2 pole DIP switch without much information about what exactly the switches do.

I got the kit to work, including their example 5, wifi function , broadcast SSID, web-page for configuration, etc. The kit uses an Arduino Uno board with the ESP-13 wifi shield.

I also got the very useful example posted at

to work, first time - I highly recommend those instructions.

But...none of the simple standard wifi example scripts supplied as part of the Arduino IDE run on this ESP-13 module.
For example, the simple scannetworks script just returns "wifi module not present" in the serial monitor.

Can anyone tell me how to get scannetworks working on my ESP-13 + Arduino kit ?

Many thanks
