@grg_p yes as
@testyourdesign mentioned that the first best way is to get an automatic IP from the router. From the image that you shared, the IP can't be 0.0.0.0 as its an invalid IP anyways. You can try something like 192.168.1.100 for example.
So when fixed IP in not checked, and you click connect, what message do you see on the screen, it might take upto a minute for a message to be displayed if the connection can't be made.
Actually I just saw that your wifi module is running software v1.2.0.0 and it has some known issues, we will be releasing an update to fix this in the coming week as this version is known to cause issues.
