@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 v18.104.22.168 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.
I'm connecting to Masso without issue, but file transfers are dodgy at best.
Sometimes a file will transfer over & actually work .. Sometimes the progress bar is moving but then I get a 'no response' message part way through the transfer .. and some files have gone through but cause the Masso to freeze up when I try to open them. (all of above mentioned files were created with same postprocessor)
Just noticed my WiFi module is also showing v1.2.0 so I'll be looking for the above mentioned update as well.
I have WIFI in my shop and don't have any problem with anything else connecting. I purchased new WIFI card and installed new software and still can't connect with my router 3' away from controller. I give up.
