Connecting of device

Thank you.

Hi @bumbafidele, welcome to the Cayenne Community.

Which connectivity sketch are you attempting to use with this shield? The ‘HR911105A’ refers to the model number of the socket, which doesn’t matter, but you do need to have the correct sketch for your shield.

The square black chip in the center should show the shield’s model number so you can make sure you’re selecting the correct sketch:

Thank you for your answer,

until now. In attachment the response of my serial monitor. Please I need
help.

That “DHCP Failed!” message means that your Arduino is unable to receive an IP address from the router on your network. I made up a big post of reasons that we’ve run into where users have seen this error some time ago. I’d start there and step through each of these issues to rule them out or see if they help.
