The attached figure is WIZ110SR, not WIZ750SR-110.
If you use the product of attached figure, you have to use another configuration tool, which is different from WIZ750SR-110.

But if you use the WIZ750SR-110, please refer to the troubleshooting guide provided by @rena .
I apologize for the confusion regarding the model number. I was provided the wrong information for the card when it was delivered to me. Now I realize I had the wrong config tool. I was able to connect once I installed the correct tool provided by irina_kim. Thank you irina_kim
