# WIZnet S2E Configuration Tool V1.1.0 Not finding device

## Question

Asked by karen on 2020-01-15 in Serial-to-Ethernet & ConfigTool.

WIZnet S2E Configuration Tool is not able to find my device.

I can ping it and I can also open a TCP/Ip connection to it but I can’t configure it.

Not sure what more information may be useful here. Let me know.

my device is a WIZ750SR-110 though the chipset is different than what is shown on the product page.

Is your PC connected to the same network as the WIZ750SR-110?
Please change the search method to TCP unicast.

Hello, [@karen](https://maker.wiznet.io/u/karen).
There are several reasons why the config tool does not find devices.

- Firewall issues

- If using multiple network adapters

- Other cases

Please refer to the below link.

[@karen](https://maker.wiznet.io/u/karen)
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.
Link : [WIZ110SR Configuration Tool](https://www.wiznet.io/wp-content/uploads/wiznethome/S2E%20Module/WIZ100-105-110SR/Utility/WIZ1xxSR_Config.zip)
But if you use the WIZ750SR-110, please refer to the troubleshooting guide provided by [@rena](https://maker.wiznet.io/u/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
