# [From QnA] I can't configure WIZ145SR: Invalid Msg Recv

## Question

Asked by jameskim on 2013-09-09 in Serial-to-Ethernet & ConfigTool.

I’m trying to configure a new WIZ145SR module using the WIZ14xSR ConfigTool Rev 1.41, but each time I click the search button
the debug port on the module shows: Invalid Msg Recv.
The ConfigTool does not find the device. How can I configure it!!
Here is the log from the debug port:

[quote]Boot Ver1.3

I click the Search button three times and each time the Invalid Msg Recv is sent out the debug port.

Hi,

In case of having multiple IP address in your computer, you can get “Invalid Msg Recv” when searching WIZ140SR.

First, [color=#FF0000]eliminate other IP addresses except one IP address [/color]from your computer.
Then, Click “Search” on your WIZ140SR configuration tool.

I think you can get a board information on the Configuration tool without “Invalid Msg Recv”.

Thank you.
