# [WIZ750SR] I can not module searching with the configuration tool.

## Question

Asked by WIZnet on 2018-02-21 in General.

- The symptom of not searching in Configuration tool is as follows.
  1. Set the virtual machine(virtual box) to disabled.
    - Control Panel - Network and Sharing Center - You can see the list of networks connected to your PC when you change the adapter settings. From there, set all of your virtual machines to “Disable”.
    - And search again with the configuration tool.
  2. Disable Wi-Fi on your PC.
    - Go to Control Panel - Network and Sharing Center - Change the adapter settings and set Wi-Fi to “Disable”.
    - And search again with the configuration tool.

- It doesn’t solve search, the workaround is to check the following:
  1. Make sure that the LAN cable is working properly.
    - Check that the LAN cable is defective.
  2. If there is no problem with the LAN cable, connect the product directly to the PC 1:1 and search with the configuration tool.
    - If it is search, check the connected network structure.
    - When testing in a corporate network area, If can block the search IP / Port of the configuration tool in the corporate network system. Please check this part. The configuration tool uses ports 50001 and 50002.
    - If not, check the switch (router).
    - Please check if the router is working.
    - There is a possibility that the LAN port of the router is broken. Please replace it with another router.
