In order for Fiddler to be able to capture network traffic, the origin device/application must have their proxy settings pointing to the Fiddler application proxy, which by default is running on port 8888 for Fiddler Classic. Furthermore, Fiddler only captures HTTP TCP traffic or protocols like Websocket that run on top of the HTTP TCP connection. It seems you are trying to capture broadcast packets, which are probably UDP and not TCP. If this is the case, then Fiddler will not be able to capture these packets. You will need a lower level networking tool like Wireshark.
