QUdpSocket not receiving packets over wifi

Question

I am using QUdpSocket to receive UDP packets over WiFi. My program was running fine until my system crashed. After that I am not able to receive UDP packets. I used Wireshark to ensure that packets are arriving on my system but my slot readData is not getting called. However I can receive packets when I send packets on localhost using QUdpSocket.

Answer 1

I still dont know why it happned but fixing my firewall with microsoft fix it tool and using system restore solved my problem. =)
