I joined this forum for help with my TL-R470+, I cannot figure out what is wrong

On my Logs I am seeing many " Detected stationary source udp flood attack, dropped 15 packets"  for example.  I have lowered the threshold of the Flood defense for UDP in the Firewall settings trying to limit this outgoing behavior  I was being blacklisted and blocked at certain websites because of this activity.  I have scanned all computers connected to the router and none have any malware or viruses.   Even trying to connect a VOIP phone adapter it triggered this response in the logs.   No way does that phone adapter box have a virus!  But everything connected to the router is claiming a UDP Flood attack in the logs.

My question is.. How do I correct this problem?  I'm beginning to think there's something faulty about my router, it has not done this in all the time I've had it.

I have even re-loaded the firmware, which was the latest for V4.0
