[DoS attack: ACK Scan] from source... Need help

Hey all,

 

This issue has been annoying me for almost a month now. It seems to show up in the logs differently depending on the settings. Right now, with almost factory settings it is showing up in the log as,

 

(This is just a sampling, there are many more sources)

[DoS attack: ACK Scan] from source 184.25.146.65,port 443 Thursday, Jun 20,2019 19:45:44
[DoS attack: ACK Scan] from source 104.77.9.242,port 443 Thursday, Jun 20,2019 19:44:08

If I disable Port Scan and DoS Protenction it shows up as:

[UPnP set eventPublic_UPNP_C3] from source xxx.xxx.x.x

 

These "attacks" happen about every 10 minutes on every device on my network, causing bad lag spikes especially when gaming.

I have tried many different potential solutions online but almost all forum posts I have browsed are pretty outdated.

My Playstation is running on ethernet connection and still has this issue. 

We thought it was our outdated ASUS router, so we upgraded to this nighthawk (much better performance otherwise) and still have the issue.

I thought it could be some sort of malware on PC, but the spikes still happen with my pc completely off. 

 

As the only person in my house who somewhat understands this stuff it would be nice to find a solution and put and end to the complaining from my family Smiley Very Happy. Thanks!

Hey,

 

I'd love to help, but unfortunately you're in the wrong section of the forum for your model of router, you'll need to post here:
