HELP/ADVICE De-bugging Attacks on Nighthawk AC1900 (Showing Logs)

Hi -

 

I have unusual bandwidth activity on my Comcast account (over 1TB this month when normal monthly usage is 300GB) and so I have been spending hours trying to both troubleshoot devices as well as the Nighthawk. I have confirmed that all of the 'Disable' security features (DOS protoection, respond to pings, etc.) are UNCHECKED - which as I understand it is the recommendaiton. Yet still I continue to get apparently attacked in a series of ways.

 

See image attached for sample logs. 

 

This is a Model Number C7000v2 and Firmware Version V1.03.01

 

Does anyone have any advice or tips on how to troubleshoot this? Thank you very much!!

    "DOS protoection, respond to pings, etc.) are UNCHECKED" When you say unchecked, Does this mean there disabled in the UI or enabled? Recommended to enabled these security features. 

     

    Contact your ISP and have them change your WAN IP address. 

    Turn OFF ALL devices on your LAN side for say before going to bed. Look at your data used before. Then look again the next morning to see if you notice anything. Hopefully rule out any LAN side device using bandwdith.

      Thanks FURRYe38 for your reply. What I meant is that in my Netgear Genie UI the "Disable" radio button is unchecked, which I assume means (with the double negative) that it is in fact, enabled? (image attached)

       

      Thanks for your other suggestions. I will try that.
