NightHawk C7800 DoS Attacks
Having frequent DoS Attacks last couple months: SYNC FLOOD or UDP SCAN or ECHO CHAR GEN Netgear's brochure for this NightHawk C7800 says: SECURITY Denial-of-service (DoS) attack prevention...
Enable ddos protection if it has it. If not you can always block the ip. Also try unplugging the repeater jus t Incase it’s contributing to the issue. Next time it happens do a packet capture with wire shark and email it to your isp. They may put it on their blacklist for you. Let me know what you find out and good luck.
I did discover that "Disable Port Scan and DoS Protection" was disabled on my modem. (How, I haven't a clue). So I unchecked that box. Still having DoS Attacks, though. As far as blocking IP addresses, I wish Netgear provided a "Blacklist" feature, or other means to do it. So far, I haven't discovered a means via my Netgear C7800. I have checked on that "wire shark" for a packet capture and will keep that in mind for the future. Thanks!
