DoS Attacks - from varying sources and ports.
Hi There, Since all the working from home started - I've noticed sporadic interruptions while using Video conferencing and while gaming. I will get ping spikes for about 3-5 mins and then it's prett...
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
What IP addresses are shown in the logs with these attacks? Any of them 192.168.1.somehing or for external IP addresses?
Firmware is 2.5.1.8, says it's up to date.
Modem is a NG CM 1000.
as for the IPs they are all varying and I'm not positive how to determine if they're from an external address - of the 256 lines I pulled from the log, 125 of them are DoS related. An actual attack doesn't make sense to me, but if not this, what would be causing my newly minted spikes and disconnects while gaming?
