I've been having lots of issues with loss of wifi over the last few months. Lots of T3 and T4 errors and having to reboot my router multiple times a day. Cable guys finally came out after the 2nd time and found the issue with a bad wire on the outside. They fixed it and we haven't had any events logged since or any major outages! Woohoo! The only issue now is that since i had been motitoring event logs and logs for a while now, I realized that i've been getting a lot of flood attacks. Most times I don't even notice them but a few times I could tell they happened because everything slowed down and a few devices lost connectivity (not all, is that normal?). I looked up the IP addresses and they come from all over the place. China, Czechia, Russia, Switzerland, Hong Kong, South Korea, Canada, and sometimes from the US - mostly universities?? University of Wisconsin, Univrsity of Southern California. After the attacks the logs show multiple [DHCP IP: (XXX.XXX.X.XX)] to MAC address (Is this our devices coming back online?) Is there anyway to stop these? Is it anything I should be worried about? Sometimes I also get Port Scans but they don't happen as often. Thanks for any suggestions.
