DDOS Attacks causing disconnecting internet connection
My internet connection keeps on disconnecting and after going through the logs, there are DDOS attacks that is causing this. I had contacted my ISP to get new IP, that didn't work. I got the latest O...
These were false positive attacks. I did all that was suggested, including
isable backhauk daisy chaining, MIMO and Fast Roaming, shutting down the two satellites and just leaving the router. I thought it was my switch and router, but replacing those didn't do anything. We were not doing anything different, the disconnects on the router just happened. I woke up in the middle of the night and the disconnects were happening. I found an old ASUS router and hooked it up. It's been up for 3 days now. After googling and doing research online, this seems to be a common issue, and Netgear has not come up with any robust solution. I returned the Orbi and just stick with my ASUS that has been reliable for me now and in the past.
Problem may be in the response of the router to ping requests. Go to Advanced>WAN Settings and be sure the “Respond to Ping requests” is unchecked (disabled). If the router actually needs to respond to Ping (or ACK, SYN, or other DoS attacks), it will bury itself and you will get the magenta ring.
Unfortunately, if you are using OpenVPN through the firmware, enabling OpenVPN will automatically enable (check the box) for Respond to Ping requests. You cannot have one without the other. This is a major bug in the firmware. Netgear has known of this for 2 years, and there is no solution on the horizon.

I overcame this limitation (enabling VPN will automatically enable Respond to Ping) by doing the following telnet command (this does not impact VPN, it will continue working and the router will stop responding to pings):
root@RBR50:/# config get wan_endis_rspToPing
You will get the default which is 1 (means Orbi should respond to WAN ping requests)
root@RBR50:/# config set wan_endis_rspToPing=0
root@RBR50:/# config commit
