Orbi 20 DoS Drops Internet
Howdy! So, I was given an Orbi 20 router and tried to use it to replace my ancient networking setup. It worked fine for about a day but now about once or twice an hour it's been dropping internet (b...
Well I fixed the problem but i'm not really sure how. All I did was toggle logging of DoS attacks first "off", then "on". Then, I cleared the log. Now the issue is resolved and it no longer reboots. After looking through these forums, had I known upgrading firmware causes such grief, I never would have done that step when I first set this up. Anyway, I'll stay away from future firmware updates for now. Thanks all!
Hi so I'm using an Arris SB6183 Cable modem. It's about a year old. I do use a switch but it's after the router. Nothing in between modem and router. When it drops connection the top lights blink which I assume means its cycling power. I have noted that everytime it has done this, in the logs it shows "DoS attack: ACK Scan" which coinsides with the service interuption. I don't experiance this when i switch my old router back. I wasn't having network issues before, I just wanted to use this Orbi because my old router is only 10/100. Right now I'm using it with DoS logging disabled to see if that makes a difference.

Good to hear
You can select the log items that you feel you want the RBR to collect. You don't have to have them all set to logging. I don't.
Please mark your thread as solved so others will know.
Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
