June 2022 we noticed a lot of issues with our internet dropping
Nighthawk CAX80
Firmware Version V2.1.4.2
Purchased 09/17/21
Sometime early spring - June 2022 we noticed a lot of issues with our internet dropping, modem would just drop all together, but with the recent ISP merge we chalked it up to that. However the merge is well done now, and after today's incident of reboots every 5 -10 minutes and a conversation with the ISP, looked at the logs, found this thread, we concluded my device is experiencing false DoS severing connection, from everyday sources like facebook and the ISP.
We performed this devices first factory reset since purchase. It seems to be working for now, still on 2.1.4.2.
Our modem worked fine, the first few months we had it, again it started having more and more drops sometime early spring/mid summer, around the same time 2.1.3.7 released?
I would hate to disable DoS protection. The release notes for 2.1.4.2 are not reassuring this was taken care of either. Whats going on? I need this device to be reliable for work.
Edit: I see someone shared another thread, will take a look here as well.

Please post a copy and paste of the modems connection status and event log page.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.
