Solved Internet dropping out frequently (RT-AC87U)

[Anonymousx]

I have this issue too with RT-AC87U. The router reboots or crashes after a few hours. There is no reboot reason in the log.

Disabling the following AiProtection features solves it when Adaptive QoS is enabled..

Malicious Sites Blocking
Infected Device Prevention and Blocking

I am testing if traditional QoS or QoS disabled also solves it!

Only disabling the AiProtection features works with the regular Asus WRT software.

I switched to the latest Asus Wrt Merlin software and am testing if it is stable. So far no issues with all AiP settings on.
I will also test with an even older official Asus version.
