I recently notice this problem after I have 500Mbps package speed

before never happen cos my internet was only 300Mbps+
Im using mikrotik hap ac2

I realized when I do p2p or Steam download with ipv6 enabled,  mikrotik cpu usage only 1 core at 100%

then im getting unstable connection via Ethernet ports

and the worst case is my ethernet port on mikrotik will stop working during heavy download on torrent client for few minutes, then I have to "disable" "re-enable" manually to fix my ethernet port

if disabled ipv6, then all works totally fine

is there any solution ?
Watch this video to reproduce the problem


is it just my hap ac2 ?

or does ur mikrotik device also like this?

I'm currently running the latest stable version routeros 7.12.1
