I'm using hAP ac2 as main router with an Audience to cover my house, due to current internet traffic IPv4 is really slow in my country so I decided to try IPv6, my ISP speed is 800mbps/200mbps, with IPv4 I have no problem to max out my ISP speed as 839mbps/220mbps with 10% CPU usage, but with IPv6 it dropped to 300mbps/200mbps with CPU 100% load, firewall is on. Then I replaced the main router to a cheap China YouHua WR1200JS (MT7621+128MB DDR2) which flashed to a custom firmware called Padavan, a customized Asus firmware same as Merlin, it gave me 839mbps/220mbps with IPv6.
I wonder when will MikroTik add the IPv6 offload? Since a cheap MT7621 can do, why not IPQ4019? Is there any restriction for this chipset?
Thanks
