    AC66U slow with 6in4 - advise on new router

    I've been struggling with my AC66U (old rev.) speed issues, finally I narrowed it down to IPv6. When I enable 6in4, my speed over ipv4 gets capped at around ~130-150 mbps, and router is lagging like crazy (ICMP 20-30ms, unresponsive web), as soon as I disable IPv6, I get ~700-900 mbps without...

    Hello all Maybe my question is stupid, i apologize if so, but somehow i feel that answer is not that obvious. My ISP does not provide IPv6 at all. Should i keep IPv6 on my router disabled or i should enable it anyway? If i should enable it, then which connection type should i pick?

    Dual Stack (IPv6): DNS for IPv6 is not my AC88U

    Hi, I figured out that in my dual-stack environment my Clients get for IPv4 my router's DNS IP but for IPv6 my Client's get the Providers DNS. My expectation would be to also get the router's IPv6 (the local one) for DNS. :/ I Use DHCP-PD and it works so far. Also I set up DoT on WAN settings...

    Router IPv6 hosts entries

    I noticed today after enabling IPv6 and testing nextdns.io, that I was seeing AAAA requests for router.asus.com in the nextdns.io console logs. Sure enough, the hosts file has no IPv6 address for router.asus.com, so it was apparently forwarding the AAAA requests upstream with no luck. After...

I’ve just done a factory reset of my AC68U, and set it to use a native IPv6 WAN connection, and stateful LAN. However my device...
