    RT-AX58U not forwarding IPv6 RA in AP Mode

With any other WiFi APs (e.g. Linksys, Ubiquiti, Devolo) connected to the...

    IPv6 DNS

    Hello! Router is RT-AX88U with 386.3_2 firmware. Clients are getting ISP IPv6 DNS instead of Google IPv6 DNS (DoT), manually set. System Log > IPv6 shows the expected Google DNS, 2001:4860:4860::8888 2001:4860:4860::8844. Is this the expected behaviour or we are doing something wrong?

    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...

    RT-AC68U IPv6 settings if ISP does not provide IPv6 at all

    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?
