IPv6 working on PC but not phone or tablet

[Dan15]

Hi,

I'm having trouble getting IPv6 working on some devices. It's working on my computer with no issues (I get a score of 10/10 on https://test-ipv6.com/), however my phone and tablet are not acquiring IPv6 addresses.

I am using Comcast Xfinity which has native IPv6 (/64 range per customer). Under Advanced → IPv6, Internet Connection Type is set to DHCP, and IP address assignment is set to "Use DHCP Server". "Router's IPv6 Address On WAN" and "Router's IPv6 Address On LAN" both display valid IPv6 addresses in Comcast's IP range (AS7922).

Nighthawk RAX45 (AX4300)
Firmware: V1.0.2.66_2.0.42
Laptop (IPv6 working): Lenovo X1 Extreme, 1st gen, running Windows 10 version 2004
Phone (IPv6 NOT working): Samsung Galaxy S10
Tablet (IPv6 NOT working): Samsung Galaxy Tab S7+

Any ideas?

Android does not support DHCPv6, only SLAAC (auto config). If you want IPv6 on your Android devices, use Auto Config (SLAAC)

Perfect, thank you! I changed it to SLAAC and now everything is working fine. I think I originally changed it to DHCPv6 because I was having issues with IPv6 on my laptop, but it seems fine now.
