I just bought an RT-AX88U and flashed it with 384.15_0 firmware, but today I find an issue with the firmware. If I change the IPv6 setting to Native and click on apply button, it will work and I can get IPv6 addresses on both the router and my laptop, but the setting will change back to None when I reboot the router. Earlier today when I enable IPv6 before configuring other settings I can't even save jffs and SSH settings, then I reset the router and configure all other settings before setting IPv6, now other settings won't disappear after rebooting but IPv6 still have the issue. My previous RT-AC68U works just fine with exact same settings, I'm not sure if it's a bug or not.

I have uploaded my cfg file, please remove the .txt postfix and unzip it. Thanks in advance.

And you configured it manually after that (i.e. you didn't reload a previous backup file)?
 
What settings are you changing past defaults after doing a full reset including checking the 'Initialize all settings...' checkbox?

Click to expand...
1. WAN connection details
2. Wireless details, separate 2.4GHz and 5GHz
3. LAN setting, change IP address to 10.0.0.1
4. DDNS setting, enable an oray DDNS client
5. Enable "Format JFFS partition at next boot" and "Enable JFFS custom scripts and configs", change USB mode to USB2.0, change NTP to cn.pool.ntp.org, enable SSH for LAN, enable web access from WAN
 
@redraiderj, Alert! Disable web access from WAN immediately. This is a high-security risk.

Here are the different lines:

Code: 
ipv6_get_dns=240e:58:c000:1000:116:228:111:118 240e:58:c000:1600:180:168:255:18

ipv6_prefix_length_s=
ipv6_rtr_addr=240e:e0:591d:a600::1
ipv6_service=dhcp6
ipv6_wan_addr=

I notice some of them will change after I reboot the device and enable Native option again, so I don't think there is a way I can update those values with scripts since they are not fixed values.

Look for clues in the router's syslog during the boot process for reasons why it isn't starting the IPv6 interface.

I just rebooted my router, and save the logs as Startup.txt attached, then enable IPv6 and save the logs as EnableIPv6.txt. Then I search for ipv6 in each of them, and here are the results:

Looks like I can't upload files due to Cloudfare's restrictions, here are the links to them.
