Hi,

Based on the following thread, I'm using the mentioned beta firmware in order to access the network using IPv6 addresses.
https://community.tp-link.com/en/home/forum/topic/520274
Every time I reboot the router, I get IPv6 addresses for all connected devices, however, after about 25 minutes, all devices lose their address (just the IPv6), making it unable to make any request to the desired server. IPv4 works fine after that period.

On the advanced status tab, the "Internet" section and the "LAN" section shows only an empty field instead of the IPv6 address. After rebooting the router, the addresses appear again.
I'm using two devices and they produce the same issue almost at the same time.
Has anyone encountered a similar problem?
Could this be an issue with the settings, or could this be more ISP related issue? According to the ISP, everything is correct.
Thank you all for your help in advance!
