After a few days my IPv6 stopped working but only on LAN network (WAN ok fine), even with factory settings this happens, Sometimes IPv6 works for 7 days, sometimes for 2 days before failing ...
I have valid IPv4 / ipv6 addresses.

Does the ISP change your prefix?

Update: I just noticed that IPv6 stopped working and that "Lease time remaining" now shows "Expired"
Where are you seeing that message?
How is your ISP providing you your IPv6 prefix? DHCPv6-PD?
How have you configured it?
I was experiencing the same problem on the LAN side, but I haven't had any issues since I changed IPv6 to 64.
