I have an Archer AX21 v2.0 that did work correctly with IPV6 before I updated to the latest firmware but since updating to the 2.1.8 Build 20230426 rel.32867(5553) firmware build IPV6 no longer works. It worked before applying this firmware update and I have confirmed it isn't an ISP issue by testing a different router which had no issue with IPV6. I felt I had to update due to the secuirty issue mentioned here https://community.tp-link.com/us/home/forum/topic/607966

Is there any way to fix IPV6 on this current build of the firmware or am I screwed until a new version is released?

Thanks for the help!
