Yep IPv6 is borked in the alpha and beta builds. Getting the router to obtain a v6 address is a total pain in the butt it just don't work right.
Reverting back to older builds fixes the problem every time, I have tried many times. Always something with v6 just can't get it right. And yes I have factory reset the router cleared Nvram every install to no avail. Just don't have time anymore to keep playing the games. Asus 380.858 works best for me on my AC3100.
5300/Comcast here, and I agree with the notion that it's been dorked in builds since 58, but even with these latest builds, I (so far!) manage to finally get it working after wading thru a series of reboots.
After I recently updated/rebooted to 62 beta here, I then powered down the router, pulled the plug on my modem and let it all sit for a good 30+ minutes, then powered everything back up, did one more reboot on the router, and I got IPv6.
The nice thing is, once I get it, it "sticks" fine - I don't have issues with it randomly dropping out. I just dread having to power down or reboot the router these days!
