RAX20 router loses IPV6 connectivity several times daily

Thanks for your reply.

I haven't connected a single pc to test, because I can't keep only that pc active for any significant time without access to the rest of my home network. I would imagine it would workf for some part of a day, but I can get IPV6 to work on the entire network for a few hours now - then it shuts off.

I haven't called Xfinity because their tech support on real networking issues is so poor and so long as they see IPV6 active - they won't see it as their problem. As I can get IPV6 to work for awhile, the problem seems to be restricted to the router.

I have lost IPV6 almost every day. but it's gotten worse lately.

I have unplugged both modem and router for 15 minutes, then powered the moden, then router back on. To no positive effect.

I'm on the latest firmware 1.04.100. Perhaps that's what's made it worse? I would prefer not to go back to a prior version - that would be giving up on updates unless the update specifically says it's addressing the IPV6 issue.

I've done a google search and see quite a number of Netgear/IPV6 issues being discussed - should I just look for a different router that has better IPV6 stability?
