I'm really stumped as to how ipv6 could partially fail like this only

completely fail.
Anyone have any idea what might be happening here and/or how to fix?
Hi David,
If ping works, but bigger packet things don't, then you might have some
PMTU
issue that is only affecting IPv6. You can confirm this with a tcpdump
trace
quite easily. Look at the packet sizes. Both things you've mentioned
(opening a
web page and updating antivirus) are http, and it does usually use the
maximum
transmission unit.

Makes some sense. I'll take a look on my router and see if perhaps I'm
inadvertently blocking some ICMP packets.
That said, one thing doesn't quite seem to fit with this explanation:
Why would "curl -6 ipv6.google.com" while "w3m -6 -dump ipv6.google.com"
fails?
Thanks,
DR
