NetGear WNDR3700
Reset: No
Errors: No
Status: Everything appears ok, but IPv6 errors
upgraded from 29974 - 2016/06/20
when I went to http://test-ipv6.com/
I get the following errors (ipv6 was fine before):
Your Internet Service Provider (ISP) appears to be ROADRUNNER-WEST - Time Warner Cable Internet LLC, US
Our tests show that you may have MTU problems with IPv6; this can cause web sites to load slow (or not at all) when web sites enable IPv6. [more info]
Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access.
Danger! IPv6 sorta works - however, large packets appear to fail, giving the appearance of a broken website. If a publisher publishes to IPv6, you will believe their web site to be broken. Ask your ISP about MTU issues; possibly with your tunnel. Check your firewall to make sure that ICMPv6 messages are allowed (in particular, Type 2 or Packet Too Big). [more info]

Do you use RADVD? There was recently RADVD update...
you can set MTU in custom config...
I use DNSMasq and have RADVD disabled.
I went back to build 29739 and it is still there.
So it could be something in the way I configured it, or the test has changed to pick up something I didn't see before. The Test Page says the error could be related to the firewall blocking ICMPv6, type 2 (Packet Too Big).
I have never done anything to the firewall settings.

Today I went to build 29974 (06/20/16)again.
At first it had the same problems, but now it works fine?
