<p>I recently go a Linksys home wifi router, by default it enables
ipv6 on the LAN. If there is no native IPv6 on the WAN side (which
is my case since FiOS doesnt do v6 yet) the Linksys defaults to a
v6 tunnel.</p>
<p>For the first few weeks of using the router, I had no idea alot
of my traffic was going out via the v6 tunnel.</p>
<p>Then I started getting random reachability and availability
issues. Google would not load, but Bing and Yahoo would, and so
on. I thought it was a FiOS issue, but after digging, I discovered
the v6 tunnel, disabled it and all my issues went away. <br>
</p>
<p>I dont know what Linksys uses for the v6 tunnel because its
buried in the firmware, but any tunnel service is vulnerable to a
variety of issues that could effect access. Its odd that it always
effects Windows update all the time, but who knows.</p>

I’m on native IPv6 via Spectrum and have no problems with
Windows Updates. Could this be a tunneling issue?<br>

I can't imagine this to specifically be the issue, as all other
IPv6 traffic is fine, but at this point, I'm open to suggestion.<br>
