Slow Speed According to the Test

Well, it worked! Got my new NetGear AC1750 router set up and my speed is finally up to where it should be! Ping time is much lower too.

Well, I ran the IPv6 test and it failed just like before, saying no IPv6 address detected. But then it says at the bottom my DNS server (from the provider, Xfinity) appears to have IPv6 access. In the properties tab, both v4 and v6 are selected and obtain DNS automatically. But if Xfinity has access why would I need to switch to "use the following address" and type in a non-xfinity address from the list?

I had to select auto config under setup and now here is a new screenshot of the ipv6 test page where it shows I have both:


I went to the connectivity test link and it shows native.

Native ipv6 is good

Good to see you've got your IPv6 working

Have you tried the DNS Benchmark app with your new router?

This site addresses some of the concerns with using an ISP's default DNS.

Why You Shouldn’t Use Your ISP’s Default DNS Server

I didn't know about DNS over HTTPS (DoH)!I'll explore that later.
thx
