recently started noticing lag spikes, bad ping, unstable connection, etc. I logged into my modem (192.168.100.1), and noticed thousands of uncorrectable errors. picture here: https://i.gyazo.com/7c38a9ca71cc046e12906f28f16a4f68.png i did recently switch to gigabit ethernet with comcast. i had to upgrade my modem, which is why I got the CM1200, since my older modem couldn't handle those speeds. A tech did come a few days before I switch to gigabit, and he swapped some fittings on the wall and outside. so it's possible he made it worse.

So I recently just setup ipv6 on my router, but the speeds seem to be lacking compared to ipv4. I'll give some details below of my equipment and service. Modem: Netgear CM1200 Router: Netgear Nighthawk R7000P ISP: Comcast - Gigabit When on ipv6, my xfinity speedtest hits around 657 Mbps. But if I turn off ipv6 (within my windows network adapter), my ipv4 speeds hit around 945 Mbps. I will post more information down below. Speed test I used: https://speedtest.xfinity.com/ I got 10/10 on this site: https://test-ipv6.com/ And here are some screenshots of my results, as well as my ipv6 setup within my router. ipv6 speed test: https://i.gyazo.com/82f846cbcc8881e73d398a61bf7dfc96.png ipv4 speed test: https://i.gyazo.com/fe07194cae6aaa8b7a98c0f74baf2053.png ipv6 connectivity test: https://i.gyazo.com/73c79d5a4bed8943ca9314e66a09ee6a.png Router ipv6 settings: https://i.gyazo.com/c2588e46aa45f28e4e1d239f95b862d3.png For my router, I intially had chosen Auto-detect, in which it choose DHCP for me. As you can see, I also changed my DNS to cloudflares 22.214.171.124. Thanks for any help on this issue.
