    Xfinity has completed work in our neighborhood, and it was quite confusing. They texted the work was completed; however, it was a disaster as everything was slow and my android tablet would not connect. After several calls without success to obtain a live agent, I was able to have diagnostics run, and everything is working fine. The resolution was the system is “catching up” and it will take several hours. At first, I only had IPv6 and not IPv4 and could not reach certain websites. Then miraculously things caught up. I rebooted the router again and everything seemed intact. I reset the tablet and was able to use it.

    Several hours later, IPv6 dropped out. I have had this before when they were doing maintenance and my thought is to let it settle. They are in the area again tomorrow to do another section of our development, and I don’t want to go through the same thing again.

    I know the IPv6 will come back, but here is my QUESTION: Do I really need it? I am a home user with just a laptop and tablet without devices on a network.

     

    THOUGHTS?

      Just FYI, if you have a router and devices connecting by WiFi, that is a network.

      But no, you do not need IPV6 if you connect to websites with IPV4 and it is still available on your ISP. IPV4 is still the Internet protocol most frequently used.

      Along the lines of what @PKCano said above, if there’s a way within your router to completely disable its use of IPv6, go ahead and do just that, rebooting it afterwards so that it will get an IPv4 address from Comcast’s equipment.

      Then, say, a couple of months after Comcast has finished your entire neighborhood, go back into the router and re-enable its use of IPv6 and hopefully you won’t have any further issues due to their ongoing upgrade(s) in your immediate area!

      Do I really need (IPV6)

      It depends where it’s used.
      Internally – in your home – it’s used by Windows for peer to peer networking.
      Externally – the internet – it may be used by some sites where they are short of IP addresses, or on your router where your ISP is short of addresses. Your ISP will manage this for you.

      I tend to leave the router alone so that I am not fighting the ISP or Windows.

      cheers, Paul

      Thanks all,

      I have IPV4 and IPV6 dropped out while the network was catching up. They ran all diagnostics and nothing was wrong with the router which they classify as a gateway. Right now IPV6 says no network/internet in windows 10. As Bob99 suggested I will wait a day or so because xfinity rebooted several times today and when they sent the text that the work was completed they did not explain it takes a few hours to catch up as was explained to me after the fact. As long as it is not in dire need for IPV6 to use my internet I will continue to monitor for my home consumer laptop. After several hours I received a second text saying all work was finally complete which meant caught up and changes took place.

      How do you know V6 dropped out?
      What did it affect?

      cheers, Paul

        Hi Paul,

        I check the network and sharing center then active networks, and details.

        Since the ISP upgraded the network, I wanted to make sure that all services were still there.

        Initially both IPV4 and IPV6 both had Internet connectivity under WIFI status, and later in the evening, IPV6 then stated No Network Access.

        In the past I would reboot the router when this occurred if I notice it, and it would come back because Xfinity has a habit of doing that when the router renews its lease from time to time. I check everything all the time and probably don’t need to. 🙂

        It didn’t affect anything; I was checking to see if it was there.

      You can also turn off IPV6 in the NIC and leave the router alone with both IPV4 and IPV6 available.

        PKCano,

        I was thinking to do that and, in that manner, won’t worry about it or check on it from time to time. Do you think it’s the router or the NIC? I really think it is the service in the area. One other way for me to check is to use the ethernet cable.

        Thanks!

          By turning off IPV6 in the NIC, you don’t have to worry about it.
          This my Ethernet adaptor, but you can do it for whatever you are using.
          Right click on the adaptor, choose Properties, uncheck the IPV6 protocol (don’t uninstall) leaving IPV4 checked.
          Then it will only use IPV4.

            PKCano,

            Thank you I will do as you described and not worry about it any longer.

            I’ve read several articles that it might be a faulty driver in Windows 10 device manager.

            Also quoted from the article are as follows:

            To resolve this error smoothly, you need to find the possible causes of it. There are three common factors that may trigger the IPv6 no connectivity problem.

            • Outdated Networking Drivers: If your networking drivers are outdated or faulty, you should replace them with the latest version to resolve the error.
            • Firewall and Antivirus Programs: Sometimes your antivirus programs will prevent the IPv6 from working properly. For this situation, you can disable them temporarily and check if your problem is resolved.
            • Incorrect HT Mode: Incorrect HT mode settings can also trigger the “IPv6 connectivity no network access” problem.

      I usually run ItSamples.com’s Network Activity Indicator tool to check my WLAN & Ethernet adapters connections with both IPv4 (TCP/IP v4) & IPv6 (latest version works great with Win10 & Win11)

      edit: I have this valuable app installed & always loaded at startup, so there’s a network tray icon in the lower-right hand corner that animates; something that was there in the XP/Vista era.
