Windows 10: What does "no IPv6 connectivity mean? How do I fix it? Solved

    What does "no IPv6 connectivity mean? How do I fix it?

    I'm traveling, thus subject to public Wifi. Several times I go to the web, and get an error message. "You are not connected to the internet". However, the Wifi icon on the task bar shows that I am on the SSID with internet access.

    I checked the status of my Wifi Adapter and it shows what is in the attached screen shot. It says I have IPv4 internet, and shows IPv6 no internet.

    How do I fix this? The internet adapter is a Realtek RTL8187 Wireless 802.11b/g 54mbps USB 2.0Click image for larger version.

    You don't, it's not needed (or used) for internet access at present. About the only thing that uses IPv6 at present is a Windows Homegroup (if you have set one up).

    IPv6 is there for future use, see this guide...

    Why am I getting the error message, "Mozilla Firefox could not find the website, Windows 10 Forums. There is no internet connection"?

    Apparently in about June 2012, ipv6 'went live'
    Rehearsals over, IPv6 goes prime time June 6 | Network World

    Any devices not capable of handling the later protocol are, of course, restricted to ipV4.

    Thus your device may have ipv6 available, but the one you're talking to may not. However, it would probably have to be significantly old for that to be so.
    Most of the PCs, IP-enabled devices, and network hardware sold over the past few years has included IPv6 technology--at least as an option. Unless you’re still using hardware and software from 5 years ago or more
    (June 2012).

    The change will eventually mean swapping the home routers of millions of customers as older devices cannot work with the new system.

    So, the public Wifi source has an old router? Yes? Or is it my adapter?

    Most (if not all) routers,Lan and WiFi cards made in the last 10 or 15 years are capable of using IPv6 and in fact Windows uses IPv6 on the local network for some of it's services , What you are seeing is that the ISP has not enabled IPv6.

    Eventually ISP's will enable IPv6 but to do this they must spend a lot of money to replace their antique equipment, Doing that will not happen anytime soon ISP's would rather stick money in their pocket instead of adding to the quality of your internet connection.

    If and when an ISP enables IPv6 you will not have to do anything it should just work. Unless you followed some misguided uninformed person on a help forum who told you to disable IPv6 to fix something which in the end only needed you start,stop or reset your lan or wifi card.

    You would probably be surprised to see what country is the leader in IPv6 support

    Your wireless adapter is a museum price top speed 54 meg new AC type can run at 3gig. It's not just the speed g type is very old and a lot of routers don't support it any more as most are n type 300 meg or above being old it will not understand modern encryption types. A new adapter is very cheap from £10

    Your device will (should) be able to handle one or the other, and will choose accordingly, since IPV6 is "live" devices that can handle the standard will default to using IPV6 where the other devices will use IPV4, so it should seamlessly just "work" if your experiencing issues with "no connectivity" at times, you can disable IPV6 (or uninstall the protocol which I DO NOT recommend doing) if you wish, just keep in mind you will be limited to IPV4, however at this time (time of this post) IPV6 is not widely adopted yet (please note I am basing this off my area and what I have found, your immediate area could be slightly different), at this time the only "adoption" I know of is my own house where I have slowly began integrating the IPV6 into my network, and yes I even feel it is complete over kill for a home network standpoint, but I also have a job in the IT field so I try to keep up with technology to keep competitive in the job market....hence me always wanting to learn new things and play with new tech as it comes out...

    Please note I would suggest just leaving your setting ALONE!! The age of your hardware/device will also play a very big role in the "can you use it" aspect as well, if your device is with in the (IIRC) past 11 years or newer you have nothing to be concerned on, if the device is older then 11 years old (again approximation) you may be using older standards like wireless B, G or N I mostly use wireless AC on my wifi device (Dell Laptop built back in 2012 I believe) that I swapped a wireless AC card into. So if you can consider updating/upgrading your hardware (if your able to) to newer standards and you should again see little to no issues...I haven't had any ounce of trouble and IIRC my ISP is starting to mess with IPV6 and I have had no gripes about it...yet....
