Hi, Im having similar problems to the other people who need help with there ipv6 connectivity.A couple months ago ipv6 was working fine, a couple weeks back it said ipv6 limited ipv4 internet.I can connect to websites and everything i have no problem with that, but when i want to connect to online games(not from the web browser) example: Live For Speed. I cannot get on not even on Limewire. I cannot download music and go on online games. I've tried the regedit thing already. It didnt work, i tried turning off my modem for 10 seconds it didnt work either. Did i say i have Microsoft Vista Home Premuim i share my internet with my sister and her laptop says ipv6 limited ipv4 internet, i have a cable wifi broadband modem. i use netgear to share my internet aswell. It would be greatly appreciated on my behalf if this problem was resolved.Yours sincerely Edi.

Hi, Do you mean that you enable ICS on your Windows Vista machine to share the Internet connection to your sisters computer? Does one or both computer encounter this issue? Id like to confirm if IPv6 is requested to play the online game. If IPv6 is not in used, I think the IPv6 status should not be the culprit. This issue can occur if the wireless router do not fully support the whole networking feature set and requirement of Windows Vista. I suggest that you: 1. Contact the router or access point hardware vendor to ask about a firmware update or Windows Vista Certified device status. 2. Disable Auto-Tuning on Windows Vista machine and check the result:a. Click Start, and type cmd in the Start Search box.b. Right-click the cmd icon, and select Run as Administrator.c. In the Command Prompt, type the following command:netsh interface tcp set global autotuninglevel=disabledd. After that, please check the result.Note: Please re-enable Auto Tuning by typing the following command if the above steps cannot fix the issue:netsh interface tcp set global autotuninglevel=normal Hope it helps.

I did what you said and it worked it changed the status of pv5 to local but the next day when i checked on my computer it said Limited i tried several times to fix it but it didnt go to local. Why doesnt it work anymore?

Hi, Please confirm: 1. Have you updated the firmware of the Router? What is the model of the Router? 2. Does everything work properly when the status of IPv6 connectivity is local? 3. Is IPv6 requested to play the online game? If IPv6 is not required in this environment, you may disable all IPv6 component and clear the TCP/IPv6 checkbox in the Connection Properties page on Windows Vista.To disable all IPv6 component, refer to the following KB article:How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vistahttp://support.microsoft.com/kb/929852

The model of the router is Motorola. When the IPV6 connection said local a few days ago it was the same. i could not get onto the online game, or download.. I dont know if IPV6 is requested to play the online game. I dont think it is.

Have you been able to fix that problem because I have exactly the same problem and don't know what to do. If you been able fix your problem and still remember how you did it, could you please tell me how?
