Windows 10: Windows 10 PC Loses it's IPv6 Address after Reboot

My Windows 10 PC loses it's IPv6 Address after I turn off my PC or I reboot it. The only way to get it back is with the command: "netsh winsock reset" and a reboot afterwards.This has persisted through multiple Windows Updates. Other Devices on the same network have an IPv6 Address, only this computer has this problem.Current Windows Specs:Edition Windows 10 ProVersion 21H1Installed on ‎15/‎10/‎2020OS build 19043.1237Experience Windows Feature Experience Pack 120.2212.3530.0Has anyone experienced something similar? Or knows what could be the issue?

Windows losing IPv6 address after ~10 minutes

When I initially connect to my home network my windows PC is assigned an IPv6 address - however after a few minutes it loses this address! I seem to have similar behaviour on multiple hosts using both wireless and wired connections.

My router is an Asus RT-AC87U.

How could it be losing the IPv6 address? How can I mintor / diagnose this issue?

Update:
Based on @grawity's suggestion below I ran wireshark on this. Sure enough I see a Router Solicitation message and a Router Advertisment message with a Router lifetime of 600 seconds. After 600 seconds my computer drops its Ipv6 address.

What is supposed to happen? Should my host send another Router Solicitation message? Or should the router periodically resend the Router Advertisment message?

Update 2:

• RFC 4862 says that Router Adverticement messages should be sent periodically.
  

 

Windows 10 can not get IPv6 address automatically?

Hi all,

hopefully someone can help me and figure out what is wrong. I have been trying to search online for help around similar issues but nothing seems to match exactly my problem and there is not many "near" solution to try.

I guess the problem started around august after some sort of update to windows 10.

I am a network professional and been using IPv6 with DHCPv6 for a couple of years without any problems. So keep this in mind before suggesting any "stupid" ideas about check your ISP or router, I know they are working since all my other devices work. Also
I verified via wireshark, that my current Windows 10 computer does not send any DHCPv6 packets until I manually run the command ipconfig /renew6 multiple times. And after I finally get the computer to send the DHCPv6 packets, I get a response from the router
and IPv6 connectivity is restored. The IPv6 works for a half lease time and after that it deprecates because somehow windows fails to renew it on half the lease time. I can again get it to work after manually using ipconfig /renew6 for multiple times until
it runs without any error messages. The errors I get from ipconfig is listed below:

• An error occurred while renewing interface Local Area Connection The parameter is incorrect
• An error occurred while renewing interface Local Area Connection The semaphore timeout period has expired.
• An error occurred while renewing interface Local Area Connection Function failed during execution.

Now I´m not an expert on software, but could it be that the automatic process of renewing IPv6 address also fails to the same errors and somehow it does not try again automatically so eventually I lose IPv6 connectivity completely until I run ipconfig /renew6
manually about 3 times until I get a clean exit and the address is renewed.

What is causing the errors? And are these the reason why windows fails to renew IPv6 address? At the same time IPv4 DHCPv4 is working flawless.

Any help would be greatly appreciated!

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
