Windows losing IPv6 address after ~10 minutes
up vote

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 thatRouter Adverticement
messages should be sent periodically.

Using Wireshark (capture filtericmp6
or display filtericmpv6
), can you check how often you see a Router Advertisement, and whenever you see one what "ICMP→Router lifetime" & "ICMP→Prefix→Valid lifetime" does it show?

Go to test-ipv6.com. If it says that your ipv6 ICMP is filtered, then see this article. If this helps let me know and I'll put up a detailed answer.

@grawity - looks like you were right, the router advertisements are timing out. I've updated the question.

@harrymc: That only tells one whether ICMP from WAN is filtered; it doesn't necessarily correspond to multicast ICMP within the LAN itself...

Ok I think I figured this out:
My router has a flag that says Enable Router Advertisement
. This was enabled - but by switching it to disabled (restarting) and then back to enabled (and restarting again) seems to have done something to the router and now wireshark shows it sending Router Advertisement
messages every few seconds!

Every few seconds is way too often. (Drains Wi-Fi devices' battery, among other things.) Normally it should be every few minutes, with the "Router Lifetime" field being 2x-3x the interval. If you saw that "Router Lifetime" is 600s, expect the advertisements to be automatically sent every 200-300s (plus whenever a PC requests/solicits one).
