IPv6 multicast flood during sleep from i217-LM

No answer I'm afraid but I can confirm the symptoms and the cause. It's definitely the Intel i217-LM chipset that's causing the problem when the PC's go to sleep.

INTEL ARE YOU AWARE OF THIS PROBLEM AND IS THERE A FIX? It is a REAL issue that has the potential to kill a network and, believe me, it's not easy to track down the cause. We have spent 30+ hours on investigations to nail this problem to your chipset and it would be nice to know whether there is a fix. It seems to affect machines from all manufacturers (Dell and HP to name two) so it's not a PC manufacturer problem, it's an INTEL PROBLEM. Please provide a fix ASAP.

Hi,

We found *exactly* the same case on HP EliteONe 800 with I217LM Ethernet.

12machines killing totally the local area network during 15 minutes once a day !
See ICMPv6 'Multicast Listener Report' messages are flooding the local network

Answer of Microsoft is : change Ethernet card or turn off IPv6 or turn off sleeping state ! But it does only mask the REAL problem.

PLEASE Intel, could you give information about this issue ?

Yes Intel is aware of this issue. Please retest using our latest LAN driver version 19.0 release, available from our Download Center, and let us know if this driver helps resolve your issue. Thanks!

I have the same problem with Intel I217-LM NIC. I am using Win 7 64 bit OS and am looking for the driver update to fix the problem with ICMPv6 multicast listener flooding. All I see is the drivers for  Win 8. Can you point me in the right direction please. I initiated the temporary fixes of disabling IPV6 and Wake on LAN...
