This is an IPv6-version of the following question:
After moving from IPv4 to IPv6, I've noticed that my IPv6 connections would drop all the time (e.g. overnight). I've now finally caught it dropping after only a couple of seconds when IPv6 connectivity was temporarily lost on the remote host.
It would appear that creating
TcpMaxDataRetransmissions, with a value like
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters, has no effect in Windows 7 (unlike the corresponding IPv4 setting). Why?
How do I prevent the IPv6 TCP connections from dropping so quickly? My IPv4 connections remains active for minutes during the temporary periods of no connectivity, after creating the same value (and a reboot) within
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters, as per the referenced question.
