Windows 7: Do I need IPv6 and which ones ?

I'm stuck with a slow file transfer (laptop to Nas) and I have tried a few things like turning off RDC and 'Disable TCP/IP “Receive Window Auto-Tuning” and/or “Receive Side Scaling” in Windows 7' but to no avail. I then read that changing the IPv6 settings may help but I don't know which ones I need and which I don't.

I looked here;

How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7 and Windows Server 2008



As you can see there are a few configurations but I have no idea of the one I need....or in fact if it would make any difference. Help.

IPv6 has been known to have connectivity issue on some networks. Especially those with mixed machines.

You can test if it is the problem by creating a new network connection using the workgroup model. If it works you can then disable IPv6 and kill homegroup

Thanks Ken but I have no idea how to do this .

All that shows you is how to disable certain components of the IPv6 protocol, it doesn't say a thing about this speeding up your IPv4 connection and it's highly unlikely to help your connection speed at all.

disabling ipv6 won't speed anything up. The majority of the time (inexpensive) NAS devices have dog drives. These aren't HA drives and your bottleneck will normally occur in the I/0 buffer Queue on the NAS device.
