Network problem

[Steve]

I think if the pc and nas are on the same switch it lets the router off the hook

This is getting weird now, I just transferred 2 6gb files and got no network slow down or timeouts.

I have no idea what the problem is now.

Nice diagram but I'm not sure what is going on either.

Ok, I spoke to soon, on this copy I'm getting slow downs. Web sites taking ages to load etc.

My netbook that runs windows xp is connected to the same switch and thats not getting any slow downs, so this means the switch is ok.

Now. I'm thinking a windows 7 problem.

The PC spec for this machine is : Intel Core 2 Quad Q9450  @ 2.66GHz, 4 GB RAM.

I will have to look around the net to see if there's a fix.

This is what I get when copying a file to the NAS drive.

If you are trying to surf on the same machine you are copying the file from it is likely to be contention on the Ethernet interface.

Unfortunately there is not much you can do about that.

Yeah I expect a slow down, but no traffic at all is abit extreme.

Copying the same file on an XP machine does not have the same problem. Looks like Windows 7 still has the Vista network bug 

[pctech]

Could be

My original plan was to upgrade my PC hardware this year so would have Windows 7 to play about with but as always, other things have got in the way.

[Steve]

Didn't the Vista bug relate to the MultiMedia Class Scheduler i.e when multimedia was being used on the PC everything else ground to a halt due to the way the priorities were organised.

[pctech]

Come to think of it I think it was Steve.

I've noit paid that much attention to Vista as it sucks like a good vacuum.

[Steve]

Isn't the same service still in windows 7? I think it is, may be worth disabling the service temporarily just to see.

[psp83]

Tried disabling it. Aswell as doing the following

netsh interface tcp set global autotuninglevel=disabled

Still getting the problem, Guess I'm just going to have to live with it.
