has anyone got any idea what I might do to help this

[etrin]

I have a dlink 321 nas and trying to feed movies to a netgear neo550 which uses a 10/100 ethernet connection

Router is a buffalo WG300NH ZR-HP-with dd-wrt flash

I connect the neo550 directly to the nas and get 80Mb and everything plays fine.

I plug both of these into the buffalo router and my thruput drops to 17Mb and stuttering and stopping on play.

WT this doesn't make any since what is going on.

So I plug in a trendnet s8 gigabit switch to the buffalo and plug both the nas and the neo550 to it.

thruput is 22Mb.

Finally I try one last thing I get an old linksys 10/100 switch and plug both devices into it and get 70Mb.

Why am I getting major slowdowns plugging these devices into the buffalo?

Both the nas and the media player can use smb or nfs so I go into the router and say ok its set for smb lets try nfs.


testing on all the above thru the buffalo smb is giving me 17-20Mb and nfs is giving me 28-33Mb

still too slow to play a movie.



again what can I do with the router to get a decent thruput???


I got an email from one person that said he experienced the same problem so he purchased a netgear managed switch and he is now getting 70+Mb thrput.

ok what does a managed switch do in this situation??



thanks for any help and ideas

Try different, known-good, commercially produced cables. If they were hand-made and not correctly terminated (or commercial cables in poor condition - kinked, twisted, crushed, etc.), it can cause the symptoms you describe.

Some devices are more sensitive to bad termination than others.

this just keeps getting stranger and stranger.
I changed out all the cables and still getting crap for speed.
So I put the trendnet behind the router.
The nas is plugged into the router and the media server is plugged into the trendnet.

nas to neo550 80Mb
nas and neo500 both plugged into either the router or the switch 17-20Mb

nas plugged into the router and neo550 plugged into the switch 45-55Mb

Cables didn't make any difference I tried cat 5 and 5a and the same results.
I think after 3 different cables in each device it rules out cables.

this looks like some hack they did on the neo
at first it has a choice of smb or nfs networking.
the smb never worked for most people so now there is no choice.
I made both smb and nfs sections on the nas to see and it recognized all of them.
smb speeds are about 20% slower than the nfs connections.

funny I also tried this I made 2 directories and set them up as smb and nfs
this is just their built in network speed test so it bounces around and not very accurate
but something to compare

smb1 17Mb
smb2 20Mb
nfs1 30Mb
nfs2 35Mb

with it plugged in router and switch

smb1 45Mb
smb2 65Mb
nfs1 70Mb
nfs2 55Mb
these are the highest numbers I saw sometimes it would show as low at 25 the test is very short and just loops.
I tried to watch enough to say an average on the nfs was around 50Mb and smb was around 45Mb
what was really weird was the drive 1 was faster on nfs and drive 2 was faster on smb
that didnt' make any since either.


I don't understand that at all.

Entry Level NAS' based on propriety firmware (OS), or drives connected to a Router's USB, usually s*x.

This is the main reason to why that many of us use computers as file server, or opt to expensive stand-alone NAS'

Try temporarily to put a computer with a movie (as an experiment) instead of the NAS, and do the same manipulation measuring real functional file transfer.

ok but none of that answers the question

nas>>>>neo 70Mb

nas>>>Gigabit router>>>>neo 17Mb

nas>>>Gigabit switch>>>>neo 20Mb

nas>>>Gigabit router>>>>>>Gigabit switch>>>>neo 40+Mb

here is the last thing that blew my away

nas>>>>>>10/100 linksys router>>>>>neo 70Mb


so its the gigabit router and switched that the neo doesn't like
this neo is a 10/100 but that would not answer why the slowdown.


WTF is up with that?????

and there are a lot of people I would say reading post on other forms 50% that are seeing 70Mb and the other 50% are seeing 20Mb
so it has to be something this netgear neo is doing.
Like I said I received 2 post from people who said when I swapped the gigabit switch to a managed gigabit switch it fixed it.
