Router with gigabit lan makes HD playback stutter

Router with gigabit lan makes HD playback stutter
I have just bought a new Netgear WNR3500L router with gigabit switch. Connecting my Synology DS210J and my Popcorn Hour A-110 to the switch HD playback stutters alot. TV series in 720p I can watch for a few seconds with audio and no stutter. 1080p movies are worse and if I skip forward hell is breaking loose. If I then change the setup using one of my older routers (Trendnet and Asus) which both has 100 Mbit lan the playback is perfect.
Is there some setting on my router I should change or anything in perticular that the Popcorn Hour A-110 doesn't work well together with? I really would like to be able to use the Gigabit lan and wireless N on my new router

RE: Router with gigabit lan makes HD playback stutter
Check if your router has QOS and if set on auto? for it is that they usually give priority to the www before streaming.

I've turned off QoS on my DLink DIR-655 for it did not work really well

I'm running the latest dd-wrt. QoS was by default disabled so sadly not that causing my problemsconfused

I have a DLink Dir-655 and it appears it may be causing HD audio DTS @1536 Kbps and DD @ 640 Kbps from a PCH C-200 to stutter every few minutes.
I am playing M2TS BD folders stored on either a HP Media Smart WHS server or a desktop computer. They both have the audio stutter. If I play the same BD file from an internal hard drive in the C-200 there is no audio stutter.
The video is perfect and never stutters.
Are you having any problems like I described ?

RE: Router with gigabit lan makes HD playback stutter
If I place one of my older routers with 100 Mbit switch between the new router and my Synology it works perfectly. I really would have liked it to work with the popcorn hour behind a 100 Mbit switch. That way I wouldn't been loosing the gigabit advantage of the Synology. I'll try borrowing a 100 Mbit switch to see if that makes any difference

I have the exact same problem you described. My setup is this: Kaifa ep6000b and Linksys WRT54GL (tomato firmware) router hardwired. Streaming from PC to Kaifa is perfect even with 20 GB file. I can jumped to 90% of the movie and after a few seconds everything is all caught up.
Wanted to upgrade to wireless N and 1 GB router. Bought Asus RT-N16. Now the only problem I have is streaming (through LAN). It starts stuttering within a few seconds of the movie starting. Forget about jumping to certain scene. Flashed all kinds of firmware on the router and same thing happens. Swithed back to Linksys and everything works again. So I thought the Asus is defective.

Now that I found someone else has the same problem, it's gotta be 1 GB and 100 MB. Right now I am stuck using 100 MB router.

RE: Router with gigabit lan makes HD playback stutter
UPDATE

Everything is running perfectly.

This is what I did:
Change flow control on your NIC to TX & RX. Leave speed and duplex at auto negotiation.

My setup:
PC - 1Gb NIC
ROUTER - 1Gb
SWITCH (x2) - 1Gb
Patriot Box Office - 100Mb
Kaifa EP6000B - 100Mb
PCH C-200 - 1Gb

PC -> ROUTER -> SWITCH (1)
PBO -> SWITCH (1)
KAIFA -> SWITCH (1)
SWITCH (1) -> SWITCH (2)
PCH -> SWITCH (2)

I actually think this is faster with the flow control setting. I can jump to any percentages of the movie with only a second delay before the movie runs normally. Before, it seems to take a 3-4 seconds. This is with a 30 GB file.

Hope this helps anyone with the same problem.

Seems like you had problem streaming from your PC?
My problem is when I am streaming from my Popcorn Hour A-110. I "solved" the problem by connecting a 100 Mbit switch between my Synology NAS and the 1GB switch withing the Netgear router. That way playback works but transfer speed is back to 100 Mbit :-(
It would be nice if there were some setting on the Popcorn Hour that could solve this issue

RE: Router with gigabit lan makes HD playback stutter
I have the same configuration and problems. My problems were solved by changing my NFS links to:

nfs-tcp://ip.of.your.nas:/volume1/Media

Hope this helps.

I am having similar issues with my synology ds411j streaming to the A210. If I put a gigabit switch anywhere on the network it causes stuttering. Removing it allows everything to work perfectly. I don't really understand the above help (new to all this networking/streaming stuff). I am wondering whether the above advice will help my situation but sure where I change NSF links. The nas is using NSF.

1) If you haven't added a share yet follow step 2 in the above FAQ and then add (-tcp) to the share path.

RE: Router with gigabit lan makes HD playback stutter
On the network share settings I changed NFS to NFS-TCP which has fixed the stuttering problem.

RE: Router with gigabit lan makes HD playback stutter
I'm so glad i'm not the only one weigh this problem. Had so many headaches since building my first nas and trying to get all my media running from it.

Really hoping this simple solution works for my a when I go home this evening on a pcha110.

Out of curiosity, what is it that cause the problem and why dies adding those 3 letters make the difference?

RE: Router with gigabit lan makes HD playback stutter
Max,

I wish I had the techinal knowledge to answer your query ! Sadly I don't - In my case it's been a game of trial and error, plenty of research on the net and plenty of help from the community.

Everything is working like a charm though, sticking a disc in the bluray player seems very clumsy now ;-)

On a side note - I bought my HDD's (4 x 2tb ) just before the prices rocketed so feeling ever so slightly smug !!
