Stuttering video from 323 just streaming from a computer

Hey guys,

I am at a loss here, D-Link level 3 guys don't know what to do either. Right now my 323 is connected with a gigabit connection to a Wireless N router (TRENDnet TEW-633GR). It is set-up in RAID 1 with 2 1tb drives. Basically, what I am trying to do is stream a video to a laptop with a N network adapter (macbook). The video is a low-res, small file, not a 1080p monster.

If I navigate to the 323 and try to play the video from my laptop, it will play, but with lots of small stutters. Now, in an attempt to isolate the problem to the DNS-323, I copied the video file to another Laptop that was connected to the network through wireless G card. Now streaming the video from the wireless G laptop to the wireless N laptop works perfectly, no stuttering at all.

In summary

DNS323---gigabit ethernate--->wireless router----802.11N--->laptop =stuttering video
laptop1---802.11G-->wireless router----802.11N laptop=perfect video

I am running 1.06 on the 323 as well. ANY ideas would be GREATLY appreciated.

Thanks in advance!!

Does the problem occur when you try to stream to a wired computer?

Re: Stuttering video from 323 just streaming from a computer

Thanks for the quick responses. There doesnt seem to be any problem with wired connections. I do have one question, I am beginning to wonder if Wireless interference could be the crux of the problem. There are approximately 20 wireless G networks in sight (damn apartment complex). Although I seem to be on a different channel than the rest of them, do you think this would create stuttering?

Re: Stuttering video from 323 just streaming from a computer

Yes - interference on a wireless network is a potential problem, it can cause errors which effectively reduces throughput.

Next - with 2.4 GHz wireless, a network on any given channel has the potential to interfere with every other nearby network within 4 channels of it, in effect reducing the number of available channels to three - 1, 6 & 11 - a network on #3 will interfere with networks on 1,2,3,4,5,6 & 7.

Re: Stuttering video from 323 just streaming from a computer

try using 802.11B, or even A. noone uses them, and they're fine to stream with - one old p.o.s laptop at home streams a given 700mb movie fine with B, while a 3 month old laptop stutters like all buggery on N. There ARE 2 surrounding networks though, as well as phones operating on 2.4ghz

Just so that you're aware of it - 802.11b also uses 2.4GHz and is subject to the interference mentioned in my previous post - 802.11n can be either 2.4 or 5 GHz (same as 802.11a) so you do need to verify before buying.

Re: Stuttering video from 323 just streaming from a computer

hmm, my router (TRENDnet tew-633gr) is wirless N, but seems to be in the 2.4 range, rather than the 5. The router can't do a. Can anybody think of a way to verify that it is wireless interference rather than a DNS-323 or router issue...?

Re: Stuttering video from 323 just streaming from a computer

What is your throughput on wireless N. How long does it take to copy a large file and at how many MB/s is it copied?
You need about 2MByte/s for XviD movies. And about 5MByte/s for HD movies. I say "about", because it is very dependant on the compression of the video file. The famous bird-scene on the Planet Earth Blu-ray rips needs about 10MByte/s.

I found that my Network could only deliver 4MByte/s on 5Ghz. On 2.4Ghz wireless N it could deliver 9MByte/s, even though all channels are over-populated. I picked a sort-of free channel using inSSIDer. http://www.metageek.net/products/inssider
