Trouble streaming hi-res audio:

Well, I tried a few things but to no avail. I tried increasing the buffer to 500 ms, but that didn't work. I tried switching out the router for a different one, but that didn't work.
I'm really stuck. If I play to the computer, it works. If I stream it to my Naim streamer, it keeps getting interupted.
The wireless signal is very strong. I've tried PoE before, but it is a solution I'd rather not use right now. Especially, because this *should* work.
I'm flummoxed.
Samson:
MC may not be the culprit esp since the wired connection works but turn off any DSP or other processes/conversions that may be causing delay.
24@192 is about 4.6 Mbps [EDIT, 9.22 Mbps for stereo] data transfer or bandwidth which should easily be handled over most wifi even with losses for this and that.I am not a network expert but possibly there are also latency or other issues.I dont think "signal strength" per se is a good enough indicator of performance.When I have task manager open with network performance tab the wired connection is steady and strong where wifi speeds vary widely, in excess of 120 Mbps (so it says) and way down below 50.I know when i stream HD video I get more buffering occuring.Maybe get some proper software tools and measure both bandwidth and latency.
Hope it works out.

Sorry, I keep losing this thread expecting it to be in Media Network. ?
If you check the ‘Buffer Level’ via the front screen on your Naim you can watch and you will see it drop away and the music stop until it starts to fill again. If this is happening, which it surely is from what you say, then you have a network problem, data is not being received quickly enough to maintain playback. You know this already I’m sure.
In your Naim manual you will read a note under the heading ‘Wireless Network Connection Set Up’ which explains that only one wireless ‘leg’ should be used. I am sure that someone will say that they are using more than one and good luck to them if they can, unfortunately your environment is not suitable for you to do so, or so it would appear.
I can also say that MC will not work as a control point for the Naim. I have just set my system up as such to test (although I knew this would not work) and it does not, it may play a track depending on how MC is set up but then it stops. This is as I understand it (no expert remember) because all Naim streaming products are designed to ‘Pull’ music from the server; you cannot ‘Push’ to them. Consequently, they do not communicate with many control points as they would need to for this to work.
However, all Naim streaming products are designed to work using a control point loaded on an Apple iOS device, iPad, iPhone or iPod and they supply a free app ‘n-stream’ to enable you to do this. There is a stated intention to supply an Android version of n-stream at a future date, this may be a big help as they can be run from a desktop I understand, but well, I won’t be holding my breath.
I suspect that you will be aware of all or most of this but I can assure you that I have spent a couple of years trying to developing a solution to this (I do not use any wireless) and there is no easy answer.
Final thought, if an Android solution is of interest to you, although I have not taken much interest in it myself, I believe that a chap named Bubblegum who posts both here and on the Naim Forum on occasions may have developed a program that will run on Android and work with n-stream to operate Naim kit amongst others.
Good luck
Peter

Again, Thanks for the responses. As far as posting in Media Network, chalk it up to Newbie error.
So, yes, the roundtrip between NAS to Laptop (wireless) and back to Naim (wireless) is killing me. (Incidentally, the Naim is a gigabit wired connection, so the two wireless legs are to/from the laptop back to router).
I can use MC to play to the Naim (I'm doing it now w/o a problem), it's the high-res files that kill me. I converted some to FLAC and the playback was better but still gapped, just not as often.
My wireless card reports about 50 Mbps, which I guess just isn't enough bi-directionally (it does work if I play on MC on my laptop).
I will definitely check out the Android solution you mentioned as I am not a Apple guy...hopefully that will work.
I may also try out a newer router (I'm using a Cisco WRVS4400N and it is end of life, and has some bugs that they aren't going to fix).
Of note is that I did get somewhat better response when I changed from a 20MHz bandwidth to a 40MHz bandwidth, but not enough joy there.
Samson, you actually need to double your number for data xfer rate for stereo ;). Still, you'd think there would be enough.
Maybe I'll give PoE another shot.
