NaimUniti-Buffering with WAV files

Posted by: stammerman on 27 February 2012

Hi!

 

Reading through one of the other threads relating to streaming I've decided to try ripping some of my CD's in WAV format and the sound is much improved but the Uniti is now cutting out every minute or so when using the wireless connection. I can see the buffering gauge steadily drop down from 100 to 0.

 

The wired connection works fine but then I can't use the Naim app via my iPad.

 

Any ideas? I've only had this Netgear router for a couple of weeks, so may this is the problem.

 

Cheers,

 

Martin

You should be able to use n-Stream on your iPad to control your NaimUniti whether it is connected to your network wirelessly or wired.  I'd try to sort that out before downgrading to wireless, which will not connect your NU to the network as quickly or reliably as wired.

 

My NaimUniti and SuperUniti both have wired connections to my network and I can control both of them from my iPhones and iPad using n-Stream.

 

Cheers

Thanks Ian for the info..................

Same here for UQ

Your wireless connection is bandwidth limited.  Think about it - you're tryng to stream 10 times the amount of data from a WAV file in the same time as a compressed file.  As your new router is presumably 802.11n, you might want to try the Netgear WNCE2001 instead of the Uniti's built-in 802.11g wireless card (more bandwidth and supposedly greater range).  Also, try re-orienting and re-positioning the the router and/or the Uniti.

Good point - Thanks for the info regardng the Netgear WNCE2001. I'll check this out..........

Or better still - go wired.

 

It is not possible to guarantee that a wireless connection will work nowadays - for example, as wireless networks have become more prevalent then it is no longer possible for me to play DVD ISO images from my server wirelessly on my laptop, something that I used to be able to do without an issue!

 

As more and more people set up wireless networks (especially with wireless N routers that try to use multiple channels) then the contention between wireless networks will just become increasingly worse and everyones individual throughput will plummet - of course the hardware manufacturers will sell you kit that claims increased range and power to get round this but what's really needed is *LESS* range and *LESS* power so that your network is contained and doesn't come into conflict with so many of your neighbours...

 

Wireless networking is one of those facilities that sound like you're getting something for nothing but it is a technology that is fundamentally flawed at a consumer level.

Seriously - move away from wireless if at all possible...

 

"More Bandwith" ... which means (at a simplistic level) that as a wireless N device it will try to use channels 1, 6 and 11 which are the only none overlapping channels in the 2.4GHz spectrum however 1 overlaps with 2 and 3, 6 overlaps with 4, 5, 7 and 8 and 11 overlaps with 9, 10, 12 and 13. So what you're doing is trying to use the entire 2.4GHz spectrum that is available - which is fine if you are out of range of any other network but if you are in range of other networks then it means that you have greater contention with them as you're all fighting for all of the airspace.

 

"Greater Range" ... which you may think means that you'll get a stronger and more reliable signal but also means that you bring yourself into the effective range of more wireless networks and therefore have more wireless networks to compete with for bandwidth.

 

...and Ethernet over Mains is as bad. Neither are a good medium to try to stream over.

Spoken like a true single man - SWMBO would have none of it!

you guys really put a G card in the uniti?  Sorry, but that is WEAK!

I have a similar problem with a wired connection, especially with hires files. Also a random crackling or spitting sound, so it is not just wireless connections. I need to phone Phil as this seems to be happening since my NDX came back with its new board. I am sure it must be a network problem more than a hardware issue but the hires cuts out regularly so it's unlistenable.

 

Bring back cd!

"Bring back CD"

 

 Nooooooo!  CD, go to h... and stay there. So glad we have streaming!!!

I think I have found the problem. I have removed the netgear switch and connected everything to the router and touch wood it's working. No drop outs and 100% buffer so far. Problem is I am now one connection short so my office system cannot access music on the NAS. I need a new switch!
