Latest nStream update

It's possibly showing under "Other" and just missing the required driver.

Hi Ray,

It sounds like Windows hasn't detected the NDX or you ran the updater app before Windows had finished detecting the device.

As has been suggested here, if you go to Windows device manager - Right-click "My Computer", select "Manage", select "Device Manager" and open the "Ports (COM & LPT" tree - you should see a COM port there when the NDX is connected and it should vanish when it is disconnected.

Once you have a COM port showing under there then you should be able to see that COM port appear in the drop down list in the upgrader app.

Cheers

Windows XP, Vista and 7 should all have the required driver by default - we chose the chipset specifically because it was reliable and Windows came with drivers for it (or they were at least available from its automatic installation function).

If it isn't appearing as a COM device then please contact us at "support@naimaudio.com" (as per the sticky at the top of all the forums) and we'll do our best to assist directly.

Cheers

Hi,

There is no specific USB to RS232 adapter that we recommend - the days of flaky USB to RS232 interfaces seem to be pretty much gone and every adapter I've tried recently has been fine.

For my own use I tend to look for interfaces with FDTI chipsets as a preference (or Prolific - they've always been fine for me too) but I haven't come across any that I would say to specifically avoid.

Cheers

If you are using the new functionality of the nStream app and have this problem then try going back to "UPnP compatability mode" and see if you have the same issue ... when using the new functionality the iPad / iPhone / iPod Touch become the control point rather than the NDX.

I suspect that the issue is the SuperHub - they're pretty poor devices, their WiFi stability is shocking and they drop UPnP traffic left right and centre especially by WiFi. We've had no end of issues with them - dropping out Internet Radio stations being one of them and Virgin's response has generally been "Stick it in Cablemodem mode and put in a different router" - I long since set mine to Cablemodem mode and use a Draytek cable router behind it however Apple have recently updated their Airport Express so that it has dual Ethernet ports (LAN and WAN) and does dual band simultaneous (2.4GHz and 5GHz) WiFi and I was going to try to get one of those and try it over the weekend but didn't get around to it.

Phil

What were the problems you had? Can you let me know please? Can you email me on phil.harris@naimnet.com ?

Cheers

Hi Phil - Airport Extreme works brilliantly with the confounded 'superhub' (where exactly is the super?) - and solves most of the problems. I've ended up with double NAT though and will need to amend the settings on mine.

Hi Phil,

I would be interested in your thoughts on a problem that I highlighted earlier up the chain of comments. I will restate the point:

The nStream app flagged a minor update last week, dated 21^st August, so I made the update on my ipad3 and now I have a problem. When viewing music to make a selection, I can view as either a vertical list or display as a sort of table. The vertical list is fine but when I view as a table (which I prefer) the motion of the icons are awful. Navigation movement is sluggish and lags a lot behind my finger movements. It also moves in a juddery way, like the refresh rate is really low or something. I can’t now use the table view as it’s quite nauseating with the flickeriness. The vertical list view is absolutely fine. Both view modes were fine before this minor update the other night. All other moving navigation graphics within nStream and all other apps are absolutely fine.

A comment on this thread from ‘Lebowski’ suggests that it’s not just me, although it may be specific to the ipad3?

Hi,

Can I flag up again that support requests should really be flagged to support@naimaudio.com and then we can get them, log them and track them - things flagged up in the middle of threads here on the forums will only get seen by chance.

I did flag your post up to Tom (the author) though at the time but it doesn't appear to be a known issue (i.e. it's not reproducible on any of the kit here) ...

Cheers

Phil

Yeah - the Airport Extreme is fairly pricy though and I like the internal PSU on the new Airport Express - it's very "AppleTV" ish but in white. At least with Apple devices at both ends of the WiFi link you do seem to get less issues.

If you're getting double NAT then have you actually got your SuperDud set to "Cablemodem mode"? (Bottom of the left hand side list of options in advanced mode.)

If you have you should end up with a dumb device (OK - you started out with a fairly dumb device in the first place but it should now be even more lobotomised) that only has one working Ethernet port and no WiFi / DHCP etc.

Phil

( ... oh - and I think it's an ironic "Super" in "SuperHub" in the same way that it is in "SuperNoodle". :hehe: )

Thanks for your effort Phil. I wonder if Tom was able to test with an ipad3. I'd be interested in any ideas from anyone as to what might by wrong with my arrangement. Although my setup is about as 'default' as it's possible to get. I bought the ipad specifically for controlling my NDS, downloaded n-Stream and that's about it.

Cheers,

Gav

Yes - he has access to quite a stash of Apple products including several different software versions of all iPad variants ... unfortunately Apple give no route for developers to install different versions of iOS on devices for testing so we have to keep lots of the same units but just with different firmware versions on them but there's no way that we can have every combination, just a selection.

Cheers

Firstly, I appreciate your contributions to this forum. It really adds to the benefits of being a Naim owner.

My question: like quite a few here, I'm currently using a Virgin Superhub, though I'm thinking of switching it to modem only and perhaps buying an Airport Extreme or similar. But an oddity: my iPhone and iPad won't see the SU through auto-searching, though I have no difficulty connecting using a manual connection to the IP address. The name of the SU does not appear, just the IP address, even on the SuperHub's list of connected devices. This has been true on all versions of the App I've used. I should mention that I'm currently using the dreaded Internet over mains, though you'll be pleased to hear that next week I will move to a directly wired connection. Any thoughts - it's not the end of the world, I admit.

Paul

Hiya Paul!

Correct ... it's a "function" of the SuperHub ... doesn't allow UPnP discovery from the wireless to wired sides - hence my continued suggestion to stick the thing in cablemodem mode and use a decent router.

Phil

Yes, like a while back my Virgin "On Demand" service seldom being available. And these people want to run the NHS?! But that's for another thread...

I used to have that too ... according to them it wasn't a problem with their network or my STB but it did miraculously just clear itself pretty much immediately after I phoned them once my initial contract was up for renewal and told them I was cancelling my service because it didn't work still...

I just paid to get a TIVO in because the V+HD box was so buggy and would take anywhere up to five minutes before it would allow me to do anything after using any "Delay TV" function - and now find that the TIVO itself is often as laggy as hell (a few seconds from pressing a button on the remote to getting a response on screen).

(...and if anyone out there can tell me how to get it to *ONLY* record the new airings of "American Chopper - Senior vs Junior" and not every damn episode I'll be incredibly grateful! )

Phil

Phil

I have a TiVo which I don't find laggy. There's a big software update taking place at the moment which extends recording options. I've had it, and if you go into Settings/recordings/Default Recording Options, you'll find a setting to do exactly what you want, which is Record 'New Only' episodes. If youhaven't had the upgrade, I'd say it's imminent.

Cheers

Paul

Ah cool - mine was apparently updated at the weekend so lets see if I can find that.

Cheers

Phil

Hi Tog, yes upnp and airplay use something called muticast IP packets for discovery. Muticast has to be handled in a speific way by switches and routers. Some cheap products - certainly some cheap 'so-called' consumer routers simply don't comply with the core TCP/IP rfc's and fail to honour muticast (this doesn't bode well for IPV6 in consumer land...). However Apple have have produced two great devices (credit where credit is due) with the Airport Express and Extreme and they support multicast packets between the LAN and Wifi interface - required for Airplay... and so these devices are superb at supporting Upnp as well and provide the correct connectivity through to the Nstream for discovery.

However there is still a bug with the latest Nstream which I suspect is handle/buffer/timeout related which prevents the doscovery algorithm working correctly in some scenarios. The previous version of Nstream worked a dream and appeared quicker - but alas did not contain the playlist validation function.

Hi Simon (glad to see The Hood is back as your Avatar :-))

That might account for the not infrequent "Streamer not responding" message that I get on IOS devices - a reboot or simply waiting 15 minutes usually solves the issue.

On the subject of NATs I will put Superhub into modem only mode as I have found that placing my main AE into bridge mode upsets quite obviously upsets the switch that manages the separate server/ streamer spur of my network. (I should have seen that one coming!)  However, I have heard that even in modem mode the SuperHub can still cause problems.

Tog

Hi Jon,

Your simple answer is that our update process is appropriate for the design of the product.

Best Regards

Phil

Hi Simon,

Can you provide me with some information ( to phil.harris@naimnet.com ) relating to this bug that you say that the new version of nStream has as I am unaware that there actually is an issue with the app in this respect...

Cheers

Phil

Hi Tog,

Yes - consumer level kit is frequently the cause of odd issues ... one issue that rears its head with our high end multiroom product ("NaimNet") which uses IGMP very heavily is that some domestic routers and switches don't have the ability to handle IGMP traffic and take the simple workaround of converting it to an overall multicast.

Once in cablemodem mode all the routing and WiFi facilities of the SuperHub are disabled so there should be no SuperHub induced issues - can you point me towards the information that you are referring to so that we can take a look and - if appropriate - I'll try to get it filtered back to the appropriate devs in Virgin Media?

Cheers

Phil

Hi Phil - sorry I wasn't clear at all - the network spur managed by my switch is connected to the AE not the SuperHub - when the AE was switched to bridge mode the spur was effectively cut off - stupid mistake really.

The 'streamer not responding' message has been there for some time but seems to have got worse under latest nStream. It is infrequent but annoying - sometimes rebooting the IOS device works - sometimes the network - sometimes the streamer itself. About half an hour seems to do the trick as well.

internet > superHub > AE1 _AE2 ( wireless multiple Mac household) -

AE 1 > MacMini Plex Server attached 

AE 1 > switch _ TogServe (Vortexbox Server) - Naim Uniti (not updated yet)

AE s are newish models and broadcast in dual band.
