View Full Version : Gbit not working at all
First off all, i know Gbit support is still experimental for the dune.
But i also know that some users have it functional.
I am experiencing some really weird problems here.
I've also posted this mssg in another thread, but seeing that is is out of place that and that i have no clue on how to continue from here on i'm dropping it in here as well.
Did some speedtesting and got some really strange results with my Prime 3.0
Tested every possible setup and all were maxing out at 11Mbps, wich got me wondering.
Since 11Mbps is the max off a 100mbit connection i did some snooping around in my switch and noticed that the Prime always stays in 100mbit mode on my Linksys SLM2008 switch.
If i force the connection to Gbit it doesn't obtain an IP adress in my network via DHCP and if i set the IP manually it just wont connect.
And another wierd thing i noticed is when i switch the dune from 100mbit to Gbit.
If switching would work properly the player should loose it's connection when switching from 100mbit to Gbit. This must happen for it to get the new speed setting from the switch. But it doesn't, it stays connected at 100mbit on my switch set to autospeed. It never reinitializes the connection when i switch between 100mbit and 1Gbit.
That gives me the feeling that Gbit is not supported at all on my unit.
But the strange thing is that Gbit & 100mbit is done by the same module in this unit, so if it was a defect i would suspect the network wouldn't function at all.
Is it possible to verify this somehow, i.e. by telnetting with the player or something like that ?
Should not be setup related i think, since all connections work flawlessly on Gbit with CAT5e & CAT6 cables in my network setup.
Feeling a bit stumped here.
Any advice or help is welcome.
+1 I have the same questions. Sidenote:
When I enable 1gb experimental I only get 3MB's and 10MB/s when I have 1gb disabled. This is with SMB and NFS.
Have you tried restarting the device with 1Gb on? Does it still get only 100Mb connection?
Tried all possible scenario's and all i get is a 100Mbit FDX connection to my switch.
Cold boot / Soft reset with both 100mbit and Gbit & both autospeed and forced Gbit FDX on my switch.
I'm really drawing a blank here.
And in retrospective, this situation was the same with inital FW of the Dune and the new Beta i've got installed now. Just never noticed it at the beginning.
Playback works flawlessly but still Gbit is faster :)
So how should be the network parameters on the Prime V3, I know someone who (till now) can't stream any BD rip from his NAS synology (NFS Shared) ?
As far as we know, some GBIT issues relate to timing issues and falls back to 10/100 and this could ahppen in both HDI Dune (automatically) or on the switch level... (negotiating does not agree on gbit and falls back to 10/100)...

sorry I'm not sure if this an answer for my question, I just wanted to know how the V3 network parameters should be set, I've got the V1 (with the gigabit option) & it seems to have changed a bit.
I'm trying to help someone (who can't speak english) from another user forum.
Every BD rips he's trying to play are stutering
It wasn't an answer on your question... (your response is off topic about your frend from another forum having issues with playing over NFS a BDMV folder...)
If you can stream other files but not BDMV, then something is wrong with your BDMV files...

That may be the case, but that doesn't explain why the dune doesn't drop the network connection when switching it from 100mbit to Gbit mode.
If you switch network settings the connection should be dropped and reinitialized, this is something that can't be done without disconnecting as far as i know.

Pls. Mal, do you have a possibility test it with other Gbit network active device (switch, router) such as your Linksys switch?
Seems, that HDi donīt correct implement Gbit protocol and a lot of switches/routers automatically go to 100Mbit connection.
With initial FW for Dune 3.0 I had different results between Gbit/100Mbit setting on Dune.
But only on Netgear Gbit switch.
Any tests on FW 091211_1311_beta.
(Iīm afraid, at divxplayer pass time another speed. From announced 48 hours are more than 144 and still any tracking number.) :-(

Hi,
sorry for being off topic too - it might help
i have read the some switches can causes issue and are not fully compatible with certain hardware,
I have the following switch but don't have a HDi player yet to try out but I would say the this switch I read a lot of positive about and works well my PC gigbit (marvel & intel) and Qnap nas drive gigabit ports also PS3.
D-link DGS-1005D
ftp://ftp.dlink.eu/datasheets/DGS-1005D.pdf
I am waiting for my Billion 7800n Gigabit Router/Modem to arrive to test on other hardware (100/10) to see if it helps.

So, something with HDi Ethernet implementation is wrong...
Hdi Dune 1.0 with FW 091211_1311_beta
- with additional 1Gbit modul
- information page: IP / connected / Gbit Ethernet
and look on screenshot from smart Gbit switch:
http://i907.photobucket.com/albums/ac271/rudku/Dune10_Gbit.jpg
Only 100 MBit, and Link status showing "Down" (= no connected).
This screenshot was taken during streaming movie from NAS to Dune
Changed cable (both Cat.6) and port on switch : 1000FDX
Seems the GBit connectivity on Dune 1.0 is OK.
Quick Read Test:
- SMB 13MB/s
- KNFS (UDP) 9,3MB/s
(same results such as yesterday)
Note:
I must warn.
I recommended smart switches for special settings, polish network, and checking issues, on one side.
But "managened" switch is dangerous thing in unauthorized hands, on other side.
Published screenshot in previous contribution is shining example - during change of Port Description (from Tvix to Dune :-)) I created the fault in setting, from Auto to 100M...

1Gbit/sec didn't work for my situation either.
For a few seconds the player tries to connect at 1Gb/s and then it falls back to 100Mb/s
Tried it also at my friends place, same result.
The 1Gb/s is not correct supported by the Sigma chipset at the moment I think.
I connected the player to my Synology NAS and it has 11 MB/s throughput at NFS and SMB. So if 10 times faster network (900% more speed) connection results in 20% more throughput, it makes no sense...
The 1Gb/s is not correct supported by the Sigma chipset at the moment I think.
You right, because all Sigma chipsets has only 100MBit support (=embedded card).
But I tested on Dune 1.0 with additional GBit module, which is outside a Sigma chipset.
We all know that Gbit is not officially supported by Sigma.
But seing the nice results we were all getting with the 1.0 versions running on Gbit ( speeds approaching 20Mbps ) i was assuming that this would be the case for the 3.0 versions as well.
But as far as i can see for now, i have a nice option in my menu that doesn't do squat.
That's what's got me wondering if it does work at all.
And being that the tech's from HDI already implemented their own version of Gbit support on the 1.0 models on top of the Sigma SDK i was expecting to see the same for the 3.0 models.
Since the basics of the player are pretty much the same, only it's faster ( wich in turn could result into even higher NW speeds ).
But i'm going a bit OT here.
The thing that really puzzles me is why the player doesn't drop it's connection when switching between network modes. This is an indication that the function does pretty much nothing.
Anybody who got Gbit working who is able to check what happens when they swicht Gbit on/off on their router and/or switch ?
I don't have any additional HW available to test it any further.
Only have a linksys SLM2008 Gbit switch on FW 1.0.1.
I've seen reviews with FW 1.0.2 on it, but i can't find it anywhere on the Cisco website.
And my router is only 100Mbit.
I have a Netgear Pro Safe 8 Port GS108 GB switch. When I enable experimental 1gb the switch has 2 lights on (to the PC, to my NAS and my Dunes 3.0).
Meaning that it has become a 1gb connection. When I disable the experimental 1 gb my switch show only one light on each connection, so a 100MB/s connection. The Dunes does something but in my case not a good thing on 1gb, hence the experimental.
As mentioned here by me, I get loosy speeds with the 1gb enabled. Also my Dunes 3.0 do become unstable, NFS shares do not work all the time, when I click on them and I'm getting some kind of black screen and then the dunes are falling back to the main menu. I also have random crashes.
I did test everything with my W7 pc->SMB and Hanewin NFS and my Thecus N5200 NAS ->SMB and NFS.
I going to try now another 1gb switch which I upgraded from back in the days when the pch-100 did came on the market and also many 1gb switches weren't good for the pch-100.
The Netgear GS108 was good so far for all my mediaplayers I had, also for the Dune 1.0 (I got 15 MB/s on it with NFS).
BTW:
HDI website for the Dune Prime 3.0:
Dune Network Playback Accelerator: special optimizations ensuring best-in-class network playback performance for the Sigma Designs 864x platform and enabling smooth playback of any supported kind of media content via any network protocol (including NFS and SMB) in both 100 Mbit/s and 1000 Mbit/s networks.
HDI website for the Dune Prime 3.0:
(*) 1000 Mbit/s support is experimental since it is not officially supported by Sigma Designs 864x chips;
Note: smooth playback of any supported kind of media content (including BDMV folders and BD ISO images) is ensured via any network protocol (both NFS and SMB) in both 100 Mbit/s and 1000 Mbit/s networks, due to Dune Network Playback Accelerator feature.
I asked it before in other threads, never got an answer from HDI, what is that thing the "Dune
Network Playback Accelerator feauture"?
If it is the same thing as with the 1gb module in the Dunes 1.0 it doesn't do a thing or even behave badly in my Dunes 3.0.
I have a 1000 Mb/s network with all cat6 cables.
Still I'm not complaining, streaming with NFS on 100MB/s does work so far.
With SMB I get i/o errors when playing 1:1 bd rips from a bdmv folder.

1. Experimental gigabit support on 3.0 units is not recommended to use, it is recommended to always keep it disabled. You can only enable it to do some experiments if you really want to do it.
We expect that many/most users will get problems with experimental gigabit support enabled, such as:
- Hangups and crashes during network playback or during other kinds of network activities.
- Speed not more than 100Mbit/s.
- Speed much less than 100Mbit/s.
These are the same kind of problems as you can see in Popcorn C200 (which has exactly the same hardware for Gigabit as Dune 3.0: built-in Gigabit controller in 8642 chip (although not more advertised by Sigma), and Gigbit PHY chip on the mainboard).
Some Dune 3.0 users report that they can achieve faster file copying performance with experimental gigabit support enabled (up to 20-25MB/sec = 160-200Mbit/s). This may depend on the exact protocol used (NFS-UDP/NFS-TCP/SMB/FTP) and the exact network hardware used. Generally, we do not see such file copying improvement (even when it takes place) as a very important thing in comparison with all the potential problems, so we do not recommend this unless you are really interested to experiment with it.
Note, the support for Gigabit is really broken in Sigma 8642 chips (could be either hardware limitations, or driver issue, or both, we do not know this for sure) and Sigma decided to not support it and according to the currently available information does not intend to support it in future. As soon as we understood this, we decided to focus on ensuring good network playback performance not depending on whether the network is 100Mbit or 1Gbit, and invested a lot of effort into optimizing and tuning the network playback functionality (took several months of work of experts in the development of high-performance network applications and also Linux kernel / Linux embedded programming experts). The result of this work was called "Dune Network Playback Accelerator".
However, it was decided to keep the support for Gigabit in the hardware of Dune 3.0 units and keep it in the firmware (in the form of "experimental support"), in order to not restrict the users (some of users may be interesting in improved file copying speed, if this works OK for them). It is also potentially possible that Sigma will improve/fix their driver support for Gigabit and things will improve in future; if this happens, Dune 3.0 users will already have Gigabit hardware in their units and thus will be able to benefit from this.
2. Dune Network Playback Accelerator is a set of advanced optimizations for Sigma SDK and for our own code implementing network playback functionality. These optimizations allow 8642 chip to much more quickly transfer the data from the network into A/V decoders of the chip, spending much less processing power on this, and also do this in a parallel with other required processing (such as processing of heavyweight menus). The result is that even the most high bitrate and heavyweight content should be played smoothly even on 100Mbit network, even when using SMB, at least in most/typical cases (unless there are specific issues with specific network configuration or network hardware). In our test lab, we've neer seen so far a content that could not be played smoothly via SMB/100Mbit, even the most problematic content (that could not be played on 1.0/2.0 units even when from local USB HDD) played smoothly on 3.0 even when using SMB/100Mbit.
So, for Dune 3.0 units, getting very high "Read Speed" in the built-in Dune read speed test is not as important, as it was for 1.0/2.0 units. For 1.0/2.0 units, it was needed to get at least 13-15MB/sec read speed to have good BD ISO playback performance; for 3.0 units, there is no such a need and even speeds provided by 100Mbit network are enough.
3. @Mart1001: "With SMB I get i/o errors when playing 1:1 bd rips from a bdmv folder." - do you use the latest beta firmware? This beta fw introduced some more optimizations for SMB (not realled needed for 3.0, implemented mostly to improve things for owners of 1.0/2.0 models), maybe they do not work properly for you. You can disable them via "Setup / System / Fast SMB access" setting and recheck.
Thanks, now I understand much more due to your clear explanation.
Yes, I use the latest beta. Before that one I didn't test SMB because NFS was better as many wrote here. I will test with fast SMB disabled.
How ever there are more having SMB problems:
neo2001 (also i/o errors)
Sparkss (file based playback problems with SMB)
BTW, just for the record I tested the other 1gb switch and got again as HDI_fw_dev explained the same behaviour. So I'm done testing :)

I have a DS-409+ connected to my Prime 3.0 (with initial f/w) at 100MBit eth and as far my tests are gone, I didnt experienced any problem playing .mkv or BD-Iso, no stuttering in audio or video.

Same here with a DS-509+ with NFS (TCP), Fast Ethernet 100MB/S is sufficient for all playbacks.
