Hey all,


Merry Christmas! Guys I'm getting read speeds only 5-6 MB/s on a Dune using SMB from a PC with choppy playback etc...often it's fine and then it goes to ****. Moved house so now have a new Verizon router which may be the culprit, its a D-Link DSL-2750B.


Any ideas? Settings on the router etc?


Cheers in advance for the help.

5-6 MB/sec is approximately 40-48 Mb/sec which is just barely adequate for BD playback with HD audio. Sounds like you may have some network issue, or competing traffic. Best you can expect from the NIC in the Dune is 7-9 MB/sec. If your network is not Gigabit, you might consider an upgrade to eliminate issues with competing traffic. It doesn't look like that router is Gigabit capable. If you're using wireless, that's the problem right there and you need to hard wire it.

It is hardwired, the problem is off and on,sometimes a BR .ISO will be fine, other times it will stutter and be a mess. restarting the router, PC and Dune will sometimes fix it.


Just did another read test and got 7.7


Any steps I could take on the router so as to avoid competing traffic? Router settings?

I assume that's a Verizon-provided router, do they have any support forums where you could ask about settings? You'll just have to get in the router interface and see what's offered. There may be settings that prioritize streaming media. But a decent Gigabit router with gigabit ports on your media server/PC would be a big help. Might be something running on the PC that's creating traffic too.

I'm not great with networking admittedly so bear with me! But buying something like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16833120655


plugging the the Verizon router into it to share the internet connection and plugging all other devices into the switch and not the V router is the right way to go?

If you're buying new hardware, just get a better modem/router and lose the D-Link. If its a leased modem, you could ask them if they have a newer/better model with Gigabit support. I'm not promising you that a Gigabit router will solve your issues, since the PC might also be the bottleneck. Swapping cables is also a cheap and easy step. Also, if you're using the USB port on the modem, stop it.

Thanks for the help rdgrimes....one issue I've read about the Oppo is that it works better in half-duplex mode. Maybe that will also help

I meant Dune H1!

The Dune should work fine with default settings, I really think you're chasing an issue either with the router or in the source of the media itself.

If its a leased modem, this is easy - just tell them it sucks and you want a newer one with Gigabit support.

Dune has fast ethernet interface, so all the advice about switching to gigabit router/switch is nonsense. It won't help (and many report it may make things worse). It has the "experimental" gigabit setting, but that's rubbish and almost guarantees to cause playback issues.


The read speed is a function of:


1. Dune settings

2. Physical network including switches/routers along the path

3. File server and it's configuration


I run a Linux server and w/Samba I never got stutter free playback. Solution was switching to NFS over UDP, disabling 'Fast disk access' and enabling 'Blu-ray playback/bitstream improvements'. Disabling 'Fast disk access' was crucial - I get solid 12MB/s and nary a stutter, before it would dip to 10-11 MB/s and while theoretically plenty for blu-ray it was stuttering somewhat frequently.


Others get fine results with Windows servers so YMMV.

Ah, I'm only getting 8.2MB/s max using SMB from a PC and it can dip to 5MB/s...mind if I ask what's the best (and easiest for us non-networking guru types) and easiest setup for NFS on Vista?


Thanks for your help...

IO contention on the server. I know from experience if my linux box goes into a heavy io usage on the drive with my ISOs that playback suffers. nothing to do with network.

Just switched over to NFS using HaneWin and still the same....looks like I need to try a different router or card in the PC?
