I'm surprised to see speeds around 11MB on a gigabit LAN and the NAS is also gigabit. I've been reading that when people take the DLink router out of the loop that there speeds get upwards around 48Mb or so. Or if they add in a non DLink switch put the equipment on that leg with the switch.
Are there some tweaks in the 825 that could help with the LAN speed for this NAS? Seems odd to have to buy a new router or add in a switch to do what this should be doing already. This is going to be an issue for streaming movies and especially HD via WiFi across the LAN.
I would also like to do my data backups to the NAS but when they hit around 60Gb it would take a long time to do a backup.
-
The best thing for NAS and is preferred is to add in a switch between the router and the NAS and other PCs.
Putting the NAS directly on a router will probably have inherent speed loss due to router processing and traffic management of any router. Why go through the router when doing file xfers when you can go from a PC thru a switch to the NAS.
ISP modem> router> switch< all connected devices to the switch.
I prefer to only connect necessary devices directly to the router, everything else is on a switch. Switches do the job well.

The DIR-825 is a router with a switch built in is why. It seems odd that the speed is an issue and you have to buy a separate switch. Other brands, apparently, are not having this issue based on what I'm reading.
Plus, if I had a Boxee Box I wanted to use WiFi which means it has to stream through the 825 anyway. Otherwise, to use this DLink product (825 and Boxee Box for that matter) I'm going to have to run a cable from the Boxee Box to the switch.
How do you like your Boxee Box? What kind of throughput you getting and how do you have it connected? I assume Ethernet to the switch?
-
Ya I agree that the switch on the router shouldn't be effected by the routers processing of the other traffic and features however it's integrated and I can only presume that how they implemented it could be a factor. I saw a post that others had recommended using an extra switch when using NAS.
My experience has been to use a switch specially having more than 4 devices. LOL.
Besides using a switch, they are not impeded by any other processing of traffic or features, just wide open traffic between devices.
Love the Boxxe man. Streaming has been seamless and video is awesome. I put movie files on the server and watch them from there. I haven't tried WiFi yet as it's all been wired. Since I got the 825 the other day I plan on trying Wireless and see.

Nice! I'd love to hear how the WiFi works out for you. Clearly you have wired your Boxee to the switch then. What brand and model of switch are you using and what have your data speeds been to/from your NAS?
Also, I've been using Harmony remotes for years and currently using the Harmony One with my main system. I see I'm going to need a IR adapter to get the Boxee to work with the Harmony One (to go from RF to IR).
-
I have a HP ProCurve 24 port Gb switch. I usually see 50-60 xfers. One other reason for using a extra switch is that if there is streaming or file xfers going on on the LAN, anyone using the WAN side wouldn't be affected, specially for gaming. Both of my xboxes are direct to the router. PCs and other stuff are connected to the switch.
I'll do some testing maybe tonite or next week. Just picked up a pair of B&W speakers for the new theater room yesterday. Trying to get it all sounding nicely.
Ya just preferred wired connection if I can implement it cleanly. Wireless is good and does well however not as good as wired. Will be interesting to see what Boxee does over WiFi with the 825. I'll post results.

Cool. Appreciate it. What kind of NAS you have?
Almost bought some B&Ws back in 2003. Went with Paradigms instead.
-
It's a server, PC that i set up to store files. ::)
Ya hear Paradigms before very nice. Didn't have the funds at the time. Just getting to where the wiring and such is being put in. Gotta plan it all out for the audio soon. Got the projector in house now. Can't wait to get it all complete. Walk away with a pair for $500 + tax yesterday, hehe.
-
Which model of B&Ws. Sounds like you're doing the house right.
-
Trying to, still go to finish the house. 704s. Hooked them up last night. OMG.
-
Nice! Almost got the 302s back in '03. Another reason I went with the Paradigms is that I wouldn't have to buy stands as the 302s needed them.
I'm in a townhouse. 1100sf on two floors. Nice place for me. My system has way too much juice for this space. When I first hooked it up I didn't have the sub adjusted yet. Watched a movie that had a huge explosion. Sent a shock wave through the six-plex my townhouse is in. LOL. I adjusted it immediately.
Router -> Switch... blah. Just to keep the topic. LOL
-
Okay...this sucks. Picked up a Trendnet TEG-S80g gigabit switch. Put my PC and NAS on the switch and my speeds are they same as if they were on the DIR-825. 10-11MB. Sucks...am I overlooking something simple? Or do I have to dump a bunch a money into a managed switch?
Seagate is of no help. As usual point fingers elsewhere and make recommendations of using some sort of network sniffer but cannot make a referral to any program due "liability issues". Said there is a program you can run on your network that will find the problem so you know what to fix. Never heard of an network app that does it for you like they described.
Apparently this NAS is just slow. I've tried:
- setting PC NIC to 9KB MTU Jumbo Frames
- speed & duplex set to 1Gb Full Duplex
- I'm using Cat 5e which should be just fine
- Transmit buffers are 128 (matter?)
- Receive butters are 512 (matter?)
There are several adanced settings for my RealTec PCIe GBE Family Controller. Not sure if there is somthing else that needs changing. The TrendNet can handle 9K Jumbo Frames. The 825 is supposed to as well and also the NAS.
-
THE PC NIC on board or card in a PCI slot?
-
This has occurred to me to. It is built onto the motherboard. RealTek.
I could try my laptop again to as I have not tested it with the NAS and switch. Or do you find that the Gb NICs on laptops aren't so great?
-
Ok, PCI slot would definately show a slow down unless it was PCI-e. Built in should be pretty good.
I would test it all out.
One think you can do is remove the router from the line. You can set up manual static IP addresses on each device then connect to the switch and test the speed.
Make sure all 3rd party security sw is disabled, norton and the like.
-
So you think the built in PCIe NIC is fine? Also, how does it help to use static IP addresses? Also, my cables are Cat 5e. I assume there is no need for Cat 6?
-
One test you can do is speedtest.net with your PC directly connected to the ISP modem. Should tell you that your PC NIC is good. If you don't see good speed then possibly the NIC isn't performing well.
Using static IP addresses on the router helps devices maintain there own addressing, the addresses don't change and effect options that you might have setup. If you don't use static IP addresses, it's possible that the IP might change thus effecting any options you set for those addresses, thus breaking the options or rules you set. Helps in troubleshooting and management of the router and your network.
Cat5e should perform well, however I do recommend CAT6 now that it's cheap and and easy upgrade.

-
So I assume you recommend setting static IPs in the router?
Ya, my speeds are 22Mbps/down and 4Mbps/up with or without the modem (DOCIS 3.0 - 1Gb port).
By the way bookmark Monoprice.com for cables. You can get killer prices on Cat6 that are 550Mhz. Plus, tone of audio/video cables and all sort of thing. Highly rated by may people on AV Forums and at AudioHolics. Do you think I'd see a worthwhile boost moving to Cat6?
-
Yes use the router for setting up IPs for all devices. What the routers job is. LOL.
Ya been there already It's cheap enough it makes sense too man. I did a upgrade, just patch cables for everything accept for 3 wires which are eventually going away for less than $30 bucks. I bought a 1000 ft roll for about $90 at the time. Thats going in the new addition when it gets ready. ;D
-
Hey...I just tried a direct ethernet connection between my laptop and NAS. I assigned a static IP to my laptop at the laptop and a static IP to the NAS (at the NAS) and got no better speeds. This sux as this is a good test to try. So, with all the testing I've done it seems I can connect to everything at gigabit speed but my actual data transfer is around 11MB.
I'm I just getting frustrated and going down the wrong path here or what?
-
Well you do realized that achieving actual GB speed is not possible. The GB speed is a physical connection speed between devices and getting a thru put at that speed is not possible at this time. Same thing with 5Ghz N mode WiFi 300Mps. Max speeds I see on my Mac Laptop is 10Mb for file xfers. These are just connection or link speeds, not file xfer speeds. However realistically you should be seeing upwards of 20-60Mbs at least.
However there are some factors that can contribute to xfer speeds:
OS, PC HW, HDD speeds, loaded 3rd party sw and such.
I know is sounds crazy that technically you should be throwing 900Mb speeds over a Gb line. Wouldn't that be nice. One day I guess.
-
I realize that connection speeds and actual transfer speeds are two different things. I'm seeing 11MB/s. So it is megabytes per second. But based on research it looks like people have been getting 40-60 "MB" unless they are stating it wrong. There's plenty of room for error and I'm not clear if it's the lingo of something in my network yet.
Using a quick conversion tool I'm told 11MB = 88Mb.
Here's an example with the NAS 110: http://www.smallnetbuilder.com/nas/nas-reviews/30982-new-to-the-charts-seagate-blackarmor-nas-110. I've seen higher on other sites. Here he's using "MB".
-
Ya I keep for getting that theres differences between MB and Mb. Possibily the OS is showing MB thus converting it to Mb for actual helps.
Was curious, how long is it taking to xfer a large file?
Some dull reading: :o

Well my main two concerns are:
- large data backups
- streaming movies and especially HD
Need the bandwidth.
-
I recommend the following layout:
ISP Modem> 825 router> external GB Switch<PCs/NAS and HD streaming devices connected to switch.
^Any non critical devices like gaming or phones or PCs can be connected directly to router if needed.
I have my 2 xboxes connected direct to router. All others are connected to switch.
Thus the switch would mostly elimiate any traffic or segregate traffic from other higher bandwidth traffic from lower band width traffic. So you could be watching HD or doing back ups while someone whos connected directly to the router shouldn't bother any devices connected on the switch.
-
After reading more I'm clear people are having success with 40-60MB range (not Mb).
As for my data transfer times. Right now my biggest issue is when I'm doing a full system backup. This is done every 5th backup and I think at 11MB/s it takes 5-6 hours which is nuts. It drops quite a bit even if I hit 25MB/s. That's why I want to get this worked out as to where the issue is.
I had thought about taking this switch back as it's performing the same as the DIR-825 for speeds. Maybe a little bit faster. But, since my bro bought it for me and it looks like I could use more ports anyway I think it's a keeper. Unless I find out that the Trendnet TEG-S80g is crap.
-
Well no real experience with TrendNet HW. I guess i'm a dye hard HP fan so I jump for what I could afford.

Seemed kinda extreme at the time, proved way valuable in the long run. Specially with new addition being completed hopefully this year, the networking is changing in a major way and this switch is going to be handy. ;D
-
Here's the end result:
* had Cat5 cables between the PC and router and the NAS and router, replaced with Cat5e (on hand)
* speeds between PCs (via the switch or the 825) are up to 55MB/s (yes MB)
* speed to this NAS is improved every so slightly. Maybe now 12-12.5MB/s from 11.5MB/s
Nice to know the router is doing is well as the switch. Wish the NAS were faster for large backups. However, since I do one full system state backup and then five incremental it's not such a big thing. I'm still using my secondary internal drive anyway for now yet.
I think the answer for the NAS is in the CPU and RAM. It has a 800Mhz Marvel CPU and 128Mb of RAM. I see the new Netgear ReadyNAS Plus and Pro units are running a dual core 1.6/8Ghz CPU and 1G of DDR3 RAM. Speeds on these according SmartNetBuilder are pushing 65-105MB/s depending on the model. These units don't come with HDDs.
Installed the Boxee Box and have tested it about as much as I can. Have done 1080P via WiFi with no issues from NAS to Boxee onto my plasma. Love to watch TED.com. Lots of stuff to choose from. Just need to get the Manta TR1 so I can use my Harmony One (IR) to control the Boxee Box (RF). Be nice if the Boxee were dual band but it only has 2.4Ghz. Interesting that we have the dual band routers but the equipment I'm seeing out there (Blu-rays, Boxee...etc.) seem to run on 2.4Ghz and not 5Ghz. However, shouldn't be an issue for me.
-
Wonder if CAT6 would do you better?
Sounds like you have been narrowing down the speed issue.
Glad the router and switch are proving to work well though.
I think the main problem with the dual band is that the 5Ghz freq is proven to be hard to use in the house hold. It's subject to interference from walls and doors and is not very good in this aspect due to it's high freq. All OEMs have this problem. 2.4Ghz has proven to be a good band for use. If they could find away to beef up the 5Ghz freq some how.
Been using my iPhone for controlling the Boxee, hehe. Been doing great here.

Good point about 5Ghz. For me I have a pretty clear shot between the router and devices.
I've wondered about the Cat6 cables and if that would help much. I will say there was barely any improvement between the Cat5 and the Cat5e when using the NAS. Big difference however for the PC. Like I was saying I think this NAS can do the job and it would be having to pay to get something with much better with a beefier CPU and RAM.
How does that work between your iPhone and the Boxee. I see the Boxee is uses RF for the remote so this must be what your iPhone sends out. When I get the RF adapter I believe I get all the basic functions like forward, rewind, pause..play. But the Qwerty keyboard functions are out for the Harmony One. That I don't think will be an issue. Will have to see. I haven't bought that adapter yet. The Manta TR1.
-
Not sure if you'll see any major differences between Cat5e and 6. It was cheap enough last year or the year before that I just bit the bullet and bought Cat 6 cables for everything I could. Spent under $30 bucks then also bought a 1000ft roll for about $95. Thats going into the new addition soon.
The iphone works great, it just has the buttons to move the cursor around and play and pause and stop. Works well. I think it works over the WiFi network that my iPhone is attached to the Boxee thats wired.
Whats this Manta TR1 about?
-
Since the Harmony One is IR and the Boxee Box is RF (so it can do all the command with QWERTY) you need something that can convert the commands. The Manta TR1 receives the commands from the Harmony One and then converts them for the Boxee Box. The Manta TR1 get plugged into a USB port on the back of the Boxee Box.

I see, nice. Might look into this one the theater room gets completed. ;)
-
Watch eBay to. Someone sold one recently for a lower price. That price at the site is decent and some times they run sales there. They did not long ago but that was before I had the Boxee Box.
What do you use your Boxee Box for? So far I've streamed TED.com, movies from my NAS, watched a few other things via a couple of Apps, played MP3s off my NAS, used the browser. I also like GrooveShark.com so I can use it now via the browser on the Boxee Box.
-
I will man.
I use Boxee to steam Netflix now, xbox was before. Stream BD from the server and play pandora. Whats GrooveShark like? any good?
-
I really like Grooveshark. One of the things they've done now is allow you to upgrade through doing surveys. The only thing that you have to deal with, on a PC anyway, is the ad strip on the far right side of the screen. There are two upgrade levels that you can earn points for doing surveys so you can work your way up the chain for free.
Anyway, what I've been doing is creating playlists. Then search for whatever you want to listen for. When you find it drag into your playlist and now it's always there. If you want you can buy the tune you want otherwise you always have access to it anyway. The two upgrade accounts give you access via your smartphone, etc., as well. I like it better because I can find things that pop into my head and I don't have to buy anything. It's like listening to the radio in a way however there are no ads to listen to and you get to hear what YOU want to hear when you want to hear it.

Edit: just transferred a file from my desktop to my NAS. About 1.36GB according to Win7. Transfer speed is showing at around ~19MB/s. Fastest I've seen yet. Hmm....
Starting to wonder about the MS nomenclature. File size was showing in GB not Gb. Maybe I'm getting myself confused now.
This appears accurate: "GB and MB stand for gigabyte and megabyte, respectively. They are measurements for memory capacity. It is a common misconception that 1 GB = 1000 MB. Actually, there are exactly 1024 MB (2 raised to the 10th power) in 1 GB, but because of the popularity of the Metric System, it was approximated to 1:1000 conversion which is easier to remember."
