Judging by 'Google results' a common problem on DNS-323 is poor speed... my upload speed seems much lower than I would expect.
To eliminate one possible problem updated to f/w 1.1
Second common issues seems to be intermediate router throttling back the throughput ... re-cabled so it is directly connected to ADSL modem port. Now I appreciate this itself is a 4 port router, but my only access to Internet.
So Connection path is :
PC - Wired Ethernet direct to BT ADSL Router (100Mb)
Download speed - 10.2 Mbps
Upload speed - 11.2 Mbps
With seems quite slow for a 100Mb Ethernet connection.
No printer connected.
Is there anything I can do to improve this ?
-
With no information outlining what you're uploading to/downloading from, there can be no effective analysis of the problem - based on personal experience, I know a DNS-323 running into a 100mbps connection is capable of well over your posted results, so you'll need to look at the other end of the link rather than the DNS-323.
-
OK some more information... I have tested with 2 separate PC's .... both have 10/100Mb auto negotiation ports.
These are cabled to DSL Modem(Router) a BT Home Hub model.
Ethernet run is about 6m, on quality CAT5
Files are several Gb video files, so not multiple small files.
PC's are certainly capable of better transfer speed .......... can you suggest what I look at ?

Why are you connecting to the ADSL modem port?
Which model BT Home Hub do you have?
Have you tried using a good quality switch to make the connections rather than the Home Hub?
What are you actually trying to do, pull files from the internet or read them over a local lan?
-

Have you tested this or are you making an assumption?
A new, out of the box, DNS-323 with freshly formatted drives is capable of delivering read/write performance almost double that required to saturate a 100mbps Ethernet connection (obviously, you'll have to be using gigabit Ethernet to achieve this), and on 100 mbps it will, deliver many times over what you're reporting.
Yes - I am suggesting that you measure the throughput the PCs are capable of, as step one

"Why am I connecting to Modem port"
The Modem Router (BT Home Hub) provides 4 x Ethernet ports ... plugging NAS into that so it can be accessed by all PC's on network.
"Have you tested this or are you making an assumption?"
The figures I gave are actual test speeds on a single large video file.
How do I measure throughput PC's are capable of ? ..... These are reasonably HighSpec 64bit W7 PC's
I have 3 PC's and 1 Laptop all of them have 100/10 autoneogtiaon Ethernet cards ... I get simialr figures form all PC's
-
First up the modem port is intended for a BT Infinity modem and is not actually part of the ethernet router. The only way you could expect that to act as a router port is if you have custom firmware on the HomeHub and even then it would be limited by the hardware design.
Have you measured the speed you get when you connect the NAS to the single gigabit ethernet port and the test computer to one of the other ports? (assuming your HomeHub is one of the newer models)
Have you also tried a speed test using a gigabit switch in place of the HomeHub? Almost all models of the HomeHub have the router section running slower than advertised on the assumption that most people will be using wireless connections rather than wired.
-
You are misunderstanding me ... the back of my modem has 4 'yellow' Ethernet ports for my use .... as well as other ports for Infinity, etc.
I am plugged into a standard 'yellow Ethernet port'
I can plug NAS direct into PC ethernet and test ... I'll do that and report back ............. the throughput I'm getting does not change if I plug into an Ethernet switch (Dynamode SW800 ) ... which itself is plugged into one of the other 'yellow' ethernet sockets.
-
Sorry for the misunderstanding but the modem port on a HomeHub is the red/orange port which I assumed you were using because you said modem port.
When you say you tested with the switch was that :
NAS -----> Switch ------> Computer or
NAS ----> HomeHub -----> Switch -----> Computer or something similar?
My experience with the HomeHub has shown it to be the biggest bottleneck on a wired network. I setup a network for a friend using an 8 port gigabit switch to link the computers with the HomeHub linked to the switch as well. Doing it that way increased network throughput and allowed all computers good access to the internet.

Hi Memnon,
I wonder if the Unit is going bad? Without making any changes, unplug the DNS-323 and wait 30 seconds before plugging the unit back in. When turn on the unit.
Once the unit is fully up, copy a file to the unit and see how fast it is going. Make note of the speed.
About an hour later, do the same thing.
Report your findings to the group.
I record TV programs to my Laptop. I have done the above, because the speed of the unit starts out uploading fast at around 3 mbs per sec and afterwards, slows down to a crawl, reporting that the upload will take over 1 hour.

Connection was
NAS ----> Modem/Router <---- PC
File transfer speed on boot up ~10.8 MB/s
Now connected
NAS ----> Ethernet sw ----> Modem/Router<---- PC
File transfer speed ~11.2MB/s
So no difference.
Both of these align with previous speeds noted ..
I can't test NAS direct connect to PC as it does not support that type of connection has to be via router or switch.

Hi Memnon,
Not exactly what I was referring to, speed-wise.
I was talking to simply leave the connection normal and test my moving a file from the computer to the NAS unit. If you are using Windows 7, you can click on More Details, which tells you how long remaining before finished.
For me, it slowed down and I had to power off and power back on. This was Firmware 1.10. Today I dropped down to 1.09 Firmware.
-
It doesn't drop stays around 9.5 to 11 MB/s, which is pretty slow, makes backups betty long, and concerned what it will be like streaming video.
-
Hi Memnon,
If it stays steady, it is good, but what is the speed of your computer's adapter? 100 MB per second or 1 GB per second? Are you Wired or Wireless?
If you were kb/s, I would be concerned. But Mb/s is good.
-
Memnon, have you tried a speed test WITHOUT the HomeHub in the loop?
NAS <-------> Ethernet Switch <--------> PC.
-
OK ...Now connected
NAS ----> Ethernet sw <---- PC
File transfer speed ~11.2MB/s
So no change.
As to question of Ethernet cards .... it is the same of 3 separate PC's ... but for example one I am doing the test with is an ASUS P8Z77-V LE motherboard with Realtek 8111F GigE
Connected CAT5 to Dynamode SW80010 100MB Ethernet switch

Have you tried it?
IF you know what you're doing, you can connect any two computers to one another via their Ethernet ports and transfer data between them with just an Ethernet cable - no switch or router required.
The Ethernet port on the DNS-323 is "auto-mdix" - D-Link has made this so simple that if you take a brand new unit out of the box, stick a drive in it, plug one end of an Ethernet cable into it, plug the other end into a PC running Windows XP or later, turn them both on and run the D-Link easy setup utility, the utility will let you find, configure and use the DNS-323.
-
Yes I have tried it ... it does not work.
Maybe there are configurations changes that 'may' make it work, but it does not work with Auto-Discovery utility on CD
In fact I have a note from D-Link when I first bought it that advise that you must not connect direct to PC as it requires to be via Switch/Router or Hub in order to work.
Can't remember why but think it was something to do with DNS entry.
In any event it is not a configuration I could use in practise.

The DNS is not meant to be connected like that. On the other hand, if you need another Drive, simply buy an external Hard Drive and connect it via an USB Cable.
The DNS-323 is meant to be used for storage and a FTP Server, if set up for it.
One can simple use Explorer to copy and move files from the computer to any folder on the Hard Drives within the DNS-323.
-
appreciate its not supposed to be connected that way, and have no need or desire to do so. I was just responding to Fordem who was asking me if I had tried connecting that way.
-
IF you were to connect the DNS directly with out a router, your PC would need to be set up for static IP addressing...

Apparently you haven't been following the thread - which is an attempt to identify the cause of a "speed issue" - what better way to eliminate a router/modem/switch as a possible cause than to remove it altogether.
Whilst the DNS-323 was not meant to be used that way, it can be used that way, and in fact, my initial jumbo frame gigabit speed testing was done exactly like that because I wanted to determine whether the potential improvement warranted my buying a switch that supported jumbo frame.
-
IF you were to connect the DNS directly with out a router, your PC would need to be set up for static IP addressing...
First - I was very specific as to which versions of Windows could be used - XP or later - if configured for dynamic addressing and there is no DHCP server available, will use what is known as an APIPA address, a 169.254.x.x address - the exact address is of no relevance because the setup utility will discover the NAS using a network broadcast.
Second - once the NAS has been discovered, the utility allows you to set an ip address and then configure it - and since the NAS has a DHCP server, you can enable that, and continue to have your PC set for dynamic addressing.
-
Guys not wanting to stop debate ... but as I will never use NAS to PC direct, it would not seem that critical to argue about what could be made to work.
I would use the NAS either
NAS ---> Switch ---> Modem/Router <--- PC
OR
NAS ---> Modem/Router <--- PC
To confirm my PC's are W7 devices, and all connection are wired Ethernet.
I have dynamic DNS & IP adressing.

Hi fordem,
Testing or not, one can't tell if it is heat related or not, by testing out of the norm. And turning off and on and changing the configuration.

Hi Memnon,
Are you using the DNS-323 as a FTP Server as well?
-
A direct connection may not be the way you want to run the DNS-323, but it would have served my purpose, the key to diagnosing a problem is to simplify - to remove all but the necessary items - had you done that you would have known whether you should be focusing your investigation on the network or on the end point.
I'm not going to stick around where I'm not wanted, so I'll leave you to your debate, but before I go, there's something I want to show you ...
(http://img105.imageshack.us/img105/5527/dns323la4.jpg)
As you can see, the DNS-323 is capable of disk reads exceeding 27Mbyte/sec (roughly 250 mbit/sec) & writes in excess of 17Mbyte/sec (150 mbit/sec) - obviously you'll need to be running a gigabit network to achieve this sort of performance, and Memnon, this was done with a 32bit system at the other end.
When I say the DNS-323 is unlikely to be the cause of your speed issues, I'm 99% serious.
Oh - the details of the image can be found here. (http://forums.dlink.com/index.php?topic=3689.30)

Not currently, and don't have plans.

Anything else I can try .... only running at 11 MB/s seems very slow on a wired 100MB etherent connection

Hi Memnon,
That's your problem. Wired at 100 MB.
http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=200 (http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=200)
That is TigerDirect. Buy a Gigabyte Ethernet Card or an USB Hi Speed Adapter, if you don't know how to add a card, internally to the computer.
It is up to you. You don't have a Connection to support a higher speed.
And with a Gigabyte Connection, you will get a higher speed than from a 100 MB Connection, but you don't get a GigaByte Speed. You also need a Router that is a Gigabyte Router.
