Hi, for my DNS-320L LAN Link Speed, I only have the option of either 'Auto' or '100'.
Why can't I set it to 1000?

And how do I view if my computer has 1000Mbit connection?

Hi otog!

Your setup is correct, the cables may be OK for Gigabit Ethernet. Cat 5 UTP is the minimum needed (OK for shorter connections).
Cat 5e is a good choice.
(Choosing better quality instead of better price is often a good idea. I have CAT 7 in my house's wall cabeling - which is an overkill for GigE, CAT 6 terminals and CAT 5e cables between devices and the wall plugs).

Check this:
  • Does your computer show a 1000MBit connection (Windows: in the properties of network adapter)?
  • Is the NAS set to 1000 MBit?
    DNS-320L: Network Management --> LAN Setup --> Link Speed Settings:
    LAN Link Speed = 1000.

If these 2 checks are OK, but still slow transfer <10MByte/s, then test a direct connection following this:
Have a CAT 5e cable directly between your computer and NAS. Set in both a static IP address, e.g.: 192.168.0.1 for the PC and 192.168.0.2 for the NAS. Then try to copy files from your computer to a share on the NAS. Enter the NAS's IP Address in the file explorer to get access (\\192.168.0.2).

No idea, check if the router your NAS is connected to provides Gigabit ethernet. I can only assume that the NAS detects that the router only goes for 100MBit. But this is just a guess.
(btw.: also a weak / damaged cable can lead to this, because 100MBit uses only 2 wires while GBit all lines.)

Go to "Network and Sharing Center", then "Change Adapter Settings", right-click on your network adapter --> "status"
"Local Area Connection Status" shows the speed.

cheers.

Hi all!

For everybody scratching their heads about slow transfer speed:
This massively depends on the type of data.

Pls check my post regarding Transfer speed test for more details:
http://forums.dlink.com/index.php?topic=55773

Even with a fast GBit connection and good cabeling, it could happen that the average speed is as slow as 4MB/s just because of a large number of small files.

I'm having the same problems on my Mac.
I managed to create a "sparsebundle" on the NAS (<--- Google that!) , even though am not a tech-meister, and realized that, when transfering data between my Mac and the NAS using AFP (Apple File Protocol), it was much faster than any other way.
By default, SMB (Samba) protocol is used for file transfers, wich is mainly a pin in the neck for Mac users.
SMB is not a friendly protocol for Macs IMHO. (Believeme!)

I'm looking forward a new firmware that allows us, poor Mac users, avoid SMB conections to our NAS!!

In the meanwhile try creating a "sparsebundle" and allow AFP connection to it.
THAT ROCKS for backup puposes!!!

Hope that helps...

Guzzz

Hi All,
Got the same problem, and based on current changes on the setup I dont believe this is network related.

Laptop (Win7) directly connected to DNS320 (100Mb). Able to have 6,5Mbytes /sec transfer rate.
With 100Mbit it is supposed to be upto 12Mbytes/s.

These are the items I tried changing w/o any success.

- Tried 1Gig connection, still the same slow transfer to NAS
- Used a different laptop (WinXP) 100Mb, that has the same speed, 6,5Mbyte/sec
- Replaced HDD in NAS, also in the Laptop, no change.
- Laptops OS was reinstalled, same result
- Used different cables Cat6E, same result.
- Upgraded / downgraded NAS OS, same result

When I tested HDDs for transfer rate they can rock to much higher speed. All points to NAS, but not sure if I can change anything else. This is shame and annoying, as I 'd like to transfer 500GB data weekly, biweekly basis to do proper backup.

Appreciate any help, suggestion.

Hi,

Is Jumbo packet size enabled on your networkcards?

Have transfer rate 10 - 30 Mbytes depending on filesize.
