Title: bug report: Low-performance data transfers using the USB3 port
Post by: hydra3333 on July 12, 2014, 01:39:57 AM
Hello. Bug Reports:

DIR-880L. Australia. Firmware 1.00

1. Admin Password is not restored when a saved configuration is restored

When reloaded a saved configuration, the admin password is reset to blank.  I have to re-enter and save a new password.  
Test results:
- Tested twice with the same result.
- This is a bit of a security issue if you don't notice it ;)

2. Low-performance data transfers using the USB3 port with a 6 month old USB3 4Tb Seagate external hard drive

Copying a 1GB from the Router with attached USB3 4Tb hard drive -> to an i3820 PC connected by ethernet cable gives only 11-12MB/s.
USB 3 cable = 1m long.
Test results:
- The i3820 transfers files to and from another PC next to it (on the same router) at gigabit speeds.
- The the USB3 4Tb hard drive directly connected into the i3820 PC transfers at a higher rate, as expected.
- first time trying to write to the router's samba share from the i2830 I get the error message "There is a problem accessing \\xx.xx.xx.xx\Seagate_Expansion_3K0R1" ...
- after a power cycle of the router, I can copy from the i3820 -> to the router at 23MB/s but copying from the router to an SSD on the i3820 is only 11MB/s.
- a second attempt at copying from the i3820 to the router (the same file) ... 17MB/s ...
- repeated read and write twice more, consistent results: 19MBs write, but only 11MBs read.
- Unplugged the USB3 drive from the router and plugged it directly into the i3820's USB3 port using the same cable, and it averaged 160MBs copying a 1GB file from the USB3 drive -> to the i3820's SSD.
- Copied 54Gb of files (TV captures for offline viewing) from the PC next to the i3820, to the i3820 via ethernet and the router's routing
   ... it averaged 98MBs ... my old DIR-655 appeared "5% faster" with a slightly higher average
   ... the DIR-880L was a simple router swap-over so it is the same cabling etc)

PS waiting for the new AU firmware to be posted to the dlink.com.au website ;)

We have noticed this as this maybe a design security safety in case user forget the PW, reloading the config file still allows access with a blank PW while still preserving the custom configurations, I have asked about this.

Some of these rates maybe client side HW dependent upon what speeds are supported by the HW rather than the router HW. You need to detail more on what your PCs are seeing in comparison to what the router is doing.

I agree with Hydra on the admin password thing. Your custom password should be reinstated when you restore your configuration. If you don't know what your password was, you will just have to do a factory reset and create a new configuration from scratch.
Title: Re: Bug Reports
Post by: FurryNutz on July 12, 2014, 11:59:06 AM
I'll try to find out the behavior, however I personally would rather retain the configuration and have a blank PW after a restore should I some how forget the PW. You can always input a new PW after the restoration process has completed.  ;)

Thanks.

The combination of "same equipment used" and the data transfer speeds reported seem to indicate it's the DIR-880L router HW, since the other hardware and cabling is unchanged.

eg

I'm very open to suggestions on what to test differently, to provide more detail on what the PCs are seeing in comparison to what the router is doing.  

If the router supports ftp (I don't think it does) I'm happy to use filezilla to test transferring files back and forth. I'm using the SAMBA file shares and don't want to install more software (filezilla is already installed).

Post by: FurryNutz on July 12, 2014, 07:58:25 PM
Thanks for the details. Anything could be possible. Not sure if the behavior and the design of the router is to have the same performances as direct to PC. I personally have never found the same performances as direct connect with PCs. Routers have to process many things and in doing so, there maybe performance differences seen on USB with routers than with PCs.

You could test the newer FW.

:D not expecting same performance as direct-connect-to-PC, just > USB2 read speeds / "100Mbs" would be nice.

OK

You could test the newer FW.
Yes, I will try that in a few days (real life is intervening).

PS, no other network activity was occurring to interfere with the transfer test results.

When doing the USB speed testing, ensure that UPNP media and webfile access are disabled. Leave Samba enabled. That should help.

All DIR series routers do not transfer the password when saving/restoring configuration. This actually makes sense if you have an old configuration or multiple configurations and you rotate passwords. You will never know which config has what password and that is the last thing you need when you need to get the router online with screaming kids needing to finish their assignment. The lack of password when restoring a configuration is not a security issue. You need physical access to the router or at least the existing router admin password to gain access. Even with high end firewall, you'd need physical access to reset the box to log in and restore the configuration.

I am interested in this, too.

When I copy some files from my PC to the external HDD attached to the USB 3.0 port, I get about 25-30MB/s. This is not USB 3.0 speed. I'll try with the HDD plugged in the USB 2.0 connector tonight.

What kind of speeds do you see if you connect the USB drive to a PC?
Is the USB drive 3.0 supporting?

About 50MB/s, because the hdd in the PC is a little old. If I'll buy an SSD, I guess it will be a little more.

Yes, the external HDD is a Western Digital My Passport 3.0 (1TB), and it supports USB 3.0.

What is the speeds if you disable all USB router feature accept for SMB access? Disable DLNA, Web File Access and SharePort features and test again?

Be sure the let the router complete its drive content scan before testing xfer speeds.

Disable any PC security SW while testing.

Let us know what 2.0 results in...

2.0 results are about the same, ~25MB/s

If I disable everything, how can I copy files to the external HDD? I'm opening it by typing \\192.168.0.1 into Run.

In SharePort settings there is only UPnP Media Server, SAMBA and Web file access, as in the screenshot I previously attached.

With the settings as in the screenshot, the speed is the same as before, 25 MB/s, max 27.

I see SMB is a protocol, where do I find the settings for it?

Disable uPnP media and Web File access and test...
Also what kind of files are you using? Just curious.

Is the PC wireless or wired to the router?

Title: Re: bug report: Low-performance data transfers using the USB3 port

Still same results.

The PC is wired. I'm using large avi and mkv files.

You wouldn't have another USB drive to test with would you?

Post by: radubn on February 09, 2015, 10:59:52 AM
No. I have a 16GB USB stick, but the HDD is faster.

Anyway, since copying directly to the HDD connected to the computer gets >50MB/s, I'd say it has to do with the router.

Not a big problem now, but still...

What FW is currently loaded?
What happens if you go back to shipping version of FW? v1.00?

And I presume your PC HW is USB 3.0 supported as well?

I'll pass this along to the folks at D-Link for review. I'll post back to see if I get anything or some information.

Post by: radubn on February 09, 2015, 11:46:59 AM
FW 1.03WW, sent to me by somebody at dlink support, it is not available for download on the site. Shipping firmware was 1.01.

I've had some issues with the previous firmwares (wifi dropping on connected devices), so I am not willing to downgrade. All i can say is that on 1.01b09 and 1.02b13 the speeds were the same, so no improvement that I can notice.

My MB doesn't support native USB 3 native (Intel P35 chipset), but I have a PCI Express addon card, that I bought especially for the HDD, and that's what I use :)

Thanks for your time

Post by: radubn on February 09, 2015, 11:51:07 AM
I'm not really in a hurry with this.

If everything else works fine with the router, this slow speed is not a problem. It's better to copy at 25-30MB/s directly from the PC and read it on the TV through wifi, than removing the HDD from the TV, plugging in the PC, copying and bringing it back to the TV :p

I have an open ticket with this issue.

Also, in Linux, the external HDD drive plugged in the USB 3.0 port doesn't show up in the interface.

I have dual boot - Linux Mint 17 and Windows 7 x64; when I restarted and entered Windows, the HDD was showing up in the interface. I restarted again and in Linux wasn't visible.

Yes.

I can access the HDD though, in Linux, by typing smb://192.168.0.1 and entering user credentials.

Just it is not visible in the router interface.

Does anybody know how to "manually" re- index the content of the external HDD plugged into the usb port? I have several movie folders copied on it which I do not see on the TV through WiFi, even though they have the ".metadata" folder in them. If I physically connect the HDD to the TV I can see them just fine.

I've disconnected the HDD several times from the router, no luck.

I didn't restart the router though, I guess this can be done without a restart.

A restart of the router is needed with the drive connect will trigger the re-index.

I didn't want to restart the router, to see how much uptime I get with my firmware :)

22 days without major problems (two disconnects with a message like this "no network connection" while watching a movie on the TV streamed from the external USB HDD plugged in the router - the network was working, and after I tried again to launch the movie everything was OK).

After a restart of the router (with the HDD plugged in it) I waited for 10 minutes and then tried to access the HDD from the TV menu: I can still see some files which I deleted from the HDD two weeks ago. I disconnected and the connected the HDD to the router, same situation. I deleted all the .metadata and other hidden files on the router (maybe there is a directory tree somewhere which is still not updated), and no luck. No reindexing. Or not a successfull one, anyway.

So, my wish: a button in the interface to start reindexing the USB drive :p

What region are you located?

Can you test a 2nd drive, stick or USB that you can test with to see if files are updated or not? Start with something clean and empty.
How much data is on the HDD drive?

I don't have another drive for testing. There are almost 700GB of data, it's a 1TB drive (so about 250GB of free space remaining). Low chances of wiping it clean :)

You should think about investing in backup. Should something happen to that data...would be bad if something did.

Well if you happen upon a drive to test with, please try a clean drive and put some files on it...don't load it up. Do some removal and deletions and see what happens...if it seems to exhibit the same thing and it's not re-indexing fully or accurately, you'll need to contact your regional D-Link support office and let them know about the indexing feature that doesn't seem to be working.
