Hi everyone,does anybody have configured a direct connection between a PC with network card Intel 82566 DC 2 with Windows Vista and a Ready NAS NV+ ?After a few minutes of slow speed connecion (< 100 Mbit), the network interface ofmy Ready NAS NV+ blocks (non response to ping).I've simply configured a direct network connetcion as described here:http://www.readynas.com/kb/faq/boot/how_do_i_direct-connect_between_readynas_and_pc_or_macThere is a list of compatible gigabit network card adapters ?Thank you all, any help will be appreciated!Federico

Have you tried a known good cable?Have you had any other network connection problems with this NIC?How old is the NV+?What lights are lit on the NIC ports when you first start and are the still lit when the NAS goes off line?While the NIC on the MB can fail, the cable can cause problems, and the NIC on the NAS can also fail. While typically very reliable, none are perfect.

Dear PapaBear, thank you very much for your attention!I answer to your questions below!Have you tried a known good cable?I'm using the cable that comes with the NAS, is it reliable?If not, can you suggest me a known good cable?Have you had any other network connection problems with this NIC?I've never had problems with the nic of my PC, but I've never used it at 1 GB / s !How old is the NV+?The NV+ is pretty new, I've bought it in july, but not used it very much.What lights are lit on the NIC ports when you first start and are the still lit when the NAS goes off line?When the NIC is working there is a fixed yellow light and a blinking green light for network activity.As soon as it blocks again I tell you what it does when it's blocked.I tell you one more thing that I think is important: these are the network errors of my NIC:Errori di rete [Ethernet 1]Negoziazione automatica 7Pacchetti danneggiati 0Disconnetti 0Portante False 7Errori inattività 255Errori di collegamento 0Errori di ricezione 179Errori di simbolo 15Tag VLAN 0Ritrasmissioni TCP 23Ritrasmissioni TCP non recuperate 15And I ask you some more questions: what should be the approximate speed of file transfer with a GB direct connection?Can I use Jumbo frame with direct connection? Would a GB switch give more speed than a direct connection?Thank you very much in advance!

Though cables can get damaged, so if you have another ethernet cable it is worth a try. federico.vitali wrote:Errori di rete [Ethernet 1]Negoziazione automatica 7Pacchetti danneggiati 0Disconnetti 0Portante False 7Errori inattività 255Errori di collegamento 0Errori di ricezione 179Errori di simbolo 15Tag VLAN 0Ritrasmissioni TCP 23Ritrasmissioni TCP non recuperate 15The two Ritrasmissioni errors at the bottom are not too unusual, but everything else should be 0. I suggest that you try clearing the errors and do another test, and report the new error counts. Some of these errors might be due to disconnecting/reconnecting the ethernet or restarting the PC.federico.vitali wrote:what should be the approximate speed of file transfer with a GB direct connection?You should be seeing transfer speeds between 25-40 megabytes per second for large file transfers.

However, a good switch will not slow it down either. Most people would use a switch, and generally would only use a direct connection for troubleshooting. The switch allows multiple devices (PCs, media players, the NV+, etc) to connect with each other. It also allows them all to connect to the internet.

Thank you again!I've tried another cable I have (I don't know if it's certified for Gb connections).After having reset the error statistics and after a quite long RSYNC session (12 GB transferred) with no blocking of the device (hope will not block again!) these are the statistics:Negoziazione automatica 0Pacchetti danneggiati 0Disconnetti 0Portante False 0Errori inattività 0Errori di collegamento 0Errori di ricezione 9Errori di simbolo 9Tag VLAN 0Ritrasmissioni TCP 0Ritrasmissioni TCP non recuperate 0I'll buy a certified cable to see if the remaining errors will disappear.To test transfer speed I've made a long file transfer over a windows network share and the average transferspeed was between 12 and 13 MB/s, far below 25 / 40 MB/s declared. Is the Intel 82566DC-2 such a bad device ? Can you tell me a good and tested chipsetto buy a new NIC for my PC ?Thank you again, I've really appreciated your help, and (I hope, perhaps it's a bitearly to say definitively!) you solved me a really annoying problem !Federico

The cables that were shipped with all of my NAS units (3) were Cat5. This was not a real problem with my NV+ (first unit) but they would not support full speed with the higher speeds of my NVX units. Unfortunately, the cables that come with the NAS units are usually folded and creased, and that is not good for the cable either.The file transfer speeds I have generally seen on my NV+ with gigabit switch and gigabit NICs in my PCs, is around 25-30MB/s. When I first set it up, I was getting 10 to 12, but I was going through a 100Mb/s switch and the ports on my router are also 100Mb/s not 1000Mb/s (gigabit) so my transfer speed was 10-12MB/s.Using a good Cat5 cable may affect speed, but I would not think it would cause the errors you are seeing. When I upgraded to an ReadyNAS NVX (discontinued in favor of the Ultra line) I chose to upgrade the switch and cables as well and went with Cat6 cables. For full Gigabit speed you will need Cat5e or Cat6 cables. It should be printed on the cover over the wires. Are you sure the NIC in your PC is gigabit? I know some entry level PCs with AMD processors were still being sold with 100Mb/s NICs as late as two years ago. You may want to check the specs of your PC. Of course if you are getting above 12MB/s file transfer speed, you have a gigabit connection all the way since that is the theoretical max on 100Mb/s connection. But again, that would not cause your errors.

When it locks up again, you might try disconnecting the cable for a minute or so, and then reinsert it, and see if that avoids the reboot.

I am thinking you should open a support case with Netgear, and have them analyze the logs, etc. before you start buying network stuff. This lockup might be caused by something else (a failing disk or chassis) that is being provoked by the higher speed connection. Though of course you are still seeing some network issues (receive errors, symbols errors) which are not normal.

I am also thinking that if you do not have a current backup of your data that you should try to make one.

If you leave it at 100Mb/s, do you get blockage or any errors?

No blockage or errors if I leave it at 100Mb/s !

Thank you Stephen! Next time it blocks I'll try to disconnet for a minute !

I've already opened MANY case with Netgear Italy. I have this problem since I've bought the NAS (July 2011). They sent me a new RAM bank,
they told me that it was failing sometimes. It seemed to work, but I didn't stress the NAS too much in that period (two month ago).
When I started to use the NAS intensively the problem was still there.

Now they have suggested me to reinstall the firmware (?), I've tried, but of course nothing changes... Now they tell me to make a factory reset,
but I'm quite sure that this is a network problem...

This lockup might be caused by something else (a failing disk or chassis) that is being provoked by the higher speed connection. Though of course you are still seeing some network issues (receive errors, symbols errors) which are not normal.

That could be, of course ... But the device seems to be healthy when the NIC blocks (normal reboot pressing power button).
With a traffic analyzer I can't see answers from the NIC. If there is a faulty drive I can't understand why the NIC does not
respond to a simple ping !

I am also thinking that if you do not have a current backup of your data that you should try to make one.

I do have a backup, but I use the NAS for my photography works, I can't stay with only one copy of my works, It's too risky.

Today a friend of mine lent me his gigabit card, with another chipset. That will be the next step...

That test would be a good idea. It would be a change, and if it goes away, you have your culprit. It is unfortunate that sometimes we had to resolve network problems by the process of elimination, but at times it is easier to do.

Looking back over the thread in your initial post you asked if anyone had a direct connection between the Intel chip and the NV+. Does this mean you are running a direct connection when you are getting the lock up. If so, then you only have three possible culprits - the PC, the cable and the NAS. Once you have swapped out two of them, and the problem remains, then the culprit is the third one.
