I've had my DNS-323 for about a year, connected with cat5 to a DI-524 router.
My Win2000, XP home and XP pro computers are all connected to the router, and accesses the 323 without any problems, so both the 323 and 524 works fine.
But my Vista Home Premium has been a real pain since I bought it, after accessing the 323 for a while
it disconnects the Network adapter and claims that there is a problem with the router. All other computers work ok using the router and 323, but Vista closes the network adapter to both 323 and to WAN.

After requesteing status/"diagnose network" in Vista when this happens it usually presents the "there is a problem with your router" dialog which also contains the "reset Network adapter" option. After reset it works ok for a while again.
This happens whenever I do a copy from/to DNS323 of some 100Mb or more of files, sometimes it handles upto 3Gbyte, sometimes it dies after 10Mbyte. It also happens after a while when playing a slideshow from it so it seems to be related to number of bytes transferred somehow.

I've looked for a solution in forums the last 10 months. Using the NAS as a backupdisk is just not possible. When using Vista for heavy transfer to/from internet without involving the 323 it works without any problem.
I use 323 firmware 1.06,  PNPX-102 driver in Vista and the Network card is a NVIDIA nforce 10/100.
All available patches/updates to Vista to this date are installed.
I've tried to disable auto-tuning with "netsh interface tcp set global autotuninglevel=disabled",
and changed NetworkAdapter config to speed/duplex settings= fixed value instead of autonegotiate,
changed Priority & VLAN settings from priority enabled to disabled. Nothing works.

Is there anything else I could try before erasing Vista with a Linux distribution ?

Buy a simple PCI network card and use this.
Disable the onboard Nvidia NIC.

What would you consider as heavy transfer to & from the internet?  Most internet connections are limited in bandwidth when compared to a local network connection.

Have you tried transferring data to/from the Vista machine from/to one of the other Windows systems?  Does it fail there also or does it fail only with the DNS-323?

My suspicion is that you have a network infrastructure flaw - possibly the cable - that does not become a problem until the data rates climb above a certain level.

I've got a 100Mbit/s uplink and 10Mbit downlink to internet through cable and I've uploaded 1 to 1.5 Gbyte kits of data to US (from Sweden), and downloaded 500Mb kits of software distributions numerous times without any problems, but the transfer speed over the net probably wasn't that high.

I haven't tried heavy internal network traffic before since my NAS were supposed to get rid of the filesharing between machines, so I now tried to push data to the Vista machine from my XP using windows filesharing as you suggested - and the Vista network adapter shut down after 1.6 Bgyte transferred.

Now I at least know that the DNS-323 driver for Vista not is responsible.
Its either the network card, the cable, or possibly some obscure Vista settings thats causing the problem.
Thanks

I hate to argue - after all, what do I know about your internet connection - but - those figures just don't look right.  Yes, they are high, but I've heard of some countries with wickedfast connections, and you might be lucky enough to live in one - more to the point - you're the first person I've heard of with an uplink that's faster than their downlink - most unusual for a residential connection.

Anyway - the purpose of the exercise was to determine whether or not the problem was unique to the DNS-323 and we have successfully done that - and you have already identified the suspects, so why not start by swapping the ethernet cable leading to the Vista system and then proceed from there?

An update.
DNS-323 is not causing this, however there may be folks out there stumbling into the problem using DNS-323 from Vista just as I did.
It wasn't the cable, and all expansionslots are occupied so I couldn't plug in another network card.

I tried some more Vista settings with some of the speed/duplex settings not tested before on the network adapter. Changing the speed/duplex settings from autonegotiate to "Autoneg for 100HD" made it work.
I've tried the "fixed 100 Full duplex", and even "10 Full duplex" - but they made no change.
With "Autoneg 100 Half Duplex" I've succeded to copy 11Gbyte with 3400 files from DNS-323. I've never ever succeded with more then 3Gbyte before, so it seems to work now.

The change made the copy speed from the 323 drop from 10Mb/sec to 8Mb/sec.
And using a official test-utility of my internet connection performance, my internet connection speed dropped from around 94Mbit/s down/15 up to around 64 down/15 up (yes, my downlink is faster then my uplink - my fingers didn't write what I meant in my last posting).
Its annoying not to be able to use the full internet capacity I'm paying for, but using Vista it seems that I'm forced to it.
