Netgear ReadyNAS Duo And Windows 7 Don’t Mix!

Update 04/01/2012: After many many months of trying to get this to work I ended up selling it on eBay. Worked fine for me using any Linux distribution but using Windows 7…forget it. Always had all sorts of trouble. I run a windows server box at home now and no issues.

Ok, so last November I went out and got myself a Netgear ReadyNAS Duo network attached storage (NAS) device. All in all its pretty nice, has very low power consumption and good performance…but when trying to browse the NAS using Windows 7 I’ve had all sorts of issues.

Now, Windows 7 introduced some new features to help improve network access by caching and perfetching network data differently to how it was done in Windows XP. Windows 7 may also have some improvements made to SAMBA and CIFS protocols that maybe the readynas doesn’t support? I’m not really sure but read/write performance using windows 7 to the readyNAS is really not that good, but the problem is random. Sometimes it’s problematic and others its fine.

It’s really strange. I’ve used different linux distributions which all play just fine with it, my iPad has no problems with it and our XBOX 360’s in the house can all stream music, photos and video from it no problem. It’s really just Windows 7 that doesn’t like it.

A small rant for today, maybe others out there have had similar problems with the ReadyNAS and Windows 7? If you have pls post a comment below and share your experiences and maybe even a solution to the problem. I’ve tried turning off the newer prefetching, etc in Windows 7 with no luck. Tried reducing the MTU of my Win7 box and the NAS below 1500 but still no luck.

Ah well, i’ll figure it out eventually.

  1. Thanks Allan, that’s a good idea. I’ve disabled ipv6. We’ll see how that goes. At least over the last 30 minutes it seems a little better, but still occasionally slow, even when browsing shares. Its very strange, don’t have these problems on my Windows XP boxes.

  2. Any update on this? I am having a similar problem. Whenever I try to watch a movie with XBMC it constantly stops to buffer. I am sure it is something to do with windows 7…

  3. Well, I am very surprised tpo hear this. I have been using mine with windows seven sense launch and have no issues at all. I love using the duo from windows7. I also use it with my mac, ipad, iphone, w7 netbook, xp work laptop, blu-ray player, ps3, squeezebox, network cameras, and other dlna devices in my home. I also perfrom backups to the duo with both the windows built in client and time machine, plus other software backup/sync applications. I have access to it through a vpn when i am away. It is definently not the fastest computer, but it is not supposed to be. It more than gets the job done for me and everyone I know who uses it.

    With that said, I would like to help you get it working the way it should. I do not work or any where related to netgear, just cannot stand when I have a problem and no one is there to help solve it. So I will put it out there for the next time I am in a jam myself. Contact me with any questions. You can also check the forums over at

    BTW, I did upgrade my ram to 1GB from the 256MB it came installed with. I also only use 7200 rpm+ hdd(s) with it. Finally I use a gigabit switch for my main mac and pc connections. Other devices are either hardwired on a 100lan connection and others are either on a wireless g and wireless N connection. Obviously, the better the connections, the fewer devices i have using it… This is to say that most of my connections are on a slower connection and they still perform as they should. I push all of my devices to the edge and I am constantly trying to get more out of them. I am a gadget monger, lol.

  4. thanks for your comment JA. That is good to hear at least that some people have been able to use the DUO and windows 7 no problem. I think my problems might be related to the wireless drivers or x64 OS or something. As a test I tried Windows 7 32-bit and it seems to work better with the DUO. Also have been thinking about wiring up my house with ethernet or getting a couple of those powerline AV adapters and run ethernet that way rather than relying on wifi.

  5. Hi Justin, old thread but I arrived here now so what the hell.
    I’m running my Duo with Win& 64bit and no problems at all. Have it connected to a Gigabit switch fed by a cable modem and Win7 desktop to the same switch. Everything works fine and can access it from outside/ inside my LAN fine, love it!

  6. I have the same problem with Windows 7 and ReadyNas NV+:
    Randomly, clicking on a subdirectory of the share takes 6-7 seconds.
    Opening a 1Meg PDF files takes 20 seconds then another 20 seconds before Acrobat responds.

    I get normal performance only by using *hardwire* connection.
    There must be a problem with the combination of wireless setup of Windows 7 and CIF or Samba protocol of ReadyNAS. In fact, my same wireless setup works fine with my old HP MediaVault NAS.

    My solution: If you can, use 100mb or better wired connection until the problem is fixed.

  7. I’ve tried Changing MTU suggested by Peo above. And it corrects the performance problem when using a wireless connection to ReadNas.

  8. I used my DUO successfully with windows XP, but had massive slowness issues on Vista 32-bit, Win 7 32-bit, and Win 7 64-bit over both wireless and wired networks. My MAX throughput was around 1MBps, but often only a couple hundred kilobits. It was faster (several times over) to download from the internet than copy from my NAS.

    I tried every how-to, every update, and every hack I could. I tried factory resets, MTU adjustments, firmware upgrades and downgrades. Ya know what worked? Selling the cursed thing on eBay. Good luck.

  9. When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I
    get three e-mails with the same comment. Is there any way you can remove people from
    that service? Thanks!
