Vista Wireless Performance Questionnaire

You could try contacting support again. These kinds of issues can be difficult to resolve.

Have you tried a direct ethernet connection between the computer and the ReadyNas to see if that works fine? Or how about an ethernet connection into your router?

Does anybody know whether these problems still occur on Windows 7.
I have MSDN access and would be able to install Windows 7 Business on my machine. I acctually wanted to wait a little but if I get my XP-Style network speeds back I would risk ist. ;)

Yes, my upgrade (reinstall) from vista to windows 7 did not solve the issue :/

All -

Just wanted to report that after hours of tinkering I finally resolved my vista wireless problems. I had the same issue as everyone else: wired performance is great, but the NAS is basically unusable over wireless.

Here is my setup -
O/S: Vista SP2
Wirelss Router: Linksys WRT54G (the linksys router everyone and their mother owns)
Router Firmware: Latest as of 9/7/2009
ReadyNAS Model: Duo
ReadyNAS Firmware: 4.6.1

Solution: Set MTU size to 1460 on ReadyNAS Duo.

Yo-dah suggested changing the MTU to that on another board because it turns off burst mode or something, which is the default on the duo and NV+. That appears to be the problem here as well. Note that I tried MTUs of 1492 everywhere (laptop, duo, router) and it didn't help. I also changed the throttling for multimedia packets (or whatever that setting is) and it did no good. So I returned everything to default and tried the last suggestion I could find -- MTU on the DUO to 1460. It did the trick.

So if you have a WRT54G and the duo is unusable (it was fine if I plugged my laptop into my router) try setting the DUO's MTU to 1460. I wanted to get it posted in this sticky forum item so hopefully people will be able to find it easily and try it!

Good luck!

just set my MTU to 1460 now i cant get a connection to it :(

i have said it before an i will say it again "netgear sort it out will ya" this stupid.

i had the MTU set on the duo to 1492 and the wireless was sort of usable :? now i have added a netgear gs801t switch to the setup and now i am back to square one.

anyone got a suggestion

This tutorial fixed my problems. Set the MTU to 1430 on my Win7 laptop and get much better wireless performance to my ReadyNAS Duo. Left the MTU at 1500 on the ReadyNAS. I've gone from unusable to around 1MB/s transfer speeds for larger files, and video that is streaming perfectly.

Fantastic! Delighted with the find and the subsequent post from Dave / dbott67.

My two year old Buffalo Linkstation finally failed and I went in search of a replacement. I bought my ReadyNAS Duo 2 months ago and installed 2 * 1Tb drives from the approved compatible list. Initially I was very pleased, as things were working like a charm, hooked up to my Gigabit network, including a Netgear WNR854T router, a couple of Netgear GS105 switches and a GS108.
Then I tried to access the ReadyNAS from my Vista laptop. As others have reported, the data access times were chronic. I didn't bother running any timings as it was eminently clear that there was a serious fault. Wireless access from my XP laptop was good, so I tried two more Vista laptops (my kids) and a final laptop on which I've been running Windows 7 beta. With the exception of the XP laptop, each machine experienced serious performance issues retrieving a single photograph, an individual MP3 track or any simple file from the ReadyNAS.

Meanwhile I'd located this forum and this thread in particular. With other priorities, I'd put the wireless issues on the back burner, but occasionally dropped into the thread to see what new developments had arisen. I was delighted to read Dave's post, as none of the other things that I'd tried had any effect on the wireless performance. I carried out the intructions on my 1st Vista laptop and bingo! Everything worked properly. I went on to implement the changes in the two other Vista laptops and the Win7 laptop, successfully resolving the ReadyNAS performance issues with each one.

Much Kudos to the author for this fix.

Well I'm getting 0.5mb/s read and 1.5mb/s write over wireless (according to the iometer test). Not impresssed This is still much higher than before I changed the MTU on the laptop to 1430. Also tried making the Duo 1492 and that slowed both read and write further. Making the drive exempt from scanning by eset doesn't help. Not had time to run IOmeter on the XP machine yet. May try tonight.

Newbie question. Are the MTU settings arbitrary? Ie I see that 1430, 1460, 1492 and 1500 are all used, but is there any reason to stick to those values? (I know that 1500 and 1492 are internet standards, but will my normal wireless performance be noticably impaired by dropping from 1500 to 1430?).

Equally not run IOmeter when cabled to the router, although a file transfer showed that the rate dropped from 1mb to 20kb/s. Actually just thinking about that, it's odd that copying files reported a write rate of 1mb/s but IOmeter says 0.5.... I wonder if that's because IOmeter is using a 'v:' mapping as opposed to the file copy that we done using '192.186.0.8/media/'?

I was about to throw my 6m old Vista laptop out of the window. No usable connection to my ReadyNAS NV, while an old XP laptop could connect perfectly with very acceptable speeds. I thought I'd tried everyting, including changing the MTU to 1492 and 1460, but to no avail.

Using MTU of 1430, as suggested in above article, fixed ALL, again ALL, issues with Vista and ReadyNAS. Thank you again for this, but man, why should using your computer be such a pain in the butt....
