Vista Wireless Performance Questionnaire
With the amount of Vista issues on the forum, we are putting out a questionnaire here to get more information on the setups to get get a grasp of what is happening. Based on user feedback over the last several months, we've also updated the questionnaire with some possible solutions as well that you can easily try out.
0) Updated to Windows Vista SP1? SP1 contains a number of network changes that improved overall throughput with the ReadyNAS.
1) Tried changing MTU on ReadyNAS and laptop to 1492? Instructions on how to change Vista MTU at http://www.kitz.co.uk/adsl/vistaMTU.htm . A couple users had success keeping the ReadyNAS MTU at 1500 and switching Vista MTU to 1460.
2) What model of Wireless Router and firmware is being used?
3) What Wireless Card model and firmware being used?
4) What connection speed are you seeing for Wireless Adapter (i.e. 54 Mbps)?
5) What's the connection speed between ReadyNAS to Router (10/100/1000 Mbps) -- you can see this in FrontView's Network page.
6) What's the throughput from Windows XP to ReadyNAS and Vista to ReadyNAS? Both Machines at or near same location?
7) Whats the throughput from Windows XP to Vista?
8) Does disabling firewall help? One user reported problem solved by disabling Symantec firewall.
9) Does uninstalling anti-virus help? One user reported problem solved by uninstalling CA anti-virus.
10) Does enabling jumbo frames work? Several folks reported problem solved by enabling jumbo frames, and this also had the effect of speeding up wired transfers.
11) Are you able to try another router? A couple users reported replacing current router/switch solved the problem.

- Thanks for the tip, Jellen! It seems to be working for me so far!
- Glad it solved your problems too.
All credit goes to another user on this forum which supplied me with this tip. - Thanks for the tip Jellen (and "ohter user") !
On my Vista laptop I also suffered from very sloowww access to my ReadyNAS Duo through WAN. I solved it using your tip:
1. Determine my ideal MTU setting: http://www.dslreports.com/faq/5793
Ideal MTU turned out to be 1490 for my Vista laptop
2. Change MTU setting of my laptop with your link above (http://www.kitz.co.uk/adsl/vistaMTU.htm)
Result:
ReadyNAS Duo MTU: 1500
Vista Laptop MTU: 1490
==> No more issues accessing ReadyNAS
Only strange thing: if I determine my ideal MTU with the new setting it turns out to be 1480. Strange, it seems to decrease with the same amount I decreased my MTU setting. Does anybody understand this ?
For completeness some connection speeds:
WLAN (54 Mbps)
Laptop Vista --> ReadyNAS: 21 Mbps (after rebooting my entire network !)
Laptop Vista --> desktop XP: 10 Mbps
desktop XP --> ReadyNAS: 21 Mbps
LAN (100 Mbps):
Laptop Vista --> ReadyNAS: 100 Mbps - I've tried all the tips above and still haven't been able to get my performance working well at all. I did notice one thing...when accessing folders containing exe files, my Vista laptop (wireless) is horrrrrrrrible. Of course my vista desktop (wired) has no problems whatsoever. A folder full of mp3 files, both seem quite well.
Update: Disabling my Anti-Virus and firewall (as suggested by another poster that I hadn't believed) DID make a difference and made all file transfers snappy-fast from my vista laptop. I happen to be using Symantec Firewall and shall be disabling it in favor of the Windows Firewall as soon as I figure it out. The Symantec Anti-Virus by itself works fine without interfering with my file transfers. - Been happily using my Infrant ReadyNAS for a few years until I got a Vista laptop. Appallingly slow network performance (I'm talking dialup 4KB per second rates) have made it unusable, especially with small files. Larger files, once they get going increase up to around 2.5MB per second. Tried all the fixes in this thread, none of which made any difference. Have tried turning off differential compression. Also tried the following
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
Whilst I'm sure this is a Vista problem, Microsoft are the big fish out there. It's high time Netgear either fixed the firmware or wrote some sort of script/exe to apply some of these fixes automatically. - Aaargh this was infuriating! Thankfully we have an active community for this device, unlike other (cough cough c-s-o) devices I have bought.
Anyway, thanks to all who posted and just my two cents. I also have a notebook with a poor wireless connection to the ReadyNAS. Two solutions discussed here worked for me: setting MTU to 1492 on both my notebook and the NAS; better solution was turning on jumbo frames. This solved my performance woes and actually gave me a improved outcome.
I hope others are having similar luck. - Nope, there's now a big silver brick in my office with 3 hard drives in it.
- For what it's worth, all my problems disappeared after changing the router on my network.
I replaced the combo of Linksys WRT54GS + NetGear GigE switch with a D-Link DIR655, enabled jumbo frames (MTU jumped automatically) and now I get:
Vista wireless, read & write: 4.1MB/s (32 mbps)
XP wired, read & write: 17MB/s (136 mbps)
I have not yet tweaked journalling settings on the ReadyNAS, so might get some further boosts once I do that.gpvillamil wrote: 1) Has MTU been changed to 1492 and running Windows Vista SP1
Yes. Disabled Jumbo Frames on the NAS and set MTU to 1492. Also set MTU on the router to 1492.
2) Model of Wireless Router and Firmware used.
Linksys WRT54GS, v4.71.4
3) Wireless Card Model and Firmware
Intel 4965 AGN, 12.0.0.82
4) Connection Speed that you are seeing for Wireless Adapter. (54Mbps/24Mbps)
54 mbps
5) Connection Speed between ReadyNAS to Router (10/100/1000Mbps)
100 mbps
6) Throughput from Windows XP to ReadyNAS and Vista to ReadyNAS. Both Machines at or near same location. (Read/Write MB/sec)
Vista - read from ReadyNAS 1.3MB/sec
Vista - write to ReadyNAS 1.0MB/sec
XP - read from ReadyNAS 1.0MB/sec
XP - write to ReadyNAS 1.0MB/sec
The XP performance seems a lot slower than I remember.
7) Throughput from Windows XP to Vista (Read/Write MB/sec)
n/a don't have any XP shares visible to Vista
8) If MTU settings were changed to 1492 and SP1 is installed, Would like a Wireshark capture when transfering data from Vista to ReadyNAS
Notes: I have done all of the following:
1. disabled Vista's multimedia throttling via registry tweak.
2. disabled Vista auto-tuning (via netsh command)
3. disabled Vista firewall when on local network - FYI, I've updated the questionnaire based on the experiences of folks on this thread.
- Searching the Internet about Vista's generally slow network share access, this is all I did and wham, Vista is fast. Left my router/readynas settings alone.
Disabling Remote Differential Compression. To do this:
Open Control
Panel>Add Remove Programs>Turn off Windows features, uncheck Remote
Differential Compression.
Disable auto tuning:
From Command Promp, run as Administrator type: netsh int tcp set global autotuninglevel=disabled
