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.

Doesn't help :(11) Are you able to try another router? A couple users reported replacing current router/switch solved the problem.
I will try... - Did you try this: http://home.bott.ca/webserver/?p=226
The solution above is based on the kitz.co.uk site, but sets the wireless adapter on the Vista machine to 1430. - guys i have just found by changing from WEP to WPA2 and switching to the 5ghz range it has corrected all the speed issues i was having with the readynas duo all now runs at the full capabilty of the wireless connection after changing the MTU back to 1500 on the nas :D
just thought this may be worth posting :) - I just changed to a different wireless router and the issues were mostly resolved.
- Dell Laptop
Set Wireless MTU to 1430

Thank you so much for posting this. I just set up my first Win 7 machine (skipped Vista, ugh), and boy did it need the fix.
Much appreciated!- I am running a Dell 1745 Laptop using Windows 7 Home Premium (64bit). Have issues regardless of whether I use wireless or wired connection.

Will try to pick up a new router this week. But if it doesn't work. I'd really like some help here. And I am out of work, so I can't justify $75 for a tech support call that is probably not going to resolve my problem. - Since upgrading my network backbone from a Netgear FS526T 10/100 switch to a Netgear ProSafe GS116 16-port Gigabit Switch, wireless speeds on both the Vista Notebook (Atheros AR5007EG) and my Windows 7 Tablet (Intel Pro 2915ABG) to and from my ReadyNAS NV+ have gone to rock bottom. We're talking 15k a second or less speeds, with frequent dropouts. The Vista machine has been sat for half an hour already just trying to connect to the printer on the ReadyNAS. I'm not impressed one bit.
My router is a Netgear WGR614V9. Setting the MTU to 1430 on the wireless machines used to cure the problem, but not any more. I tried 1460 too and that made no difference. Help anyone? I'm using ALL Netgear networking gear in my network and getting lousy speeds from a Netgear branded product, that sucks!
Wireless speeds are faster than ever, but why is Wifi so difficult for the ReadyNAS? After all these years this problem STILL rears its head, COME ON NETGEAR! - Hi,
I'm new to a ReadyNas Duo. I was having constant trouble with loss of connection between Vista on my laptop and the Duo. I upgraded the wireless driver on my laptop and still had trouble, but the new driver had some diagnostics. I found that I was losing the connection because of a MIC Failure with the Duo, related to the TKIP security protocol. I changed the security protocol on my router to WPA2-AES, and since then I have not lost the connection when trying to copy files to the Duo. I'm so relieved now I just had to share this. Maybe it will help others. - All fixed thanks! :D
Change MTU on ReadyNAS & Vista Wireless Connection to 1470
Cheers
