Vista Wireless Performance Questionnaire

Dell Laptop
Set Wireless MTU to 1430
All problems gone

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.

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.

0) Updated to Windows Vista SP1? SP1 contains a number of network changes that improved overall throughput with the ReadyNAS.

N/A

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.

No effect. Though it did seem to speed up for about 5-10 minutes than went back to it's turtle self.

Changed it...

2) What model of Wireless Router and firmware is being used?

WRT54GS using Firmware v1.52.0

3) What Wireless Card model and firmware being used?

Wired connection still has problem

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.

100 Full Duplex

6) What's the throughput from Windows XP to ReadyNAS and Vista to ReadyNAS? Both Machines at or near same location?

Both machines are in close proximity.

7) Whats the throughput from Windows XP to Vista?

Does disabling firewall help? One user reported problem solved by disabling Symantec firewall.

No

9) Does uninstalling anti-virus help? One user reported problem solved by uninstalling CA anti-virus.

Nope, didn't have any installed. Nor any difference after installing AVG.

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.

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!
Change MTU on ReadyNAS & Vista Wireless Connection to 1470

Cheers

So it looks like im at the same point as most.
I have a very standard home network with 2 hardwired PC's (1 Vista and 1 XP) and 1 Vista Laptop on wireless.
Wireless network is running at 54Mb

All systems and internet run fine. I also have a shared network drives in both the hardwired PC's.
Accessing these from the laptop is great, very fast and on windows task manager in the networking tab shows on avaerage that when i access pic's and vids its about 16-18% of network utilization sometimes upto 22%.

When accessing the NAS i've never seen it get over 1%. Its completly unusable. Tried all the MTU setting and also made sure my wireless is on WPA2 AES.

I got this unit so that i can do away with the network drive and have everything in one place and then also a backup copy via the raid system. I had then also hoped to expand my Netgear units so we can access vids and pics on the TV and in the internet. Not sure now thats going to be my plan.

Why would this NAS not opperate as i according to the netgear sales pitch is should do..........Its getting very frustraighting.

If anyone can offer any help, advise or pointers that would be great.
Cheers B.

Are you getting this slow performance on both wireless and wired, or only on wireless?

Also, can you provide a few more details about your router/switch?

It would also be useful to check Frontview's network statistics, and confirm that the drives are completely resynced.

I'm not sure if you followed these instructions or not, but if you follow these instructions wireless performance should be back to expected levels: http://home.bott.ca/webserver/?p=226

Hi,

This is the only reference to MIC failures I can find on the forum so I figured I'd give it a "+1".

After having tackled a disconnection problem between my Vista wireless laptop and ReadyNAS Duo in the past, I was surprised to find that lowering the MTU and mapping shares by IP address did not fix a similar disconnection issue on my girlfriend's new Windows 7 laptop.

Investigating with Wireshark simply showed a TCP re-transmit at the point of failure, followed by several ARP requests to find the NAS, before eventually timing out. However, as above, updating the drivers of her wireless adapter (Intel Centrino Wireless-N 1030) also installed an event viewer that immediately reported a MIC failure during the next test. I switched my router to WPA2-PSK AES and (it would appear) the problem has been solved!
