Vista slow wifi LAN transfers
A few months back I had to switch to Vista on a replacement laptop (Samsung
Q45). The performance is fine as is the RJ45 network connection, but I use
this laptop on WIFI, forced to 54 Mbps passing through a Netgear DGFV338
router to access the internet and other devices on my LAN.

The problem is when I try to retrieve data from my NAS (Netgear NV+) it
takes a rediculous amount of time to open up the smallest of files. As I
said before, when connected via RJ45 the performance is nominal (as with my
other XP PCs). I have no problem accessing the internet or mail servers, or
accessing the NAS from any other PC on the network.

I am running Norton Internet Security and have disabled this (just by
clicking the applications deactive options) and I see no change in
performance. I also disabled it in the system management console, and after
that I couldn't even access the NAS!

I have read most of the other posts on this issue and I have disabled the
IPV6 (in both WIFI & RJ45) as well as the 2 new mapping functionalities
listed under the network adaptor.

I have tried to disable autotuning level, but each time I try it is refused,
I think because it is trying to tell me I need higher priveleges (although I
am the admin!)

Below is a dump from ipconfig /all; I don't think there is anything unusual
here.

As you can probably imagine, a few months on from encountering this problem
it is getting frustrating and I am considering buying a long reel of cat.5
cable! If anyone has any ideas I would be grateful for any assistance.

Regards...

Re: Vista slow wifi LAN transfers
Hi
Without real numbers it is hard to relate to your complain.
While wireless is rated as 54Mb/sec. at best 802.11g would provide about
20Mb/sec.
The signal is further reduced with distance and noisy (electronic wise)
environment. It is not uncommon that the Wireless would yield low "Speed",
as low as 2Mb/sec.. while Internet related activities work Ok with 2Mb/sec.
LAN transfer would be slow.

Re: Vista slow wifi LAN transfers
You have to change the autotuning feature from an elevated command prompt.
Right click the command prompt icon and pick Run as administrator. There are
some other settings that may help.

Try all three, then try disabling them one at a time. You may not need all
three or they may not make any difference.

Re: Vista slow wifi LAN transfers
Hi Jack,

The network status is very good / excellent, in fact it is the same wireless
chipset as used in my old XP laptop on the network without the problems
identified previously. I did a file transfer (4Mbyte JPEG) to gain an
indication of the throughput and it came up at 3.74 kBytes / sec (<30 kbps),
values taken from the copy window. I am not sure how to measure the
data-rate for the internet, but this is acceptable.

Also, thanks Kerry, I made the 'netsh' mods after understanding how to
attack the problem, but unfortunately it made no difference.

Any other ideas?

Thanks

One other point, my 'recent' network documents are not updated in the START /
DOCUMENTS listing; not sure if this is related?

Gavin:

Just to be sure: are you upgraded to SP1? Some of these issues went
away with SP1 (but you are not alone with having Vista network speed
or other network issues...).

Re: Vista slow wifi LAN transfers
Hi Bob,

Yes the laptop is upto SP1... Is the problem I have described known? I can
see lots of references to the XP/VISTA visibility or both LAN/WAN but not
directly LAN only?

Thanks in advance, G

Re: Vista slow wifi LAN transfers
Try different drivers for the wireless NIC. Sometimes an older driver may
work better than the newest driver. Make sure both the router and the NAS
have the latest firmware. The right combination of hardware and drivers can
be hard to find. I had a similar problem with a laptop. Wireless was erratic
unless I used a very specific older driver. Whenever I updated to a newer
driver the problems would reoccur. Then I bought a new router. Suddenly it
didn't matter what driver I used, they all worked just as well. Consumer
routers cut many corners to meet a price point. Many older routers were made
to work with XP ignoring the recognised standards (RFCs). When Vista came
out using some of the newest, at the time, networking standards it broke a
lot of older routers.
