Re: Vista slow wifi LAN transfers

Tech-Archive recommends: Fix windows errors by optimizing your registry

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.

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

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.
