Transferring over Wifi slows down the internet

I have two computers, a desktop and a laptop,
and a NAS, all connected to a 2wire router
from AT&T. The desktop and NAS are
connected through a wired connection, while
the laptop is connected via wifi.

I recently purchased this laptop, Sony Vaio
VGN-FW351J to replace my old Sony Vaio,
which did not have this problem. My old laptop
did not have Vista, only XP.

I use my desktop and NAS to backup from my
laptop, as well as to copy files from my
desktop to my laptop. These files are usually
very large and take time to copy.

Whenever I start a copy from desktop->laptop
or a backup from laptop->desktop, the copying
over wifi seems to use up so much wifi
bandwidth that I can no longer surf the
internet, am disconnected from gChat, etc, as
long as the copying continues. If I cancel the
copying or the copying finishes, then internet
access returns.

I am pretty familiar with computers, XP, and
routers, and have searched through all the
options on Vista and have googled to find a
solution to this problem, but have not found
anything that works yet.

I appreciate any help you may offer. Thanks!

I would look for an updated driver for your wirless NIC first, if that's not available, try:

Take a look at SG Vista TCP/IP Patch

I've used TCPOptimizer from them but it's not for Vista. It worked well.

Thank you for your suggestion. I tried enabling all the
settings, including the default, recommended, and other
settings, but either my problem remained or transfer speeds
slowed to nothing.

My wireless router and drivers were already updated to their
latest versions.

I appreciate any additional help people can offer. Thanks!

If you have a few extra dollars, you could take a chance on a USB wireless NIC or maybe you could borrow one.
