Vista - Unable to share large files across home wireless network

I have four computers at home, 2 desktop and 2 laptop, all running Vista HP.
One desktop is wired while the other 3 are wireless N. I am fairly certain
that I have all the permissions set properly since i can share smaller files
(<100MB) without a problem between any of the 4 computers. However, I have
recently tried to transfer files around 800MB with no success. "Calculating
time remaining" continues for several minutes without any data being
transferred and usually ends with a screen saying that I should check to be
sure I am connected to the network or that the resource on the other end is
unavailable. Wireless signal strength is good, so I am not sure whether the
problem is simply a Windows limitation or related to the Linksys equipment.
Any suggestions would be greatly appreciated

Also, the RWin AutoTuning issue may be relevant here.

Have a look at the above

Thanks for the response. My computer is already fully updated, so obviously
that isn't the issue. As far as autotuning, I attempted to disable it but
the commands listed in the link you provided all result in "Set global
command failed on IPv4 The requested operation requires elevation". The
resources you linked to make it sound like autotuning might be the problem,
so I'd like to figure out how to disable it in order to find out.

Thanks for the response. I am not really sure what part of that link you are
suggesting might be applicable. It appears to be just a basic setup guide
for all types of shares across a home network. As I stated in my problem, I
am able to share smaller files from any folder on any computer. The issue is
LARGE files that rarely even start transferring or only partially transfer
before process stops. I don't see anything in the setup guide that deals
with file size. Please let me know if I am missing something.

Does "fully updated" include the specific update mentioned? Very few computers
are always "fully updated".

Having the system set to automatically update will do so for security
related updates. Performance enhancements are often not included in the
automatic updates (often should only be performed if there is a related
problem). Do check the windows update site directly and the specific links
suggested by other posters. (be wary of any Microsoft suggested hardware
updates however)

Also you will need to elevate the command prompt before some operations.
Start orb
cmd
cmd.exe will appear at top under programs, right click it and select 'Run as
administrator'

I double checked, and the updates you mentioned ARE installed on all
machines. The only updates not installed are the optional Windows Live
programs. I sucessfully disabled autotuning on both computers and tested
another large file transfer (717MB). "Calculating time remaining" was
displayed for approximately 12 minutes before any data transfer was
indicated, and the entire file took about an hour to copy. It seems like a
long time, but I don't know. Wireless signal strenght is in the middle, so
maybe that is one factor. If you can think of anything else that might help
speed things up, that would be most appreciated.

Actually, I just tried a few more files of basically the same size and the
problem still exists. The actual data transfer still either stops after a
small portion is copied or never starts at all.

If you're using WiFi for the file transfers, trying Ethernet wouldn't be a bad
idea, at least for a baseline test. Then do a WiFi environment check - you
could have high signal strength, but with neighbours using the same channel,
you're going to have to share the channel.
