Keep losing connection to Time Capsule while copying large files from Windows Vista Business 64-bit: Error 0x80070079: The semaphore timeout period has expired

I keep getting "Error 0x80070079: The semaphore timeout period has expired" while trying to copy large (1GB+) files from my Windows Vista Business 64 bits laptop (this OS is running on a MacBook Pro using BootCamp) wirelessly connected to a Time Capsule. The wireless connection to the Time Capsule is interrupted when this error occurs and then I can re-establish the connection. The problem seems to only occur when I copy large files or when I copy many files at once.

Finally, it looks like a solution has been found. Have a look at Apple Discussions (Topic : WiFi dropped connection after 5 to 10 min when transferring data):

Notice that the symptoms are pretty much the same: "I am connecting to a Time Capsule and for some reason the connection resets when transferring large amounts of data".

Have a look at the solution that buknoy suggested:

1) Download the latest Broadcom Drivers from HP:

2) Do not run the driver installer, just right-click on the file you downloaded and extract it using 7-zip or winrar. Do not run the setup.exe file after extracting, it'll just install useless crap on your notebook.

3) Go to Device Manager and update the Broadcom Wireless N driver using the "have disk" option, pick "Broadcom 4321AG 802.11a/b/g/draft-n".

4) Restart your computer.

I applied this very procedure, but when I tried selecting "Broadcom 4321AG 802.11a/b/g/draft-n" the installer got stuck and my laptop stopped responding. I rebooted and tried again, this time I chose the driver "Broadcom 4322AG 802.11a/b/g/draft-n Wi-Fi Adapter". I installed it and rebooted the laptop. And...

The problem disappeared! :-)

I have applied the patch mentioned by strung. Unfortunately the problem persists. Thank you for suggestions, do you have any further ideas? (Interesting, why doesn't the patch work on my machine?)
If you Google your error message, you will find a large number of posts by people complaining of the same problem, with no apparent solution. Unfortunately, I don't think I can be of any further help.
You may want to repost the question in a Vista forum, as this seems to be a Vista, not a Time Machine, bug.

This question is already on the Vista forum. Hopefully someone will be able to help. This is still very much an open issue. Many thanks for your efforts, strung!
