In Windows 7, https-uploads stop network - solution: turn off task offloading!

(nu blir det en post om dataproblem, på engelska dessutom)

So, we have had this problem with not being able to upload files from our Windows 7 machine (64-bit). On google, facebook, flickr, picasa, etc, whenever we have tried to upload something or make an attachment it has crashed the network. Our solution has been to troubleshoot the network, and after a while it starts working again. But not the uploads...

Until today, when I found the solution. - yes, it's in French (!), but it works!

This is how to fix the "Uploading to Gmail using https makes network stop working" problem:

1. Open Control Panel
2. Network and Sharing Center
3. Change adapter settings (on the left)
4. Right-click and select Properties for network card (mine was "Atheros L1 Gigabit ...")
5. Configure ... (button)
6. Advanced (tab)
7. Select "Task Offload" from list
8. Set the value to "Off"

This solved our problems. And it was not easy to find the answer to this one using google - seems it is a rare problem and most forum posts didn't mention the solution.
