Hi all,
I've found a possible solution for extremely slow download speeds.
A possible cause under Windows Vista, 7, 8 is TCP/IP version 6 and/or QoS enabled in your network adapter.
If you encounter a slow download, e.g. 10% of what you expected, then try the following:
- First of all, closing opened applications is recommended.
- Open Network Properties (Start > Network > Rightclick > Properties)
- Open "Adapter Settings" at the left side of the dialog
- Locate the adapter that you are currently connected with your Internet. In most cases this is the "Local Area Network" or "Wireless Network"
- Rightclick > Properties on the adapter
- Disable the checkboxes in the dialog for "QoS" and "Internet Protocol Version 6"
- Apply dialog with OK
- Rightclick > Properties on the adapter, then "Disable" (you will loose internet connection)
- Rightclick > Properties on the adapter, then "Enable" (you will soon be reconnected)
I don't use an english version, so some names may vary.
You can easily undo the steps again, just enable the checkboxes again.
Effects:
Before the increase, my Windows 7 setup (3 GB) download didn't finish within 15 hours.
After the increase it finished 7% of the whole download within few minutes.
Side effects:
Disabling TCP/IP version 6 will probably have no effect on > 95% of all computers.
Disabling QoS (quallity of service) may have effect on some computers (approx 10%) causing worse performance duriing realtime conversations such as Skype, video conferences etc.
I am a little bit of disappointed from Microsoft in using that Secure Download Manager. This is not the quality and experience that I know and expect from Microsoft for so many years. Nevertheless, special thanks to Microsoft for the great products.
