Before I proceed, I would like to share one common tweak/hack/patch among torrent downloaders to boost the download speed. If you are a Windows XP SP 2 user, your TCP connections are limited to a maximum of 10. This might affect your download speed because it won't let you connect to as much peers as you want. However, you can fix this by download this patch. Some people reported that their antivirus detected the patch a Virus, but afraid not. By applying the patch you can set the maximum allowed connections to any number you want - between 50-100 is acceptable. Try this and you will see a significant change in the download speed. However, if you are an avid torrent downloader you might realized after installed the recent Windows update the download speed is decreased.
Recent Microsoft update for Windows XP SP2 user upgraded the *tcpip.sys version from 5.1.2600.3324 to 5.1.2600.3394 thus reverted the TCP connection to 0 which obviously killing the download speed drastically. My BitComet average download speed is from 20kbps-60kbps dropped drastically to 1kbps-12kbps. Initially, I assume it was due to the Internet connection problem but the situation still remains same for couple of days. I even tweak my WiFi router and changed the Internet IP address hoped the download speed back to normal. Somehow, I happened to check the settings in BitComet to look for any changes and I saw at the Current Half TCP Connection shows 'This TCPIP.SYS is cannot be modified' and the new half open limit is '0'. It is changed, I setup open limit more than 0 and Current Half TCP Connection shouldn't show such message. Besides that, BitComet have a tool to patch the tcpip.sys and when I ran the tool I was prompted an error message stating the tcpip.sys version cannot be modified.
After cracked my head for couple of minutes to look for an answer, I found out the tcpip.sys is upgraded because of the Windows update that I installed couple of days ago. As a result it is pointless to run the current patch as it is unable to downgrade tcpip.sys to previous version. So, the only way to fix this by removing the update and you can do that in two methods:
- Click on Start Menu>Programs>Accessories>System Tools>System Restore. Open System Restore restore your system to later date, to any date before you installed the Windows Update.
- Or, for an easier way click on Start Menu>Control Panel>Add or Remove Programs. After browse all the way to bottom and look for Security Update for Windows XP KB951748 then uninstall it. Restart your computer, if you already patched you will see previous setting or if you didn't you can run the patch now.
I uninstalled the update and now I enjoying the download speed that I had before.
