Then select "Apply Changes" and reboot to take effect

After reboot, post new TCP Analyzer to see if MTU changes

TCP settings are good. Upload speed is still low.

I would try scanning for possible malware with AVG antispyware, SpyBot and Ad-Aware 2007.

sorry for the delayed reply, my internet was not working very well for the past few days.

by the way, i scanned my pc for possible malware with nod32, SAS, Sohos Anti-rootkit, threatfire and Spybot today and everything is cleaned. i even do offline cleaning on my pc.

Here's the result after the sanned. Still very slow upload.
