Can someone help me?
My downloads start at 20kb and will last about 5 minutes, then it will drop down to 1kb or sometimes to 0kb. What am I doing wrong?

Details:
Streamyx package - 1MB RM88/= per month
Router - ProLink H9200
Port Forwarding - TCP port#64321; UDP port#64323.
Set Half Open download to 25, patched to 256.
Limited Upload speed to 20, Download 120.

I checked my IP address, and it does not make a difference if I am using 218.x.x.x or 219.x.x.x..... problem persists.
