Proof?

Okay this is what happened... Before I turned on my plug, I changed the port of my LAN wire (the wire that is connected to my CPU) to port 1. After changing, i had download speeds more than 100 times faster than usual, so i went to www.speedtest.net to test my internet speed, the download speed was 16 MB per second and upload speed was 0.46 MB per second. But my usual speed was 100KB per second, thats the speed i get even by downloading from microsoft or any other website, my speed will be limited to the max 100kbps, that was my usual speed. Now it has increased so much, does it charge more? And i have another problem too, for example, downloading from Megaupload, i hit the Download button, but the download window didnt pop up, and the loading bar was stucked at the same place for a very long time... Wonder why is my speed that fast and why is the 'Download' window appears so slowly... i tried other sites, downloading a video, the 'Download' window takes 5 minutes to pop up, then right after i clicked 'Save' , i was noticed that my download was completed, and the file was 10 MB....
