Well, keep in mind that Internet providers like to fool you by throwing that big 6 Mbps download speed at you, when most people don't realize that 6 Mbps only translates into a mere 750 KB/s. There is a huge difference between MB and Mb, where MB stands for Megabyte, and Mb stands for Megabit. There are 8 bits in a byte. When it comes to Internet gaming, your ability to kill others really has nothing to do with your download speed, but relies solely on your upload speed. By searching your ISP, I found that you use DSL from Bell South, and your 6 Mbps plan also includes a mere 512 Kbps upload speed. That translates into 64 KB/s, which is only slightly better than dial-up, lol. All technical jargon aside, when you kill someone (or attempt to), that data has to be uploaded to the service. If you have a very slow upload speed, that data can't be sent quickly enough for the kill to appear on your screen, or anyone else's. Games that take place on Xbox LIVE rely on this data to determine who dies and who lives. For instance, if you and an enemy both started to shoot each other at the exact same time, if your enemy's data gets sent to the service much faster, he will always win because the service registered him as shooting at you, before it registered you as shooting at him. I hope this can be of some help to you.
