I've been playing Black Ops in the 360 and noticed something. When you enter into multiplayer from the main menu, you go into options and go into System Info, it says NAT TYPE: OPEN, and also BANDWIDTH: in Kbps. When hooked up to the 4500 it usually shows for BANDWIDTH a value between 550 - 700 Kbps, when hooked to the modem it shows a value of @ 2000 Kbps. I have followed all the guides to the letter with no change. What's going on? My specs are, connection is cable, modem is a Motorola SB5101, and the router has FW 1.01.
redmercury, what is your advertised connection speed of your ISP?
For xbox live/black ops the Kbps in the options menu is the speed/connection test that treyarch does to match you up with other players of similar pings and bandwidth. The test is performed right after you click on Multiplayer in the game menu. In MW2 and older COD games it would run this ping/bandwidth test every time before a match slowing down match making time.
The number you see is the upload speed of your connection to xbox live, I believe it will not show a value higher then 10,000 Kbps, aprox 10megs a sec. A number of 10000 Kbps almost guarantees you being host. Being host in most cases gives you host advantage by registering your hits quicker then the other plays, no lag because same server is taking place on your machine. This was the case till black ops., treyarch has not added host disadvantage by lagging the host by 20ms and averaging the host ping to the average of the other players.
This all being said, my ISP speed is 50meg down / 2 meg up; Rogers Canada, crap for gaming because upload speed is what matters for hosting. When I connect I get a Kbps of 1,500. I have played around with the 4500 game fuel settings and have noticed if I place a lower value in my rules lets say 500 Kbps I see the same value in the option menu in BlackOps. I have also been successful in getting a higher value 6,000 Kbps in BlackOps by starting a torrent up/download. I think this happens because Rogers ISP just launched something called speed boost which grabs more bandwidth for the first 10 megs of data. I believe they did this to stop all those calls customers make right after they do a speed test.
The 4500 router is a great router it just needs some tuning through game fuel settings. You should be able to get 2000 Kbps no problem. I think you should upgrade the firmware and set up the game fuel settings from scratch.
