Yea, that is pretty good but just remember if you check with your ISP you are only GUARANTEED a certain amount of bandwidth. As with any connection your bandwidth is shared (yes DSL owners, just like cable, dont believe the ads) so at any moment you can lose that 896kbps and drop to a normal 100kbps. I would go and check your upload speed when the problems start occuring, maybe have a network with 2 machines setup so you can jump on the other and check it right away. Dont just do one test, keep doing it over a few minutes to see what happens. Also might want to use Tracert to see if theres problems between you and your ISP or between you and other players that are having troubles.
Another thing you can do is if you are running a ded server and on Win2k/XP is use the Performance tab on Task Mgr to watch your machines performance and be sure theres nothing internal causing a prob. Good Luck!
