Isn't there some trick with disconnecting from the ISP several times in a row?
Can't remember the details. Google/Bing may help.
I find that the IP Profile adjusts itself over time. If it is wrong for you, and can do better than the current settings, then it will eventually improve. By eventually, I mean within days.
The connect/disconnect thing is a way of provoking a reset.
