I've just purchased a dell l502x with an intel 6230 wifi. I've installed ubuntu 11.04 64 bit. It works, but when i use only the battery the connection slows down (my maximum download is 800kB and when my dell is unplugged it goes down to 200kB).
I think that is a sort of power saving, but how can i manage that?

Anybody knows something about that? Thank you!
