xps

I am running ubuntu 11.10 32bit in my dell xps L502. Working good except few problems.

Blue tooth always turned on reboot,I would like to turn it off always.
Screen brightness is not saved.Every time I reboot, the screen goes back to full brightness.How to save that?
and the most important problem is internet speed through wi-fi is really very slow when operating on battery.the card is intel centrino Advanced-N 1030 with integrated blue tooth.

Any help will be appriciated... :)
