yes, it will.
In the intel proset utility there should be a page that shows signal strenght in decibels (dbm). Not sure what page, but if it's a "details" button then it's not updated in realtime, you have to close it/open it again. I don't think, it's there, but I'm too lazy to dig the laptops with that card out. Plus I have the new proset utility installed atm.
