I would like to comment that I did not spend a lot of time debugging this due to time constraints. Then again, something like this should probably work out of the box.
Upon installing the 13.04 beta2 (about 1-2 weeks ago, whatever release that was), I attempted to use the wifi on my MS surface pro. This was a fresh install, I re-formatted the partition of the hard drive that ubuntu sits on. I downloaded updates, etc, via a usb-ethernet interface.
The wifi widget in the top right hand corner shows 3 active instances of the wireless network interface for the marvell chip.

When switching the wireless functionality to ON, they seem to be competing with each other. All 3 of them show that they see the surrounding wifi networks but I can never actually get a connection. I get a prompt for the network password, I enter it, and then 1-2 seconds later I get another prompt, ad nauseum. I am not simply mis-typing the password. I remember seeing this behaviour before when I was trying to kluge together a working wifi driver with a 12.04 installation on my surface pro by grabbing the marvell driver packages from the 13.04 beta and manually implementing them. This suggests to me that there is something wrong with the driver for that particular chipset, rather than an installation error on my end. Though, I could be wrong.
Thanks
I am also seeing this issue on 13.04 final. I can't connect to open networks either. Any solutions?
