I came in to work today and, to my surprise, my wireless adapter doesn't work anymore. After a very painful 2 hour search for solutions in the internet, I'm here for help.

My wireless board is a D-Link DWA-525 (05:02.0 Network controller: Ralink corp. Device 3040) and I have tried installing drivers from source and using ndiswrapper with the Windows found on the CD that came with it. I'm running Ubuntu 12.04 with the 3.2.0-36-generic kernel.

Here's the relevant portions of outputs I can think of, please let me know if anything else is needed:

sudo lshw -C network

lsmod (Note that rt2800pci isn't loaded: I blacklisted it with sudo modprobe -b rt2800pci as a possible solution and couldn't get it to load again on startup. I can load it manually, though.)
