What I did was insert the hardware id for these microsoft cards into an older version of the broadcom drivers, and at least for me it works perfect. I noticed a lot were looking for this driver, and I found some instructions to use the vista drivers from the broadcom site. Didn't work for me so I made these instead!
Just open device manger, right click your wifi card and choose update driver. Then just point it to the folder where you saved this and it should install, click install anyway if you get msg about can't verify vender, yada yada yada.
This should work with mn-7
