I've got an Acer 5570Z laptop. I had to pull it apart a while back because the power plug shorted out. This thing has a "power board" in it and was easily replaced. My problem is that ever since I got it up and running my network hasn't worked. Windows sees the card and says it's working properly but no network detection. I thought maybe it was bad so I ordered a new card and installed it. Same thing. Windows installed the drivers set the card up and said it's working properly. No network. Right now I'm using a USB adapter but I need to get the card working. Any suggestions?
