Please help in enabling wireless network card

Hello! I need a little help in enabling my wireless network card. The computer device manager says that the wireless network is working and that the drivers are all updated, and yet the network settings indicate that the wireless network card, a PCI Edimax EW-7128G, is disabled. I could not enable the network card either. I already tried using other network cards but still nothing changed. I am starting to think that this is the result of the recent replacement of the motherboard. Everything else used to work before except for the wireless network card. Do you think it has something to do with Windows 7? I would appreciate any insight you might offer. Thank you.
