Same issue here, I have an Acer Aspire M5-581T, Win 8.1 x64. Clean install. Updated all op system files, all drivers, and installed and update all the BT drivers. Still a no go. I can get either the BT or the Wifi to work, but not both. I have been looking around for a week and nothing seems to work. I sent an e-mail to Intel support, but I am thinking of just returning the card. Any ideas before I do?
Thank you
