What is the best compatible Intel wireless network card (or any other for that matter) for R7-571-6858 ? I'm having difficulty finding reliable or clear information on this matter and if anyone could guide or steer me in that direction, I would greatly appreciate you help. Upgraded original card to the Intel 7260HMW PCI-E BT 4.0 and wondering how I could upgrade if possible. Bluetooth and wireless connection to displays or mirroring doesn't work and have read it is a problem common to this Acer model. I can connect For example, I can not Bluetooth to a speaker but phones will. I cannot mirror to any TV period. Phones will. I would much appreciate any advise, expertise, or where to go, and will respond to all with results.
