Hi everyone, I have become extremely annoyed by the signal quality of the built-in Airport extreme card of my MacPro3,1 (early 2008, 2x quad 2.8 GHz, 8GB RAM, ATI Radeon HD 4870, OS X Mavericks, 3 HDDs). It's really slow and keeps loosing the connection again and again. So I was looking into some alternatives. My wife won't allow ethernet cables in the house, so I was thinking of a PCIe wifi card. But apparently, there are not so many native Mac-compatible options? I read on some hackintosh-forums that the D-Link DWA-556 will be recognized as a native Airport Extreme card, but I seem to be unable to find any confirmation from someone actually putting the card in a "real" Mac Pro. So I was hoping that someone here can confirm or deny that it works? Alternatively, can anyone comment on PLC (powerline) if that's a viable option? I was checking into the Netgear POWERLINE AV+ 500 NANO SET (XAVB5601), but was kind of worried if this will work well in my 80 years old house? Thanks!
