@pastrychefSo, I've purchased a brand new (and different) PCI-E adapter, brand new MacBook BT/WiFi card (3 antennas this time) and used it to replace mine. Unfortunately, as I suspected, the BT issues are still happening. Now I am also seeing WiFi issues, where my packets are get lost once in a while, completely, while the OS claims the WiFi connection to the network is just fine.
I don't know why you are getting connection problems. What other devices around you are using 2.4GHz and 5GHz spectrum? I don't think there's any software that can help with this.
Remember, even USB 3 devices can cause interference with Bluetooth and 2.4GHz Wi-Fi. I had to deal with USB 3 interference on my old MacPro5,1 too. You can test both in Windows or Linux to make sure it's not a software issue.
