BCM94360NG Poor Bluetooth Range (Used Multiple Antennas)

Hi everyone,

Hoping for some help when its comes to having poor Bluetooth range when using the BCM94360NG card on my build:

  • CPU: AMD Ryzen 7 3700X 8-Core
  • GPU: Gigabyte Radeon RX 5700 XT
  • RAM: Corsair Vengeance RGB Pro 32GB DDR4 3200
  • Motherboard: Gigabyte X570 I AORUS Pro Wi-Fi
  • Storage: M.2 Samsung 970 EVO SSD 500GB (x2). One for Windows and one for macOS.
  • Audio Codec: Not sure where to locate.
  • Ethernet Card: Not sure where to locate.
  • Wifi/BT Card: M.2 BCM94360NG
  • BIOS Revision: F20
  • OpenCore 0.6.1 (Release)

Here are my Kexts (incase it's related): https://imgur.com/9Z9XDLp

I replaced the card that came installed in the Gigabyte X570 I with the M.2 BCM94360NG card that's supported out of the box. I did a little bit of research here and Google'ing the issue but I seem to be experiencing something unique — my build sees and connects to Bluetooth devices, however, they need to be really close to the antenna. I had read that the 'shark fin' antenna that came with the NZXT H1 was preppy bad so I decided to purchase two new ones off Amazon:

and

Neither of these made any difference what-so-ever when it comes to Bluetooth range. My devices can't be further than a few inches away without loosing connectivity. Wi-Fi works flawlessly (router is downstairs on the opposite side of the house). The only thing I can think of is that I got a faulty card, but again, it worked out of the box and detected Wi-Fi and Bluetooth — it's just shitty range. I wouldn't really care much but I'd really like to pair an XBOX controller to play some casual games — can't even recline on my chair because it unpairs if I'm a few inches away from the antenna (back to the 'shark fin'). I'll keep doing some research — just thought I'd ask someone smarter than me.

Any ideas? Thanks for your help in advance.
