Mac Pro 4,1>5,1 WI-FI Upgrade?
I want to upgrade the WI-FI on My Mac Pro 4,1>>5,1
There’s a free PCIe slot if needed,
I would prefer if it was PCIe with external antennas.
I believe you can use a better WiFi card in these older Mac Pro’s!
I believe it’s just the case of removing the ram/processor tray at the bottom then following this amazing guide linked below to connect it up correctly
Also here is a link to what you will need for the upgrade
The guide should walk you through installing step by step but here is another amazing video on installing it and what to expect with it
The WiFi card bit starts at roughy 3 mins in
Unfortunately I haven’t really heard of many (possibly any)people using external WiFi antennas on their Mac Pro’s as most people tend to go for wired Ethernet after considering a WiFi card upgrade on a Mac Pro as macs already have very good WiFi cards so if it’s speed your after you might want to look into that instead is it might even work out better
Hopefully this helps
Any questions please ask
Classic Mac Pro 5,1 (also 4,1 upgraded to 5,1) features only Wi-Fi 802.11n and Bluetooth 2.1. Here’re main reasons why you want to upgrade Wi-Fi to 802.11ac and Bluetooth to 4.0:
You get Continuity, Handoff and new AirDrop working natively
Wi-Fi 802.11ac is insanely fast, Bluetooth 4.0 is more reliable, secure and way quicker
macOS 10.15 Catalina no longer supports old BCM94322MC Wi-Fi card so Wi-Fi will not work there
1. Solder Bluetooth data cable to the mPCIe adapter
The original Bluetooth card will be removed because the BCM94360CD has both Bluetooth and Wi-Fi on board. D+ and D- connectors on the mPCIe adapter must be connected to the motherboard instead of the old Bluetooth card.
You will need THREE JST cables where you remove yellow and green wires (only black and red are used).
Connect them to each other so you have enough length for Bluetooth data cable:
Solder (or ask someone who has a soldering machine) D+ and D- contacts on the adapter to black and red wires correspondily (not quite neatly on the photo).
2. Remove CPU/RAM tray
Open your Mac Pro and remove the CPU/RAM tray.
With the tray removed your computer should look as on the photo below. Wi-Fi card is highlighted on the left and the small Bluetooth card on the right. Later we will be passing wires behind the area highlighted in the center.
3. Remove old Wi-Fi & Bluetooth cards
Unscrew two small screws holding the old AirPort Wifi card and disconnect 2 or 3 antennas by lightly pulling them towards you (depending on the model, one antenna can be unused and hidden below the card), remove the card by sliding it to the left.
Unscrew 1 screw holding the old Bluetooth card, disconnect data cable and gold antenna connector, remove the card by pulling it towards you, it’s slightly glued with adhesive.
4. Installing new Wi-Fi & Bluetooth card
The new card with adapter goes in the PCIe slot where your old Wifi card was. Connect three existing Wi-Fi antennas and one Bluetooth antenna extension cable to the card exactly as shown below:
Slide the card with all 4 antennas attached into the mPCIe adapter then slide the adapter into the mPCIe slot. Tighten the adapter in place with one of two screws holding the old card.
The loose end of our Bluetooth antenna extension cable should be connected to the existing Bluetooth antenna cable (disconnected previously from the old Bluetooth card).
The loose end of our Bluetooth data cable must be connected to the motherboard:
When possible use small pieces of tape to fix wires to ensure they stay securely connected and don’t move much.
