This item: New Apple Airport Extreme BCM94322MC Wireless WiFi Card for All Mac Pro MB988Z/A $37.81 Only 8 left in stock - order soon. Ships from and sold by TomNowak. There seem to be a popular problem with MacBook Pro Unibody where Airport stops working. I have found many blogs on line where people are very upset over the.

I am using 5g channel so it shouldn’t because of usb and 2.4g signal interference. I tried another BCM94360CD card and see same issue.

Wifi and Bluetooth works except when plugging usb 3.0 drive and then wifi starts to reconnecting. I tried BCM943602CDP card and Bluetooth becomes 4.2 but wifi still has this problem. I tried Catalina install USB and the install program cannot connect to wifi with same problem. Mojave install program has same issue. I tried reset smc and nvram and doesn’t help. Bootrom firmware is 137.0.0.0 the newest.

I tried Ubuntu live usb and seems doesn’t have this kind of problem. Seems like Mac OS can only work with original card but Linux can work with other cards. Really strange. Please help if you have some hints.

Is this a good question?

Airport Card For Mac Pro 4.1

If you got the correct board which offers: WiFi 802.11ac / Bluetooth 4.0 (Apple P/N 661-7552) Your symptoms don't make sense!

Let's backup here I'm assuming your original board failed, maybe we are looking for a different problem.

I need to replace old card with a new one. My new one is also BCM94360CD but doesn't work. You mentioned I should use BCM94360CD with Apple P/N 661-7552. How to know Apple P/N for one card? I cannot find such number on my card.

Lets refocus - What drove you into replacing the AirPort board in the first place?

@danj My current card has bluetooth 4.0, which doesn't work with my Sony headphone. I tried to install BCM943602CDP. It works with my Sony headphone, but has this usb 3.0 problem. I also tried BCM94360CD bought from eBay and has usb 3.0 problem too. I guess this is an OS problem since Linux works well with my BCM043602CDP card.

yes!! it sure can. I know because I've put one in before in another mac pro-and it's....tricky...

If you hold down the option key, Dave, and click on the wifi icon at the top of your screen, just past the bluetooth icon

and before the eject icon, it'll tell you what your signal strength is, what frequency, what kind, and a bunch of stuff that might be useful. also, on some mac pro's, the bluetooth wire is connected wrong, changing it to wire 2 might help out...

there are various things you can try, Dave---replacing the airport card is helpful, but it's tricky,. the screws are small, so a magnetized screwdriver is helpful, and the antenna connections are teeny-tiny, but it can be done.... you can buy an 802.11ac wifi card that'll work in your mac pro. you may be able to use a more generic card with the appropriate adapter, but this is mere rumor. -you may also be able to fit an antenna extention to the card and out the back of your Mac pro which might help things... i don't know what your router is capable of, though. You can also use a couple of AirPorts to extend the wifi network instead of just depending on one for wifi. You can also get a plug in wifi range booster which may be useful.....
