Macbook Wifi - password not working

Macbook Pro 11.4 (2015) running the latest Manjaro Gnome stable.

I’ve been an Ubuntu user for 20 something years but thought I’d give Manjaro a try! Everything is wonderful except my WiFi doesn’t work. I’ve searched and tried all sorts of fixes without success. I hope somebody has a suggestion.

The issue is that my password is refused when connecting to my WiFi network.
Password triple checked - it’s correct.
Hardware worked days ago with Ubuntu Gnome. Hardware would appear to be fine.
Driver seems to be identified correctly by Manjaro.
Updates have been downloaded via tethering.

My gut feel is that this is not a driver issue and that something else is at play. Could well be wrong though! Any suggestions gratefully received.

So the module is loaded and the interface is active and up?

We can narrow it down further, but not without more information.

Could you paste your system info into a code block here?

It’s all the output frrom the command:

inxi -zv8

When pasting, In the rich text editor mode it’s called preformatted text.

Or enclosed in triple backticks in markdown editor mode: ```

Given the issue, and while we’re here, we may need the output of:

lspci -k

Provide the inxi, but provided it is not a driver problem and you can see the network, 2 things come to my mind:

How many networks with how many names do you have (by the way, what model is the router?). Some routers make separate networks for 2 and 5 ghz, but allow setting the same name, but also allow setting different passwords, which can lead to confusion. Personal experience.

The most probable cause: WPA2 vs. WPA3. Check the setting on the router. I think the WPA3 support is still limited in arch/manjaro, or at least this was the case with older kernels.

Apple uses Broadcom OEM wifi devices. I don’t know which driver is provided by Ubuntu or how they configure a connection on a Mac.

I suggest you look at Broadcom wireless - ArchWiki for troubleshooting the connection.

There is also a section Laptop/Apple - ArchWiki pointing to various models and their known quirks.

If you are the tinker type - like I am - you just have to know why and you have that tinkling urge to make it work - carry on - have fun - otherwise load it with Ubuntu 26.04 - then you have a working system - not Manjaro but at least it is working :slight_smile:

Interesting! I’m pretty certain the connection is WPA3! I’ll try this asap.

Hi @Pioden and welcome to the Manjaro Community! :vulcan_salute:

We are still lacking the requested system info, therefore it’s still a guessing game, so please provide output of:

inxi -zv8

Note that the output produced by this command is privacy-filtered.

Please also remember to use proper code formatting as this makes it much easier to read on the Forum:

[Mini How-To] format code or command output

Select and copy all the text in the Terminal window (minus the prompt, if you are using zsh).
Then paste the output in between two lines containing three backticks
```
or three tildes
~~~

Or:
Copy & paste, then highlight the pasted text and click the </> button at the top of the reply window (easier for smaller outputs).

Cheers! :wink:

First try booting with this kernel parameter:
brcmfmac.feature_disable=0x82000

The issue was a regression in wpa_supplicant, see here.

Alternatively, there are other drivers that work, I used to use this tutorial to switch between them.

Yes, WPA2 and 2.4GHz was the only way for my 2009 mbp.

Sorry about the delay - had to do some work! :frowning:

the output of inxi -zv8 is

Network:
  Device-1: Broadcom BCM43602 802.11ac Wireless LAN SoC vendor: Apple
    driver: brcmfmac v: kernel pcie: gen: 1 speed: 2.5 GT/s lanes: 1
    bus-ID: 03:00.0 chip-ID: 14e4:43ba class-ID: 0280
  IF: wlan0 state: down mac: <filter>
  IF-ID-1: enp0s20u1 state: unknown speed: -1 duplex: unknown mac: <filter>

    broadcast: <filter>
  IP v6: <filter> type: noprefixroute scope: link
  Info: services: NetworkManager, systemd-timesyncd, wpa_supplicant
  WAN IP: <filter>

and lspci -k is

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless LAN SoC (rev 01)
	Subsystem: Apple Inc. Device 0152
	Kernel driver in use: brcmfmac
	Kernel modules: brcmfmac

I think that means that the correct drive is loaded. Will try the wpasuplicant solution :slight_smile:

@Pioden Are you running a TP-Link router by any chance?

@6x12
Ladies and gentlemen we have a winner!!! Thanks a million 6x12. I think I’ll stick to the ‘standard’ drivers with the kernel parameter while tinker and explore Manjaro :slight_smile:

@DeLinuxCo
Vodafone branded fibre router - not sure what the underlying tech is. But happy days a here as the issue is now solved :slight_smile:

Good to hear, in my home network we have one AppleTV box and one MacBook that the wifi stops accepting the password, and we have to reboot the TP-Link Deco mesh system for them to work again. Just thought I would throw that out there :slight_smile:
