Broadcom BCM4360 - Wifi not working after initial install

Issues & Assistance Networking Support
1

Hi, I have installed garudalinux draganoized version gaming and KDE on an external hard drive using mac, installation was successful without any errors. After installation on Ethernet, I have followed Setup Assistant and Network Assistant to install related dependencies with full system update. Wifi and Bluetooth functional are Enabled, Bluetooth is able to scan near by devices, but I'm not able to find wifi, airplane mode, hotspot in menu under networks.

Also, I'm not able to find list of wifi's available. these features are working on the Linux bootable USB used to install. how to fix this?

I'm using Macbook Pro 2015, installed Garuda on external HDD. I have tried below methods but none worked and copied full system config.

Method-1: cloning git clone https://aur.archlinux.org/rtl8821ce-dkms-git.
When blacklisting current drivers, I'm loosing Ethernet.
Method-2: Clean Install again, not worked.
Method-3: installing different kernel, not worked.

please let me know if needed any other information. Thank you all guys.

Uninstall the broadcom-wl driver.

Restart.

Do not blacklist the brcmfmac kernel module, as the brcmfmac module is the driver you should be using.

This issue has been posted about more than once, please search thoroughly before posting.

This is a completely wrong driver for you, do not install this.

I will try uninstalling the driver and keep posted here. Do I need any other drivers that needs installation?

I searched for other wifi issues posted on the forum but I did not find anything similar. If there is a resolved thread with similar concern, can you share the link? I really appreciate it.

The driver the BCM4360 requires is included in the kernel. The reason the kernel driver is not loaded is because it conflicts with the proprietary wl driver. If you uninstall the wl driver the kernel driver should be automatically used.

Here’s a couple of similar solved threads regarding your adapter:

Be sure to check for a blacklist as detailed in the second thread.

I followed these two solutions mentioned above and they worked. Thank you for prompt response @tbg
