GNU/Linux CentOS Stream 9 Installing Broadcom-wl Driver Guide

Hi! The Tutorial shows you Step-by-Step How to Install Broadcom Wl Wi-Fi/Bluetooth Driver in CentOS Stream 9 GNU/Linux.

And Broadcom Wireless Cards for CentOS 9 needs Proprietary Software (called “Firmware”) that Runs on the Wireless Chip itself to Work Properly.

Especially relevant: we provide here to Source Code Setup cause this Driver currently is Not in any EL Repository.

So this Guide is valid also for all the others Red Hat Linux Based Distros like:

• Red Hat Enterprise Linux
• Oracle Enterprise Linux
• Rocky Linux
• AlmaLinux

Moreover, the broadcom-wl Driver Supports the following Broadcom Wireless Chipsets:

• BCM4311
• BCM4312

• BCM4352
• BCM4360
• BCM43142
• BCM43224
• BCM43225
