GNU/Linux CentOS Stream 9 Installing Broadcom WiFi Driver Offline

Hi! The Tutorial shows you Step-by-Step How to Download and Install Broadcom Wireless Driver without Internet Access in CentOS Stream 9 64-bit GNU/Linux Desktops.

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

Most noteworthy: to achieve this Setup you simply need any Online Computer with a Browser and a USB Stick to Copy the downloaded Packages.

But if you dispose of an Android Mobile Phone with Internet Acces, then an Easier Solution should be of using it! See: Internet Connection USB Tethering Guide.

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 CentOS Stream 9 kmod-wl Driver Supports the following Broadcom Wireless Chipsets:

• BCM4352
• BCM4360
• BCM43142
• BCM43224
• BCM43225
• BCM43227
• BCM43228

But for BCM4306, BCM4309, and BCM4318 see instead: B43 Wireless Driver.

Last, for Mac 2018/2020 T2 Chip Support you should see instead: Brcmfmac Driver Apple Firmware Setup Guide!
