I'm trying to set up CentOS 7 on a Dell Precision M3800 and can't get the wireless working - the only option under network settings is "wired". Any ideas how I can get a working driver?

$ lspci | grep Wireless
06:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)
$ uname -r

BCM4352 has been reported as working on CentOS 7.1.

Step 1: Determining WLAN chip and installing dependencies
Step 2: Downloading and extracting Broadcom driver archive
Step 3a: Compiling the Broadcom driver module (on EL6 and EL7)
Step 3b: Compiling the Broadcom driver module (specifics required for EL7)
Step 4a: Loading the driver module into kernel
Step 4b: Loading the driver module into kernel on boot time

Broadcom chip models tested and reported as working


You might also try the El Repo walkthrough. It has you install the Broadcom driver as a sourceless binary. It worked well for my machine, which runs Centos 7.3 (Kernel: Linux 3.10.0-862.11.6.el7.x86_64). Note that the Broadcom site says it supports Broadcom adapters for versions BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based hardware, but it exclude version BCM4331 (the version I use). I found that it works fine for this version. Hope this is helpful.
