I have a pretty frustrating issue with FreeBSD. I am a Linux user who decided to switch to FreeBSD because I liked the idea of the ports system that it uses. I decided to give it a try in a virtual machine on Linux Mint and it ran flawlessly (I had to setup the gui but the process was trivial) so I decided I'd try a switch from Linux Mint to FreeBSD on my physical machine... Well it turns out setting up FreeBSD on my physical machine is not as smooth of a process. The ifconfig command is not showing a wlan0 wireless interface, and FreeBSD is not able to detect my network card (an Intel Wireless AC 3160) through the dmesg command. I discovered FreeBSD 11.0 supports drivers for the Intel Wireless AC 3160 through the iwm driver, but since I am new to FreeBSD I am not sure how to setup this driver as well as the wlan0 interface to successfully use my network card. Any help to this problem or even just a link to the relevant information would be greatly appreciated.

The iwm driver is not in the GENERIC kernel. The man page man iwm specifies the methods required to pull the driver in. Either:

  • build a custom kernel
  • load at boot time with /boot/loader.conf
  • load at runtime with kldload

The man page does not appear to be online - but it is in the latest snapshot.

  • it is described here.
