Debian does not recognize broadcom wireless (BCM43602) as wlan0 interface

I'm struggling to get my wireless card detected as wlan0 on a new Debian install (3.16.0-4-amd64). The wireless PCI device is visible as follows. $ lspci -knn | grep Net -A2 04:00.0 Network controller : Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01) Subsystem: Apple Inc.

Device [106b:00f6] Kernel driver in use: tg3 With the help of [this tip online](https://askubuntu.com/questions/622988/wifi-issues-with-macbook-pro-retina-early-2015-12-2-on-ubuntu-15-04) , I placed a download of brcmfmac43602 in /lib/firmware/brcm. I've since restarted and attempted to add the module to with modprobe brcmfmac. Still, I'm unable to see the network interface, as displayed below. $ ip link show 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 98:5a:eb:c6:cf:4d brd ff:ff:ff:ff:ff:ff Any pointers on what I may have overlooked would be greatly appreciated.
