no wifi adapter detected by Bodhi

Installed bodhi-4.5.0-64 onto a 2008 Macbook, 4.1 and am not seeing wireless options. Do I need to install something from apt first in order for Bodhi to pick up the built-in wifi adapter? The "network connection" GUI only shows the physical ethernet NIC. diagnostics: thufir@bot:~$ thufir@bot:~$ sudo lspci -vnn | grep -i net 02:00.0 Network controller : Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 03) 03:00.0 Ethernet controller : Marvell Technology Group Ltd. 88E8058 PCI-E Gigabit Ethernet Controller [11ab:436a] (rev 13 ) Subsystem: Marvell Technology Group Ltd.
