Tried this but no dice.
Also tried followed the steps near the bottom of this thread (which look similar) but on the last step I get:
$ sudo modprobe -v wl
insmod /lib/modules/4.10.0-32-generic/updates/dkms/wl.ko
modprobe: ERROR: could not insert 'wl': Required key not available
I'm not getting any kind of connectivity, and have to connect to my router with ethernet.
