Yes, I've looked at several other posts, and other sites trying to figure out what's up, but I've followed the steps, and had no success.
Note that I'm a relative newbie to setting up wireless on Ubuntu, so please feel free to suggest dumb errors like "is it on", I very likely missed something fundamental.
Output from a couple of commands:
$ lspci | grep
0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 01)
lo no wireless extensions.
eth0 no wireless extensions.
Additional Drivers says "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)"
sudo apt-get install bcmwl-kernel-source
It just gives errors:
