OK, another mystery. I added the patch from the CD, added DKMS from the CD, added the bcmwl-kernel-source package, which crashed the system. Backed out the bcmwl-kernel package. Then, recompiled the STA driver downloaded from Broadcom, cleaned up the /etc/init.d/wifi.sh script, dropped and reloaded the newly compiled wl module, restarted networking, and voila! , the blue light blinks red and blue and the wireless interface is now working. But, wifi-radar still can’t connect.

Hey, maybe that’s what that little antenna symbol in the top toolbar is… Click, I can see the network offered; click, and I’m connected! Whoof. Almost an entire week since we started this upgrade, and five days of fighting with drivers and configurations, and we are back mobile-prepared again, just hours before starting on our week-long road trip. Now, if it will only survive a reboot…
