[ubuntu] After hibernate, lucid wireless stopped working

view full story

http://ubuntuforums.org – I recently installed 10.04 and everything Just Worked. Before Lucid, I was using 9.04 and had successfully gotten my Broadcom 4306 working perfectly... which is why I think the Lucid install went so perfectly. Well, after a botched hiberation (Dell Inspiron 9100), my wireless is dead in the water. I've tried "ifdown", "iwconfig", "/etc/init.d/network restart" and "force-reload", 'modprobe -r b43'... What can I do to get my wireless working again?! (HowTos)
