After installing the firmware cut from wl_apsta.o in 2.6.20-9 (as described by Jeff), I now have wireless connectivity again without resorting to booting the 2.6.20-6 kernel.
One glitch though: The wireless light on my laptop no longer lights up as it does when using the 2.6.20-6 kernel. Pressing the activate button causes the light to flash briefly, but it will not stay lit. I have a BCM4306 rev02 wireless card. -- bcm43xx completely broken in feisty https://launchpad.net/bugs/85404 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
