Thread: Ubuntu 11.10 Dell Inspiron Wireless Issues - Broadcom BCM4312

hi,

upgraded 11.10 10.04 (incremental upgrades through each version). facing wireless issues else has -- if click on networking icon in top right, "enable wireless" greyed out , unclickable. wired ethernet connectivity fine.

i've seemingly followed of steps https://help.ubuntu.com/community/wi...driver/bcm43xx , http://ubuntuforums.org/showthread.php?t=1604868.

here outputs cover approaches outlined in above 2 links:

i've setup bad combination of number of solutions, or i'm missing something. read in 1 post order in install/uninstall drivers (firmware-b43-installer, b43-fwcutter, bcmwl-kernel-source) relevant? dumb question, once installed, need activate them? don't see them listed on additional drivers (see above screenshot). there command need manually issue? blacklist file?

either way - appreciate this! frustrating.
