I can't get wifi to work on Ubuntu. I'm on Ubuntu 11.10 and I have a Broadcom controller that requires a BCM4311 driver. I unblacklisted it.
and I downloaded the replacement driver. I did the command "rfkill" and it said it was unblocked. It also says it is activated in the proprietary drivers application. I have a dell latitude d531. I don't know what else to do.
