View Full Version : [SOLVED] Broadcom Wireless don't broadcast in 11.04

May 2nd, 2011, 08:31 PM
I have a Dell Vostro 1400 with a BCM4311 Broadcom wireless card that I just reinstalled with 11.04 from 10.04. I have the drives installed and it seams to be working when i run the 'Additional Drives', but I can't get the wireless adapter broadcasting. I followed the instructions given in the knowledge base on installing Broadcom Wireless, to see if I could get it running and that is where I saw the difference between the example and my computer when writing the 'sudo lshw -C network' command. In the example it said it was broadcasting under configuration (just like my wired networks below) and in mine it does not (see below for copy past). I can't find a tickbox in the systemtray to enable the wirless networking that I had before the update to 11.04 (the 'Enable Networking' tickbox is still there and the wired network works fine - that is how I got online to do this post). I have the hardware switch turned on and I have been in the BIOS and made sure that the Wireless is enabled.

Anyone who knows what could be wrong? Where could I go from here?

I did the following and it helped me:

Steve, I have the same wireless network card; i.e. "Broadcom Corporation BCM4311", and the same problem (no wireless connection, even I cannot see the list of wireless networks) after the 11.04 upgrade. My problem is solved after removing "bcmwl-kernel-source" by using Synaptic Package Manager, then installing "firmware-b43-installer" and "b43-fwcutter" again by Synaptic Package Manager. I hope it solves your problem, too.
