i am looking for help for getting my Broadcom Wlan card working on my laptop with Ubuntu. Until now i was not able to get it to work. Solutions i tried for now: 1. using the additional driver that can be installed via the ubuntu additional driver menu 2. using ndiswrapper with the appropriate Windows XP driver for the BCM4313

Both solutions seem to have the same problems. You can scan for available wlans (iwlist scan). Also wlan frontends from ubtuntu and kubuntu can find wlans. But connecting to them is not successful. Finally i did my tests using the wicd-client frontend.

Question: How can i fix the problem so i can connect to the network? How can i see what is going wrong?

My Hardware:

> lspci -vnn | grep 14e4

possible duplicate of How to install Broadcom wireless drivers? (BCM43xx) –  karel May 3 at 22:44
    
For Device "14e4:4727" under Ubuntu 14.04 LTS it is said there: "... Special Case #1 - This device uses the driver combination bcma and brcmsmac. It shouldn't be necessary to install anything at all. Required firmware is installed by default in the package linux-firmware. ..." This i can confirm, the wireless card was listed and wireless networks shown up. But i could not connect to any network. That makes me think the list is not complete? I will try the approach from "Jim Rogers" on the comments and will let you know, thanks. –  JavaBugger May 5 at 10:56
    
Write whatever you did down. In case it doesn't work, add what you did to your question which will help you to get a better answer. –  karel May 5 at 11:10

Hi, i reinstalled the system, and wow, i could connect to wlan. There was one thing i did differently this time: using ubuntu-desktop instead of kubuntu-desktop. That leads me to the assumption that the kde wlanfrontend messed it up. But i will not check my assumption because reinstallation will take 2 hours. One drawback was still there with the broadcom wireless card: I installed the ubuntu server edition, in installation procedure i could not use the wireless card. I needed to use the server edition because only the server edition can encrypt partitions, not entire disks. –  JavaBugger May 7 at 12:45

1 Answer 1

In my case, on a netbook that uses this chipset, the additional step of setting REGDOMAIN in /etc/default/crda to my country code allows the netbook to connect to wifi APs successfully using brcmsmac, even when unhibernating.
