I'm pretty new to Linux and Ubuntu. I just installed the Lubuntu on my mother's old laptop to replace XP. But after the installation I was unable to connect to wireless network. For at least a week I've been hunting this forum and google for solutions but nothing seems to work. It works pretty well when wired to my router. Also when I do updates or installations of b43 whenever I have to restart or shut down it stays on a black screen or hangs on the Lubuntu logo with the dots. I usually have press the power button to shut it off fully. So I'm not even sure if the updates gets processed. Idk what to do I'm so lost right now. I will be grateful if someone can give me a solution. I would like to my moms laptop to be working as soon as possible(its a delayed mother's day gift)

ET : My results to "lspci -nn | grep 0280" are

06:05.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

ET: The Laptop is an Hp Pavilion DV4305us

Please hook up the ethernet temporarily and open a terminal and do:

sudo apt-get update
sudo apt-get purge bcmwl-kernel-source

If the latter isn't installed, that's fine, just continue.

sudo apt-get install firmware-b43-installer

Detach the ethernet. Next, do:

sudo modprobe -r ssb
sudo modprobe -r b43
sudo modprobe b43

Does the wireless come to life?

You may be able to resolve the shutdown issue with a complete update:

sudo apt-get dist-upgrade

After it completes, does it reboot as expected?

  • I have tried doing that many times but when it says to reboot or shut down I always get stuck on the lubuntu logo or a black screen. It never fully reboots/ shuts down, I end up having to do a cold shutting by press the power button. – MyaK May 31 '15 at 00:13
  • Please see my edit above. – chili555 May 31 '15 at 00:19
  • HI, I did but my computer doesn't shut down/reboot very well, should I still try those commands? – MyaK May 31 '15 at 00:25
  • Yes, please do. – chili555 May 31 '15 at 00:35
  • Hi, I tried the sudo modprobe codes. No luck with wifi, should I go ahead with the updates? – MyaK May 31 '15 at 01:32
  • also I just realised I downloaded the 15. something version of Lubuntu, would it be better is I install the 14.10 version? – MyaK May 31 '15 at 02:06
  • Yes, update; the fix for your shutdown issue may be one of the updates. No, do not install an older Ubuntu version. – chili555 May 31 '15 at 12:43
  • I did the update, but still does not shut down – MyaK May 31 '15 at 19:58
  • Are you running Gnome? Please see: http://askubuntu.com/questions/616571/laptop-doesnt-power-off-on-shutdown-after-upgrade-to-15-04-and-gnome-3-16 – chili555 May 31 '15 at 21:09
  • I don't believe so, I literally only installed lubuntu – MyaK May 31 '15 at 21:36
  • Sorry about my mis-step. Of course, you are running LXDE and not Gnome. Sorry. If you try to shut down from the terminal: sudo halt -pdoes it shut down? If not, are there informative messages in the terminal? – chili555 May 31 '15 at 21:46
  • I tried that, still does not shut down. Some quick message comes up but it does not seem like an error message. – MyaK May 31 '15 at 22:38
  • I'm sorry, I am not a shutdown expert. I will be happy to troubleshoot the wireless when shutdown is fixed. – chili555 May 31 '15 at 23:18
