I have no problem with wired connection, but wifi is not even an option on my newly installed xubuntu 15.04. I found similar question (Wifi not detected Xubuntu 13.10) and run the commands in terminal, here is the output:

op@op:~$ lspci -knn | grep Net -A2
06:02.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)
    Subsystem: Hewlett-Packard Company Broadcom 802.11b/g WLAN [103c:1355]
    Kernel driver in use: wl
op@op:~$ lsmod | grep -e wl -e b43
wl                   6152192  1 
cfg80211              462848  1 wl

This is what I have after running it again:

op@op:~$ lsmod | grep -e wl -e b43
b43                   401408  0 
bcma                   49152  1 b43

ssb                    57344  1 b43

op@op:~$ sudo apt-get remove --purge bcmwl-kernel-source
[sudo] password for op:

Package 'bcmwl-kernel-source' is not installed, so not removed

op@op:~$ sudo apt-get install linux-firmware-nonfree
Reading package lists... Done

linux-firmware-nonfree is already the newest version.
The following packages were automatically installed and are no longer required:
  dkms linux-headers-generic linux-image-generic thermald
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 13 not upgraded.

No files to remove, no files to install and still no wifi.

Any ideas???

Here is what I tried and collected as much info as I could. Please look: Uninstalled all wifi drivers from the system:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get remove --purge linux-firmware-nonfree
sudo app-get autoremove

Restart. Restart hangs forever. Power Down. PC comes back up with “System program problem detected” Installing linux-firmware-nonfree

sudo apt-get install linux-firmware-nonfree Looks good so far:

Preparing to unpack .../linux-firmware-nonfree_1.16_all.deb ...
Unpacking linux-firmware-nonfree (1.16) ...
Setting up linux-firmware-nonfree (1.16) ...
op@op:~$

Unplug Ethernet cable and restart. no wifi please see screenshot: https://i.stack.imgur.com/KF9Vd.jpg Plug Ethernet cable back removing linux-firmware-nonfree installing bcmwl-kernel-source and it hangs after installing no prompt available system is workable just terminal hanging. Please see bellow: Loading new bcmwl-6.30.223.248+bdcom DKMS files... First Installation: checking all kernels... Building only for 3.19.0-28-generic Building for architecture i686 Building initial module for 3.19.0-28-generic Done.

wl: Running module version sanity check. - Original module - No original module exists within this kernel - Installation - Installing to /lib/modules/3.19.0-28-generic/updates/dkms/

depmod....

DKMS: install completed.

NO PROMPT! RESTARTING. Hangs on the Xubuntu logo, Doesn’t restart. Power down. Comes back same story. No wifi. Since this was not an issue in Xubuntu 14 should I downgrade?

    Just run the commands. The worst that can happen is you'll lose your WiFi connectivity, which you don't have. Can you edit in a direct link to the question you're referring to? – TheWanderer Sep 08 '15 at 00:31

  • Do the commands in the answer. I can confirm these work on 14.04. – TheWanderer Sep 08 '15 at 00:46
  • Did not help, I opened Software & Updates here is what it shows: – pripe Sep 08 '15 at 01:30
  • You need to reboot afterwards. Did you do that? – TheWanderer Sep 08 '15 at 01:32
  • Did not help, I opened Software & Updates here is what it shows: well how do I attach the screen shot? Yes I did reboot. anyway it shows that this device is not working. do not use. – pripe Sep 08 '15 at 01:36
  • Upload it to Imgur and link it in your question. – TheWanderer Sep 08 '15 at 01:38
  • Here is the link to the image: http://imgur.com/fUIKa9J when I said I reboot it, it actually was not true. the laptop was trying to reboot for 3 min. the xubuntu logo was going and going. I powered it down. – pripe Sep 08 '15 at 01:48
  • Select the other option there. It's a choice whether or not to use the device. There pretty bad phrasing on the option, so I can see where confusion might be an issue. – TheWanderer Sep 08 '15 at 01:50
  • When I changed it to the driver, just before finishing installing it, It froze the system for more than 10 min and I shut it down. When it came back there was no driver to choose in the software updater it is disappeared. – pripe Sep 08 '15 at 02:20
  • Does your WiFi work though? – TheWanderer Sep 08 '15 at 10:53
  • No I still do not have wifi This is the image of my wifi button which used to glow with windows xp http://imgur.com/JGLDbV4,UAnpxN6,y0A4OPd

    This is the image when my system froze during installation http://imgur.com/JGLDbV4,UAnpxN6,y0A4OPd#1

    This is image of problems detected when I shut down my laptop and boot it buck up. Same 20 minutes ago when I started my laptop for the first time today. http://imgur.com/JGLDbV4,UAnpxN6,y0A4OPd#2

    What should I do. Please help. Should I re install the generic free driver? Should I re install xubuntu? If yes please let me know how.

  • Try the commands in the answer to the other question again. You'll need to hook up to the internet using a wired connection. – TheWanderer Sep 08 '15 at 22:45
  • Still nothing. I did edit my question with new information if you can look please. – pripe Sep 09 '15 at 20:51
  • Swap the commands and reboot. – TheWanderer Sep 09 '15 at 20:53
  • install first then remove? – pripe Sep 09 '15 at 21:20
  • No. Install what you were trying to remove and remove what you were trying to install. – TheWanderer Sep 09 '15 at 21:21
  • As you said I removed linux-firware-free and instaling bcmwl-kernel Setting up bcmwl-kernel-source (6.30.223.248+bdcom-0ubuntu2) ... Loading new bcmwl-6.30.223.248+bdcom DKMS files...

  • Maybe try rebooting – TheWanderer Sep 10 '15 at 19:10
  • Hi Zacharee1, restart did not work, had to power down. Edited my question, added more info from terminal and screenshots. Should I down grade to 14 maybe? – pripe Sep 10 '15 at 19:38
  • You could try that – TheWanderer Sep 10 '15 at 19:39
  • Thank you Zacharee1 for sticking with me for so many days :)) Though problem was solved with the other suggestions I've learned a lot from you. – pripe Sep 10 '15 at 23:07

You tried everything but the correct command. To install firmware for your adapter you need to purge bcmwl-kernel-source and run

sudo apt-get install firmware-b43-installer

  • This is awesome!!! Thank you, Thank you, Thank you Pilot6! Wireless works now! I was truly looking through the questions for similarity but did not see the one you suggested as duplicate. I'm using Linux only for 2 months so it is all new for me. What do I do with my question since it is duplicate? Delete it? Sorry it doesn't let me to do the vote for you since I have less then 15 reputations (what ever it is :)) – pripe Sep 10 '15 at 23:05
  • @pripe You are welcome. Just leave the question as it is. It wall show the way to other people with similar problems. – Pilot6 Sep 11 '15 at 07:18
