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)

op@op:~$ lsmod | grep -e wl -e b43
wl 6152192 1

This is what I have after running it again:
op@op:~$ lsmod | grep -e wl -e b43

op@op:~$ sudo apt-get remove --purge bcmwl-kernel-source

Package 'bcmwl-kernel-source' is not installed, so not removed
op@op:~$ sudo apt-get install linux-firmware-nonfree

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:

op@op:~$
Unplug Ethernet cable and restart. no wifi please see screenshot: https://i.sstatic.net/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.

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?
