I was trying to connect to wi-fi with lubuntu but I could not, I don't know exactly what is the problem, I used nm-applet and that was the result:

    nm-applet

** (nm-applet:13926): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

(nm-applet:13926): nm-applet-WARNING **: Failed to register as an agent: (32) An agent with this ID is already registered for this user.
nm-applet-Message: using fallback from indicator to GtkStatusIcon

UPDATE:

So I re-install it and tried again, the result as following:

family@family-HP-Compaq-6735s:~$ lspci -knn | grep Net -A2
06:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

  • Please [edit] your question and add output of `lspci -knn | grep Net -A2` terminal command. – Pilot6 Jun 11 '15 at 19:40

If you can connect to internet by wire, then just run in terminal

sudo apt-get install bcmwl-kernel-source
sudo modprobe -r b43 bcma

If you can't connect another way, then use THIS METHOD

For me, installing 'at-spi2-core' allowed me to run nm-applet successfully, and connect to a wifi network.

sudo apt install at-spi2-core
