I'm using Ubuntu 14.04 on my laptop and I can't connect to a specific WiFi networks. I managed to connect to others wifi networks in the past without any problem, and other devices (another laptop with Windows 7 and some Android smarthphones) were also able to connect to this WiFi network. Furthermore, this laptop can connect to the same router through the ethernet cable. So, as a resume, the problem is just between this particular device and this particular WiFi network.

Any hint about what may be happening?

I already tried solutions proposed on these questions but it didn't worked:

Can't connect to specific wifi network Can't connect to specific WiFi with 13.04

It seems that I don't have the iwlwifi but the wl instead. I also tried following those steps but replacing "iwlwifi" with "wl" but nothing.

From what I found on ubuntuforums.org you should

sudo apt-get purge bcmwl-kernel-source

reboot and you may need to blacklist b43 and/or ssb but you can try this after a reboot one line at a time and see if you are able to connect

sudo modprobe -r b43
sudo modprobe -r ssb

If you are able to connect only with using the modprobe -r b43 then echo "blacklist b43" | sudo tee /etc/modprobe.d/b43.conf

If it also took the modprobe -r ssb to connect then do both echo "blacklist b43" | sudo tee /etc/modprobe.d/b43.conf and echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/b43.conf and wifi should connect
