Hi. I'm a begginer in ubuntu. I just installed de latest version (64 bits), but the wifi wont show any networks. I read that is a common problem but did not find the solution for my specific model (C845 SP4333KL). From what i read in other threads I put some commands on the console and showed this.
Thanks in advance for your help
