    This typically means the wireless switch or key combination is set to OFF. Can you switch it? Please post:
    Code:
    rfkill list all
    Thanks.

    Having the same problems. Just bought a Lenovo G780 with Atheros Wi-Fi card which isn't working. It cannot find networks and entering the SSID manual also doesn't work because it will not connect.

    Google'd it but did not find anything real useful.

    Just got a pop-up for enabling the Broadcom Wi-Fi driver and enabled it. But that didn't make it work unfortunately

    enabling the Broadcom Wi-Fi driver
    Just bought a Lenovo G780 with Atheros Wi-Fi card
    Hmmm. Maybe we'll work on the Broadcom wireless card. Afterwards, let's fix the Atheros wired ethernet.

    Please post:
    Code:
    lspci -nn | grep 0280
    lsmod | grep -e brcm -e b43 -e wl

    Excuse me for my minor mistake there. Was mixing it up indeed.

    Code:
    ubuntu@ubuntu:~$ lspci -nn | grep 0280

    No problem at all; I've made worse today and probably more of them!

    Ahhh, the infamous 14e4:4727! Just my luck. This is a rare duck that seems to have two ways to get it going. There are threads around here that swear one way works and the other doesn't. First, let's remove wl and see what happens.
    Code:
    sudo modprobe -r wl
    sudo iwlist wlan0 scan
    If it scans, we can get it to connect. We'll need to remove the STA driver.

    If not, remove brcmsmac:
    Code:
    sudo modprobe -r brcmsmac
    sudo modprobe -r bcma
    And now reload wl:
    Code:
    sudo modprobe wl
    sudo iwlist eth1 scan
    Now which combination works? We'll amend a file or two and make it persistent.

    Okay so I tried those commands. After the first two it reported "wlan0 No scan results" so I continued with the next sets of commands. The last one reports "eth1 Interface doesn't support scanning."

    Quite unfortunate, this is. Anything else you'd like to know?
