Cannot connect to wifi.

Asked by James Alexander Caddick

I can no longer connect to wifi. Wifi was previously working. Wifi works on other devices. Can connect to internet with ethernet connection. I seem to be able to detect the network, but get an "Activation of network connection failed".

I ran the below command and got the below output:

sudo apt-get update; sudo apt-get install usbutils pciutils hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | grep -Ei 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nnk | grep -iA2 net; lsusb; nmcli g; sudo lshw -short; uname -a; sudo updatedb; dmesg | grep -E '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|RTL|rt2|RT2|rt3|RT3|rt5|RT5|rt6|RT6|rt7|RT7|usb|witch|wl';sudo dmidecode|grep -E 'anufact|roduct|erial|elease'; iwconfig; grep -E '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl' /etc/modprobe.d/*; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|grep -E 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; ls -lia /boot; grep tmpfs /etc/fstab; ubuntu-support-status || ubuntu-security-status; sudo update-pciids; sudo update-usbids; sudo lsmod
