In command ifconfig it will show wlan0 when your wifi is enabled. so , you have to enable it from network-manager.

check your wireless card is not blocked using command

rfkill list

if blocking then make them unblocked using command

sudo  rfkill unblock wifi
  • rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no

  • may be wireless driver not installed ? check sudo lshw -C network | grep driver . output should be like ` broadcast=yes driver=iwlwifi driverversion=3.13.0-24-gene` if not installed then try sudo apt-get install firmware-b43-installer

As for the wireless, I suggest you try the newer firmware file. First, back up the existing file:

cd /lib/firmware
sudo mv iwlwifi-7260-7.ucode  iwlwifi-7260-7.ucode.bak

Now download the newer file:

sudo wget https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode

Reboot and tell us if it works better now.

  • mv: cannot stat ‘iwlwifi-7260-7.ucode’: No such file or directory so I am going to do the next best thing and go ahead and install the driver
