05:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 07)

  • Please edit your question to add details of your network devices from the terminal: lspci -nn | grep -e 0200 -e 0280 Thanks.

Are the respective drivers loaded?

lsmod | grep -e iwl -e r8169 

If not, load them:

sudo modprobe iwlwifi
sudo modprobe r8169

Is the wifi blocked by the hardware switch?

rfkill list all

It appears that something has gone very wrong in the update. I suggest you reboot and get to the GRUB menu by interrupting the boot process with the SHIFT key: https://help.ubuntu.com/community/Grub2 Select Advanced options and boot into the previous kernel version, presumably 3.13.0-43-generic. When booted fully, open a terminal and remove 3.13.0-44-generic:

sudo apt-get purge linux-image-3.13.0-44-generic

Reboot and do:

sudo apt-get update && sudo apt-get -y upgrade

Reboot, presumably to x-44, and see if both devices are now working.

Once I have more information, I will edit this answer to refine the solution.

  • no, nothing is blocked. the drivers, the whole thing, was working fine yesterday.

  • lsmod | grep -e iwl -e r8169 displays nothing

  • sudo modprobe iwlwifi sudo modprobe r8169 both give module not found errors
