This is quite complicated because if I boot with the broken upgraded kernel (4.4.0-67) I cannot access Internet.
So I'm installing python-apport on my working kernel (4.4.0-66) and then I come back to the broken one to launch the request command. I did some basic test and noticed that kernel 4.4.0-67 miss the wifi modules. When I try to do the following command $ sudo modprobe iwlwifi I receive an error message that say that this module don't exists I attached the output of lsmod command on working and not working kernels, and there are a lot of missing modules in the broken one. So I think that the problem are the missing kernel modules ** Attachment added: "lsmod output" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674109/+attachment/4840439/+files/OUTPUT_lsmod.txt ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1674109 Title: Wifi network connection broken after upgrading to 4.4.0-67 kernel Status in linux package in Ubuntu: Confirmed Bug description: Hi, I did an upgrade of my Ubuntu 16.04 and I installed last available kernel 4.4.0-67-generic.
