Commands to make Network Manager work

Asked by ealthuis on 2016-12-28

I have looked through similar questions, and found that I was not even able to enter commands mentioned

The computer can not connect to the router, so no Internet available, system works other wise.
Upgrade from 16.04LTS to 16.10
Computer is hardwired to the router, other hardwired and Wifi connections work fine.

sudo rfkill list
 gave no answer, after password came back with user name: ea@azura:~$

If you have a switch or keyboard shortcut to enable / disable the WiFi then press it.

 I have a symbol in the panel, when I disable it I end up with nothing.

Could it be caused by motherboard?? I have no access to the DVD drive either.

Just guessing

Its nothing to do with the panel. Does the system have a make and model? If. You are unsure then run:

sudo dmidecode -t 1

What is the output please?

After extensive discussion with the motherboard manufacturer, I was told to replace the DVD drive with a newer one.
I did and 16.04LTS booted without any problems. I also had ethernet.

From this I concluded that the problem with Ethernet was entirely with the installation (an upgrade in place).

I thank you for the effort you put in to resolve the issue. I believe an update of the network manager was the real fault for loosing the ethernet so completely not only on the computer in question, but also on a second one.
