PC says Cable unplugged but is plugged in

Asked by Lovell Flinn

I am on another PC asking this question. I have a PC with Ubuntu that says the cable in unplugged. I have used 3 different cables.. I am now thinking there is some problem with my Ubuntu 11. 10 OS and is not reconizing that the cable is there.

Is any help that can make this work?

Hi ,

it will be little difficult now , cuz we probably will ask you for some info and you must get this info from a terminal on the NON working PC.

So you must get in the process to transferring the files from non working pc to the working pc and paste the results here.

Go to the Non working PC and open a Terminal by pressing Ctrl+Alt+t combo keys.

Then write carefully bellow commands

+++++++++++++++++++++++++++++++++
ifconfig >> ifconfig.txt
sudo lshw -C network >> lshw.txt
nmcli nm status >> nmcli.txt
+++++++++++++++++++++++++++++++++

We want the contents of all text files You will find them in your home directory.

Now , BEFORE ALL ABOVE STEPS , try something easy , of course from the non working PC.

Open a terminal and write

++++++++++++++++++++++++
nmcli nm enable
++++++++++++++++++++++++

see if above command do the trick.

If not the try another easy thing ...
from terminal again
+++++++++++++++++++++++++
gksudo nm-connection-editor
+++++++++++++++++++++++++

you will see the window for editing connections. Be sure that "Available to all users" and "Connect automatically" are ticked .

Thanks

I thank you for your input, but as I was trying to upgrade to Ubuntu 12.04 the PC would connect to the internet, so evidently something in the 11.10 system had gone awry. But I didn't have complete luck in loading 12.04. So now a different problem.

Thank you all again for your help.
