Nice to have a couple of days off, but not to sit behind your computer to find a solution for my connection problem
Read and tried so many different possible sollutions, none seems to be working for me
Also tried to install networkmanager/Gnome/**, but get errors because of no internet connection
I'm stuck wright now, need some advise what to do or where to look for

The static address you gave to it is not valid.

networking typically runs automagically out of the box. If your having issues connecting you could be missing package(s) that are required per your installation.
clue: put the quoted text at the top of your

Code: Select all

/etc/network/interfaces 

where it should be/have been in the first place.

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or

sorry, is 127.0.0.1. Have to type everything because of no inet on other laptop

[Head_on_a_Stick]

is 127.0.0.1

That's still the wrong address.
