Thank you for your help. This is what I did and saw:
In Terminal I entered 'gksu Mousepad /etc/hosts' and I made the two
first lines as you told me.
Then I entered 'nm-applet &'. The answer was not a simple OK but a
message I did not write down. I got the idea that something was not OK.
When I looked at the Desktop I noticed the network icon I missed
before has returned to the screen (2 monitors connected to each other
with a cross).
As you mentioned I tried to configure the wired connection manually.
The window 'Network Connections' has 5 tabs: wired/wireless/mobile
'wired' shows the existing situation: Auto eth0 - never (the word
'never' seems to pose the problem to me).
Also 3 buttons can be seen: add/edit/delete.
Editing the wired 'auto eth0' connection gives a submenu with 3 tabs:
wired/802.1 x security/IPv4 settings.
Under 'wired' one can choose to enable 2 items: connect automatically
and system setting. Both choices are unabled by default. I kept it
this way (I enabled both choices but that did not seem to make a
The subscreen also shows some values: MAC address: 00:D0:59:14:37:41
and MTU - automatic. I didn't change these values either.
Under 'IPv4 settings' one can choose among 5 methods: automatic
(DHCP)/automatic (DHCP) addresses only/manual/link-local only/shared
to other computers.
Only when I choose 'manual' the button 'OK' at the end becomes grey,
meaning that the changes I make into this menu (entered IP addresses
for pc/netmask/gateway and DNS servers) cannot be saved.
At the end I entered your last given command:
sudo /etc/init.d/networking restart. The answer was: reconfiguring
network interfaces [OK}.
Connection to the internet is still not possible. To me the problem
seems that I cannot give this laptop-pc an IP-address.
Do you have any more recommendations to improve the situation?
Thank you very much in advance, kind regards, Daan
