Ethernet connection not recognised.

Hi

Regrettably, Matt, I have tried this workaround by applying the changes for a fixed IP address, etc, as per the links you referred to but without success.
Post changes, the bootup displayed a message 'Waiting for Network Configuration' under the startup Ubuntu logo screen, and would take all of a minute to present the desktop.
Then the network connection symbol would be shown on the top toolbar (Eureka) but alas no internet connection when using the browser or email.

Did you set up a dns server ?

Please post the output of

Code:

cat /etc/network/interfaces

Code:

ping -c 3 8.8.8.8

Code:

nslookup www.slashdot.com

Kind regards

Hi Matt,
Done it! I continued researching the problem after my earlier post today and found more evidence of Network Manager causing serious problems since Adam was a lad.
So I removed NM in its entirity and edited /etc/network/interfaces to just recognise eth0 - as per http://ubuntuguide.org/wiki/Ubuntu_P...ork_Management
-------------------------------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
# auto lo
# iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.

auto eth0
iface eth0 inet dhcp
-----------------------------------------------------------------
Commented out the loopback two lines and inserting the last two lines.
I then configured eth0 using ifup
Restarted and hey presto - auto Internet access but regretfully with no icon in the system tray telling me that. Can you please suggest a howto for this?
Is there anything any else I should do, please, to make these changes robust?
Do you still want the outputs you requested?
My grateful thanks and kind regards,
Roger

I don't really know of one i'm afraid.

You could look at using wicd instead of network manager.

http://wicd.sourceforge.net/

Been a good while since i have looked at it though and i don't know if it integrates into the panel.
