Ubuntu wired connection missing default gateway

rioguia · 08-30-2009, 03:36 PM

My 9.04 Ubuntu wired connection on my Dell Inspiron appears to be fine when I look at the configuration files and gui interfaces. It will ping my network fine and query dig successfully but no other services work. After I open a terminal and route -n shows no gateway

I added a gateway like below.
sudo route add default gw xxx.xxx.xxx.xxx (my route IP)

Then all services work fine.

What am I doing wrong?

Hello rioguia,

I'm not familiar with ubuntu. But please post if you're using DHCP.

Sorry for the lack of specifics.
I am using a static IP for this wired connection directly to a Netgear router.

Simply spoken, if you don't use DHCP there must be a configurationfile somewhere in your system where the gateway is specified. For example in Slackware there is a /etc/rc.d/rc.inet1.conf with a line:

Code:

gateway=""

where I can insert my gateway (if I didn't use DHCP).
