View Full Version : [ubuntu] 9.04 new install, no wired internet connection

January 7th, 2010, 02:47 AM
Problem: Can't connect to internet in FireFox via wired connection "AutoEth0" per networking menu.

PC Details ; IBM netvista PC.2002. 40 GB HD, 256 RAM, DSL wired connection via Ethernet card. Single partition new 9.04 install= all Ubuntu.

I have searched the forums and google for answers using various keyword searches. I have tried several suggested "tricks" , been through all the menus and tabs, and tried to follow what others have done. I am still stumped . The ethernet card appears to be working, but is the system seeing it as Eth0? Somehow disabled? Turned off? . I have a second PC running Ubuntu 8.04 (over 2 years now!) that has run great and wired connection simply worked after install. From other posts I ran some commands that others posted during similar trouble shooting. I used the output below and compared to 8.04 PC output looking for errors?...still stumped, but feel like I am learning something and want to get this 9.04 box connected instead of loading 8.04 hoping "that will work" as a solution! Trouble shooting command output from new 9.04 PC, follows...what am I missing???...TIA!

Edit : OK. after posting I have to figure out how to get all this code formatted correctly

You don't have an IP
sudo dhclient eth0
what is ping www.google.com output then?
Do you connect to a router that gives you an IP automatically?

Can you set your modem to act as a router?
If not, you need to dial from your linux box.
Have you tried doing it graphicaly from 'Network Connections' applet?
Right click on the applet and Edit Connections
Select DSL and Add
Any luck?

Not sure if I can set my modem to act as router. Will ask Verizon. Also I have a router, maybe I'll set it up.
All part of the learning curve.
OK I follow you on > add > dsl >, will try that and post back 2morow.
I think I got spoiled with my 8.04 PC "that just worked" from the getgo.
I expected 9.04 to be a more robust release and act accordingly and the same.

Thanks for your help

No problem
If that doesn't work you may also want to check running

But as you can read in that guide:
"Warning: This guide is quite old now! Newer versions of Ubuntu use Network Manager (nice GUI) to manage DSL connections."
