internet connection doesn't work

Asked by Harold Smith

I am new to Linux and Ubuntu, so this may be something dumb. I just built a new computer from a barebones kit. It has an Asus m2n-mx se plus motherboard with an Athlon 64 x2 5000+ processor and 2G RAM. I installed ubuntu 8.10 from a downloaded CD, and almost everything seems to work fine, but I cannot connect to the internet. The motherboard has an ethernet port built in, which ubuntu detected and called eth0. However, any attempt to connect (to a known good connection, the one I am using with my Windows box to send this) fails.

ubuntu seems to boot okay, and everything seems to work except the internet. Left-clicking on the network icon (which shows no connection) shows eth0, and I can click on that and the icon changes to show a connection, but it won't work. Any attempt to actually connect resets the icon to no connection.

I thought it might be a hardware problem with the motherboard's port, so I added a PCI network card, and that, too, is auto detected, and called eth1. It behaves the same. I tried the stuff in the Tools to Help section of the ubuntu documentation, such as pinging, but it always fails. No packets ever go anywhere.

What am I overlooking, and what can I do? Without the ability to connect to the internet, the computer is pretty useless.

Thanks.

My internet is through the cable company. The modem is one they supplied, and it is connected through a router that feeds several rooms. At the moment, only the Windows computer, the ubuntu computer, and an old box in the basement running Fedora are connected to it. The windows box is what I am using to communicate now. The Fedora box also worked the last time I tried it, but that has been a couple of months ago.

The ISP is Nulink, the local cable company. The connection is, IIRC, 3 MB/s. It's fast enough, anyway.

Is that what you needed to know?

Step 1:
Go to your Network control panel.
Follow steps : Taskbar >> System >> Administration >> Network.

Step 2:
Then click on the Unlock button and then it will ask for Administrative password, Enter your Password. and click Authenticate so that it will unlock the locked features.

Step 3:
Click on Wired connection and then its properties, it will show you “Connection setting tab” select “Automatic configuration (DHCP)” from the list and click OK.

Step 4:
Select Point to Point connection, and go to its properties. It will pop up the pppo properties.
Check the “Enable this connection”, and select “PPPoE connection type” and Enter the account data (Username and Password)in specified boxes,

Step 5:
Go to Modem tab from same Window, select the Ethernet interface (Generally the eth0)
Go to option tab select all check boxes. and then OK. and close.

Now everytime you want to connect to net, just click on LAN Icon on taskbar and go to Dial Up connections and click on Connect to pppOe via modem and get connectiviy.

So now just start your Firefox and start browsing the internet from your Ubuntu.

At System >> Administration >> the closest I get to 'Network' is 'Network Tools', and there is no unlock button.

Obviously I am doing something wrong, but I am too new at this to know what it might be.

Goto : System -->Preferences-->Network Configuration

Then in wired , click on add {"+"}

Check connect automatically

Goto IPV4 setting tab , see to that method is Automatic DHCP

Cross verify , in 192.168.1.1 , your router page , if DHCP is enable

I think I did as described, except for the Cross Verify part. I don't know what that means or how to do it.

I got a network connection, as before, that lasted several seconds and disconnected. This is the same behavior I've had all along.

Okay, it appears to me that ubuntu will not work for me. How do I remove it
so that I can try a different OS?
