ubuntu needs windows to connect to internet

Asked by JAMES on 2008-08-28

If I turn on computer and startup ubuntu it does not connect to internet by firefox or email. These did work at initial installation. My ifconfig is given below.
eth0 Link encap:Ethernet HWaddr 00:0d:61:81:66:ab
          inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0

Hi, James.

Is your netcomm box assigning IP addres to your ethernet card? Put another way: Is DHCP turned on in your netcomm box?

JAMES (jim1-exemail) said : #2

How do I find this out. I typed in the address for my netcomm but could see no ref to dhcp although this box works ok in windows/

JAMES (jim1-exemail) said : #3

It does show an ethernet address as 192.168.1.1
Is this what you mean?

Ok. Let's do it the other way around.

To get this card working in windows, did you type in any values for IP address, or you just didn't do anything and it worked on it's own?

JAMES (jim1-exemail) said : #5

initially the only number i typed in was the address for the netcomm box otherwise it was automatic - I did not have to do this when i started up ubuntu.

Ok. Probably, you have to tell Ubuntu where your "gateway" is.

Right click on the Network Manager icon and click on "Edit Connections ...". Depending on your Ubuntu version, you'll have to either Unlock the dialog window, or otherwise give your administrator's password. Do that.

Then, click on eth0, and then click on the Edit button.

After that, find the tab where you can set the IP address of the gateway and the DNS server, and put in 192.168.1.1 (your netcomm box). Sorry I can't give you the name of the tab I'm testing Xubuntu 8.10 and they changed that.

Hope it helps. I'll stay online.

JAMES (jim1-exemail) said : #7

THANKS. I am going to have to go out for 1hr and then I will return and
check and advise you.
Jim

I cannot find network manager....where is it?

The icon on your status bar, with the two little monitors.

JAMES (jim1-exemail) said : #10

Ok. Let's try the "hard" way ;) hehe

Open up a terminal. Type:

sudo mousepad /etc/network/interfaces (if you are in Xubuntu)

or

sudo gedit /etc/network/interfaces (if you are in Ubuntu)

It'll ask for your password, but you won't see asterisks or anything whn you type. Then, your text editor will pop up.
the text inside should look like this:

[begin file]

auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1

auto eth0

[end file]

If not, change the appropriate IP addresses. Save and close the editor.

Then issue the following commands:

sudo ifdown --force -a
sudo ifup -a

Then it should work.

 will try this and as i have several things to do my reply will probably
be quite a bit later.

Ok. That's probably it. Copy and paste the text I adapted to your description. Then save the file and run the other two commands.

It's almost 2 AM here in Venezuela, so I'll probably go to bed in a while :P
