Have you set the gateway and dns-server?

Have you set the gateway and dns-server?

Yes, I've simply added new wired connection through network manager by filling up IPv4 settings manually.

Also

sudo pppoeconf

don't work for me

Are your interfaces up? If you type ifconfig in a command prompt what comes back?

For some reason mine wouldn't come back up after updates. Reboot fixed it.

You have two cards with the same ip-address. Are both cards shown in the network manager?

You don't have to use pppoeconf any more. There is an option now in the network manager: http://help.ubuntu.com/9.10/internet...cting-dsl.html

Yes both are shown like this-
ifupdown(eth0)
ifupdown(eth1)

I am alredy done with adding up new dsl connection there also I've filled IPv4 setting manually only problem is I don't know what to fill up in service,mac address,search domains

You shouldn't have the same ip address on both network cards. Try changing one of the addresses to 192.168.1.2.

As I understand it, you don't have a router in your network and your pc is connected directly to your dsl modem and has to use this modem to dial into the internet.
When adding a new dsl connection:

• you can leave the fields "service" and "search domain" blank (if your internet service provider didn't tell you otherwise). The "mac address" is a unique address of your network card. At what point does the network manager ask for that?
• are you sure, you have to set the ip address manually? You very probably have to set the ip4 configuration to "automatic" to automatically get an ip address assigned by your internet service provider.

Yes, I don't have any router
As you suggested added new dsl connection leaving mac address blank
but it didn't worked
Do I need to add dsl connection along with the wired connection? what is difference between them?
I am having this problem on my laptop,what I did on my pc having Ubuntu 8.04 is simply sudo pppoeconf and it works very fine, But it don't works with ubuntu 9.10 is this bug https://bugs.launchpad.net/ubuntu/+s...er/+bug/453640 causing problem or what?
without internet connection how to fix it
