Dear All, Having a problem with getting the network with my MTNL modem through ethernet. I might add that I have MTNL ethernet modems (ADSL) in my home, my office and my father's office. However, though DHCP is enabled on all three, my laptop (Acer Aspire One) does not seem able to connect at any of the three. When I ask for a new connection after connecting the wire (the wire gets detected so I don't get the "no carrier" message) I get the state of device eth0 as "ip configuration" by hovering the cursor over the icon of Knetworkmanager. The ehternet light lights up on the router and the little light at the ethernet point on my laptop also lights up. So I think the cable is ok in all places. The desktops at all the three places are working. One curious thing is that Knetworkmanager tries to make a connection and gives the state for decive eth0 as "ip configuration" even when there is no wire in the ethernet jack if I ask for a new connection. In fact, even when there is no wire, I do not get the "no carrier" message. The connections at the mtnl router level are by PPPoE. The result I get for ifconfig is as follows: sanjay@sanjay-laptop:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1e:68:c7:8a:a8 inet6 addr: fe80::21e:68ff:fec7:8aa8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:1577058210 overruns:0 frame:0 TX packets:0 errors:0 dropped:15 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:219 Base address:0x2000

If there is any more information required please let me know. I am what they call a "noob" and learnt what linux means only about four months ago. I use Kubuntu 8.10 and have the Knetworkmanager on it. I have not installed nm v 0.7 or any other. With regards, Sanjay

You have no ip assigned. Is eth0 setup for DHCP Do cat /etc/network/interfaces and post the output.
Since it was working three days ago, something has changed. did you update anything?. Your lan port could have failed. manually setup eth0 with suitable ip and ping another machine on the network to confirm.
use pppoeconf for adsl connection

This is most probably a bug as I face the same problem with wired connections in my AAOne. Wireless works beautifully. Try stopping knetworkmanager and do your ip setup through command line. Your /etc/network/interfaces should have this entry.
auto eth0 iface eth0 inet dhcp
Use 'sudo nano /etc/network/interfaces'
After the edit, do 'sudo /etc/inet.d/networking restart'. Hope this helps.

Further to the above situation, today I had to use the wired connection on the AAO with no dhcp available and I simply closed knetworkmanager, manually edited the interfaces file and restarted networking. I was able to surf the net using Firefox.
