Hi, I am still not able to get over the problem. I get no connection from the MTNL internet from different places using the ethernet. I have an Acer Aspire One laptop and using Kubuntu 8.10. I recently upgraded the kernel. ifconfig shows an address in eth0 for inet6 but no address or mask for inet. I tried what Rony had said to manually edit /etc/network/interfaces or to use nano but both did not give any result. Sometimes, after the edit I get eth0 connection "unmanaged". I tried to change to "managed=true" but even that did not work. When I go to K->applications->system->network tools I can see that there is both ipv6 and ipv4 in lo but only ipv6 in eth0. I believe MTNL dhcp requires ipv4. Any workarounds? Thanking you in advance. Sanjay
