I am not able to establish a wired network connection between two computers on which I just installed Ubuntu 10.04.

I am new to this environment. Unlike in the Windows environment, where it happens by just connecting them with a cable, Ubuntu keeps flashing a notification saying "Wired network disconnected". Am I missing a driver or something?

I am able to connect to the wi-fi router without issue. The wired connection is just not working.

Has the two machines assigned ip addresses of the same range? Say like: and Are you able to ping one from the other? – Ajo Augustine Apr 28 '11 at 13:31
Are you using a cross-over cable, or do you have a switch or hub in-between? – Ewan Leith Apr 28 '11 at 13:42
Thanks..@Ajo Augustine: after i read your reply i tried to assign static ip addresses to both the systems but got stuck on what should be the DNS server. IP Addresses: and; Netmask:; Gateway:; Don't know what should the DNS server be. any suggestion please? @Ewan Leith: I am using a cross-over cable. – Deep Apr 28 '11 at 13:50
you don't need a DNS server to connect them. But you can always use some free dns servers (like google's – pconcepcion Apr 28 '11 at 13:58
