Network not working after upgrading Ubuntu

So, I upgraded to 10.04 beta, and the network stopped working. Ping to local machines based on IP was working, but pining google resulted in host not found. Firefox was also not working...

After much R&D finally figured out that the problem was with the DNS resolver - which got overwritten during the upgrade somehow. The quick hack is to just edit the file and enter the DNS name servers. Here's the output :
vibhu@zion:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver xx.xx.xx.xx
nameserver xx.xx.xx.xx
Put the IP addresses of your name servers instead of the xx's

The puzzle which still exists is why the DNS is not put in automatically. Still looking at that
