Could it have something to do with this?

This is related to an ubuntu installation, and I know this problem due to having experienced it on my desktop.
Yesterday I done cat /etc/resolv.conf and got a "nameserver 127.0.0.1".

Specifically, on my desktop, I couldn't fix it until I changed a file named "base" into /etc/resolvconf/resolv.conf.d/. I had to write in it my ISP's IPs, because the script used to generate resolv.conf always changed it to "nameserver 192.168.1.1" which is the router's IP.
Changing the"base" file forces to add the ISP IPs to the one detected by the system.

Now switch on the 770: no "base" file nor resolv.conf.d subdir are present. Is it that another way to connect is used or am I facing the same problem?
I somewhere read that it is related to IPv6 issues and the Dlink router I am using; I was thinking of flashing the IPv6 kernel because I need the NFS functions, is there the possibility that my 770 stops connecting after that?

Thanks!
