I am having DNS problems since upgrading to Precise from Lucid yesterday.

DNS sometimes works but is very slow.

These problems are just like others are having but I'm wondering if someone can help as I have slightly different specifics.

I have read this

"I really don’t want a local resolver, how can I turn it off? To turn off dnsmasq in Network Manager, you need to edit >/etc/NetworkManager/NetworkManager.conf and comment the “dns=dnsmasq” line (put a # in >front of it) then do a “sudo restart network-manager”."

I do not have this line to comment. Checking in Synaptic Package Manager reveals that dnsmasq isn't install (dnsmasq-base is).

Editing / creating connections using network manager GUI (and specifying DNS servers) doesn't help; ubuntu is not respecting user GUI set DNS servers. Should these GUI tools not work?

"I use static IP configuration, where should I put my DNS configuration? The DNS configuration for a static interface should go as “dns-nameservers”, “dns->search” and “dns-domain” entries added to the interface in /etc/network/interfaces"

Are any examples of this available? My /etc/network/interfaces is extremely sparse.

For now I have edited /etc/resolv.conf replacing nameserver 127.0.0.1 with that of my DNS server (my broadband router), but I don't know how long this fix will last before the file is overwritten by this new system (dnsmasq?).
