So that sounds very much like NetworkManager is working - you have a working network connection !

Yes, you mentioned earlier that you were running dnsmasq - that means you are running a local DNS service. Have you configured that with the address(es) of at least one external DNS resolver. As I read the description on Wikipedia, dnsmasq is a forwarder not a resolver - that means that it can't do the recursive lookups a resolver does, just forward queries to an outside resolver and cache the responses.
If you haven't told dnsmasq where to get it's answers from, then it won't be working for you.

I'm guessing that this disables using the local DNS service - if so then that's not fixing the problem (local DNS service not working), only fixing the symptom (by not trying to use the local service).
