While it is a good idea to have tshark, we already *know* that
the OP's machine

 - is trying to resolve via mDNS
 - *that* part is failing.

... because:

- the interface link seems to be up and sees a connection
- They said pinging by IP works


So the next step would be to find out why mDNS is failing.
You don't fix a bike by heaping tools on it :)
