Few things. 1) Disable IPv6. 2) try IP only connections. First try
pinging the loopback, then the address of the local box, the the
gateway, then another machine on the network then an external site,
like 4.2.2.2 Then try using a name like news.google.com. This will
tell you where things get mucked up.
Let us know the results and we can help further.
