A single ping is never enough to troubleshoot a connection issue as it
could be a DNS issue, route, or something else. There are several things
you could do:
1. Perform a "traceroute www.google.com" or other site you
are having issues with. You may find a hop in the route taken
that points to an issue.
2. Do several "host -v www.google.com" or other site you have
problems with. Look at the last line ("Received xx bytes from
[ip-address-of-dns-server]#53 in yy ms"). Check the address of
the DNS server to make sure it's correct and look at the "yy ms"
bit to see if the server is being pokey.
