Yeah, and I'm tired and its late, so I forgot step 0! Sorry, here it is,
along with the rest so its a complete story:
...
-1 - if 'netstat' shows a (wireless) device with a valid IP address, you
theoretically have
neworking up.
0 - ping that Ip address, if it answers then indeed the hardware drivers
are acting
like they think your networking is working.
1 - if 'ping' to a numeric IP address within your local wireless
network works,
then you've gotten connected to the local net fine, but you need to
make
sure DNS works:
2 - if 'ping' to a non-numeric IP address within your local wireless
network subnet
works, then you've got DNS working. Now
3 - if 'ping' to a NON-local IP address (by name OR by number, having
established
that DNS works) works, then you're 99% of the way home.
4 - NOW that we have established that IP networking is working right,
THEN try
your applications.
if '-1' fails, your networking isn't, you need to make the hardware work
AND get
all that nifty wireless infrastructure stuff going. (essid, all that)
if 0 fails, you are in a similar boat, just farther down the stream :-)
if 1 fails, then you may have route problems, or you may not actually
be connected
to the (wireless) network.
if 2 fails (but 1 works) then you need a DNS server - check
/etc/resolv.conf (or wherever
it is these days).
if 3 fails (but 1 and 2 works) then you almost certainly have a
routing issue - you need
a default route to the gateway. USUALLY you get this (and DNS server,
by the way)
from your DHCP server.
