There'll be databases showing what device matches this Mac to confirm
it's your wifi interface.  I'll assume you've not plugged in the wired
cable and when you do it's eth0

Only one interface?  No lo (loopback)

Hopefully pan (bluetooth networking) isn't messing things up here.

Excellent.  Your machine is successfully connecting outside itself over
wifi.

My mistake it's -i for interface.  Of course this is less useful as we
see your ping gets to the gateway.

Okay that's what dhcp decided.

Right this is less good, your router isn't letting you connect out.

I think DNS is failing on the router as it can reach out.

By router I mean wifi router, I should say access point.  I think I have
an idea.  Your traceroute before showed: 

 1  10.219.60.1
(10.219.60.1)  26.547 ms  26.505 ms  26.445 ms

Which is a completely different rfc1918 range.  So I am guessing you're
plugging in to your cable router which is doing valid dhcp and dns etc.
When wireless you're using something that doesn't.

Is the wifi access point separate to the cable router?  If so can you
disable dhcp on it?  I assume it's plugged in to the cable router?  If
it's the same device, are there configuration options separately on the
wifi side?  Can any other device, mobile phone/psp even mac/win machines
use wifi successfully?
