Centrino Wireless-N + WiMAX 6150 recognizes Wifi but doesn't connect

Let's see if there are any clues in:

Code:

---

cat /var/log/syslog | grep etwork | tail -n20

Also, I suspect you'll have better luck if your router is set to WPA2 only, not any mixed mode. Please see attached.

Here you go:

We see eth0, that is, your wired ethernet, connecting perfectly. Please detach the ethernet cable, try to connect with wireless and try again.

I've tried it without the ethernet cable, and it is still not connecting.

I've redone the

without ethernet cable and here's the results, if that'll help.

When you click the Network Manager icon and edit connections, is IPv6 set to Ignore? That seems to be a common Google hit searching for this mysterious listing:

Is your router reset to WPA2 only?

I, um, don't know how to edit my router. It was set up by someone else.

Also, the IPv6 is set to automatic; I've double checked.

I'm very sorry if I didn't make myself clear. I'm requesting that you set IPv6 to Ignore and not automatic.

Oh, sorry.
I've set the IPv6 setting to ignore now, but it still won't connect.

May I see:
