Wireless connection dropped after switching router - Lubuntu

[pedroso]

I recently switched to a new router, and my wireless has stopped connecting. I can connect fine from other computers, as well as with cable. I can see the wireless access points from the drop-down list on the menu. But when I enter the password nothing happens. I am wondering what I am doing wrong, and if I have to set it up manually, but I don't know the commands to do that. I'm using Lubuntu 12.10 on an IBM Thinkpad T42.

This is the result from "iwconfig":

Is it a "hidden" network? If yes, broadcast the ESSID

[pedroso]

It isn't hidden, I can see it but not connect to it.

Does your ipw2100 do WPA2? Some don't.

sudo iwlist eth1 auth

[pedroso]

Yes. WPA and WPA2

Check also "iwlist chan". If the channel is set to "auto", maybe the driver only has 11 and the router broadcasts on 12 or 13?! If so, set a fixed channel.
